1 | Version 1.39.0 (2019-11-07) |
| 2 | =========================== | |
| 3 | ||
| 4 | Language | |
| 5 | -------- | |
| 6 | - [You can now create `async` functions and blocks with `async fn`, `async move {}`, and | |
| 7 | `async {}` respectively, and you can now call `.await` on async expressions.][63209] | |
| 8 | - [You can now use certain attributes on function, closure, and function pointer | |
| 9 | parameters.][64010] These attributes include `cfg`, `cfg_attr`, `allow`, `warn`, | |
| 10 | `deny`, `forbid` as well as inert helper attributes used by procedural macro | |
| 11 | attributes applied to items. e.g. | |
| 12 | ```rust | |
| 13 | fn len( | |
| 14 | #[cfg(windows)] slice: &[u16], | |
| 15 | #[cfg(not(windows))] slice: &[u8], | |
| 16 | ) -> usize { | |
| 17 | slice.len() | |
| 18 | } | |
| 19 | ``` | |
| 20 | - [You can now take shared references to bind-by-move patterns in the `if` guards | |
| 21 | of `match` arms.][63118] e.g. | |
| 22 | ```rust | |
| 23 | fn main() { | |
| 24 | let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]); | |
| 25 | ||
| 26 | match array { | |
| 27 | nums | |
| 28 | // ---- `nums` is bound by move. | |
| 29 | if nums.iter().sum::<u8>() == 10 | |
| 30 | // ^------ `.iter()` implicitly takes a reference to `nums`. | |
| 31 | => { | |
| 32 | drop(nums); | |
| 33 | // ----------- Legal as `nums` was bound by move and so we have ownership. | |
| 34 | } | |
| 35 | _ => unreachable!(), | |
| 36 | } | |
| 37 | } | |
| 38 | ``` | |
| 39 | ||
| 40 | ||
| 41 | ||
| 42 | Compiler | |
| 43 | -------- | |
| 44 | - [Added tier 3\* support for the `i686-unknown-uefi` target.][64334] | |
| 45 | - [Added tier 3 support for the `sparc64-unknown-openbsd` target.][63595] | |
| 46 | - [rustc will now trim code snippets in diagnostics to fit in your terminal.][63402] | |
| 47 | **Note** Cargo currently doesn't use this feature. Refer to | |
| 48 | [cargo#7315][cargo/7315] to track this feature's progress. | |
| 49 | - [You can now pass `--show-output` argument to test binaries to print the | |
| 50 | output of successful tests.][62600] | |
| 51 | ||
| 52 | ||

| 54 | information on Rust's tiered platform support. | |
| 55 | ||
| 56 | Libraries | |
| 57 | --------- | |
| 58 | - [`Vec::new` and `String::new` are now `const` functions.][64028] | |
| 59 | - [`LinkedList::new` is now a `const` function.][63684] | |
| 60 | - [`str::len`, `[T]::len` and `str::as_bytes` are now `const` functions.][63770] | |
| 61 | - [The `abs`, `wrapping_abs`, and `overflowing_abs` numeric functions are | |
| 62 | now `const`.][63786] | |

| 71 | ----- | |
| 72 | - [You can now publish git dependencies if supplied with a `version`.][cargo/7237] | |
| 73 | - [The `--all` flag has been renamed to `--workspace`.][cargo/7241] Using | |
| 74 | `--all` is now deprecated. | |
| 75 | ||
| 76 | Misc | |
| 77 | ---- | |
| 78 | - [You can now pass `-Clinker` to rustdoc to control the linker used | |
| 79 | for compiling doctests.][63834] | |
| 80 | ||
| 81 | Compatibility Notes | |
| 82 | ------------------- | |
| 83 | - [Code that was previously accepted by the old borrow checker, but rejected by | |
| 84 | the NLL borrow checker is now a hard error in Rust 2018.][63565] This was | |
| 85 | previously a warning, and will also become a hard error in the Rust 2015 | |
| 86 | edition in the 1.40.0 release. | |
| 87 | - [`rustdoc` now requires `rustc` to be installed and in the same directory to | |
| 88 | run tests.][63827] This should improve performance when running a large | |
| 89 | amount of doctests. | |
| 90 | - [The `try!` macro will now issue a deprecation warning.][62672] It is | |
| 91 | recommended to use the `?` operator instead. | |
| 92 | - [`asinh(-0.0)` now correctly returns `-0.0`.][63698] Previously this | |
| 93 | returned `0.0`. | |

353 | Version 1.36.0 (2019-07-04) |
| 354 | ========================== | |
| 355 | ||
| 356 | Language | |
| 357 | -------- | |
| 358 | - [Non-Lexical Lifetimes are now enabled on the 2015 edition.][59114] | |
| 359 | - [The order of traits in trait objects no longer affects the semantics of that | |
| 360 | object.][59445] e.g. `dyn Send + fmt::Debug` is now equivalent to | |
| 361 | `dyn fmt::Debug + Send`, where this was previously not the case. | |
| 362 | ||
| 363 | Libraries | |
| 364 | --------- | |
| 365 | - [`HashMap`'s implementation has been replaced with `hashbrown::HashMap` implementation.][58623] | |
| 366 | - [`TryFromSliceError` now implements `From<Infallible>`.][60318] | |
| 367 | - [`mem::needs_drop` is now available as a const fn.][60364] | |
| 368 | - [`alloc::Layout::from_size_align_unchecked` is now available as a const fn.][60370] | |
| 369 | - [`String` now implements `BorrowMut<str>`.][60404] | |
| 370 | - [`io::Cursor` now implements `Default`.][60234] | |
| 371 | - [Both `NonNull::{dangling, cast}` are now const fns.][60244] | |
| 372 | - [The `alloc` crate is now stable.][59675] `alloc` allows you to use a subset | |
| 373 | of `std` (e.g. `Vec`, `Box`, `Arc`) in `#![no_std]` environments if the | |
| 374 | environment has access to heap memory allocation. | |
| 375 | - [`String` now implements `From<&String>`.][59825] | |
| 376 | - [You can now pass multiple arguments to the `dbg!` macro.][59826] `dbg!` will | |
| 377 | return a tuple of each argument when there is multiple arguments. | |
| 378 | - [`Result::{is_err, is_ok}` are now `#[must_use]` and will produce a warning if | |
| 379 | not used.][59648] | |

| 400 | Cargo | |
| 401 | ----- | |
| 402 | - [Cargo will now produce an error if you attempt to use the name of a required dependency as a feature.][cargo/6860] | |
| 403 | - [You can now pass the `--offline` flag to run cargo without accessing the network.][cargo/6934] | |

| 572 | ========================== | |
| 573 | ||
| 574 | Language | |
| 575 | -------- | |
| 576 | - [You can now use `#[deprecated = "reason"]`][58166] as a shorthand for | |
| 577 | `#[deprecated(note = "reason")]`. This was previously allowed by mistake | |
| 578 | but had no effect. | |
| 579 | - [You can now accept token streams in `#[attr()]`,`#[attr[]]`, and | |
| 580 | `#[attr{}]` procedural macros.][57367] | |
| 581 | - [You can now write `extern crate self as foo;`][57407] to import your | |

| 586 | -------- | |
| 587 | - [You can now target `riscv64imac-unknown-none-elf` and | |
| 588 | `riscv64gc-unknown-none-elf`.][58406] | |
| 589 | - [You can now enable linker plugin LTO optimisations with | |
| 590 | `-C linker-plugin-lto`.][58057] This allows rustc to compile your Rust code | |
| 591 | into LLVM bitcode allowing LLVM to perform LTO optimisations across C/C++ FFI | |
| 592 | boundaries. | |
| 593 | - [You can now target `powerpc64-unknown-freebsd`.][57809] | |
| 594 | ||
| 595 | ||
| 596 | Libraries | |
| 597 | --------- | |
| 598 | - [The trait bounds have been removed on some of `HashMap<K, V, S>`'s and | |
| 599 | `HashSet<T, S>`'s basic methods.][58370] Most notably you no longer require | |
| 600 | the `Hash` trait to create an iterator. | |
| 601 | - [The `Ord` trait bounds have been removed on some of `BinaryHeap<T>`'s basic | |
| 602 | methods.][58421] Most notably you no longer require the `Ord` trait to create | |
| 603 | an iterator. | |
| 604 | - [The methods `overflowing_neg` and `wrapping_neg` are now `const` functions | |
| 605 | for all numeric types.][58044] | |
| 606 | - [Indexing a `str` is now generic over all types that | |
| 607 | implement `SliceIndex<str>`.][57604] | |
| 608 | - [`str::trim`, `str::trim_matches`, `str::trim_{start, end}`, and | |
| 609 | `str::trim_{start, end}_matches` are now `#[must_use]`][57106] and will | |
| 610 | produce a warning if their returning type is unused. | |
| 611 | - [The methods `checked_pow`, `saturating_pow`, `wrapping_pow`, and | |
| 612 | `overflowing_pow` are now available for all numeric types.][57873] These are | |
| dc9dc135 | 613 | equivalent to methods such as `wrapping_add` for the `pow` operation. |

717 | Version 1.33.0 (2019-02-28) |
| 718 | ========================== | |
| 719 | ||
| 720 | Language | |
| 721 | -------- | |
| 722 | - [You can now use the `cfg(target_vendor)` attribute.][57465] E.g. | |
| 723 | `#[cfg(target_vendor="apple")] fn main() { println!("Hello Apple!"); }` | |
| 724 | - [Integer patterns such as in a match expression can now be exhaustive.][56362] | |
| 725 | E.g. You can have match statement on a `u8` that covers `0..=255` and | |
| 726 | you would no longer be required to have a `_ => unreachable!()` case. | |
| 727 | - [You can now have multiple patterns in `if let` and `while let` | |
| 728 | expressions.][57532] You can do this with the same syntax as a `match` | |
| 729 | expression. E.g. | |
| 730 | ```rust | |
| 731 | enum Creature { | |
| 732 | Crab(String), | |
| 733 | Lobster(String), | |
| 734 | Person(String), | |
| 735 | } | |
| 736 | ||
| 737 | fn main() { | |
| 738 | let state = Creature::Crab("Ferris"); | |
| 739 | ||
| 740 | if let Creature::Crab(name) | Creature::Person(name) = state { | |
| 741 | println!("This creature's name is: {}", name); | |
| 742 | } | |
| 743 | } | |
| 744 | ``` | |
| 745 | - [You can now have irrefutable `if let` and `while let` patterns.][57535] Using | |
| 746 | this feature will by default produce a warning as this behaviour can be | |
| 747 | unintuitive. E.g. `if let _ = 5 {}` | |
| 748 | - [You can now use `let` bindings, assignments, expression statements, | |
| 749 | and irrefutable pattern destructuring in const functions.][57175] | |
| 750 | - [You can now call unsafe const functions.][57067] E.g. | |
| 751 | ```rust | |
| 752 | const unsafe fn foo() -> i32 { 5 } | |
| 753 | const fn bar() -> i32 { | |
| 754 | unsafe { foo() } | |
| 755 | } | |
| 756 | ``` | |
| 757 | - [You can now specify multiple attributes in a `cfg_attr` attribute.][57332] | |
| 758 | E.g. `#[cfg_attr(all(), must_use, optimize)]` | |
| 759 | - [You can now specify a specific alignment with the `#[repr(packed)]` | |
| 760 | attribute.][57049] E.g. `#[repr(packed(2))] struct Foo(i16, i32);` is a struct | |
| 761 | with an alignment of 2 bytes and a size of 6 bytes. | |
| 762 | - [You can now import an item from a module as an `_`.][56303] This allows you to | |
| 763 | import a trait's impls, and not have the name in the namespace. E.g. | |
| 764 | ```rust | |
| 765 | use std::io::Read as _; | |
| 766 | ||
| 767 | // Allowed as there is only one `Read` in the module. | |
| 768 | pub trait Read {} | |
| 769 | ``` | |
| 770 | - [You may now use `Rc`, `Arc`, and `Pin` as method receivers][56805]. | |
| 771 | ||
| 772 | Compiler | |
| 773 | -------- | |
| 774 | - [You can now set a linker flavor for `rustc` with the `-Clinker-flavor` | |
| 775 | command line argument.][56351] | |
| 416331ca | 776 | - [The minimum required LLVM version has been bumped to 6.0.][56642] |
| 0731742a XL |
777 | - [Added support for the PowerPC64 architecture on FreeBSD.][57615] |
| 778 | - [The `x86_64-fortanix-unknown-sgx` target support has been upgraded to | |
| 779 | tier 2 support.][57130] Visit the [platform support][platform-support] page for | |
| 780 | information on Rust's platform support. | |
| 781 | - [Added support for the `thumbv7neon-linux-androideabi` and | |
| 782 | `thumbv7neon-unknown-linux-gnueabihf` targets.][56947] | |
| 783 | - [Added support for the `x86_64-unknown-uefi` target.][56769] | |
| 784 | ||
| 785 | Libraries | |
| 786 | --------- | |
| 787 | - [The methods `overflowing_{add, sub, mul, shl, shr}` are now `const` | |
| 788 | functions for all numeric types.][57566] | |
| 789 | - [The methods `rotate_left`, `rotate_right`, and `wrapping_{add, sub, mul, shl, shr}` | |
| 790 | are now `const` functions for all numeric types.][57105] | |

| 792 | all signed numeric types.][57105] | |
| 793 | - [The `get` method for all `NonZero` types is now `const`.][57167] | |

873 | Version 1.32.0 (2019-01-17) |
| 874 | ========================== | |
| 875 | ||
| 876 | Language | |
| 877 | -------- | |
| 878 | #### 2018 edition | |
| 879 | - [You can now use the `?` operator in macro definitions.][56245] The `?` | |
| 880 | operator allows you to specify zero or one repetitions similar to the `*` and | |
| 881 | `+` operators. | |
| 882 | - [Module paths with no leading keyword like `super`, `self`, or `crate`, will | |
| 883 | now always resolve to the item (`enum`, `struct`, etc.) available in the | |
| 884 | module if present, before resolving to a external crate or an item the prelude.][56759] | |
| 885 | E.g. | |
| 886 | ```rust | |
| 887 | enum Color { Red, Green, Blue } | |
| 888 | ||
| 889 | use Color::*; | |
| 890 | ``` | |
| 891 | ||
| 892 | #### All editions | |
| 893 | - [You can now match against `PhantomData<T>` types.][55837] | |
| 894 | - [You can now match against literals in macros with the `literal` | |
| 895 | specifier.][56072] This will match against a literal of any type. | |
| 896 | E.g. `1`, `'A'`, `"Hello World"` | |
| 0731742a | 897 | - [Self can now be used as a constructor and pattern for unit and tuple structs.][56365] E.g. |
| 69743fb6 XL |
898 | ```rust |
| 899 | struct Point(i32, i32); | |
| 900 | ||
| 901 | impl Point { | |
| 902 | pub fn new(x: i32, y: i32) -> Self { | |
| 903 | Self(x, y) | |
| 904 | } | |
| 905 | ||
| 906 | pub fn is_origin(&self) -> bool { | |
| 907 | match self { | |
| 908 | Self(0, 0) => true, | |
| 909 | _ => false, | |
| 910 | } | |
| 911 | } | |
| 912 | } | |
| 913 | ``` | |
| 914 | - [Self can also now be used in type definitions.][56366] E.g. | |
| 915 | ```rust | |
| 916 | enum List<T> | |
| 917 | where | |
| 918 | Self: PartialOrd<Self> // can write `Self` instead of `List<T>` | |
| 919 | { | |
| 920 | Nil, | |
| 921 | Cons(T, Box<Self>) // likewise here | |
| 922 | } | |
| 923 | ``` | |
| 924 | - [You can now mark traits with `#[must_use]`.][55663] This provides a warning if | |
| 925 | a `impl Trait` or `dyn Trait` is returned and unused in the program. | |
| 926 | ||
| 927 | Compiler | |
| 928 | -------- | |
| 929 | - [The default allocator has changed from jemalloc to the default allocator on | |
| 930 | your system.][55238] The compiler itself on Linux & macOS will still use | |
| 931 | jemalloc, but programs compiled with it will use the system allocator. | |
| 932 | - [Added the `aarch64-pc-windows-msvc` target.][55702] | |
| 933 | ||
| 934 | Libraries | |
| 935 | --------- | |
| 936 | - [`PathBuf` now implements `FromStr`.][55148] | |
| 937 | - [`Box<[T]>` now implements `FromIterator<T>`.][55843] | |
| 938 | - [The `dbg!` macro has been stabilized.][56395] This macro enables you to | |
| 939 | easily debug expressions in your rust program. E.g. | |
| 940 | ```rust | |
| 941 | let a = 2; | |
| 942 | let b = dbg!(a * 2) + 1; | |
| 943 | // ^-- prints: [src/main.rs:4] a * 2 = 4 | |
| 944 | assert_eq!(b, 5); | |
| 945 | ``` | |
| 946 | ||
| 947 | The following APIs are now `const` functions and can be used in a | |
| 948 | `const` context. | |

1267 | Version 1.30.0 (2018-10-25) |
| 1268 | ========================== | |
| 1269 | ||
| 1270 | Language | |
| 1271 | -------- | |
| 1272 | - [Procedural macros are now available.][52081] These kinds of macros allow for | |
| 1273 | more powerful code generation. There is a [new chapter available][proc-macros] | |
| 1274 | in the Rust Programming Language book that goes further in depth. | |
| 1275 | - [You can now use keywords as identifiers using the raw identifiers | |
| 1276 | syntax (`r#`),][53236] e.g. `let r#for = true;` | |
| 1277 | - [Using anonymous parameters in traits is now deprecated with a warning and | |
| 1278 | will be a hard error in the 2018 edition.][53272] | |
| 1279 | - [You can now use `crate` in paths.][54404] This allows you to refer to the | |
| 1280 | crate root in the path, e.g. `use crate::foo;` refers to `foo` in `src/lib.rs`. | |
| 1281 | - [Using a external crate no longer requires being prefixed with `::`.][54404] | |
| 1282 | Previously, using a external crate in a module without a use statement | |
| 1283 | required `let json = ::serde_json::from_str(foo);` but can now be written | |
| 1284 | as `let json = serde_json::from_str(foo);`. | |
| 1285 | - [You can now apply the `#[used]` attribute to static items to prevent the | |
| 1286 | compiler from optimising them away, even if they appear to be unused,][51363] | |
| 1287 | e.g. `#[used] static FOO: u32 = 1;` | |
| 1288 | - [You can now import and reexport macros from other crates with the `use` | |
| 1289 | syntax.][50911] Macros exported with `#[macro_export]` are now placed into | |
| 1290 | the root module of the crate. If your macro relies on calling other local | |
| 1291 | macros, it is recommended to export with the | |
| 1292 | `#[macro_export(local_inner_macros)]` attribute so users won't have to import | |
| 1293 | those macros. | |
| 1294 | - [You can now catch visibility keywords (e.g. `pub`, `pub(crate)`) in macros | |
| 1295 | using the `vis` specifier.][53370] | |
| 1296 | - [Non-macro attributes now allow all forms of literals, not just | |
| 1297 | strings.][53044] Previously, you would write `#[attr("true")]`, and you can now | |
| 1298 | write `#[attr(true)]`. | |
| 1299 | - [You can now specify a function to handle a panic in the Rust runtime with the | |
| 1300 | `#[panic_handler]` attribute.][51366] | |
| 1301 | ||
| 1302 | Compiler | |
| 1303 | -------- | |
| 1304 | - [Added the `riscv32imc-unknown-none-elf` target.][53822] | |
| 1305 | - [Added the `aarch64-unknown-netbsd` target][53165] | |
| 1306 | ||
| 1307 | Libraries | |
| 1308 | --------- | |
| 1309 | - [`ManuallyDrop` now allows the inner type to be unsized.][53033] | |

| 1342 | debug symbols.][53774] | |
| 1343 | - [Attributes from Rust tools such as `rustfmt` or `clippy` are now | |
| 1344 | available,][53459] e.g. `#[rustfmt::skip]` will skip formatting the next item. | |

| 1393 | Security Notes | |
| 1394 | -------------- | |
| 1395 | ||
| 1396 | - The standard library's `str::repeat` function contained an out of bounds write | |

1489 | =========================== |
| 1490 | ||
| 94b46f34 XL |
1491 | Language |
| 1492 | -------- | |
| 1493 | - [The `#[repr(transparent)]` attribute is now stable.][51562] This attribute | |
| 1494 | allows a Rust newtype wrapper (`struct NewType<T>(T);`) to be represented as | |
| 1495 | the inner type across Foreign Function Interface (FFI) boundaries. | |
| 1496 | - [The keywords `pure`, `sizeof`, `alignof`, and `offsetof` have been unreserved | |
| 1497 | and can now be used as identifiers.][51196] | |
| 1498 | - [The `GlobalAlloc` trait and `#[global_allocator]` attribute are now | |
| 1499 | stable.][51241] This will allow users to specify a global allocator for | |
| 1500 | their program. | |
| 1501 | - [Unit test functions marked with the `#[test]` attribute can now return | |
| 1502 | `Result<(), E: Debug>` in addition to `()`.][51298] | |
| 1503 | - [The `lifetime` specifier for `macro_rules!` is now stable.][50385] This | |
| 1504 | allows macros to easily target lifetimes. | |
| 1505 | ||
| 1506 | Compiler | |
| 1507 | -------- | |
| 1508 | - [The `s` and `z` optimisation levels are now stable.][50265] These optimisations | |
| 1509 | prioritise making smaller binary sizes. `z` is the same as `s` with the | |
| 1510 | exception that it does not vectorise loops, which typically results in an even | |
| 1511 | smaller binary. | |
| 1512 | - [The short error format is now stable.][49546] Specified with | |
| 1513 | `--error-format=short` this option will provide a more compressed output of | |
| 1514 | rust error messages. | |
| 1515 | - [Added a lint warning when you have duplicated `macro_export`s.][50143] | |
| 1516 | - [Reduced the number of allocations in the macro parser.][50855] This can | |
| 1517 | improve compile times of macro heavy crates on average by 5%. | |
| 1518 | ||
| 1519 | Libraries | |
| 1520 | --------- | |
| 1521 | - [Implemented `Default` for `&mut str`.][51306] | |
| 1522 | - [Implemented `From<bool>` for all integer and unsigned number types.][50554] | |
| 1523 | - [Implemented `Extend` for `()`.][50234] | |
| 1524 | - [The `Debug` implementation of `time::Duration` should now be more easily | |
| 1525 | human readable.][50364] Previously a `Duration` of one second would printed as | |
| 1526 | `Duration { secs: 1, nanos: 0 }` and will now be printed as `1s`. | |
| 1527 | - [Implemented `From<&String>` for `Cow<str>`, `From<&Vec<T>>` for `Cow<[T]>`, | |
| 1528 | `From<Cow<CStr>>` for `CString`, `From<CString>, From<CStr>, From<&CString>` | |
| 1529 | for `Cow<CStr>`, `From<OsString>, From<OsStr>, From<&OsString>` for | |
| 1530 | `Cow<OsStr>`, `From<&PathBuf>` for `Cow<Path>`, and `From<Cow<Path>>` | |
| 1531 | for `PathBuf`.][50170] | |
| 1532 | - [Implemented `Shl` and `Shr` for `Wrapping<u128>` | |
| 1533 | and `Wrapping<i128>`.][50465] | |
| 1534 | - [`DirEntry::metadata` now uses `fstatat` instead of `lstat` when | |
| 1535 | possible.][51050] This can provide up to a 40% speed increase. | |
| 1536 | - [Improved error messages when using `format!`.][50610] | |

| 1571 | ----- | |
| 1572 | - [Cargo will now no longer allow you to publish crates with build scripts that | |
| 1573 | modify the `src` directory.][cargo/5584] The `src` directory in a crate should be | |
| 1574 | considered to be immutable. | |
| 1575 | ||
| 1576 | Misc | |
| 1577 | ---- | |
| 1578 | - [The `suggestion_applicability` field in `rustc`'s json output is now | |
| 1579 | stable.][50486] This will allow dev tools to check whether a code suggestion | |
| 1580 | would apply to them. | |

| 1686 | ========================== | |
| 1687 | ||
| 1688 | Language | |
| 1689 | -------- | |
| 1690 | - [Removed 'proc' from the reserved keywords list.][49699] This allows `proc` to | |
| 8faf50e0 | 1691 | be used as an identifier. |
| 83c7162d XL |
1692 | - [The dyn syntax is now available.][49968] This syntax is equivalent to the |
| 1693 | bare `Trait` syntax, and should make it clearer when being used in tandem with | |
| 4462d4a0 | 1694 | `impl Trait` because it is equivalent to the following syntax: |
| 83c7162d XL |
1695 | `&Trait == &dyn Trait`, `&mut Trait == &mut dyn Trait`, and |
| 1696 | `Box<Trait> == Box<dyn Trait>`. | |
| 1697 | - [Attributes on generic parameters such as types and lifetimes are | |
| 1698 | now stable.][48851] e.g. | |
| 1699 | `fn foo<#[lifetime_attr] 'a, #[type_attr] T: 'a>() {}` | |
| 1700 | - [The `#[must_use]` attribute can now also be used on functions as well as | |
| 1701 | types.][48925] It provides a lint that by default warns users when the | |
| 1702 | value returned by a function has not been used. | |
| 1703 | ||
| 1704 | Compiler | |
| 1705 | -------- | |
| b7449926 | 1706 | - [Added the `armv5te-unknown-linux-musleabi` target.][50423] |

1707 | |
| 1708 | Libraries | |
| 1709 | --------- | |
| 1710 | - [SIMD (Single Instruction Multiple Data) on x86/x86_64 is now stable.][49664] | |
| 1711 | This includes [`arch::x86`] & [`arch::x86_64`] modules which contain | |
| 1712 | SIMD intrinsics, a new macro called `is_x86_feature_detected!`, the | |
| 1713 | `#[target_feature(enable="")]` attribute, and adding `target_feature = ""` to | |
| 1714 | the `cfg` attribute. | |
| 1715 | - [A lot of methods for `[u8]`, `f32`, and `f64` previously only available in | |
| 1716 | std are now available in core.][49896] | |
| 1717 | - [The generic `Rhs` type parameter on `ops::{Shl, ShlAssign, Shr}` now defaults | |
| 1718 | to `Self`.][49630] | |
| 1719 | - [`std::str::replace` now has the `#[must_use]` attribute][50177] to clarify | |
| 1720 | that the operation isn't done in place. | |
| 1721 | - [`Clone::clone`, `Iterator::collect`, and `ToOwned::to_owned` now have | |
| 1722 | the `#[must_use]` attribute][49533] to warn about unused potentially | |
| 1723 | expensive allocations. | |

| 1749 | ----- | |
| 1750 | - [`cargo-metadata` now includes `authors`, `categories`, `keywords`, | |
| 1751 | `readme`, and `repository` fields.][cargo/5386] | |
| 94b46f34 | 1752 | - [`cargo-metadata` now includes a package's `metadata` table.][cargo/5360] |
| 83c7162d XL |
1753 | - [Added the `--target-dir` optional argument.][cargo/5393] This allows you to specify |
| 1754 | a different directory than `target` for placing compilation artifacts. | |
| 1755 | - [Cargo will be adding automatic target inference for binaries, benchmarks, | |
| 1756 | examples, and tests in the Rust 2018 edition.][cargo/5335] If your project specifies | |
| 4462d4a0 | 1757 | specific targets, e.g. using `[[bin]]`, and have other binaries in locations |
| 83c7162d | 1758 | where cargo would infer a binary, Cargo will produce a warning. You can |
| 4462d4a0 XL |
1759 | disable this feature ahead of time by setting any of the following to false: |
| 1760 | `autobins`, `autobenches`, `autoexamples`, `autotests`. | |
| 83c7162d XL |
1761 | - [Cargo will now cache compiler information.][cargo/5359] This can be disabled by |
| 1762 | setting `CARGO_CACHE_RUSTC_INFO=0` in your environment. | |
| 1763 | ||
| 1764 | Misc | |
| 1765 | ---- | |
| 1766 | - [Added “The Rustc book” into the official documentation.][49707] | |
| 1767 | [“The Rustc book”] documents and teaches how to use the rustc compiler. | |
| 1768 | - [All books available on `doc.rust-lang.org` are now searchable.][49623] | |
| 1769 | ||
| 1770 | Compatibility Notes | |
| 1771 | ------------------- | |
| 1772 | - [Calling a `CharExt` or `StrExt` method directly on core will no longer | |
| 1773 | work.][49896] e.g. `::core::prelude::v1::StrExt::is_empty("")` will not | |
| 1774 | compile, `"".is_empty()` will still compile. | |
| 1775 | - [`Debug` output on `atomic::{AtomicBool, AtomicIsize, AtomicPtr, AtomicUsize}` | |
| 4462d4a0 XL |
1776 | will only print the inner type.][48553] E.g. |
| 1777 | `print!("{:?}", AtomicBool::new(true))` will print `true`, | |
| 83c7162d XL |
1778 | not `AtomicBool(true)`. |
| 1779 | - [The maximum number for `repr(align(N))` is now 2²⁹.][50378] Previously you | |
| 1780 | could enter higher numbers but they were not supported by LLVM. Up to 512MB | |
| 1781 | alignment should cover all use cases. | |
| b7449926 XL |
1782 | - The `.description()` method on the `std::error::Error` trait |
| 1783 | [has been soft-deprecated][50163]. It is no longer required to implement it. | |

| 1871 | ========================== | |
| 1872 | ||
| 1873 | Language | |
| 1874 | -------- | |
| 1875 | - [Closures now implement `Copy` and/or `Clone` if all captured variables | |
| 1876 | implement either or both traits.][49299] | |
| 1877 | - [The inclusive range syntax e.g. `for x in 0..=10` is now stable.][47813] | |
| 4462d4a0 | 1878 | - [The `'_` lifetime is now stable. The underscore lifetime can be used anywhere a |
| 564c78a2 XL |
1879 | lifetime can be elided.][49458] |
| 1880 | - [`impl Trait` is now stable allowing you to have abstract types in returns | |
| 4462d4a0 | 1881 | or in function parameters.][49255] E.g. `fn foo() -> impl Iterator<Item=u8>` or |
| 564c78a2 XL |
1882 | `fn open(path: impl AsRef<Path>)`. |
| 1883 | - [Pattern matching will now automatically apply dereferences.][49394] | |
| 1884 | - [128-bit integers in the form of `u128` and `i128` are now stable.][49101] | |
| 1885 | - [`main` can now return `Result<(), E: Debug>`][49162] in addition to `()`. | |
| 1886 | - [A lot of operations are now available in a const context.][46882] E.g. You | |
| 1887 | can now index into constant arrays, reference and dereference into constants, | |
| 4462d4a0 XL |
1888 | and use tuple struct constructors. |
| 1889 | - [Fixed entry slice patterns are now stable.][48516] E.g. | |
| 564c78a2 XL |
1890 | ```rust |
| 1891 | let points = [1, 2, 3, 4]; | |
| 1892 | match points { | |
| 1893 | [1, 2, 3, 4] => println!("All points were sequential."), | |
| 1894 | _ => println!("Not all points were sequential."), | |
| 1895 | } | |
| 1896 | ``` | |
| 1897 | ||
| 1898 | ||
| 1899 | Compiler | |
| 1900 | -------- | |
| 1901 | - [LLD is now used as the default linker for `wasm32-unknown-unknown`.][48125] | |
| 1902 | - [Fixed exponential projection complexity on nested types.][48296] | |
| 1903 | This can provide up to a ~12% reduction in compile times for certain crates. | |
| 1904 | - [Added the `--remap-path-prefix` option to rustc.][48359] Allowing you | |
| 1905 | to remap path prefixes outputted by the compiler. | |
| 1906 | - [Added `powerpc-unknown-netbsd` target.][48281] | |
| 1907 | ||
| 1908 | Libraries | |
| 1909 | --------- | |
| 1910 | - [Implemented `From<u16> for usize` & `From<{u8, i16}> for isize`.][49305] | |
| 1911 | - [Added hexadecimal formatting for integers with fmt::Debug][48978] | |
| 1912 | e.g. `assert!(format!("{:02x?}", b"Foo\0") == "[46, 6f, 6f, 00]")` | |
| 1913 | - [Implemented `Default, Hash` for `cmp::Reverse`.][48628] | |
| 1914 | - [Optimized `str::repeat` being 8x faster in large cases.][48657] | |
| 1915 | - [`ascii::escape_default` is now available in libcore.][48735] | |
| 1916 | - [Trailing commas are now supported in std and core macros.][48056] | |
| 1917 | - [Implemented `Copy, Clone` for `cmp::Reverse`][47379] | |
| 1918 | - [Implemented `Clone` for `char::{ToLowercase, ToUppercase}`.][48629] | |

| 1976 | ------------------- | |
| 1977 | ||
| 1978 | - [aliasing a `Fn` trait as `dyn` no longer works.][48481] E.g. the following | |
| 1979 | syntax is now invalid. | |
| 1980 | ``` | |
| 1981 | use std::ops::Fn as dyn; | |
| 1982 | fn g(_: Box<dyn(std::fmt::Debug)>) {} | |
| 1983 | ``` | |
| 1984 | - [The result of dereferences are no longer promoted to `'static`.][47408] | |
| 1985 | e.g. | |
| 1986 | ```rust | |
| 1987 | fn main() { | |
| 1988 | const PAIR: &(i32, i32) = &(0, 1); | |
| 1989 | let _reversed_pair: &'static _ = &(PAIR.1, PAIR.0); // Doesn't work | |

| 2673 | ----- | |
| 2674 | - [Cargo API token location moved from `~/.cargo/config` to | |
| 2675 | `~/.cargo/credentials`.][cargo/3978] | |
| 2676 | - [Cargo will now build `main.rs` binaries that are in sub-directories of | |
| 2677 | `src/bin`.][cargo/4214] ie. Having `src/bin/server/main.rs` and | |
| 2678 | `src/bin/client/main.rs` generates `target/debug/server` and `target/debug/client` | |
| 2679 | - [You can now specify version of a binary when installed through | |
| 2680 | `cargo install` using `--vers`.][cargo/4229] | |
| 2681 | - [Added `--no-fail-fast` flag to cargo to run all benchmarks regardless of | |
| 2682 | failure.][cargo/4248] | |
| 2683 | - [Changed the convention around which file is the crate root.][cargo/4259] | |
| 2684 | - [The `include`/`exclude` property in `Cargo.toml` now accepts gitignore paths | |
| 2685 | instead of glob patterns][cargo/4270]. Glob patterns are now deprecated. | |
| 2686 | ||
| 2687 | Compatibility Notes | |
| 2688 | ------------------- | |
| 2689 | ||
| 2690 | - [Functions with `'static` in their return types will now not be as usable as | |
| 2691 | if they were using lifetime parameters instead.][42417] | |
| 2692 | - [The reimplementation of `{f32, f64}::is_sign_{negative, positive}` now | |
| ea8adc8c | 2693 | takes the sign of NaN into account where previously didn't.][42430] |

| 2764 | Version 1.19.0 (2017-07-20) | |
| 2765 | =========================== | |
| 2766 | ||
| 2767 | Language | |
| 2768 | -------- | |
| 2769 | ||
| 2770 | - [Numeric fields can now be used for creating tuple structs.][41145] [RFC 1506] | |
| 2771 | For example `struct Point(u32, u32); let x = Point { 0: 7, 1: 0 };`. | |
| 2772 | - [Macro recursion limit increased to 1024 from 64.][41676] | |
| 2773 | - [Added lint for detecting unused macros.][41907] | |
| 2774 | - [`loop` can now return a value with `break`.][42016] [RFC 1624] | |
| 2775 | For example: `let x = loop { break 7; };` | |
| 2776 | - [C compatible `union`s are now available.][42068] [RFC 1444] They can only | |
| 2777 | contain `Copy` types and cannot have a `Drop` implementation. | |
| 2778 | Example: `union Foo { bar: u8, baz: usize }` | |
| 2779 | - [Non capturing closures can now be coerced into `fn`s,][42162] [RFC 1558] | |
| 2780 | Example: `let foo: fn(u8) -> u8 = |v: u8| { v };` | |
| 2781 | ||
| 2782 | Compiler | |
| 2783 | -------- | |
| 2784 | ||
| 2785 | - [Add support for bootstrapping the Rust compiler toolchain on Android.][41370] | |
| 2786 | - [Change `arm-linux-androideabi` to correspond to the `armeabi` | |
| 2787 | official ABI.][41656] If you wish to continue targeting the `armeabi-v7a` ABI | |
| 2788 | you should use `--target armv7-linux-androideabi`. | |
| 2789 | - [Fixed ICE when removing a source file between compilation sessions.][41873] | |
| 2790 | - [Minor optimisation of string operations.][42037] | |
| 2791 | - [Compiler error message is now `aborting due to previous error(s)` instead of | |
| 2792 | `aborting due to N previous errors`][42150] This was previously inaccurate and | |
| 2793 | would only count certain kinds of errors. | |
| 2794 | - [The compiler now supports Visual Studio 2017][42225] | |
| 2795 | - [The compiler is now built against LLVM 4.0.1 by default][42948] | |
| 2796 | - [Added a lot][42264] of [new error codes][42302] | |
| 2797 | - [Added `target-feature=+crt-static` option][37406] [RFC 1721] Which allows | |
| 2798 | libraries with C Run-time Libraries(CRT) to be statically linked. | |
| 2799 | - [Fixed various ARM codegen bugs][42740] | |
| 2800 | ||
| 2801 | Libraries | |
| 2802 | --------- | |
| 2803 | ||
| 2804 | - [`String` now implements `FromIterator<Cow<'a, str>>` and | |
| 2805 | `Extend<Cow<'a, str>>`][41449] | |
| 2806 | - [`Vec` now implements `From<&mut [T]>`][41530] | |
| 2807 | - [`Box<[u8]>` now implements `From<Box<str>>`][41258] | |
| 2808 | - [`SplitWhitespace` now implements `Clone`][41659] | |
| 2809 | - [`[u8]::reverse` is now 5x faster and `[u16]::reverse` is now | |
| 2810 | 1.5x faster][41764] | |
| 2811 | - [`eprint!` and `eprintln!` macros added to prelude.][41192] Same as the `print!` | |
| 2812 | macros, but for printing to stderr. | |
| 2813 | ||
| 2814 | Stabilized APIs | |
| 2815 | --------------- | |
| 2816 | ||
| 2817 | - [`OsString::shrink_to_fit`] | |
| 2818 | - [`cmp::Reverse`] | |
| 2819 | - [`Command::envs`] | |
| 2820 | - [`thread::ThreadId`] | |
| 2821 | ||
| 2822 | Cargo | |
| 2823 | ----- | |
| 2824 | ||
| 2825 | - [Build scripts can now add environment variables to the environment | |
| 2826 | the crate is being compiled in. | |
| 2827 | Example: `println!("cargo:rustc-env=FOO=bar");`][cargo/3929] | |
| 2828 | - [Subcommands now replace the current process rather than spawning a new | |
| 2829 | child process][cargo/3970] | |
| 2830 | - [Workspace members can now accept glob file patterns][cargo/3979] | |
| 2831 | - [Added `--all` flag to the `cargo bench` subcommand to run benchmarks of all | |
| 2832 | the members in a given workspace.][cargo/3988] | |
| 2833 | - [Updated `libssh2-sys` to 0.2.6][cargo/4008] | |
| 2834 | - [Target directory path is now in the cargo metadata][cargo/4022] | |
| 2835 | - [Cargo no longer checks out a local working directory for the | |
| 2836 | crates.io index][cargo/4026] This should provide smaller file size for the | |
| 2837 | registry, and improve cloning times, especially on Windows machines. | |
| 2838 | - [Added an `--exclude` option for excluding certain packages when using the | |
| 2839 | `--all` option][cargo/4031] | |
| 2840 | - [Cargo will now automatically retry when receiving a 5xx error | |
| 2841 | from crates.io][cargo/4032] | |
| 2842 | - [The `--features` option now accepts multiple comma or space | |
| 2843 | delimited values.][cargo/4084] | |
| 2844 | - [Added support for custom target specific runners][cargo/3954] | |
| 2845 | ||
| 2846 | Misc | |
| 2847 | ---- | |
| 2848 | ||
| 2849 | - [Added `rust-windbg.cmd`][39983] for loading rust `.natvis` files in the | |
| 2850 | Windows Debugger. | |
| 2851 | - [Rust will now release XZ compressed packages][rust-installer/57] | |
| 2852 | - [rustup will now prefer to download rust packages with | |
| 2853 | XZ compression][rustup/1100] over GZip packages. | |
| 2854 | - [Added the ability to escape `#` in rust documentation][41785] By adding | |
| 2855 | additional `#`'s ie. `##` is now `#` | |
| 2856 | ||
| 2857 | Compatibility Notes | |
| 2858 | ------------------- | |
| 2859 | ||
| 2860 | - [`MutexGuard<T>` may only be `Sync` if `T` is `Sync`.][41624] | |
| 2861 | - [`-Z` flags are now no longer allowed to be used on the stable | |
| 2862 | compiler.][41751] This has been a warning for a year previous to this. | |
| 2863 | - [As a result of the `-Z` flag change, the `cargo-check` plugin no | |
| 2864 | longer works][42844]. Users should migrate to the built-in `check` | |
| 2865 | command, which has been available since 1.16. | |
| 2866 | - [Ending a float literal with `._` is now a hard error. | |
| 2867 | Example: `42._` .][41946] | |
| 2868 | - [Any use of a private `extern crate` outside of its module is now a | |
| 2869 | hard error.][36886] This was previously a warning. | |
| 2870 | - [`use ::self::foo;` is now a hard error.][36888] `self` paths are always | |
| 2871 | relative while the `::` prefix makes a path absolute, but was ignored and the | |
| 2872 | path was relative regardless. | |
| 2873 | - [Floating point constants in match patterns is now a hard error][36890] | |
| 2874 | This was previously a warning. | |
| 2875 | - [Struct or enum constants that don't derive `PartialEq` & `Eq` used | |
| 2876 | match patterns is now a hard error][36891] This was previously a warning. | |
| 2877 | - [Lifetimes named `'_` are no longer allowed.][36892] This was previously | |
| 2878 | a warning. | |
| 2879 | - [From the pound escape, lines consisting of multiple `#`s are | |
| 2880 | now visible][41785] | |
| 2c00a5a8 | 2881 | - [It is an error to re-export private enum variants][42460]. This is |
| 3b2f2976 XL |
2882 | known to break a number of crates that depend on an older version of |
| 2883 | mustache. | |
| 2884 | - [On Windows, if `VCINSTALLDIR` is set incorrectly, `rustc` will try | |
| 2885 | to use it to find the linker, and the build will fail where it did | |
| 2886 | not previously][42607] | |

2948 | Version 1.18.0 (2017-06-08) |
| 2949 | =========================== | |
| 2950 | ||
| 2951 | Language | |
| 2952 | -------- | |
| 2953 | ||
| 2954 | - [Stabilize pub(restricted)][40556] `pub` can now accept a module path to | |
| 2955 | make the item visible to just that module tree. Also accepts the keyword | |
| 2956 | `crate` to make something public to the whole crate but not users of the | |
| 2957 | library. Example: `pub(crate) mod utils;`. [RFC 1422]. | |
| 2958 | - [Stabilize `#![windows_subsystem]` attribute][40870] conservative exposure of the | |
| 2959 | `/SUBSYSTEM` linker flag on Windows platforms. [RFC 1665]. | |
| 2960 | - [Refactor of trait object type parsing][40043] Now `ty` in macros can accept | |
| 2961 | types like `Write + Send`, trailing `+` are now supported in trait objects, | |
| 2962 | and better error reporting for trait objects starting with `?Sized`. | |
| 2963 | - [0e+10 is now a valid floating point literal][40589] | |
| 2964 | - [Now warns if you bind a lifetime parameter to 'static][40734] | |
| 2965 | - [Tuples, Enum variant fields, and structs with no `repr` attribute or with | |
| 2966 | `#[repr(Rust)]` are reordered to minimize padding and produce a smaller | |
| 2967 | representation in some cases.][40377] | |
| 2968 | ||
| 2969 | Compiler | |
| 2970 | -------- | |
| 2971 | ||
| 2972 | - [rustc can now emit mir with `--emit mir`][39891] | |
| 2973 | - [Improved LLVM IR for trivial functions][40367] | |
| 2974 | - [Added explanation for E0090(Wrong number of lifetimes are supplied)][40723] | |
| 2975 | - [rustc compilation is now 15%-20% faster][41469] Thanks to optimisation | |
| 2976 | opportunities found through profiling | |
| 2977 | - [Improved backtrace formatting when panicking][38165] | |
| 2978 | ||
| 2979 | Libraries | |
| 2980 | --------- | |
| 2981 | ||
| 2982 | - [Specialized `Vec::from_iter` being passed `vec::IntoIter`][40731] if the | |
| 2983 | iterator hasn't been advanced the original `Vec` is reassembled with no actual | |
| 2984 | iteration or reallocation. | |
| 2985 | - [Simplified HashMap Bucket interface][40561] provides performance | |
| 2986 | improvements for iterating and cloning. | |
| 2987 | - [Specialize Vec::from_elem to use calloc][40409] | |
| 2988 | - [Fixed Race condition in fs::create_dir_all][39799] | |
| 2989 | - [No longer caching stdio on Windows][40516] | |
| 2990 | - [Optimized insertion sort in slice][40807] insertion sort in some cases | |
| 2991 | 2.50%~ faster and in one case now 12.50% faster. | |
| 2992 | - [Optimized `AtomicBool::fetch_nand`][41143] | |
| 2993 | ||
| 2994 | Stabilized APIs | |
| 2995 | --------------- | |
| 2996 | ||
| 2997 | - [`Child::try_wait`] | |

| 3005 | Cargo | |
| 3006 | ----- | |
| 3007 | ||
| 3008 | - [Added partial Pijul support][cargo/3842] Pijul is a version control system in Rust. | |
| 3009 | You can now create new cargo projects with Pijul using `cargo new --vcs pijul` | |
| 3010 | - [Now always emits build script warnings for crates that fail to build][cargo/3847] | |
| 3011 | - [Added Android build support][cargo/3885] | |
| 3012 | - [Added `--bins` and `--tests` flags][cargo/3901] now you can build all programs | |
| 3013 | of a certain type, for example `cargo build --bins` will build all | |
| 3014 | binaries. | |
| 3015 | - [Added support for haiku][cargo/3952] | |
| 3016 | ||
| 3017 | Misc | |
| 3018 | ---- | |

| ff7c6d11 | 3021 | - [Added rust-windbg script for better debugging on Windows][39983] |
| cc61c64b XL |
3022 | - [Rust now uses the official cross compiler for NetBSD][40612] |
| 3023 | - [rustdoc now accepts `#` at the start of files][40828] | |
| 3024 | - [Fixed jemalloc support for musl][41168] | |
| 3025 | ||
| 3026 | Compatibility Notes | |
| 3027 | ------------------- | |
| 3028 | ||
| 3029 | - [Changes to how the `0` flag works in format!][40241] Padding zeroes are now | |
| 3030 | always placed after the sign if it exists and before the digits. With the `#` | |
| 3031 | flag the zeroes are placed after the prefix and before the digits. | |
| 3032 | - [Due to the struct field optimisation][40377], using `transmute` on structs | |
| 3033 | that have no `repr` attribute or `#[repr(Rust)]` will no longer work. This has | |
| 3034 | always been undefined behavior, but is now more likely to break in practice. | |
| 3035 | - [The refactor of trait object type parsing][40043] fixed a bug where `+` was | |
| 3036 | receiving the wrong priority parsing things like `&for<'a> Tr<'a> + Send` as | |
| 3037 | `&(for<'a> Tr<'a> + Send)` instead of `(&for<'a> Tr<'a>) + Send` | |
| 3038 | - [Overlapping inherent `impl`s are now a hard error][40728] | |
| 3039 | - [`PartialOrd` and `Ord` must agree on the ordering.][41270] | |
| 3040 | - [`rustc main.rs -o out --emit=asm,llvm-ir`][41085] Now will output | |
| 3041 | `out.asm` and `out.ll` instead of only one of the filetypes. | |
| 3042 | - [ calling a function that returns `Self` will no longer work][41805] when | |
| 3043 | the size of `Self` cannot be statically determined. | |
| 3044 | - [rustc now builds with a "pthreads" flavour of MinGW for Windows GNU][40805] | |
| 3045 | this has caused a few regressions namely: | |
| 3046 | ||
| 3047 | - Changed the link order of local static/dynamic libraries (respecting the | |
| 3048 | order on given rather than having the compiler reorder). | |
| 3049 | - Changed how MinGW is linked, native code linked to dynamic libraries | |
| 3050 | may require manually linking to the gcc support library (for the native | |
| 3051 | code itself) | |

| 3099 | =========================== | |
| 3100 | ||
| 3101 | Language | |
| 3102 | -------- | |
| 3103 | ||
| 3104 | * [The lifetime of statics and consts defaults to `'static`][39265]. [RFC 1623] | |
| 3105 | * [Fields of structs may be initialized without duplicating the field/variable | |
| 3106 | names][39761]. [RFC 1682] | |
| 3107 | * [`Self` may be included in the `where` clause of `impls`][38864]. [RFC 1647] | |
| 3108 | * [When coercing to an unsized type lifetimes must be equal][40319]. That is, | |
| 3109 | there is no subtyping between `T` and `U` when `T: Unsize<U>`. For example, | |
| 3110 | coercing `&mut [&'a X; N]` to `&mut [&'b X]` requires `'a` be equal to | |
| 3111 | `'b`. Soundness fix. | |
| 3112 | * [Values passed to the indexing operator, `[]`, automatically coerce][40166] | |
| 3113 | * [Static variables may contain references to other statics][40027] | |
| 3114 | ||
| 3115 | Compiler | |
| 3116 | -------- | |
| 3117 | ||
| 3118 | * [Exit quickly on only `--emit dep-info`][40336] | |
| 3119 | * [Make `-C relocation-model` more correctly determine whether the linker | |
| 3120 | creates a position-independent executable][40245] | |
| 3121 | * [Add `-C overflow-checks` to directly control whether integer overflow | |
| 3122 | panics][40037] | |
| 3123 | * [The rustc type checker now checks items on demand instead of in a single | |
| 3124 | in-order pass][40008]. This is mostly an internal refactoring in support of | |
| 3125 | future work, including incremental type checking, but also resolves [RFC | |
| 3126 | 1647], allowing `Self` to appear in `impl` `where` clauses. | |
| 3127 | * [Optimize vtable loads][39995] | |
| 3128 | * [Turn off vectorization for Emscripten targets][39990] | |
| 3129 | * [Provide suggestions for unknown macros imported with `use`][39953] | |
| 3130 | * [Fix ICEs in path resolution][39939] | |
| 3131 | * [Strip exception handling code on Emscripten when `panic=abort`][39193] | |
| 3132 | * [Add clearer error message using `&str + &str`][39116] | |

| 3240 | * [`format!` and `Display::to_string` panic if an underlying formatting | |
| 3241 | implementation returns an error][40117]. Previously the error was silently | |
| 3242 | ignored. It is incorrect for `write_fmt` to return an error when writing | |
| 3243 | to a string. | |
| 3244 | * [In-tree crates are verified to be unstable][39851]. Previously, some minor | |
| 3245 | crates were marked stable and could be accessed from the stable toolchain. | |
| 3246 | * [Rust git source no longer includes vendored crates][39728]. Those that need | |
| 3247 | to build with vendored crates should build from release tarballs. | |
| 3248 | * [Fix inert attributes from `proc_macro_derives`][39572] | |
| 3249 | * [During crate resolution, rustc prefers a crate in the sysroot if two crates | |
| 3250 | are otherwise identical][39518]. Unlikely to be encountered outside the Rust | |
| 3251 | build system. | |
| 3252 | * [Fixed bugs around how type inference interacts with dead-code][39485]. The | |
| 3253 | existing code generally ignores the type of dead-code unless a type-hint is | |
| 3254 | provided; this can cause surprising inference interactions particularly around | |
| 3255 | defaulting. The new code uniformly ignores the result type of dead-code. | |
| 3256 | * [Tuple-struct constructors with private fields are no longer visible][38932] | |
| 3257 | * [Lifetime parameters that do not appear in the arguments are now considered | |
| 3258 | early-bound][38897], resolving a soundness bug (#[32330]). The | |
| 3259 | `hr_lifetime_in_assoc_type` future-compatibility lint has been in effect since | |
| 3260 | April of 2016. | |
| 3261 | * [rustdoc: fix doctests with non-feature crate attributes][38161] | |
| 3262 | * [Make transmuting from fn item types to pointer-sized types a hard | |
| 3263 | error][34198] | |

3356 | Version 1.16.0 (2017-03-16) |
| 3357 | =========================== | |
| 3358 | ||
| 3359 | Language | |
| 3360 | -------- | |
| 3361 | ||
| 32a655c1 SL |
3362 | * [The compiler's `dead_code` lint now accounts for type aliases][38051]. |
| 3363 | * [Uninhabitable enums (those without any variants) no longer permit wildcard | |
| 3364 | match patterns][38069] | |
| 3365 | * [Clean up semantics of `self` in an import list][38313] | |
| 3366 | * [`Self` may appear in `impl` headers][38920] | |
| 3367 | * [`Self` may appear in struct expressions][39282] | |
| 3368 | ||
| 3369 | Compiler | |
| 3370 | -------- | |
| 3371 | ||
| 3372 | * [`rustc` now supports `--emit=metadata`, which causes rustc to emit | |
| 3373 | a `.rmeta` file containing only crate metadata][38571]. This can be | |
| 3374 | used by tools like the Rust Language Service to perform | |
| 3375 | metadata-only builds. | |
| 3376 | * [Levenshtein based typo suggestions now work in most places, while | |
| 3377 | previously they worked only for fields and sometimes for local | |
| 3378 | variables][38927]. Together with the overhaul of "no | |
| 3379 | resolution"/"unexpected resolution" errors (#[38154]) they result in | |
| 3380 | large and systematic improvement in resolution diagnostics. | |
| 3381 | * [Fix `transmute::<T, U>` where `T` requires a bigger alignment than | |
| 3382 | `U`][38670] | |
| 3383 | * [rustc: use -Xlinker when specifying an rpath with ',' in it][38798] | |
| 3384 | * [`rustc` no longer attempts to provide "consider using an explicit | |
| 3385 | lifetime" suggestions][37057]. They were inaccurate. | |
| 3386 | ||
| 3387 | Stabilized APIs | |
| 3388 | --------------- | |
| 3389 | ||
| 3390 | * [`VecDeque::truncate`] | |
| 3391 | * [`VecDeque::resize`] | |
| 3392 | * [`String::insert_str`] | |
| 3393 | * [`Duration::checked_add`] | |
| 3394 | * [`Duration::checked_sub`] | |
| 3395 | * [`Duration::checked_div`] | |
| 3396 | * [`Duration::checked_mul`] | |
| 3397 | * [`str::replacen`] | |
| 3398 | * [`str::repeat`] | |
| 3399 | * [`SocketAddr::is_ipv4`] | |
| 3400 | * [`SocketAddr::is_ipv6`] | |
| 3401 | * [`IpAddr::is_ipv4`] | |
| 3402 | * [`IpAddr::is_ipv6`] | |
| 3403 | * [`Vec::dedup_by`] | |
| 3404 | * [`Vec::dedup_by_key`] | |
| 3405 | * [`Result::unwrap_or_default`] | |
| 3406 | * [`<*const T>::wrapping_offset`] | |
| 3407 | * [`<*mut T>::wrapping_offset`] | |
| 3408 | * `CommandExt::creation_flags` | |
| 3409 | * [`File::set_permissions`] | |
| 3410 | * [`String::split_off`] | |
| 3411 | ||
| 3412 | Libraries | |
| 3413 | --------- | |
| 3414 | ||
| 3415 | * [`[T]::binary_search` and `[T]::binary_search_by_key` now take | |
| 3416 | their argument by `Borrow` parameter][37761] | |
| 3417 | * [All public types in std implement `Debug`][38006] | |
| 3418 | * [`IpAddr` implements `From<Ipv4Addr>` and `From<Ipv6Addr>`][38327] | |
| 3419 | * [`Ipv6Addr` implements `From<[u16; 8]>`][38131] | |
| 3420 | * [Ctrl-Z returns from `Stdin.read()` when reading from the console on | |
| 3421 | Windows][38274] | |
| 3422 | * [std: Fix partial writes in `LineWriter`][38062] | |
| 3423 | * [std: Clamp max read/write sizes on Unix][38062] | |
| 3424 | * [Use more specific panic message for `&str` slicing errors][38066] | |
| 3425 | * [`TcpListener::set_only_v6` is deprecated][38304]. This | |
| 3426 | functionality cannot be achieved in std currently. | |
| 3427 | * [`writeln!`, like `println!`, now accepts a form with no string | |
| 3428 | or formatting arguments, to just print a newline][38469] | |
| 3429 | * [Implement `iter::Sum` and `iter::Product` for `Result`][38580] | |
| 3430 | * [Reduce the size of static data in `std_unicode::tables`][38781] | |
| 3431 | * [`char::EscapeDebug`, `EscapeDefault`, `EscapeUnicode`, | |
| 3432 | `CaseMappingIter`, `ToLowercase`, `ToUppercase`, implement | |
| 3433 | `Display`][38909] | |
| 3434 | * [`Duration` implements `Sum`][38712] | |
| 3435 | * [`String` implements `ToSocketAddrs`][39048] | |
| 3436 | ||
| 3437 | Cargo | |
| 3438 | ----- | |
| 3439 | ||
| 3440 | * [The `cargo check` command does a type check of a project without | |
| 3441 | building it][cargo/3296] | |
| 3442 | * [crates.io will display CI badges from Travis and AppVeyor, if | |
| 3443 | specified in Cargo.toml][cargo/3546] | |
| 3444 | * [crates.io will display categories listed in Cargo.toml][cargo/3301] | |
| 3445 | * [Compilation profiles accept integer values for `debug`, in addition | |
| 3446 | to `true` and `false`. These are passed to `rustc` as the value to | |
| 3447 | `-C debuginfo`][cargo/3534] | |
| 3448 | * [Implement `cargo --version --verbose`][cargo/3604] | |
| 3449 | * [All builds now output 'dep-info' build dependencies compatible with | |
| 3450 | make and ninja][cargo/3557] | |
| 3451 | * [Build all workspace members with `build --all`][cargo/3511] | |
| 3452 | * [Document all workspace members with `doc --all`][cargo/3515] | |
| 3453 | * [Path deps outside workspace are not members][cargo/3443] | |
| 3454 | ||
| 3455 | Misc | |
| 3456 | ---- | |
| 3457 | ||
| 3458 | * [`rustdoc` has a `--sysroot` argument that, like `rustc`, specifies | |
| 3459 | the path to the Rust implementation][38589] | |
| 3460 | * [The `armv7-linux-androideabi` target no longer enables NEON | |
| 3461 | extensions, per Google's ABI guide][38413] | |
| 3462 | * [The stock standard library can be compiled for Redox OS][38401] | |
| 3463 | * [Rust has initial SPARC support][38726]. Tier 3. No builds | |
| 3464 | available. | |
| 3465 | * [Rust has experimental support for Nvidia PTX][38559]. Tier 3. No | |
| 3466 | builds available. | |
| 3467 | * [Fix backtraces on i686-pc-windows-gnu by disabling FPO][39379] | |
| 3468 | ||
| 3469 | Compatibility Notes | |
| 3470 | ------------------- | |
| 3471 | ||
| 3472 | * [Uninhabitable enums (those without any variants) no longer permit wildcard | |
| 3473 | match patterns][38069] | |
| 3474 | * In this release, references to uninhabited types can not be | |
| 3475 | pattern-matched. This was accidentally allowed in 1.15. | |
| 3476 | * [The compiler's `dead_code` lint now accounts for type aliases][38051]. | |
| 3477 | * [Ctrl-Z returns from `Stdin.read()` when reading from the console on | |
| 3478 | Windows][38274] | |
| 3479 | * [Clean up semantics of `self` in an import list][38313] | |
| 3b2f2976 XL |
3480 | * Reimplemented lifetime elision. This change was almost entirely compatible |
| 3481 | with existing code, but it did close a number of small bugs and loopholes, | |
| 3482 | as well as being more accepting in some other [cases][41105]. | |

| 476ff2be SL |
3560 | Version 1.15.0 (2017-02-02) |
| 3561 | =========================== | |
| 3562 | ||
| 3563 | Language | |
| 3564 | -------- | |
| 3565 | ||
| 3566 | * Basic procedural macros allowing custom `#[derive]`, aka "macros 1.1", are | |
| 3567 | stable. This allows popular code-generating crates like Serde and Diesel to | |
| 3568 | work ergonomically. [RFC 1681]. | |
| 3569 | * [Tuple structs may be empty. Unary and empty tuple structs may be instantiated | |
| 3570 | with curly braces][36868]. Part of [RFC 1506]. | |
| 3571 | * [A number of minor changes to name resolution have been activated][37127]. | |
| 3572 | They add up to more consistent semantics, allowing for future evolution of | |
| 3573 | Rust macros. Specified in [RFC 1560], see its section on ["changes"] for | |
| 3574 | details of what is different. The breaking changes here have been transitioned | |
| 3575 | through the [`legacy_imports`] lint since 1.14, with no known regressions. | |
| 3576 | * [In `macro_rules`, `path` fragments can now be parsed as type parameter | |
| 3577 | bounds][38279] | |
| 3578 | * [`?Sized` can be used in `where` clauses][37791] | |
| 3579 | * [There is now a limit on the size of monomorphized types and it can be | |
| 3580 | modified with the `#![type_size_limit]` crate attribute, similarly to | |
| 3581 | the `#![recursion_limit]` attribute][37789] | |
| 3582 | ||
| 3583 | Compiler | |
| 3584 | -------- | |
| 3585 | ||
| 3586 | * [On Windows, the compiler will apply dllimport attributes when linking to | |
| 3587 | extern functions][37973]. Additional attributes and flags can control which | |
| 3588 | library kind is linked and its name. [RFC 1717]. | |
| 3589 | * [Rust-ABI symbols are no longer exported from cdylibs][38117] | |
| 3590 | * [The `--test` flag works with procedural macro crates][38107] | |
| 3591 | * [Fix `extern "aapcs" fn` ABI][37814] | |
| 3592 | * [The `-C no-stack-check` flag is deprecated][37636]. It does nothing. | |
| 3593 | * [The `format!` expander recognizes incorrect `printf` and shell-style | |
| 3594 | formatting directives and suggests the correct format][37613]. | |
| 3595 | * [Only report one error for all unused imports in an import list][37456] | |
| 3596 | ||
| 3597 | Compiler Performance | |
| 3598 | -------------------- | |
| 3599 | ||
| 3600 | * [Avoid unnecessary `mk_ty` calls in `Ty::super_fold_with`][37705] | |
| 3601 | * [Avoid more unnecessary `mk_ty` calls in `Ty::super_fold_with`][37979] | |
| 3602 | * [Don't clone in `UnificationTable::probe`][37848] | |
| 3603 | * [Remove `scope_auxiliary` to cut RSS by 10%][37764] | |
| 3604 | * [Use small vectors in type walker][37760] | |
| 3605 | * [Macro expansion performance was improved][37701] | |
| 3606 | * [Change `HirVec<P<T>>` to `HirVec<T>` in `hir::Expr`][37642] | |
| 3607 | * [Replace FNV with a faster hash function][37229] | |
| 3608 | ||
| 3609 | Stabilized APIs | |
| 3610 | --------------- | |
| 3611 | ||
| 3612 | * [`std::iter::Iterator::min_by`] | |
| 3613 | * [`std::iter::Iterator::max_by`] | |
| 3614 | * [`std::os::*::fs::FileExt`] | |
| 3615 | * [`std::sync::atomic::Atomic*::get_mut`] | |
| 3616 | * [`std::sync::atomic::Atomic*::into_inner`] | |
| 3617 | * [`std::vec::IntoIter::as_slice`] | |
| 3618 | * [`std::vec::IntoIter::as_mut_slice`] | |
| 3619 | * [`std::sync::mpsc::Receiver::try_iter`] | |
| 3620 | * [`std::os::unix::process::CommandExt::before_exec`] | |
| 3621 | * [`std::rc::Rc::strong_count`] | |
| 3622 | * [`std::rc::Rc::weak_count`] | |
| 3623 | * [`std::sync::Arc::strong_count`] | |
| 3624 | * [`std::sync::Arc::weak_count`] | |
| 3625 | * [`std::char::encode_utf8`] | |
| 3626 | * [`std::char::encode_utf16`] | |
| 3627 | * [`std::cell::Ref::clone`] | |
| 3628 | * [`std::io::Take::into_inner`] | |
| 3629 | ||
| 3630 | Libraries | |
| 3631 | --------- | |
| 3632 | ||
| 3633 | * [The standard sorting algorithm has been rewritten for dramatic performance | |
| 3634 | improvements][38192]. It is a hybrid merge sort, drawing influences from | |
| 3635 | Timsort. Previously it was a naive merge sort. | |
| 3636 | * [`Iterator::nth` no longer has a `Sized` bound][38134] | |
| 3637 | * [`Extend<&T>` is specialized for `Vec` where `T: Copy`][38182] to improve | |
| 3638 | performance. | |
| 3639 | * [`chars().count()` is much faster][37888] and so are [`chars().last()` | |
| 3640 | and `char_indices().last()`][37882] | |
| 3641 | * [Fix ARM Objective-C ABI in `std::env::args`][38146] | |
| 3642 | * [Chinese characters display correctly in `fmt::Debug`][37855] | |
| 3643 | * [Derive `Default` for `Duration`][37699] | |
| 3644 | * [Support creation of anonymous pipes on WinXP/2k][37677] | |
| 3645 | * [`mpsc::RecvTimeoutError` implements `Error`][37527] | |
| 3646 | * [Don't pass overlapped handles to processes][38835] | |
| 3647 | ||
| 3648 | Cargo | |
| 3649 | ----- | |
| 3650 | ||
| 3651 | * [In this release, Cargo build scripts no longer have access to the `OUT_DIR` | |
| 3652 | environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They | |
| 3653 | should instead check the variable at runtime with `std::env`. That the value | |
| 3654 | was set at build time was a bug, and incorrect when cross-compiling. This | |
| 3655 | change is known to cause breakage. | |
| 3656 | * [Add `--all` flag to `cargo test`][cargo/3221] | |
| 3657 | * [Compile statically against the MSVC CRT][cargo/3363] | |
| 3658 | * [Mix feature flags into fingerprint/metadata shorthash][cargo/3102] | |
| 3659 | * [Link OpenSSL statically on OSX][cargo/3311] | |
| 3660 | * [Apply new fingerprinting to build dir outputs][cargo/3310] | |
| 3661 | * [Test for bad path overrides with summaries][cargo/3336] | |
| 3662 | * [Require `cargo install --vers` to take a semver version][cargo/3338] | |
| 3663 | * [Fix retrying crate downloads for network errors][cargo/3348] | |
| 3664 | * [Implement string lookup for `build.rustflags` config key][cargo/3356] | |
| 3665 | * [Emit more info on --message-format=json][cargo/3319] | |
| 3666 | * [Assume `build.rs` in the same directory as `Cargo.toml` is a build script][cargo/3361] | |
| 3667 | * [Don't ignore errors in workspace manifest][cargo/3409] | |
| 3668 | * [Fix `--message-format JSON` when rustc emits non-JSON warnings][cargo/3410] | |
| 3669 | ||
| 3670 | Tooling | |
| 3671 | ------- | |
| 3672 | ||
| 3673 | * [Test runners (binaries built with `--test`) now support a `--list` argument | |
| 3674 | that lists the tests it contains][38185] | |
| 3675 | * [Test runners now support a `--exact` argument that makes the test filter | |
| 3676 | match exactly, instead of matching only a substring of the test name][38181] | |
| 3677 | * [rustdoc supports a `--playground-url` flag][37763] | |
| 3678 | * [rustdoc provides more details about `#[should_panic]` errors][37749] | |
| 3679 | ||
| 3680 | Misc | |
| 3681 | ---- | |
| 3682 | ||
| 3683 | * [The Rust build system is now written in Rust][37817]. The Makefiles may | |
| 3684 | continue to be used in this release by passing `--disable-rustbuild` to the | |
| 3685 | configure script, but they will be deleted soon. Note that the new build | |
| 3686 | system uses a different on-disk layout that will likely affect any scripts | |
| 3687 | building Rust. | |
| 3688 | * [Rust supports i686-unknown-openbsd][38086]. Tier 3 support. No testing or | |
| 3689 | releases. | |
| 3690 | * [Rust supports the MSP430][37627]. Tier 3 support. No testing or releases. | |
| 3691 | * [Rust supports the ARMv5TE architecture][37615]. Tier 3 support. No testing or | |
| 3692 | releases. | |
| 3693 | ||
| 3694 | Compatibility Notes | |
| 3695 | ------------------- | |
| 3696 | ||
| 3697 | * [A number of minor changes to name resolution have been activated][37127]. | |
| 3698 | They add up to more consistent semantics, allowing for future evolution of | |
| 3699 | Rust macros. Specified in [RFC 1560], see its section on ["changes"] for | |
| 3700 | details of what is different. The breaking changes here have been transitioned | |
| 3701 | through the [`legacy_imports`] lint since 1.14, with no known regressions. | |
| 3702 | * [In this release, Cargo build scripts no longer have access to the `OUT_DIR` | |
| 3703 | environment variable at build time via `env!("OUT_DIR")`][cargo/3368]. They | |
| 3704 | should instead check the variable at runtime with `std::env`. That the value | |
| 3705 | was set at build time was a bug, and incorrect when cross-compiling. This | |
| 3706 | change is known to cause breakage. | |
| 3707 | * [Higher-ranked lifetimes are no longer allowed to appear _only_ in associated | |
| 3708 | types][33685]. The [`hr_lifetime_in_assoc_type` lint] has been a warning since | |
| 3709 | 1.10 and is now an error by default. It will become a hard error in the near | |
| 3710 | future. | |
| 3711 | * [The semantics relating modules to file system directories are changing in | |
| 3712 | minor ways][37602]. This is captured in the new `legacy_directory_ownership` | |
| 3713 | lint, which is a warning in this release, and will become a hard error in the | |
| 3714 | future. | |
| 3715 | * [Rust-ABI symbols are no longer exported from cdylibs][38117] | |
| 3716 | * [Once `Peekable` peeks a `None` it will return that `None` without re-querying | |
| 3717 | the underlying iterator][37834] | |

| 3922 | ------------------- | |
| 3923 | ||
| 3924 | * [A number of forward-compatibility lints used by the compiler | |
| 3925 | to gradually introduce language changes have been converted | |
| 3926 | to deny by default][36894]: | |
| 3927 | - ["use of inaccessible extern crate erroneously allowed"][36886] | |
| 3928 | - ["type parameter default erroneously allowed in invalid location"][36887] | |
| 3929 | - ["detects super or self keywords at the beginning of global path"][36888] | |
| 3930 | - ["two overlapping inherent impls define an item with the same name | |
| 3931 | were erroneously allowed"][36889] | |
| 3932 | - ["floating-point constants cannot be used in patterns"][36890] | |
| 3933 | - ["constants of struct or enum type can only be used in a pattern if | |
| 3934 | the struct or enum has `#[derive(PartialEq, Eq)]`"][36891] | |
| 3935 | - ["lifetimes or labels named `'_` were erroneously allowed"][36892] | |
| 3936 | * [Prohibit patterns in trait methods without bodies][37378] | |
| 3937 | * [The atomic `Ordering` enum may not be matched exhaustively][37351] | |

| 3939 | * [The `$crate` macro variable is accepted in fewer locations][37213] | |
| 3940 | * [Impls specifying extra region requirements beyond the trait | |
| 3941 | they implement are rejected][37167] | |
| 3942 | * [Enums may not be unsized][37111]. Unsized enums are intended to | |
| 3943 | work but never have. For now they are forbidden. | |
| 3944 | * [Enforce the shadowing restrictions from RFC 1560 for today's macros][36767] | |

| 4307 | ||
| 4308 | Highlights | |
| 4309 | ---------- | |
| 4310 | ||
| 7cac9316 | 4311 | * [`rustc` translates code to LLVM IR via its own "middle" IR (MIR)](https://github.com/rust-lang/rust/pull/34096). |
| 5bcae85e SL |
4312 | This translation pass is far simpler than the previous AST->LLVM pass, and |
| 4313 | creates opportunities to perform new optimizations directly on the MIR. It | |
| 7cac9316 | 4314 | was previously described [on the Rust blog](https://blog.rust-lang.org/2016/04/19/MIR.html). |
| 5bcae85e | 4315 | * [`rustc` presents a new, more readable error format, along with |
| 7cac9316 | 4316 | machine-readable JSON error output for use by IDEs](https://github.com/rust-lang/rust/pull/35401). |
| 5bcae85e | 4317 | Most common editors supporting Rust have been updated to work with it. It was |
| 7cac9316 | 4318 | previously described [on the Rust blog](https://blog.rust-lang.org/2016/08/10/Shape-of-errors-to-come.html). |

4794 | Version 1.9.0 (2016-05-26) |
| 4795 | ========================== | |
| 4796 | ||
| 4797 | Language | |
| 4798 | -------- | |
| 4799 | ||
| 4800 | * The `#[deprecated]` attribute when applied to an API will generate | |
| 4801 | warnings when used. The warnings may be suppressed with | |
| 4802 | `#[allow(deprecated)]`. [RFC 1270]. | |
| 4803 | * [`fn` item types are zero sized, and each `fn` names a unique | |
| 4804 | type][1.9fn]. This will break code that transmutes `fn`s, so calling | |
| 4805 | `transmute` on a `fn` type will generate a warning for a few cycles, | |
| 4806 | then will be converted to an error. | |
| 4807 | * [Field and method resolution understand visibility, so private | |
| 4808 | fields and methods cannot prevent the proper use of public fields | |
| 4809 | and methods][1.9fv]. | |
| 4810 | * [The parser considers unicode codepoints in the | |
| 4811 | `PATTERN_WHITE_SPACE` category to be whitespace][1.9ws]. | |

| 4903 | Libraries | |
| 4904 | --------- | |
| 4905 | ||
| 4906 | * [`std::sync::Once` is poisoned if its initialization function | |
| 4907 | fails][1.9o]. | |
| 4908 | * [`cell::Ref` and `cell::RefMut` can contain unsized types][1.9cu]. | |
| 4909 | * [Most types implement `fmt::Debug`][1.9db]. | |
| 4910 | * [The default buffer size used by `BufReader` and `BufWriter` was | |
| 4911 | reduced to 8K, from 64K][1.9bf]. This is in line with the buffer size | |
| 4912 | used by other languages. | |
| 4913 | * [`Instant`, `SystemTime` and `Duration` implement `+=` and `-=`. | |
| 4914 | `Duration` additionally implements `*=` and `/=`][1.9ta]. | |
| 4915 | * [`Skip` is a `DoubleEndedIterator`][1.9sk]. | |
| 4916 | * [`From<[u8; 4]>` is implemented for `Ipv4Addr`][1.9fi]. | |
| 4917 | * [`Chain` implements `BufRead`][1.9ch]. | |
| 4918 | * [`HashMap`, `HashSet` and iterators are covariant][1.9hc]. | |
| 4919 | ||
| 4920 | Cargo | |
| 4921 | ----- | |
| 4922 | ||
| 4923 | * [Cargo can now run concurrently][1.9cc]. | |
| 4924 | * [Top-level overrides allow specific revisions of crates to be | |
| 4925 | overridden through the entire crate graph][1.9ct]. This is intended | |
| 4926 | to make upgrades easier for large projects, by allowing crates to be | |
| 4927 | forked temporarily until they've been upgraded and republished. | |
| 4928 | * [Cargo exports a `CARGO_PKG_AUTHORS` environment variable][1.9cp]. | |
| 4929 | * [Cargo will pass the contents of the `RUSTFLAGS` variable to `rustc` | |
| 4930 | on the commandline][1.9cf]. `rustc` arguments can also be specified | |
| 4931 | in the `build.rustflags` configuration key. | |
| 4932 | ||
| 4933 | Performance | |
| 4934 | ----------- | |
| 4935 | ||
| c30ab7b3 | 4936 | * [The time complexity of comparing variables for equivalence during type |
| a7813a04 XL |
4937 | unification is reduced from _O_(_n_!) to _O_(_n_)][1.9tu]. This leads |
| 4938 | to major compilation time improvement in some scenarios. | |
| 54a0048b SL |
4939 | * [`ToString` is specialized for `str`, giving it the same performance |
| 4940 | as `to_owned`][1.9ts]. | |
| 4941 | * [Spawning processes with `Command::output` no longer creates extra | |
| 4942 | threads][1.9sp]. | |
| 4943 | * [`#[derive(PartialEq)]` and `#[derive(PartialOrd)]` emit less code | |
| 4944 | for C-like enums][1.9cl]. | |
| 4945 | ||
| 4946 | Misc | |
| 4947 | ---- | |
| 4948 | ||
| 4949 | * [Passing the `--quiet` flag to a test runner will produce | |
| 4950 | much-abbreviated output][1.9q]. | |
| 4951 | * The Rust Project now publishes std binaries for the | |
| 4952 | `mips-unknown-linux-musl`, `mipsel-unknown-linux-musl`, and | |
| 4953 | `i586-pc-windows-msvc` targets. | |
| 4954 | ||
| 4955 | Compatibility Notes | |
| 4956 | ------------------- | |
| 4957 | ||
| 4958 | * [`std::sync::Once` is poisoned if its initialization function | |
| 4959 | fails][1.9o]. | |
| 4960 | * [It is illegal to define methods with the same name in overlapping | |
| 4961 | inherent `impl` blocks][1.9sn]. | |
| 4962 | * [`fn` item types are zero sized, and each `fn` names a unique | |
| 4963 | type][1.9fn]. This will break code that transmutes `fn`s, so calling | |
| 4964 | `transmute` on a `fn` type will generate a warning for a few cycles, | |
| 4965 | then will be converted to an error. | |
| 4966 | * [Improvements to const evaluation may trigger new errors when integer | |
| 4967 | literals are out of range][1.9ce]. | |

5082 | Version 1.8.0 (2016-04-14) |
| 5083 | ========================== | |
| 5084 | ||
| 5085 | Language | |
| 5086 | -------- | |
| 5087 | ||
| 5088 | * Rust supports overloading of compound assignment statements like | |
| 5089 | `+=` by implementing the [`AddAssign`], [`SubAssign`], | |
| 5090 | [`MulAssign`], [`DivAssign`], [`RemAssign`], [`BitAndAssign`], | |
| 5091 | [`BitOrAssign`], [`BitXorAssign`], [`ShlAssign`], or [`ShrAssign`] | |
| 5092 | traits. [RFC 953]. | |
| 5093 | * Empty structs can be defined with braces, as in `struct Foo { }`, in | |
| 5094 | addition to the non-braced form, `struct Foo;`. [RFC 218]. | |
| 5095 | ||
| 5096 | Libraries | |
| 5097 | --------- | |
| 5098 | ||
| 5099 | * Stabilized APIs: | |
| 5100 | * [`str::encode_utf16`][] (renamed from `utf16_units`) | |
| 5101 | * [`str::EncodeUtf16`][] (renamed from `Utf16Units`) | |
| 5102 | * [`Ref::map`] | |
| 5103 | * [`RefMut::map`] | |
| 5104 | * [`ptr::drop_in_place`] | |
| 5105 | * [`time::Instant`] | |
| 5106 | * [`time::SystemTime`] | |
| 5107 | * [`Instant::now`] | |
| 5108 | * [`Instant::duration_since`][] (renamed from `duration_from_earlier`) | |
| 5109 | * [`Instant::elapsed`] | |
| 5110 | * [`SystemTime::now`] | |
| 5111 | * [`SystemTime::duration_since`][] (renamed from `duration_from_earlier`) | |
| 5112 | * [`SystemTime::elapsed`] | |
| 5113 | * Various `Add`/`Sub` impls for `Time` and `SystemTime` | |
| 5114 | * [`SystemTimeError`] | |
| 5115 | * [`SystemTimeError::duration`] | |
| 5116 | * Various impls for `SystemTimeError` | |
| 5117 | * [`UNIX_EPOCH`] | |
| 5118 | * [`AddAssign`], [`SubAssign`], [`MulAssign`], [`DivAssign`], | |
| 5119 | [`RemAssign`], [`BitAndAssign`], [`BitOrAssign`], | |
| 5120 | [`BitXorAssign`], [`ShlAssign`], [`ShrAssign`]. | |
| 5121 | * [The `write!` and `writeln!` macros correctly emit errors if any of | |
| 5122 | their arguments can't be formatted][1.8w]. | |
| 5123 | * [Various I/O functions support large files on 32-bit Linux][1.8l]. | |
| 5124 | * [The Unix-specific `raw` modules, which contain a number of | |
| 5125 | redefined C types are deprecated][1.8r], including `os::raw::unix`, | |
| 5126 | `os::raw::macos`, and `os::raw::linux`. These modules defined types | |
| 5127 | such as `ino_t` and `dev_t`. The inconsistency of these definitions | |
| 5128 | across platforms was making it difficult to implement `std` | |
| 5129 | correctly. Those that need these definitions should use the `libc` | |
| 5130 | crate. [RFC 1415]. | |
| 5131 | * The Unix-specific `MetadataExt` traits, including | |
| 5132 | `os::unix::fs::MetadataExt`, which expose values such as inode | |
| 5133 | numbers [no longer return platform-specific types][1.8r], but | |
| 5134 | instead return widened integers. [RFC 1415]. | |
| 5135 | * [`btree_set::{IntoIter, Iter, Range}` are covariant][1.8cv]. | |
| 5136 | * [Atomic loads and stores are not volatile][1.8a]. | |
| 5137 | * [All types in `sync::mpsc` implement `fmt::Debug`][1.8mp]. | |
| 5138 | ||
| 5139 | Performance | |
| 5140 | ----------- | |
| 5141 | ||
| 5142 | * [Inlining hash functions lead to a 3% compile-time improvement in | |
| 5143 | some workloads][1.8h]. | |
| 5144 | * When using jemalloc, its symbols are [unprefixed so that it | |
| 5145 | overrides the libc malloc implementation][1.8h]. This means that for | |
| 5146 | rustc, LLVM is now using jemalloc, which results in a 6% | |
| 5147 | compile-time improvement on a specific workload. | |
| 5148 | * [Avoid quadratic growth in function size due to cleanups][1.8cu]. | |
| 5149 | ||
| 5150 | Misc | |
| 5151 | ---- | |
| 5152 | ||
| 5153 | * [32-bit MSVC builds finally implement unwinding][1.8ms]. | |
| 5154 | i686-pc-windows-msvc is now considered a tier-1 platform. | |
| 5155 | * [The `--print targets` flag prints a list of supported targets][1.8t]. | |
| 5156 | * [The `--print cfg` flag prints the `cfg`s defined for the current | |
| 5157 | target][1.8cf]. | |
| 5158 | * [`rustc` can be built with an new Cargo-based build system, written | |
| 5159 | in Rust][1.8b]. It will eventually replace Rust's Makefile-based | |
| 5160 | build system. To enable it configure with `configure --rustbuild`. | |
| 5161 | * [Errors for non-exhaustive `match` patterns now list up to 3 missing | |
| 5162 | variants while also indicating the total number of missing variants | |
| 5163 | if more than 3][1.8m]. | |
| 5164 | * [Executable stacks are disabled on Linux and BSD][1.8nx]. | |
| 5165 | * The Rust Project now publishes binary releases of the standard | |
| 5166 | library for a number of tier-2 targets: | |
| 5167 | `armv7-unknown-linux-gnueabihf`, `powerpc-unknown-linux-gnu`, | |
| 5168 | `powerpc64-unknown-linux-gnu`, `powerpc64le-unknown-linux-gnu` | |
| 5169 | `x86_64-rumprun-netbsd`. These can be installed with | |
| 5170 | tools such as [multirust][1.8mr]. | |
| 5171 | ||
| 5172 | Cargo | |
| 5173 | ----- | |
| 5174 | ||
| 5175 | * [`cargo init` creates a new Cargo project in the current | |
| 5176 | directory][1.8ci]. It is otherwise like `cargo new`. | |
| 5177 | * [Cargo has configuration keys for `-v` and | |
| 5178 | `--color`][1.8cc]. `verbose` and `color`, respectively, go in the | |
| 5179 | `[term]` section of `.cargo/config`. | |
| 5180 | * [Configuration keys that evaluate to strings or integers can be set | |
| 5181 | via environment variables][1.8ce]. For example the `build.jobs` key | |
| 5182 | can be set via `CARGO_BUILD_JOBS`. Environment variables take | |
| 5183 | precedence over config files. | |
| 5184 | * [Target-specific dependencies support Rust `cfg` syntax for | |
| 5185 | describing targets][1.8cfg] so that dependencies for multiple | |
| 5186 | targets can be specified together. [RFC 1361]. | |
| 5187 | * [The environment variables `CARGO_TARGET_ROOT`, `RUSTC`, and | |
| 5188 | `RUSTDOC` take precedence over the `build.target-dir`, | |
| 5189 | `build.rustc`, and `build.rustdoc` configuration values][1.8cv]. | |
| 5190 | * [The child process tree is killed on Windows when Cargo is | |
| 5191 | killed][1.8ck]. | |
| 5192 | * [The `build.target` configuration value sets the target platform, | |
| 5193 | like `--target`][1.8ct]. | |
| 5194 | ||
| 5195 | Compatibility Notes | |
| 5196 | ------------------- | |
| 5197 | ||
| 5198 | * [Unstable compiler flags have been further restricted][1.8u]. Since | |
| 5199 | 1.0 `-Z` flags have been considered unstable, and other flags that | |
| 5200 | were considered unstable additionally required passing `-Z | |
| 5201 | unstable-options` to access. Unlike unstable language and library | |
| 5202 | features though, these options have been accessible on the stable | |
| 5203 | release channel. Going forward, *new unstable flags will not be | |
| 5204 | available on the stable release channel*, and old unstable flags | |
| 5205 | will warn about their usage. In the future, all unstable flags will | |
| 5206 | be unavailable on the stable release channel. | |
| 5207 | * [It is no longer possible to `match` on empty enum variants using | |
| 5208 | the `Variant(..)` syntax][1.8v]. This has been a warning since 1.6. | |
| 5209 | * The Unix-specific `MetadataExt` traits, including | |
| 5210 | `os::unix::fs::MetadataExt`, which expose values such as inode | |
| 5211 | numbers [no longer return platform-specific types][1.8r], but | |
| 5212 | instead return widened integers. [RFC 1415]. | |
| 5213 | * [Modules sourced from the filesystem cannot appear within arbitrary | |
| a7813a04 | 5214 | blocks, but only within other modules][1.8mf]. |
| 7453a54e SL |
5215 | * [`--cfg` compiler flags are parsed strictly as identifiers][1.8c]. |
| 5216 | * On Unix, [stack overflow triggers a runtime abort instead of a | |
| 5217 | SIGSEGV][1.8so]. | |
| 5218 | * [`Command::spawn` and its equivalents return an error if any of | |
| 5219 | its command-line arguments contain interior `NUL`s][1.8n]. | |
| 5220 | * [Tuple and unit enum variants from other crates are in the type | |
| 5221 | namespace][1.8tn]. | |
| 5222 | * [On Windows `rustc` emits `.lib` files for the `staticlib` library | |
| 5223 | type instead of `.a` files][1.8st]. Additionally, for the MSVC | |
| 5224 | toolchain, `rustc` emits import libraries named `foo.dll.lib` | |
| 5225 | instead of `foo.lib`. | |

| 54a0048b SL |
5394 | * Soundness fixes to the interactions between associated types and |
| 5395 | lifetimes, specified in [RFC 1214], [now generate errors][1.7sf] for | |
| 5396 | code that violates the new rules. This is a significant change that | |
| 5397 | is known to break existing code, so it has emitted warnings for the | |
| 5398 | new error cases since 1.4 to give crate authors time to adapt. The | |
| 5399 | details of what is changing are subtle; read the RFC for more. | |
| 9cc50fc6 SL |
5400 | * [Several bugs in the compiler's visibility calculations were |
| 5401 | fixed][1.7v]. Since this was found to break significant amounts of | |
| 5402 | code, the new errors will be emitted as warnings for several release | |
| 5403 | cycles, under the `private_in_public` lint. | |
| 5404 | * Defaulted type parameters were accidentally accepted in positions | |
| 5405 | that were not intended. In this release, [defaulted type parameters | |
| 5406 | appearing outside of type definitions will generate a | |
| 5407 | warning][1.7d], which will become an error in future releases. | |
| 54a0048b SL |
5408 | * [Parsing "." as a float results in an error instead of 0][1.7p]. |
| 5409 | That is, `".".parse::<f32>()` returns `Err`, not `Ok(0.0)`. | |

5493 | Version 1.6.0 (2016-01-21) |
| 5494 | ========================== | |
| 5495 | ||
| 5496 | Language | |
| 5497 | -------- | |
| 5498 | ||
| 5499 | * The `#![no_std]` attribute causes a crate to not be linked to the | |
| 5500 | standard library, but only the [core library][1.6co], as described | |
| 5501 | in [RFC 1184]. The core library defines common types and traits but | |
| 5502 | has no platform dependencies whatsoever, and is the basis for Rust | |
| 5503 | software in environments that cannot support a full port of the | |
| 5504 | standard library, such as operating systems. Most of the core | |
| 5505 | library is now stable. | |
| 5506 | ||
| 5507 | Libraries | |
| 5508 | --------- | |
| 5509 | ||
| 5510 | * Stabilized APIs: | |
| 9cc50fc6 SL |
5511 | [`Read::read_exact`], |
| 5512 | [`ErrorKind::UnexpectedEof`][] (renamed from `UnexpectedEOF`), | |
| 5513 | [`fs::DirBuilder`], [`fs::DirBuilder::new`], | |
| 92a42be0 SL |
5514 | [`fs::DirBuilder::recursive`], [`fs::DirBuilder::create`], |
| 5515 | [`os::unix::fs::DirBuilderExt`], | |
| 5516 | [`os::unix::fs::DirBuilderExt::mode`], [`vec::Drain`], | |
| 5517 | [`vec::Vec::drain`], [`string::Drain`], [`string::String::drain`], | |
| 5518 | [`vec_deque::Drain`], [`vec_deque::VecDeque::drain`], | |
| 5519 | [`collections::hash_map::Drain`], | |
| 5520 | [`collections::hash_map::HashMap::drain`], | |
| 5521 | [`collections::hash_set::Drain`], | |
| 5522 | [`collections::hash_set::HashSet::drain`], | |
| 5523 | [`collections::binary_heap::Drain`], | |
| 5524 | [`collections::binary_heap::BinaryHeap::drain`], | |
| 9cc50fc6 | 5525 | [`Vec::extend_from_slice`][] (renamed from `push_all`), |
| 92a42be0 | 5526 | [`Mutex::get_mut`], [`Mutex::into_inner`], [`RwLock::get_mut`], |
| 9cc50fc6 SL |
5527 | [`RwLock::into_inner`], |
| 5528 | [`Iterator::min_by_key`][] (renamed from `min_by`), | |
| 5529 | [`Iterator::max_by_key`][] (renamed from `max_by`). | |
| 92a42be0 SL |
5530 | * The [core library][1.6co] is stable, as are most of its APIs. |
| 5531 | * [The `assert_eq!` macro supports arguments that don't implement | |
| 5532 | `Sized`][1.6ae], such as arrays. In this way it behaves more like | |
| 5533 | `assert!`. | |
| 5534 | * Several timer functions that take duration in milliseconds [are | |
| 5535 | deprecated in favor of those that take `Duration`][1.6ms]. These | |
| 5536 | include `Condvar::wait_timeout_ms`, `thread::sleep_ms`, and | |
| 9cc50fc6 | 5537 | `thread::park_timeout_ms`. |
| 92a42be0 SL |
5538 | * The algorithm by which `Vec` reserves additional elements was |
| 5539 | [tweaked to not allocate excessive space][1.6a] while still growing | |
| 5540 | exponentially. | |
| 5541 | * `From` conversions are [implemented from integers to floats][1.6f] | |
| 5542 | in cases where the conversion is lossless. Thus they are not | |
| 5543 | implemented for 32-bit ints to `f32`, nor for 64-bit ints to `f32` | |
| 5544 | or `f64`. They are also not implemented for `isize` and `usize` | |
| 5545 | because the implementations would be platform-specific. `From` is | |
| 5546 | also implemented from `f32` to `f64`. | |
| 5547 | * `From<&Path>` and `From<PathBuf>` are implemented for `Cow<Path>`. | |
| 5548 | * `From<T>` is implemented for `Box<T>`, `Rc<T>` and `Arc<T>`. | |
| 5549 | * `IntoIterator` is implemented for `&PathBuf` and `&Path`. | |
| 5550 | * [`BinaryHeap` was refactored][1.6bh] for modest performance | |
| 5551 | improvements. | |
| 5552 | * Sorting slices that are already sorted [is 50% faster in some | |
| 5553 | cases][1.6s]. | |
| 5554 | ||
| 5555 | Cargo | |
| 5556 | ----- | |
| 5557 | ||
| 5558 | * Cargo will look in `$CARGO_HOME/bin` for subcommands [by default][1.6c]. | |
| 5559 | * Cargo build scripts can specify their dependencies by emitting the | |
| 5560 | [`rerun-if-changed`][1.6rr] key. | |
| 5561 | * crates.io will reject publication of crates with dependencies that | |
| 5562 | have a wildcard version constraint. Crates with wildcard | |
| 5563 | dependencies were seen to cause a variety of problems, as described | |
| 9cc50fc6 SL |
5564 | in [RFC 1241]. Since 1.5 publication of such crates has emitted a |
| 5565 | warning. | |
| 92a42be0 SL |
5566 | * `cargo clean` [accepts a `--release` flag][1.6cc] to clean the |
| 5567 | release folder. A variety of artifacts that Cargo failed to clean | |
| 5568 | are now correctly deleted. | |
| 5569 | ||
| 5570 | Misc | |
| 5571 | ---- | |
| 5572 | ||
| 5573 | * The `unreachable_code` lint [warns when a function call's argument | |
| 5574 | diverges][1.6dv]. | |
| 5575 | * The parser indicates [failures that may be caused by | |
| 5576 | confusingly-similar Unicode characters][1.6uc] | |
| 5577 | * Certain macro errors [are reported at definition time][1.6m], not | |
| 5578 | expansion. | |
| 5579 | ||
| 5580 | Compatibility Notes | |
| 5581 | ------------------- | |
| 5582 | ||
| 5583 | * The compiler no longer makes use of the [`RUST_PATH`][1.6rp] | |
| 5584 | environment variable when locating crates. This was a pre-cargo | |
| 5585 | feature for integrating with the package manager that was | |
| 5586 | accidentally never removed. | |
| 5587 | * [A number of bugs were fixed in the privacy checker][1.6p] that | |
| 5588 | could cause previously-accepted code to break. | |
| 5589 | * [Modules and unit/tuple structs may not share the same name][1.6ts]. | |

5590 | * [Bugs in pattern matching unit structs were fixed][1.6us]. The tuple |
| 5591 | struct pattern syntax (`Foo(..)`) can no longer be used to match | |
| 5592 | unit structs. This is a warning now, but will become an error in | |
| 5593 | future releases. Patterns that share the same name as a const are | |
| 5594 | now an error. | |
| 92a42be0 SL |
5595 | * A bug was fixed that causes [rustc not to apply default type |
| 5596 | parameters][1.6xc] when resolving certain method implementations of | |
| 5597 | traits defined in other crates. | |

5648 | Version 1.5.0 (2015-12-10) |
| 5649 | ========================== | |
| 5650 | ||
| 5651 | * ~700 changes, numerous bugfixes | |
| 5652 | ||
| 5653 | Highlights | |
| 5654 | ---------- | |
| 5655 | ||
| 5656 | * Stabilized APIs: | |
| 5657 | [`BinaryHeap::from`], [`BinaryHeap::into_sorted_vec`], | |
| 5658 | [`BinaryHeap::into_vec`], [`Condvar::wait_timeout`], | |
| 5659 | [`FileTypeExt::is_block_device`], [`FileTypeExt::is_char_device`], | |
| 5660 | [`FileTypeExt::is_fifo`], [`FileTypeExt::is_socket`], | |
| 5661 | [`FileTypeExt`], [`Formatter::alternate`], [`Formatter::fill`], | |
| 5662 | [`Formatter::precision`], [`Formatter::sign_aware_zero_pad`], | |
| 5663 | [`Formatter::sign_minus`], [`Formatter::sign_plus`], | |
| 5664 | [`Formatter::width`], [`Iterator::cmp`], [`Iterator::eq`], | |
| 5665 | [`Iterator::ge`], [`Iterator::gt`], [`Iterator::le`], | |
| 5666 | [`Iterator::lt`], [`Iterator::ne`], [`Iterator::partial_cmp`], | |
| 5667 | [`Path::canonicalize`], [`Path::exists`], [`Path::is_dir`], | |
| 5668 | [`Path::is_file`], [`Path::metadata`], [`Path::read_dir`], | |
| 5669 | [`Path::read_link`], [`Path::symlink_metadata`], | |
| 5670 | [`Utf8Error::valid_up_to`], [`Vec::resize`], | |
| 5671 | [`VecDeque::as_mut_slices`], [`VecDeque::as_slices`], | |
| 5672 | [`VecDeque::insert`], [`VecDeque::shrink_to_fit`], | |
| 5673 | [`VecDeque::swap_remove_back`], [`VecDeque::swap_remove_front`], | |
| 5674 | [`slice::split_first_mut`], [`slice::split_first`], | |
| 5675 | [`slice::split_last_mut`], [`slice::split_last`], | |
| 5676 | [`char::from_u32_unchecked`], [`fs::canonicalize`], | |
| 5677 | [`str::MatchIndices`], [`str::RMatchIndices`], | |
| 5678 | [`str::match_indices`], [`str::rmatch_indices`], | |
| 5679 | [`str::slice_mut_unchecked`], [`string::ParseError`]. | |
| 5680 | * Rust applications hosted on crates.io can be installed locally to | |
| 5681 | `~/.cargo/bin` with the [`cargo install`] command. Among other | |
| 5682 | things this makes it easier to augment Cargo with new subcommands: | |
| 5683 | when a binary named e.g. `cargo-foo` is found in `$PATH` it can be | |
| 5684 | invoked as `cargo foo`. | |
| 5685 | * Crates with wildcard (`*`) dependencies will [emit warnings when | |
| 5686 | published][1.5w]. In 1.6 it will no longer be possible to publish | |
| 5687 | crates with wildcard dependencies. | |
| 5688 | ||
| 5689 | Breaking Changes | |
| 5690 | ---------------- | |
| 5691 | ||
| 5692 | * The rules determining when a particular lifetime must outlive | |
| 5693 | a particular value (known as '[dropck]') have been [modified | |
| 5694 | to not rely on parametricity][1.5p]. | |
| 5695 | * [Implementations of `AsRef` and `AsMut` were added to `Box`, `Rc`, | |
| 5696 | and `Arc`][1.5a]. Because these smart pointer types implement | |
| 5697 | `Deref`, this causes breakage in cases where the interior type | |
| 5698 | contains methods of the same name. | |
| 5699 | * [Correct a bug in Rc/Arc][1.5c] that caused [dropck] to be unaware | |
| 5700 | that they could drop their content. Soundness fix. | |
| 5701 | * All method invocations are [properly checked][1.5wf1] for | |
| 5702 | [well-formedness][1.5wf2]. Soundness fix. | |
| 5703 | * Traits whose supertraits contain `Self` are [not object | |
| 5704 | safe][1.5o]. Soundness fix. | |
| 5705 | * Target specifications support a [`no_default_libraries`][1.5nd] | |
| 5706 | setting that controls whether `-nodefaultlibs` is passed to the | |
| 5707 | linker, and in turn the `is_like_windows` setting no longer affects | |
| 5708 | the `-nodefaultlibs` flag. | |
| 5709 | * `#[derive(Show)]`, long-deprecated, [has been removed][1.5ds]. | |
| 5710 | * The `#[inline]` and `#[repr]` attributes [can only appear | |
| 5711 | in valid locations][1.5at]. | |
| 5712 | * Native libraries linked from the local crate are [passed to | |
| 5713 | the linker before native libraries from upstream crates][1.5nl]. | |
| 5714 | * Two rarely-used attributes, `#[no_debug]` and | |
| 5715 | `#[omit_gdb_pretty_printer_section]` [are feature gated][1.5fg]. | |
| 5716 | * Negation of unsigned integers, which has been a warning for | |
| 5717 | several releases, [is now behind a feature gate and will | |
| 5718 | generate errors][1.5nu]. | |
| 5719 | * The parser accidentally accepted visibility modifiers on | |
| 5720 | enum variants, a bug [which has been fixed][1.5ev]. | |
| 5721 | * [A bug was fixed that allowed `use` statements to import unstable | |
| 5722 | features][1.5use]. | |
| 5723 | ||
| 5724 | Language | |
| 5725 | -------- | |
| 5726 | ||
| 5727 | * When evaluating expressions at compile-time that are not | |
| 5728 | compile-time constants (const-evaluating expressions in non-const | |
| 5729 | contexts), incorrect code such as overlong bitshifts and arithmetic | |
| 5730 | overflow will [generate a warning instead of an error][1.5ce], | |
| 5731 | delaying the error until runtime. This will allow the | |
| 5732 | const-evaluator to be expanded in the future backwards-compatibly. | |
| 5733 | * The `improper_ctypes` lint [no longer warns about using `isize` and | |
| 5734 | `usize` in FFI][1.5ict]. | |
| 5735 | ||
| 5736 | Libraries | |
| 5737 | --------- | |
| 5738 | ||
| 5739 | * `Arc<T>` and `Rc<T>` are [covariant with respect to `T` instead of | |
| 5740 | invariant][1.5c]. | |
| 5741 | * `Default` is [implemented for mutable slices][1.5d]. | |
| 5742 | * `FromStr` is [implemented for `SockAddrV4` and `SockAddrV6`][1.5s]. | |
| 5743 | * There are now `From` conversions [between floating point | |
| 5744 | types][1.5f] where the conversions are lossless. | |
| ff7c6d11 | 5745 | * There are now `From` conversions [between integer types][1.5i] where |
| b039eaaf SL |
5746 | the conversions are lossless. |
| 5747 | * [`fs::Metadata` implements `Clone`][1.5fs]. | |
| 5748 | * The `parse` method [accepts a leading "+" when parsing | |
| 5749 | integers][1.5pi]. | |
| 5750 | * [`AsMut` is implemented for `Vec`][1.5am]. | |
| 5751 | * The `clone_from` implementations for `String` and `BinaryHeap` [have | |
| 5752 | been optimized][1.5cf] and no longer rely on the default impl. | |
| 5753 | * The `extern "Rust"`, `extern "C"`, `unsafe extern "Rust"` and | |
| 5754 | `unsafe extern "C"` function types now [implement `Clone`, | |
| 5755 | `PartialEq`, `Eq`, `PartialOrd`, `Ord`, `Hash`, `fmt::Pointer`, and | |
| 5756 | `fmt::Debug` for up to 12 arguments][1.5fp]. | |
| 5757 | * [Dropping `Vec`s is much faster in unoptimized builds when the | |
| 5758 | element types don't implement `Drop`][1.5dv]. | |
| 5759 | * A bug that caused in incorrect behavior when [combining `VecDeque` | |
| 5760 | with zero-sized types][1.5vdz] was resolved. | |
| 5761 | * [`PartialOrd` for slices is faster][1.5po]. | |
| 5762 | ||
| 5763 | Miscellaneous | |
| 5764 | ------------- | |
| 5765 | ||
| 5766 | * [Crate metadata size was reduced by 20%][1.5md]. | |
| 5767 | * [Improvements to code generation reduced the size of libcore by 3.3 | |
| 5768 | MB and rustc's memory usage by 18MB][1.5m]. | |
| 5769 | * [Improvements to deref translation increased performance in | |
| 5770 | unoptimized builds][1.5dr]. | |
| 5771 | * Various errors in trait resolution [are deduplicated to only be | |
| 5772 | reported once][1.5te]. | |
| 5773 | * Rust has preliminary [support for rumprun kernels][1.5rr]. | |
| 5774 | * Rust has preliminary [support for NetBSD on amd64][1.5na]. | |

| 5866 | Version 1.4.0 (2015-10-29) | |
| 5867 | ========================== | |
| e9174d1e SL |
5868 | |
| 5869 | * ~1200 changes, numerous bugfixes | |
| 5870 | ||
| 5871 | Highlights | |
| 5872 | ---------- | |
| 5873 | ||
| 5874 | * Windows builds targeting the 64-bit MSVC ABI and linker (instead of | |
| 5875 | GNU) are now supported and recommended for use. | |
| 5876 | ||
| 5877 | Breaking Changes | |
| 5878 | ---------------- | |
| 5879 | ||
| 5880 | * [Several changes have been made to fix type soundness and improve | |
| 5881 | the behavior of associated types][sound]. See [RFC 1214]. Although | |
| 5882 | we have mostly introduced these changes as warnings this release, to | |
| 5883 | become errors next release, there are still some scenarios that will | |
| 5884 | see immediate breakage. | |
| 5885 | * [The `str::lines` and `BufRead::lines` iterators treat `\r\n` as | |
| 5886 | line breaks in addition to `\n`][crlf]. | |
| 5887 | * [Loans of `'static` lifetime extend to the end of a function][stat]. | |
| b039eaaf SL |
5888 | * [`str::parse` no longer introduces avoidable rounding error when |
| 5889 | parsing floating point numbers. Together with earlier changes to | |
| 5890 | float formatting/output, "round trips" like f.to_string().parse() | |
| 5891 | now preserve the value of f exactly. Additionally, leading plus | |
| 5892 | signs are now accepted][fp3]. | |
| 5893 | ||
| e9174d1e SL |
5894 | |
| 5895 | Language | |
| 5896 | -------- | |
| 5897 | ||
| 5898 | * `use` statements that import multiple items [can now rename | |
| 5899 | them][i], as in `use foo::{bar as kitten, baz as puppy}`. | |
| 5900 | * [Binops work correctly on fat pointers][binfat]. | |
| 5901 | * `pub extern crate`, which does not behave as expected, [issues a | |
| 5902 | warning][pec] until a better solution is found. | |
| 5903 | ||
| 5904 | Libraries | |
| 5905 | --------- | |
| 5906 | ||
| 5907 | * [Many APIs were stabilized][stab]: `<Box<str>>::into_string`, | |
| 5908 | [`Arc::downgrade`], [`Arc::get_mut`], [`Arc::make_mut`], | |
| 5909 | [`Arc::try_unwrap`], [`Box::from_raw`], [`Box::into_raw`], [`CStr::to_str`], | |

| 5911 | [`IntoRawFd::into_raw_fd`], [`IntoRawFd`], | |
| 5912 | `IntoRawHandle::into_raw_handle`, `IntoRawHandle`, | |
| 5913 | `IntoRawSocket::into_raw_socket`, `IntoRawSocket`, [`Rc::downgrade`], | |
| 5914 | [`Rc::get_mut`], [`Rc::make_mut`], [`Rc::try_unwrap`], [`Result::expect`], | |
| 5915 | [`String::into_boxed_str`], [`TcpStream::read_timeout`], | |

| 5919 | [`UdpSocket::write_timeout`], `Vec::append`, `Vec::split_off`, | |
| 5920 | [`VecDeque::append`], [`VecDeque::retain`], [`VecDeque::split_off`], | |
| 5921 | [`rc::Weak::upgrade`], [`rc::Weak`], [`slice::Iter::as_slice`], | |

| 5923 | [`str::Chars::as_str`], [`str::split_at_mut`], [`str::split_at`], | |
| 5924 | [`sync::Weak::upgrade`], [`sync::Weak`], [`thread::park_timeout`], | |
| 5925 | [`thread::sleep`]. | |
| 5926 | * [Some APIs were deprecated][dep]: `BTreeMap::with_b`, | |
| 5927 | `BTreeSet::with_b`, `Option::as_mut_slice`, `Option::as_slice`, | |
| 5928 | `Result::as_mut_slice`, `Result::as_slice`, `f32::from_str_radix`, | |
| 5929 | `f64::from_str_radix`. | |
| 5930 | * [Reverse-searching strings is faster with the 'two-way' | |
| 5931 | algorithm][s]. | |
| 5932 | * [`std::io::copy` allows `?Sized` arguments][cc]. | |
| 5933 | * The `Windows`, `Chunks`, and `ChunksMut` iterators over slices all | |
| 5934 | [override `count`, `nth` and `last` with an O(1) | |
| 5935 | implementation][it]. | |
| 5936 | * [`Default` is implemented for arrays up to `[T; 32]`][d]. | |
| 5937 | * [`IntoRawFd` has been added to the Unix-specific prelude, | |
| 5938 | `IntoRawSocket` and `IntoRawHandle` to the Windows-specific | |
| 5939 | prelude][pr]. | |
| 5940 | * [`Extend<String>` and `FromIterator<String` are both implemented for | |
| 5941 | `String`][es]. | |
| b039eaaf SL |
5942 | * [`IntoIterator` is implemented for references to `Option` and |
| 5943 | `Result`][into2]. | |
| e9174d1e | 5944 | * [`HashMap` and `HashSet` implement `Extend<&T>` where `T: |
| ff7c6d11 | 5945 | Copy`][ext] as part of [RFC 839]. This will cause type inference |
| b039eaaf | 5946 | breakage in rare situations. |
| e9174d1e SL |
5947 | * [`BinaryHeap` implements `Debug`][bh2]. |
| 5948 | * [`Borrow` and `BorrowMut` are implemented for fixed-size | |
| 5949 | arrays][bm]. | |
| b039eaaf | 5950 | * [`extern fn`s with the "Rust" and "C" ABIs implement common |
| e9174d1e SL |
5951 | traits including `Eq`, `Ord`, `Debug`, `Hash`][fp]. |
| 5952 | * [String comparison is faster][faststr]. | |
| b039eaaf SL |
5953 | * `&mut T` where `T: std::fmt::Write` [also implements |
| 5954 | `std::fmt::Write`][mutw]. | |
| 5955 | * [A stable regression in `VecDeque::push_back` and other | |
| ff7c6d11 | 5956 | capacity-altering methods that caused panics for zero-sized types |
| b039eaaf | 5957 | was fixed][vd]. |
| e9174d1e SL |
5958 | * [Function pointers implement traits for up to 12 parameters][fp2]. |
| 5959 | ||
| 5960 | Miscellaneous | |
| 5961 | ------------- | |
| 5962 | ||
| 5963 | * The compiler [no longer uses the 'morestack' feature to prevent | |
| 5964 | stack overflow][mm]. Instead it uses guard pages and stack | |
| 5965 | probes (though stack probes are not yet implemented on any platform | |
| 5966 | but Windows). | |
| 5967 | * [The compiler matches traits faster when projections are involved][p]. | |
| 5968 | * The 'improper_ctypes' lint [no longer warns about use of `isize` and | |
| 5969 | `usize`][ffi]. | |
| 5970 | * [Cargo now displays useful information about what its doing during | |
| 5971 | `cargo update`][cu]. | |

| 6045 | Version 1.3.0 (2015-09-17) | |
| c1a9b12d SL |
6046 | ============================== |
| 6047 | ||
| 6048 | * ~900 changes, numerous bugfixes | |
| 6049 | ||
| 6050 | Highlights | |
| 6051 | ---------- | |
| 6052 | ||
| 6053 | * The [new object lifetime defaults][nold] have been [turned | |
| 6054 | on][nold2] after a cycle of warnings about the change. Now types | |
| 6055 | like `&'a Box<Trait>` (or `&'a Rc<Trait>`, etc) will change from | |
| 6056 | being interpreted as `&'a Box<Trait+'a>` to `&'a | |
| 6057 | Box<Trait+'static>`. | |
| 6058 | * [The Rustonomicon][nom] is a new book in the official documentation | |
| 6059 | that dives into writing unsafe Rust. | |
| 6060 | * The [`Duration`] API, [has been stabilized][ds]. This basic unit of | |
| 6061 | timekeeping is employed by other std APIs, as well as out-of-tree | |
| 6062 | time crates. | |
| 6063 | ||
| 6064 | Breaking Changes | |
| 6065 | ---------------- | |
| 6066 | ||
| 6067 | * The [new object lifetime defaults][nold] have been [turned | |
| 6068 | on][nold2] after a cycle of warnings about the change. | |
| 6069 | * There is a known [regression][lr] in how object lifetime elision is | |
| 6070 | interpreted, the proper solution for which is undetermined. | |
| 6071 | * The `#[prelude_import]` attribute, an internal implementation | |
| 6072 | detail, was accidentally stabilized previously. [It has been put | |
| 6073 | behind the `prelude_import` feature gate][pi]. This change is | |
| 6074 | believed to break no existing code. | |
| 6075 | * The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is | |
| 6076 | [more sane for dynamically sized types][dst3]. Code that relied on | |
| 6077 | the previous behavior is thought to be broken. | |
| 6078 | * The `dropck` rules, which checks that destructors can't access | |
| 6079 | destroyed values, [have been updated][dropck] to match the | |
| 6080 | [RFC][dropckrfc]. This fixes some soundness holes, and as such will | |
| 6081 | cause some previously-compiling code to no longer build. | |
| 6082 | ||
| 6083 | Language | |
| 6084 | -------- | |
| 6085 | ||
| 6086 | * The [new object lifetime defaults][nold] have been [turned | |
| 6087 | on][nold2] after a cycle of warnings about the change. | |
| 6088 | * Semicolons may [now follow types and paths in | |
| 6089 | macros](https://github.com/rust-lang/rust/pull/27000). | |
| 6090 | * The behavior of [`size_of_val`][dst1] and [`align_of_val`][dst2] is | |
| 6091 | [more sane for dynamically sized types][dst3]. Code that relied on | |
| 6092 | the previous behavior is not known to exist, and suspected to be | |
| 6093 | broken. | |
| 6094 | * `'static` variables [may now be recursive][st]. | |
| 6095 | * `ref` bindings choose between [`Deref`] and [`DerefMut`] | |
| 6096 | implementations correctly. | |
| 6097 | * The `dropck` rules, which checks that destructors can't access | |
| 6098 | destroyed values, [have been updated][dropck] to match the | |
| 6099 | [RFC][dropckrfc]. | |
| 6100 | ||
| 6101 | Libraries | |
| 6102 | --------- | |
| 6103 | ||
| 6104 | * The [`Duration`] API, [has been stabilized][ds], as well as the | |
| 6105 | `std::time` module, which presently contains only `Duration`. | |
| 6106 | * `Box<str>` and `Box<[T]>` both implement `Clone`. | |
| 6107 | * The owned C string, [`CString`], implements [`Borrow`] and the | |
| 6108 | borrowed C string, [`CStr`], implements [`ToOwned`]. The two of | |
| 6109 | these allow C strings to be borrowed and cloned in generic code. | |
| 6110 | * [`CStr`] implements [`Debug`]. | |
| 6111 | * [`AtomicPtr`] implements [`Debug`]. | |
| 6112 | * [`Error`] trait objects [can be downcast to their concrete types][e] | |
| 6113 | in many common configurations, using the [`is`], [`downcast`], | |
| 6114 | [`downcast_ref`] and [`downcast_mut`] methods, similarly to the | |
| 6115 | [`Any`] trait. | |
| 6116 | * Searching for substrings now [employs the two-way algorithm][search] | |
| 6117 | instead of doing a naive search. This gives major speedups to a | |
| 6118 | number of methods, including [`contains`][sc], [`find`][sf], | |
| 6119 | [`rfind`][srf], [`split`][ss]. [`starts_with`][ssw] and | |
| 6120 | [`ends_with`][sew] are also faster. | |
| 6121 | * The performance of `PartialEq` for slices is [much faster][ps]. | |
| 6122 | * The [`Hash`] trait offers the default method, [`hash_slice`], which | |
| 6123 | is overridden and optimized by the implementations for scalars. | |
| 6124 | * The [`Hasher`] trait now has a number of specialized `write_*` | |
| 6125 | methods for primitive types, for efficiency. | |
| 6126 | * The I/O-specific error type, [`std::io::Error`][ie], gained a set of | |
| 6127 | methods for accessing the 'inner error', if any: [`get_ref`][iegr], | |
| 6128 | [`get_mut`][iegm], [`into_inner`][ieii]. As well, the implementation | |
| 6129 | of [`std::error::Error::cause`][iec] also delegates to the inner | |
| 6130 | error. | |
| 6131 | * [`process::Child`][pc] gained the [`id`] method, which returns a | |
| 6132 | `u32` representing the platform-specific process identifier. | |
| 6133 | * The [`connect`] method on slices is deprecated, replaced by the new | |
| 6134 | [`join`] method (note that both of these are on the *unstable* | |
| 6135 | [`SliceConcatExt`] trait, but through the magic of the prelude are | |
| 6136 | available to stable code anyway). | |
| 6137 | * The [`Div`] operator is implemented for [`Wrapping`] types. | |
| 6138 | * [`DerefMut` is implemented for `String`][dms]. | |
| 6139 | * Performance of SipHash (the default hasher for `HashMap`) is | |
| 6140 | [better for long data][sh]. | |
| 6141 | * [`AtomicPtr`] implements [`Send`]. | |
| 6142 | * The [`read_to_end`] implementations for [`Stdin`] and [`File`] | |
| ff7c6d11 | 6143 | are now [specialized to use uninitialized buffers for increased |
| c1a9b12d SL |
6144 | performance][rte]. |
| 6145 | * Lifetime parameters of foreign functions [are now resolved | |
| 6146 | properly][f]. | |
| 6147 | ||
| 6148 | Misc | |
| 6149 | ---- | |
| 6150 | ||
| 6151 | * Rust can now, with some coercion, [produce programs that run on | |
| 6152 | Windows XP][xp], though XP is not considered a supported platform. | |
| 6153 | * Porting Rust on Windows from the GNU toolchain to MSVC continues | |
| 6154 | ([1][win1], [2][win2], [3][win3], [4][win4]). It is still not | |
| 6155 | recommended for use in 1.3, though should be fully-functional | |
| 6156 | in the [64-bit 1.4 beta][b14]. | |
| 6157 | * On Fedora-based systems installation will [properly configure the | |
| 6158 | dynamic linker][fl]. | |
| 6159 | * The compiler gained many new extended error descriptions, which can | |
| 6160 | be accessed with the `--explain` flag. | |
| 6161 | * The `dropck` pass, which checks that destructors can't access | |
| 6162 | destroyed values, [has been rewritten][dropck]. This fixes some | |
| 6163 | soundness holes, and as such will cause some previously-compiling | |
| 6164 | code to no longer build. | |
| 6165 | * `rustc` now uses [LLVM to write archive files where possible][ar]. | |
| 6166 | Eventually this will eliminate the compiler's dependency on the ar | |
| 6167 | utility. | |
| 6168 | * Rust has [preliminary support for i686 FreeBSD][fb] (it has long | |
| 6169 | supported FreeBSD on x86_64). | |
| 6170 | * The [`unused_mut`][lum], [`unconditional_recursion`][lur], | |
| 6171 | [`improper_ctypes`][lic], and [`negate_unsigned`][lnu] lints are | |
| 6172 | more strict. | |
| 6173 | * If landing pads are disabled (with `-Z no-landing-pads`), [`panic!` | |
| 6174 | will kill the process instead of leaking][nlp]. | |

| e9174d1e SL |
6251 | Version 1.2.0 (2015-08-07) |
| 6252 | ========================== | |
| 62682a34 SL |
6253 | |
| 6254 | * ~1200 changes, numerous bugfixes | |
| 6255 | ||
| 6256 | Highlights | |
| 6257 | ---------- | |
| 6258 | ||
| 6259 | * [Dynamically-sized-type coercions][dst] allow smart pointer types | |
| 6260 | like `Rc` to contain types without a fixed size, arrays and trait | |
| 6261 | objects, finally enabling use of `Rc<[T]>` and completing the | |
| 6262 | implementation of DST. | |
| 6263 | * [Parallel codegen][parcodegen] is now working again, which can | |
| 6264 | substantially speed up large builds in debug mode; It also gets | |
| 6265 | another ~33% speedup when bootstrapping on a 4 core machine (using 8 | |
| 6266 | jobs). It's not enabled by default, but will be "in the near | |
| 6267 | future". It can be activated with the `-C codegen-units=N` flag to | |
| 6268 | `rustc`. | |
| 6269 | * This is the first release with [experimental support for linking | |
| 6270 | with the MSVC linker and lib C on Windows (instead of using the GNU | |
| 6271 | variants via MinGW)][win]. It is yet recommended only for the most | |
| ff7c6d11 | 6272 | intrepid Rustaceans. |
| 62682a34 SL |
6273 | * Benchmark compilations are showing a 30% improvement in |
| 6274 | bootstrapping over 1.1. | |
| 6275 | ||
| 6276 | Breaking Changes | |
| 6277 | ---------------- | |
| 6278 | ||
| 6279 | * The [`to_uppercase`] and [`to_lowercase`] methods on `char` now do | |
| 6280 | unicode case mapping, which is a previously-planned change in | |
| 6281 | behavior and considered a bugfix. | |
| 6282 | * [`mem::align_of`] now specifies [the *minimum alignment* for | |
| 6283 | T][align], which is usually the alignment programs are interested | |
| 6284 | in, and the same value reported by clang's | |
| 6285 | `alignof`. [`mem::min_align_of`] is deprecated. This is not known to | |
| 6286 | break real code. | |
| 6287 | * [The `#[packed]` attribute is no longer silently accepted by the | |
| 6288 | compiler][packed]. This attribute did nothing and code that | |
| 6289 | mentioned it likely did not work as intended. | |
| 6290 | * Associated type defaults are [now behind the | |
| 6291 | `associated_type_defaults` feature gate][ad]. In 1.1 associated type | |
| 6292 | defaults *did not work*, but could be mentioned syntactically. As | |
| 6293 | such this breakage has minimal impact. | |
| 6294 | ||
| 6295 | Language | |
| 6296 | -------- | |
| 6297 | ||
| 6298 | * Patterns with `ref mut` now correctly invoke [`DerefMut`] when | |
| 8faf50e0 | 6299 | matching against dereferenceable values. |
| 62682a34 SL |
6300 | |
| 6301 | Libraries | |
| 6302 | --------- | |
| 6303 | ||
| 6304 | * The [`Extend`] trait, which grows a collection from an iterator, is | |
| 6305 | implemented over iterators of references, for `String`, `Vec`, | |
| 6306 | `LinkedList`, `VecDeque`, `EnumSet`, `BinaryHeap`, `VecMap`, | |
| 6307 | `BTreeSet` and `BTreeMap`. [RFC][extend-rfc]. | |
| 6308 | * The [`iter::once`] function returns an iterator that yields a single | |
| 6309 | element, and [`iter::empty`] returns an iterator that yields no | |
| 6310 | elements. | |
| 6311 | * The [`matches`] and [`rmatches`] methods on `str` return iterators | |
| 6312 | over substring matches. | |
| 6313 | * [`Cell`] and [`RefCell`] both implement `Eq`. | |
| 6314 | * A number of methods for wrapping arithmetic are added to the | |
| 6315 | integral types, [`wrapping_div`], [`wrapping_rem`], | |
| 6316 | [`wrapping_neg`], [`wrapping_shl`], [`wrapping_shr`]. These are in | |
| 6317 | addition to the existing [`wrapping_add`], [`wrapping_sub`], and | |
| 6318 | [`wrapping_mul`] methods, and alternatives to the [`Wrapping`] | |
| 6319 | type.. It is illegal for the default arithmetic operations in Rust | |
| 6320 | to overflow; the desire to wrap must be explicit. | |
| 6321 | * The `{:#?}` formatting specifier [displays the alternate, | |
| 6322 | pretty-printed][debugfmt] form of the `Debug` formatter. This | |
| 6323 | feature was actually introduced prior to 1.0 with little | |
| 6324 | fanfare. | |
| 6325 | * [`fmt::Formatter`] implements [`fmt::Write`], a `fmt`-specific trait | |
| 6326 | for writing data to formatted strings, similar to [`io::Write`]. | |
| 6327 | * [`fmt::Formatter`] adds 'debug builder' methods, [`debug_struct`], | |
| 6328 | [`debug_tuple`], [`debug_list`], [`debug_set`], [`debug_map`]. These | |
| 6329 | are used by code generators to emit implementations of [`Debug`]. | |
| 6330 | * `str` has new [`to_uppercase`][strup] and [`to_lowercase`][strlow] | |
| 6331 | methods that convert case, following Unicode case mapping. | |
| 6332 | * It is now easier to handle poisoned locks. The [`PoisonError`] | |
| 6333 | type, returned by failing lock operations, exposes `into_inner`, | |
| 6334 | `get_ref`, and `get_mut`, which all give access to the inner lock | |
| 6335 | guard, and allow the poisoned lock to continue to operate. The | |
| 6336 | `is_poisoned` method of [`RwLock`] and [`Mutex`] can poll for a | |
| 6337 | poisoned lock without attempting to take the lock. | |
| 6338 | * On Unix the [`FromRawFd`] trait is implemented for [`Stdio`], and | |
| 6339 | [`AsRawFd`] for [`ChildStdin`], [`ChildStdout`], [`ChildStderr`]. | |
| 6340 | On Windows the `FromRawHandle` trait is implemented for `Stdio`, | |
| 6341 | and `AsRawHandle` for `ChildStdin`, `ChildStdout`, | |
| 6342 | `ChildStderr`. | |
| 6343 | * [`io::ErrorKind`] has a new variant, `InvalidData`, which indicates | |
| 6344 | malformed input. | |
| 6345 | ||
| 6346 | Misc | |
| 6347 | ---- | |
| 6348 | ||
| 6349 | * `rustc` employs smarter heuristics for guessing at [typos]. | |
| 6350 | * `rustc` emits more efficient code for [no-op conversions between | |
| 6351 | unsafe pointers][nop]. | |
| 6352 | * Fat pointers are now [passed in pairs of immediate arguments][fat], | |
| 6353 | resulting in faster compile times and smaller code. | |

| e9174d1e | 6409 | Version 1.1.0 (2015-06-25) |
| d9579d0f AL |
6410 | ========================= |
| 6411 | ||
| 6412 | * ~850 changes, numerous bugfixes | |
| 6413 | ||
| 6414 | Highlights | |
| 6415 | ---------- | |
| 6416 | ||
| c1a9b12d | 6417 | * The [`std::fs` module has been expanded][fs] to expand the set of |
| d9579d0f AL |
6418 | functionality exposed: |
| 6419 | * `DirEntry` now supports optimizations like `file_type` and `metadata` which | |
| 6420 | don't incur a syscall on some platforms. | |
| 6421 | * A `symlink_metadata` function has been added. | |
| 6422 | * The `fs::Metadata` structure now lowers to its OS counterpart, providing | |
| 6423 | access to all underlying information. | |
| c1a9b12d SL |
6424 | * The compiler now contains extended explanations of many errors. When an error |
| 6425 | with an explanation occurs the compiler suggests using the `--explain` flag | |
| 6426 | to read the explanation. Error explanations are also [available online][err-index]. | |
| d9579d0f AL |
6427 | * Thanks to multiple [improvements][sk] to [type checking][pre], as |
| 6428 | well as other work, the time to bootstrap the compiler decreased by | |
| 6429 | 32%. | |
| 6430 | ||
| 6431 | Libraries | |
| 6432 | --------- | |
| 6433 | ||
| c1a9b12d | 6434 | * The [`str::split_whitespace`] method splits a string on unicode |
| d9579d0f AL |
6435 | whitespace boundaries. |
| 6436 | * On both Windows and Unix, new extension traits provide conversion of | |
| 6437 | I/O types to and from the underlying system handles. On Unix, these | |
| c1a9b12d | 6438 | traits are [`FromRawFd`] and [`AsRawFd`], on Windows `FromRawHandle` |
| d9579d0f AL |
6439 | and `AsRawHandle`. These are implemented for `File`, `TcpStream`, |
| 6440 | `TcpListener`, and `UpdSocket`. Further implementations for | |
| 6441 | `std::process` will be stabilized later. | |
| 6442 | * On Unix, [`std::os::unix::symlink`] creates symlinks. On | |
| 6443 | Windows, symlinks can be created with | |
| 6444 | `std::os::windows::symlink_dir` and | |
| 6445 | `std::os::windows::symlink_file`. | |
| 6446 | * The `mpsc::Receiver` type can now be converted into an iterator with | |
| 6447 | `into_iter` on the [`IntoIterator`] trait. | |
| 6448 | * `Ipv4Addr` can be created from `u32` with the `From<u32>` | |
| 6449 | implementation of the [`From`] trait. | |
| 6450 | * The `Debug` implementation for `RangeFull` [creates output that is | |
| 6451 | more consistent with other implementations][rf]. | |
| 6452 | * [`Debug` is implemented for `File`][file]. | |
| 6453 | * The `Default` implementation for `Arc` [no longer requires `Sync + | |
| 6454 | Send`][arc]. | |
| 6455 | * [The `Iterator` methods `count`, `nth`, and `last` have been | |
| 6456 | overridden for slices to have O(1) performance instead of O(n)][si]. | |
| 6457 | * Incorrect handling of paths on Windows has been improved in both the | |
| 6458 | compiler and the standard library. | |
| 6459 | * [`AtomicPtr` gained a `Default` implementation][ap]. | |
| 6460 | * In accordance with Rust's policy on arithmetic overflow `abs` now | |
| 6461 | [panics on overflow when debug assertions are enabled][abs]. | |
| 6462 | * The [`Cloned`] iterator, which was accidentally left unstable for | |
| 6463 | 1.0 [has been stabilized][c]. | |
| 6464 | * The [`Incoming`] iterator, which iterates over incoming TCP | |
| 6465 | connections, and which was accidentally unnamable in 1.0, [is now | |
| 6466 | properly exported][inc]. | |
| 6467 | * [`BinaryHeap`] no longer corrupts itself [when functions called by | |
| 6468 | `sift_up` or `sift_down` panic][bh]. | |
| 6469 | * The [`split_off`] method of `LinkedList` [no longer corrupts | |
| 6470 | the list in certain scenarios][ll]. | |
| 6471 | ||
| 6472 | Misc | |
| 6473 | ---- | |
| 6474 | ||
| 6475 | * Type checking performance [has improved notably][sk] with | |
| 6476 | [multiple improvements][pre]. | |
| 6477 | * The compiler [suggests code changes][ch] for more errors. | |
| 6478 | * rustc and it's build system have experimental support for [building | |
| 6479 | toolchains against MUSL][m] instead of glibc on Linux. | |
| 6480 | * The compiler defines the `target_env` cfg value, which is used for | |
| 6481 | distinguishing toolchains that are otherwise for the same | |
| 6482 | platform. Presently this is set to `gnu` for common GNU Linux | |
| 6483 | targets and for MinGW targets, and `musl` for MUSL Linux targets. | |
| 6484 | * The [`cargo rustc`][crc] command invokes a build with custom flags | |
| 6485 | to rustc. | |
| 6486 | * [Android executables are always position independent][pie]. | |
| 6487 | * [The `drop_with_repr_extern` lint warns about mixing `repr(C)` | |
| 6488 | with `Drop`][drop]. | |

| bd371182 | 6521 | ======================== |
| c34b1796 | 6522 | |
| bd371182 | 6523 | * ~1500 changes, numerous bugfixes |
| c34b1796 | 6524 | |
| bd371182 AL |
6525 | Highlights |
| 6526 | ---------- | |
| 6527 | ||
| 6528 | * The vast majority of the standard library is now `#[stable]`. It is | |
| 6529 | no longer possible to use unstable features with a stable build of | |
| 6530 | the compiler. | |
| 6531 | * Many popular crates on [crates.io] now work on the stable release | |
| 6532 | channel. | |
| 6533 | * Arithmetic on basic integer types now [checks for overflow in debug | |
| 6534 | builds][overflow]. | |
| 6535 | ||
| 6536 | Language | |
| 6537 | -------- | |
| 6538 | ||
| 6539 | * Several [restrictions have been added to trait coherence][coh] in | |
| 6540 | order to make it easier for upstream authors to change traits | |
| 62682a34 | 6541 | without breaking downstream code. |
| bd371182 AL |
6542 | * Digits of binary and octal literals are [lexed more eagerly][lex] to |
| 6543 | improve error messages and macro behavior. For example, `0b1234` is | |
| 6544 | now lexed as `0b1234` instead of two tokens, `0b1` and `234`. | |
| 62682a34 | 6545 | * Trait bounds [are always invariant][inv], eliminating the need for |
| bd371182 AL |
6546 | the `PhantomFn` and `MarkerTrait` lang items, which have been |
| 6547 | removed. | |
| 6548 | * ["-" is no longer a valid character in crate names][cr], the `extern crate | |
| 6549 | "foo" as bar` syntax has been replaced with `extern crate foo as | |
| 6550 | bar`, and Cargo now automatically translates "-" in *package* names | |
| 6551 | to underscore for the crate name. | |
| 6552 | * [Lifetime shadowing is an error][lt]. | |
| 6553 | * [`Send` no longer implies `'static`][send-rfc]. | |
| 6554 | * [UFCS now supports trait-less associated paths][moar-ufcs] like | |
| 6555 | `MyType::default()`. | |
| 6556 | * Primitive types [now have inherent methods][prim-inherent], | |
| 6557 | obviating the need for extension traits like `SliceExt`. | |
| 6558 | * Methods with `Self: Sized` in their `where` clause are [considered | |
| 6559 | object-safe][self-sized], allowing many extension traits like | |
| 6560 | `IteratorExt` to be merged into the traits they extended. | |
| 6561 | * You can now [refer to associated types][assoc-where] whose | |
| 6562 | corresponding trait bounds appear only in a `where` clause. | |
| 6563 | * The final bits of [OIBIT landed][oibit-final], meaning that traits | |
| 6564 | like `Send` and `Sync` are now library-defined. | |
| 6565 | * A [Reflect trait][reflect] was introduced, which means that | |
| 6566 | downcasting via the `Any` trait is effectively limited to concrete | |
| 6567 | types. This helps retain the potentially-important "parametricity" | |
| 6568 | property: generic code cannot behave differently for different type | |
| 6569 | arguments except in minor ways. | |
| 6570 | * The `unsafe_destructor` feature is now deprecated in favor of the | |
| 6571 | [new `dropck`][dropck]. This change is a major reduction in unsafe | |
| 6572 | code. | |
| c34b1796 | 6573 | |
| bd371182 AL |
6574 | Libraries |
| 6575 | --------- | |
| c34b1796 | 6576 | |
| bd371182 AL |
6577 | * The `thread_local` module [has been renamed to `std::thread`][th]. |
| 6578 | * The methods of `IteratorExt` [have been moved to the `Iterator` | |
| 6579 | trait itself][ie]. | |
| 6580 | * Several traits that implement Rust's conventions for type | |
| 6581 | conversions, `AsMut`, `AsRef`, `From`, and `Into` have been | |
| 6582 | [centralized in the `std::convert` module][con]. | |
| 6583 | * The `FromError` trait [was removed in favor of `From`][fe]. | |
| 6584 | * The basic sleep function [has moved to | |
| 6585 | `std::thread::sleep_ms`][slp]. | |
| 6586 | * The `splitn` function now takes an `n` parameter that represents the | |
| 6587 | number of items yielded by the returned iterator [instead of the | |
| 6588 | number of 'splits'][spl]. | |
| 6589 | * [On Unix, all file descriptors are `CLOEXEC` by default][clo]. | |
| 6590 | * [Derived implementations of `PartialOrd` now order enums according | |
| 6591 | to their explicitly-assigned discriminants][po]. | |
| 6592 | * [Methods for searching strings are generic over `Pattern`s][pat], | |
| 6593 | implemented presently by `&char`, `&str`, `FnMut(char) -> bool` and | |
| 6594 | some others. | |
| 6595 | * [In method resolution, object methods are resolved before inherent | |
| 6596 | methods][meth]. | |
| 6597 | * [`String::from_str` has been deprecated in favor of the `From` impl, | |
| 6598 | `String::from`][sf]. | |
| 6599 | * [`io::Error` implements `Sync`][ios]. | |
| 6600 | * [The `words` method on `&str` has been replaced with | |
| 6601 | `split_whitespace`][sw], to avoid answering the tricky question, 'what is | |
| 6602 | a word?' | |
| 6603 | * The new path and IO modules are complete and `#[stable]`. This | |
| 6604 | was the major library focus for this cycle. | |
| 6605 | * The path API was [revised][path-normalize] to normalize `.`, | |
| 6606 | adjusting the tradeoffs in favor of the most common usage. | |
| 6607 | * A large number of remaining APIs in `std` were also stabilized | |
| 6608 | during this cycle; about 75% of the non-deprecated API surface | |
| 6609 | is now stable. | |
| 6610 | * The new [string pattern API][string-pattern] landed, which makes | |
| 6611 | the string slice API much more internally consistent and flexible. | |
| 6612 | * A new set of [generic conversion traits][conversion] replaced | |
| 6613 | many existing ad hoc traits. | |
| 6614 | * Generic numeric traits were [completely removed][num-traits]. This | |
| 6615 | was made possible thanks to inherent methods for primitive types, | |
| 6616 | and the removal gives maximal flexibility for designing a numeric | |
| 6617 | hierarchy in the future. | |
| 6618 | * The `Fn` traits are now related via [inheritance][fn-inherit] | |
| 6619 | and provide ergonomic [blanket implementations][fn-blanket]. | |
| 6620 | * The `Index` and `IndexMut` traits were changed to | |
| 6621 | [take the index by value][index-value], enabling code like | |
| 6622 | `hash_map["string"]` to work. | |
| 6623 | * `Copy` now [inherits][copy-clone] from `Clone`, meaning that all | |
| 6624 | `Copy` data is known to be `Clone` as well. | |
| 6625 | ||
| 6626 | Misc | |
| 6627 | ---- | |
| 6628 | ||
| 6629 | * Many errors now have extended explanations that can be accessed with | |
| 6630 | the `--explain` flag to `rustc`. | |
| 6631 | * Many new examples have been added to the standard library | |
| 6632 | documentation. | |
| 6633 | * rustdoc has received a number of improvements focused on completion | |
| 6634 | and polish. | |
| 6635 | * Metadata was tuned, shrinking binaries [by 27%][metadata-shrink]. | |
| 6636 | * Much headway was made on ecosystem-wide CI, making it possible | |
| 6637 | to [compare builds for breakage][ci-compare]. | |

6682 | |
| 6683 | * ~1300 changes, numerous bugfixes | |
| 6684 | ||
| 6685 | * Highlights | |
| 6686 | ||
| 6687 | * The various I/O modules were [overhauled][io-rfc] to reduce | |
| 62682a34 | 6688 | unnecessary abstractions and provide better interoperation with |
| 85aaf69f SL |
6689 | the underlying platform. The old `io` module remains temporarily |
| 6690 | at `std::old_io`. | |
| 62682a34 | 6691 | * The standard library now [participates in feature gating][feat], |
| 85aaf69f SL |
6692 | so use of unstable libraries now requires a `#![feature(...)]` |
| 6693 | attribute. The impact of this change is [described on the | |
| 6694 | forum][feat-forum]. [RFC][feat-rfc]. | |
| 6695 | ||
| 6696 | * Language | |
| 6697 | ||
| 6698 | * `for` loops [now operate on the `IntoIterator` trait][into], | |
| 6699 | which eliminates the need to call `.iter()`, etc. to iterate | |
| 6700 | over collections. There are some new subtleties to remember | |
| 6701 | though regarding what sort of iterators various types yield, in | |
| 6702 | particular that `for foo in bar { }` yields values from a move | |
| 6703 | iterator, destroying the original collection. [RFC][into-rfc]. | |
| 6704 | * Objects now have [default lifetime bounds][obj], so you don't | |
| 6705 | have to write `Box<Trait+'static>` when you don't care about | |
| 6706 | storing references. [RFC][obj-rfc]. | |
| 6707 | * In types that implement `Drop`, [lifetimes must outlive the | |
| 6708 | value][drop]. This will soon make it possible to safely | |
| 6709 | implement `Drop` for types where `#[unsafe_destructor]` is now | |
| 6710 | required. Read the [gorgeous RFC][drop-rfc] for details. | |
| 6711 | * The fully qualified <T as Trait>::X syntax lets you set the Self | |
| 6712 | type for a trait method or associated type. [RFC][ufcs-rfc]. | |
| 6713 | * References to types that implement `Deref<U>` now [automatically | |
| 6714 | coerce to references][deref] to the dereferenced type `U`, | |
| 6715 | e.g. `&T where T: Deref<U>` automatically coerces to `&U`. This | |
| 6716 | should eliminate many unsightly uses of `&*`, as when converting | |
| 6717 | from references to vectors into references to | |
| 6718 | slices. [RFC][deref-rfc]. | |
| 6719 | * The explicit [closure kind syntax][close] (`|&:|`, `|&mut:|`, | |
| 6720 | `|:|`) is obsolete and closure kind is inferred from context. | |
| 6721 | * [`Self` is a keyword][Self]. | |
| 6722 | ||
| 6723 | * Libraries | |
| 6724 | ||
| 6725 | * The `Show` and `String` formatting traits [have been | |
| 6726 | renamed][fmt] to `Debug` and `Display` to more clearly reflect | |
| 6727 | their related purposes. Automatically getting a string | |
| 6728 | conversion to use with `format!("{:?}", something_to_debug)` is | |
| 6729 | now written `#[derive(Debug)]`. | |
| 6730 | * Abstract [OS-specific string types][osstr], `std::ff::{OsString, | |
| 6731 | OsStr}`, provide strings in platform-specific encodings for easier | |
| 6732 | interop with system APIs. [RFC][osstr-rfc]. | |
| c34b1796 | 6733 | * The `boxed::into_raw` and `Box::from_raw` functions [convert |
| 85aaf69f SL |
6734 | between `Box<T>` and `*mut T`][boxraw], a common pattern for |
| 6735 | creating raw pointers. | |
| 6736 | ||
| 6737 | * Tooling | |
| 6738 | ||
| 6739 | * Certain long error messages of the form 'expected foo found bar' | |
| 6740 | are now [split neatly across multiple | |
| 6741 | lines][multiline]. Examples in the PR. | |
| 6742 | * On Unix Rust can be [uninstalled][un] by running | |
| 6743 | `/usr/local/lib/rustlib/uninstall.sh`. | |
| 6744 | * The `#[rustc_on_unimplemented]` attribute, requiring the | |
| 6745 | 'on_unimplemented' feature, lets rustc [display custom error | |
| 6746 | messages when a trait is expected to be implemented for a type | |
| 6747 | but is not][onun]. | |
| 6748 | ||
| 6749 | * Misc | |
| 6750 | ||
| 6751 | * Rust is tested against a [LALR grammar][lalr], which parses | |
| 6752 | almost all the Rust files that rustc does. | |

| b039eaaf | 6779 | Version 1.0.0-alpha (2015-01-09) |
| 62682a34 | 6780 | ================================== |
| 1a4d82fc JJ |
6781 | |
| 6782 | * ~2400 changes, numerous bugfixes | |
| 6783 | ||
| 6784 | * Highlights | |
| 6785 | ||
| 6786 | * The language itself is considered feature complete for 1.0, | |
| 6787 | though there will be many usability improvements and bugfixes | |
| 6788 | before the final release. | |
| 6789 | * Nearly 50% of the public API surface of the standard library has | |
| 6790 | been declared 'stable'. Those interfaces are unlikely to change | |
| 6791 | before 1.0. | |
| 6792 | * The long-running debate over integer types has been | |
| 6793 | [settled][ints]: Rust will ship with types named `isize` and | |
| 6794 | `usize`, rather than `int` and `uint`, for pointer-sized | |
| 6795 | integers. Guidelines will be rolled out during the alpha cycle. | |
| 6796 | * Most crates that are not `std` have been moved out of the Rust | |
| 6797 | distribution into the Cargo ecosystem so they can evolve | |
| 6798 | separately and don't need to be stabilized as quickly, including | |
| 6799 | 'time', 'getopts', 'num', 'regex', and 'term'. | |
| 6800 | * Documentation continues to be expanded with more API coverage, more | |
| 6801 | examples, and more in-depth explanations. The guides have been | |
| 6802 | consolidated into [The Rust Programming Language][trpl]. | |
| 85aaf69f | 6803 | * "[Rust By Example][rbe]" is now maintained by the Rust team. |
| 1a4d82fc JJ |
6804 | * All official Rust binary installers now come with [Cargo], the |
| 6805 | Rust package manager. | |
| 6806 | ||
| 6807 | * Language | |
| 6808 | ||
| 6809 | * Closures have been [completely redesigned][unboxed] to be | |
| 6810 | implemented in terms of traits, can now be used as generic type | |
| 6811 | bounds and thus monomorphized and inlined, or via an opaque | |
| 6812 | pointer (boxed) as in the old system. The new system is often | |
| 6813 | referred to as 'unboxed' closures. | |
| 6814 | * Traits now support [associated types][assoc], allowing families | |
| 6815 | of related types to be defined together and used generically in | |
| 6816 | powerful ways. | |
| 6817 | * Enum variants are [namespaced by their type names][enum]. | |
| 6818 | * [`where` clauses][where] provide a more versatile and attractive | |
| 6819 | syntax for specifying generic bounds, though the previous syntax | |
| 6820 | remains valid. | |
| 6821 | * Rust again picks a [fallback][fb] (either i32 or f64) for uninferred | |
| 6822 | numeric types. | |
| 6823 | * Rust [no longer has a runtime][rt] of any description, and only | |
| 6824 | supports OS threads, not green threads. | |
| 6825 | * At long last, Rust has been overhauled for 'dynamically-sized | |
| 6826 | types' ([DST]), which integrates 'fat pointers' (object types, | |
| 6827 | arrays, and `str`) more deeply into the type system, making it | |
| 6828 | more consistent. | |
| 6829 | * Rust now has a general [range syntax][range], `i..j`, `i..`, and | |
| 6830 | `..j` that produce range types and which, when combined with the | |
| 6831 | `Index` operator and multidispatch, leads to a convenient slice | |
| 6832 | notation, `[i..j]`. | |
| 6833 | * The new range syntax revealed an ambiguity in the fixed-length | |
| 6834 | array syntax, so now fixed length arrays [are written `[T; | |
| 6835 | N]`][arrays]. | |
| 6836 | * The `Copy` trait is no longer implemented automatically. Unsafe | |
| 6837 | pointers no longer implement `Sync` and `Send` so types | |
| 6838 | containing them don't automatically either. `Sync` and `Send` | |
| 6839 | are now 'unsafe traits' so one can "forcibly" implement them via | |
| 6840 | `unsafe impl` if a type confirms to the requirements for them | |
| 6841 | even though the internals do not (e.g. structs containing unsafe | |
| 6842 | pointers like `Arc`). These changes are intended to prevent some | |
| 6843 | footguns and are collectively known as [opt-in built-in | |
| 6844 | traits][oibit] (though `Sync` and `Send` will soon become pure | |
| 6845 | library types unknown to the compiler). | |
| 6846 | * Operator traits now take their operands [by value][ops], and | |
| 6847 | comparison traits can use multidispatch to compare one type | |
| 6848 | against multiple other types, allowing e.g. `String` to be | |
| 6849 | compared with `&str`. | |
| 6850 | * `if let` and `while let` are no longer feature-gated. | |
| 6851 | * Rust has adopted a more [uniform syntax for escaping unicode | |
| 6852 | characters][unicode]. | |
| 6853 | * `macro_rules!` [has been declared stable][mac]. Though it is a | |
| 6854 | flawed system it is sufficiently popular that it must be usable | |
| 6855 | for 1.0. Effort has gone into [future-proofing][mac-future] it | |
| 6856 | in ways that will allow other macro systems to be developed in | |
| 6857 | parallel, and won't otherwise impact the evolution of the | |
| 6858 | language. | |
| 6859 | * The prelude has been [pared back significantly][prelude] such | |
| 6860 | that it is the minimum necessary to support the most pervasive | |
| 6861 | code patterns, and through [generalized where clauses][where] | |
| 6862 | many of the prelude extension traits have been consolidated. | |
| 6863 | * Rust's rudimentary reflection [has been removed][refl], as it | |
| 6864 | incurred too much code generation for little benefit. | |
| 6865 | * [Struct variants][structvars] are no longer feature-gated. | |
| 6866 | * Trait bounds can be [polymorphic over lifetimes][hrtb]. Also | |
| 6867 | known as 'higher-ranked trait bounds', this crucially allows | |
| 6868 | unboxed closures to work. | |
| 6869 | * Macros invocations surrounded by parens or square brackets and | |
| 6870 | not terminated by a semicolon are [parsed as | |
| 6871 | expressions][macros], which makes expressions like `vec![1i32, | |
| 6872 | 2, 3].len()` work as expected. | |
| 6873 | * Trait objects now implement their traits automatically, and | |
| 6874 | traits that can be coerced to objects now must be [object | |
| 6875 | safe][objsafe]. | |
| 6876 | * Automatically deriving traits is now done with `#[derive(...)]` | |
| 6877 | not `#[deriving(...)]` for [consistency with other naming | |
| 6878 | conventions][derive]. | |
| 6879 | * Importing the containing module or enum at the same time as | |
| 6880 | items or variants they contain is [now done with `self` instead | |
| 6881 | of `mod`][self], as in use `foo::{self, bar}` | |
| 6882 | * Glob imports are no longer feature-gated. | |
| 6883 | * The `box` operator and `box` patterns have been feature-gated | |
| 6884 | pending a redesign. For now unique boxes should be allocated | |
| 6885 | like other containers, with `Box::new`. | |
| 6886 | ||
| 6887 | * Libraries | |
| 6888 | ||
| 6889 | * A [series][coll1] of [efforts][coll2] to establish | |
| 6890 | [conventions][coll3] for collections types has resulted in API | |
| 6891 | improvements throughout the standard library. | |
| 6892 | * New [APIs for error handling][err] provide ergonomic interop | |
| 6893 | between error types, and [new conventions][err-conv] describe | |
| 6894 | more clearly the recommended error handling strategies in Rust. | |
| 6895 | * The `fail!` macro has been renamed to [`panic!`][panic] so that | |
| 6896 | it is easier to discuss failure in the context of error handling | |
| 6897 | without making clarifications as to whether you are referring to | |
| 6898 | the 'fail' macro or failure more generally. | |
| 6899 | * On Linux, `OsRng` prefers the new, more reliable `getrandom` | |
| 6900 | syscall when available. | |
| 6901 | * The 'serialize' crate has been renamed 'rustc-serialize' and | |
| 6902 | moved out of the distribution to Cargo. Although it is widely | |
| 62682a34 | 6903 | used now, it is expected to be superseded in the near future. |
| 1a4d82fc JJ |
6904 | * The `Show` formatter, typically implemented with |
| 6905 | `#[derive(Show)]` is [now requested with the `{:?}` | |
| 6906 | specifier][show] and is intended for use by all types, for uses | |
| 6907 | such as `println!` debugging. The new `String` formatter must be | |
| 6908 | implemented by hand, uses the `{}` specifier, and is intended | |
| 6909 | for full-fidelity conversions of things that can logically be | |
| 6910 | represented as strings. | |
| 6911 | ||
| 6912 | * Tooling | |
| 6913 | ||
| 6914 | * [Flexible target specification][flex] allows rustc's code | |
| 6915 | generation to be configured to support otherwise-unsupported | |
| 6916 | platforms. | |
| 6917 | * Rust comes with rust-gdb and rust-lldb scripts that launch their | |
| 6918 | respective debuggers with Rust-appropriate pretty-printing. | |
| 32a655c1 | 6919 | * The Windows installation of Rust is distributed with the |
| 1a4d82fc JJ |
6920 | MinGW components currently required to link binaries on that |
| 6921 | platform. | |
| 6922 | ||
| 6923 | * Misc | |
| 6924 | ||
| 6925 | * Nullable enum optimizations have been extended to more types so | |
| 6926 | that e.g. `Option<Vec<T>>` and `Option<String>` take up no more | |
| 6927 | space than the inner types themselves. | |
| 6928 | * Work has begun on supporting AArch64. | |

| b039eaaf | 6966 | Version 0.12.0 (2014-10-09) |
| 62682a34 | 6967 | ============================= |
| 1a4d82fc JJ |
6968 | |
| 6969 | * ~1900 changes, numerous bugfixes | |
| 6970 | ||
| 6971 | * Highlights | |
| 6972 | ||
| 6973 | * The introductory documentation (now called The Rust Guide) has | |
| 6974 | been completely rewritten, as have a number of supplementary | |
| 6975 | guides. | |
| 6976 | * Rust's package manager, Cargo, continues to improve and is | |
| 6977 | sometimes considered to be quite awesome. | |
| 6978 | * Many API's in `std` have been reviewed and updated for | |
| 6979 | consistency with the in-development Rust coding | |
| 6980 | guidelines. The standard library documentation tracks | |
| 6981 | stabilization progress. | |
| 6982 | * Minor libraries have been moved out-of-tree to the rust-lang org | |
| 6983 | on GitHub: uuid, semver, glob, num, hexfloat, fourcc. They can | |
| 6984 | be installed with Cargo. | |
| 6985 | * Lifetime elision allows lifetime annotations to be left off of | |
| 6986 | function declarations in many common scenarios. | |
| 6987 | * Rust now works on 64-bit Windows. | |
| 6988 | ||
| 6989 | * Language | |
| 6990 | * Indexing can be overloaded with the `Index` and `IndexMut` | |
| 6991 | traits. | |
| 6992 | * The `if let` construct takes a branch only if the `let` pattern | |
| 6993 | matches, currently behind the 'if_let' feature gate. | |
| 6994 | * 'where clauses', a more flexible syntax for specifying trait | |
| 6995 | bounds that is more aesthetic, have been added for traits and | |
| 6996 | free functions. Where clauses will in the future make it | |
| 6997 | possible to constrain associated types, which would be | |
| 6998 | impossible with the existing syntax. | |
| 6999 | * A new slicing syntax (e.g. `[0..4]`) has been introduced behind | |
| 7000 | the 'slicing_syntax' feature gate, and can be overloaded with | |
| 7001 | the `Slice` or `SliceMut` traits. | |
| 7002 | * The syntax for matching of sub-slices has been changed to use a | |
| 7003 | postfix `..` instead of prefix (.e.g. `[a, b, c..]`), for | |
| 7004 | consistency with other uses of `..` and to future-proof | |
| 7005 | potential additional uses of the syntax. | |
| 7006 | * The syntax for matching inclusive ranges in patterns has changed | |
| 7007 | from `0..3` to `0...4` to be consistent with the exclusive range | |
| 7008 | syntax for slicing. | |
| 7009 | * Matching of sub-slices in non-tail positions (e.g. `[a.., b, | |
| 7010 | c]`) has been put behind the 'advanced_slice_patterns' feature | |
| 7011 | gate and may be removed in the future. | |
| 7012 | * Components of tuples and tuple structs can be extracted using | |
| 7013 | the `value.0` syntax, currently behind the `tuple_indexing` | |
| 7014 | feature gate. | |
| 7015 | * The `#[crate_id]` attribute is no longer supported; versioning | |
| 7016 | is handled by the package manager. | |
| 7017 | * Renaming crate imports are now written `extern crate foo as bar` | |
| 7018 | instead of `extern crate bar = foo`. | |
| 7019 | * Renaming use statements are now written `use foo as bar` instead | |
| 7020 | of `use bar = foo`. | |
| 7021 | * `let` and `match` bindings and argument names in macros are now | |
| 7022 | hygienic. | |
| 7023 | * The new, more efficient, closure types ('unboxed closures') have | |
| 7024 | been added under a feature gate, 'unboxed_closures'. These will | |
| 7025 | soon replace the existing closure types, once higher-ranked | |
| 7026 | trait lifetimes are added to the language. | |
| 7027 | * `move` has been added as a keyword, for indicating closures | |
| 7028 | that capture by value. | |
| 7029 | * Mutation and assignment is no longer allowed in pattern guards. | |
| 7030 | * Generic structs and enums can now have trait bounds. | |
| 7031 | * The `Share` trait is now called `Sync` to free up the term | |
| 7032 | 'shared' to refer to 'shared reference' (the default reference | |
| 7033 | type. | |
| 7034 | * Dynamically-sized types have been mostly implemented, | |
| 7035 | unifying the behavior of fat-pointer types with the rest of the | |
| 7036 | type system. | |
| 7037 | * As part of dynamically-sized types, the `Sized` trait has been | |
| 7038 | introduced, which qualifying types implement by default, and | |
| 7039 | which type parameters expect by default. To specify that a type | |
| 7040 | parameter does not need to be sized, write `<Sized? T>`. Most | |
| 7041 | types are `Sized`, notable exceptions being unsized arrays | |
| 7042 | (`[T]`) and trait types. | |
| 7043 | * Closures can return `!`, as in `|| -> !` or `proc() -> !`. | |
| 7044 | * Lifetime bounds can now be applied to type parameters and object | |
| 7045 | types. | |
| 7046 | * The old, reference counted GC type, `Gc<T>` which was once | |
| 7047 | denoted by the `@` sigil, has finally been removed. GC will be | |
| 7048 | revisited in the future. | |
| 7049 | ||
| 7050 | * Libraries | |
| 7051 | * Library documentation has been improved for a number of modules. | |
| 7052 | * Bit-vectors, collections::bitv has been modernized. | |
| 7053 | * The url crate is deprecated in favor of | |
| 7054 | http://github.com/servo/rust-url, which can be installed with | |
| 7055 | Cargo. | |
| 7056 | * Most I/O stream types can be cloned and subsequently closed from | |
| 7057 | a different thread. | |
| 7058 | * A `std::time::Duration` type has been added for use in I/O | |
| 7059 | methods that rely on timers, as well as in the 'time' crate's | |
| 7060 | `Timespec` arithmetic. | |
| 7061 | * The runtime I/O abstraction layer that enabled the green thread | |
| 7062 | scheduler to do non-thread-blocking I/O has been removed, along | |
| 7063 | with the libuv-based implementation employed by the green thread | |
| 7064 | scheduler. This will greatly simplify the future I/O work. | |
| 7065 | * `collections::btree` has been rewritten to have a more | |
| 7066 | idiomatic and efficient design. | |
| 7067 | ||
| 7068 | * Tooling | |
| 7069 | * rustdoc output now indicates the stability levels of API's. | |
| 7070 | * The `--crate-name` flag can specify the name of the crate | |
| 7071 | being compiled, like `#[crate_name]`. | |
| 7072 | * The `-C metadata` specifies additional metadata to hash into | |
| 7073 | symbol names, and `-C extra-filename` specifies additional | |
| 7074 | information to put into the output filename, for use by the | |
| 7075 | package manager for versioning. | |
| 7076 | * debug info generation has continued to improve and should be | |
| 7077 | more reliable under both gdb and lldb. | |
| 7078 | * rustc has experimental support for compiling in parallel | |
| 7079 | using the `-C codegen-units` flag. | |
| 7080 | * rustc no longer encodes rpath information into binaries by | |
| 7081 | default. | |
| 7082 | ||
| 7083 | * Misc | |
| 7084 | * Stack usage has been optimized with LLVM lifetime annotations. | |
| 7085 | * Official Rust binaries on Linux are more compatible with older | |
| 7086 | kernels and distributions, built on CentOS 5.10. | |

| 62682a34 | 7090 | ========================== |
| 1a4d82fc JJ |
7091 | |
| 7092 | * ~1700 changes, numerous bugfixes | |
| 7093 | ||
| 7094 | * Language | |
| 7095 | * ~[T] has been removed from the language. This type is superseded by | |
| 7096 | the Vec<T> type. | |
| 7097 | * ~str has been removed from the language. This type is superseded by | |
| 7098 | the String type. | |
| 7099 | * ~T has been removed from the language. This type is superseded by the | |
| 7100 | Box<T> type. | |
| 7101 | * @T has been removed from the language. This type is superseded by the | |
| 7102 | standard library's std::gc::Gc<T> type. | |
| 7103 | * Struct fields are now all private by default. | |
| 7104 | * Vector indices and shift amounts are both required to be a `uint` | |
| 7105 | instead of any integral type. | |
| 7106 | * Byte character, byte string, and raw byte string literals are now all | |
| 7107 | supported by prefixing the normal literal with a `b`. | |
| 7108 | * Multiple ABIs are no longer allowed in an ABI string | |
| 7109 | * The syntax for lifetimes on closures/procedures has been tweaked | |
| 7110 | slightly: `<'a>|A, B|: 'b + K -> T` | |
| 7111 | * Floating point modulus has been removed from the language; however it | |
| 7112 | is still provided by a library implementation. | |
| 7113 | * Private enum variants are now disallowed. | |
| 7114 | * The `priv` keyword has been removed from the language. | |
| 7115 | * A closure can no longer be invoked through a &-pointer. | |
| 7116 | * The `use foo, bar, baz;` syntax has been removed from the language. | |
| 7117 | * The transmute intrinsic no longer works on type parameters. | |
| 7118 | * Statics now allow blocks/items in their definition. | |
| 7119 | * Trait bounds are separated from objects with + instead of : now. | |
| 7120 | * Objects can no longer be read while they are mutably borrowed. | |
| 7121 | * The address of a static is now marked as insignificant unless the | |
| 7122 | #[inline(never)] attribute is placed it. | |
| 7123 | * The #[unsafe_destructor] attribute is now behind a feature gate. | |
| 7124 | * Struct literals are no longer allowed in ambiguous positions such as | |
| 7125 | if, while, match, and for..in. | |
| 7126 | * Declaration of lang items and intrinsics are now feature-gated by | |
| 7127 | default. | |
| 7128 | * Integral literals no longer default to `int`, and floating point | |
| 7129 | literals no longer default to `f64`. Literals must be suffixed with an | |
| 7130 | appropriate type if inference cannot determine the type of the | |
| 7131 | literal. | |
| 7132 | * The Box<T> type is no longer implicitly borrowed to &mut T. | |
| 7133 | * Procedures are now required to not capture borrowed references. | |
| 7134 | ||
| 7135 | * Libraries | |
| 7136 | * The standard library is now a "facade" over a number of underlying | |
| 7137 | libraries. This means that development on the standard library should | |
| ff7c6d11 | 7138 | be speedier due to smaller crates, as well as a clearer line between |
| 1a4d82fc JJ |
7139 | all dependencies. |
| 7140 | * A new library, libcore, lives under the standard library's facade | |
| 7141 | which is Rust's "0-assumption" library, suitable for embedded and | |
| 7142 | kernel development for example. | |
| 7143 | * A regex crate has been added to the standard distribution. This crate | |
| 7144 | includes statically compiled regular expressions. | |
| 7145 | * The unwrap/unwrap_err methods on Result require a Show bound for | |
| 7146 | better error messages. | |
| 7147 | * The return types of the std::comm primitives have been centralized | |
| 7148 | around the Result type. | |
| 7149 | * A number of I/O primitives have gained the ability to time out their | |
| 7150 | operations. | |
| 7151 | * A number of I/O primitives have gained the ability to close their | |
| 7152 | reading/writing halves to cancel pending operations. | |
| 7153 | * Reverse iterator methods have been removed in favor of `rev()` on | |
| 7154 | their forward-iteration counterparts. | |
| 7155 | * A bitflags! macro has been added to enable easy interop with C and | |
| 7156 | management of bit flags. | |
| 7157 | * A debug_assert! macro is now provided which is disabled when | |
| 7158 | `--cfg ndebug` is passed to the compiler. | |
| 7159 | * A graphviz crate has been added for creating .dot files. | |
| 7160 | * The std::cast module has been migrated into std::mem. | |
| 7161 | * The std::local_data api has been migrated from freestanding functions | |
| 7162 | to being based on methods. | |
| 7163 | * The Pod trait has been renamed to Copy. | |
| 7164 | * jemalloc has been added as the default allocator for types. | |
| 7165 | * The API for allocating memory has been changed to use proper alignment | |
| 7166 | and sized deallocation | |
| 7167 | * Connecting a TcpStream or binding a TcpListener is now based on a | |
| 7168 | string address and a u16 port. This allows connecting to a hostname as | |
| 7169 | opposed to an IP. | |
| 7170 | * The Reader trait now contains a core method, read_at_least(), which | |
| 7171 | correctly handles many repeated 0-length reads. | |
| 7172 | * The process-spawning API is now centered around a builder-style | |
| 7173 | Command struct. | |
| 7174 | * The :? printing qualifier has been moved from the standard library to | |
| 7175 | an external libdebug crate. | |
| 7176 | * Eq/Ord have been renamed to PartialEq/PartialOrd. TotalEq/TotalOrd | |
| 7177 | have been renamed to Eq/Ord. | |
| 7178 | * The select/plural methods have been removed from format!. The escapes | |
| 7179 | for { and } have also changed from \{ and \} to {{ and }}, | |
| 7180 | respectively. | |
| 7181 | * The TaskBuilder API has been re-worked to be a true builder, and | |
| 7182 | extension traits for spawning native/green tasks have been added. | |
| 7183 | ||
| 7184 | * Tooling | |
| 7185 | * All breaking changes to the language or libraries now have their | |
| 7186 | commit message annotated with `[breaking-change]` to allow for easy | |
| 7187 | discovery of breaking changes. | |
| 7188 | * The compiler will now try to suggest how to annotate lifetimes if a | |
| 7189 | lifetime-related error occurs. | |
| 7190 | * Debug info continues to be improved greatly with general bug fixes and | |
| 7191 | better support for situations like link time optimization (LTO). | |
| 7192 | * Usage of syntax extensions when cross-compiling has been fixed. | |
| 7193 | * Functionality equivalent to GCC & Clang's -ffunction-sections, | |
| 7194 | -fdata-sections and --gc-sections has been enabled by default | |
| 7195 | * The compiler is now stricter about where it will load module files | |
| 7196 | from when a module is declared via `mod foo;`. | |
| 7197 | * The #[phase(syntax)] attribute has been renamed to #[phase(plugin)]. | |
| 7198 | Syntax extensions are now discovered via a "plugin registrar" type | |
| 7199 | which will be extended in the future to other various plugins. | |
| 7200 | * Lints have been restructured to allow for dynamically loadable lints. | |
| 7201 | * A number of rustdoc improvements: | |
| 7202 | * The HTML output has been visually redesigned. | |
| 7203 | * Markdown is now powered by hoedown instead of sundown. | |
| 7204 | * Searching heuristics have been greatly improved. | |
| 7205 | * The search index has been reduced in size by a great amount. | |
| 7206 | * Cross-crate documentation via `pub use` has been greatly improved. | |
| 7207 | * Primitive types are now hyperlinked and documented. | |
| 7208 | * Documentation has been moved from static.rust-lang.org/doc to | |
| 7209 | doc.rust-lang.org | |
| 7210 | * A new sandbox, play.rust-lang.org, is available for running and | |
| 7211 | sharing rust code examples on-line. | |
| 7212 | * Unused attributes are now more robustly warned about. | |
| 7213 | * The dead_code lint now warns about unused struct fields. | |
| 7214 | * Cross-compiling to iOS is now supported. | |
| 7215 | * Cross-compiling to mipsel is now supported. | |
| 7216 | * Stability attributes are now inherited by default and no longer apply | |
| 7217 | to intra-crate usage, only inter-crate usage. | |
| 7218 | * Error message related to non-exhaustive match expressions have been | |
| 7219 | greatly improved. | |

| b039eaaf | 7222 | Version 0.10 (2014-04-03) |
| 62682a34 | 7223 | ========================= |
| 1a4d82fc JJ |
7224 | |
| 7225 | * ~1500 changes, numerous bugfixes | |
| 7226 | ||
| 7227 | * Language | |
| 7228 | * A new RFC process is now in place for modifying the language. | |
| 7229 | * Patterns with `@`-pointers have been removed from the language. | |
| 7230 | * Patterns with unique vectors (`~[T]`) have been removed from the | |
| 7231 | language. | |
| 7232 | * Patterns with unique strings (`~str`) have been removed from the | |
| 7233 | language. | |
| 7234 | * `@str` has been removed from the language. | |
| 7235 | * `@[T]` has been removed from the language. | |
| 7236 | * `@self` has been removed from the language. | |
| 7237 | * `@Trait` has been removed from the language. | |
| 7238 | * Headers on `~` allocations which contain `@` boxes inside the type for | |
| 7239 | reference counting have been removed. | |
| 7240 | * The semantics around the lifetimes of temporary expressions have changed, | |
| 7241 | see #3511 and #11585 for more information. | |
| 7242 | * Cross-crate syntax extensions are now possible, but feature gated. See | |
| 7243 | #11151 for more information. This includes both `macro_rules!` macros as | |
| 7244 | well as syntax extensions such as `format!`. | |
| 7245 | * New lint modes have been added, and older ones have been turned on to be | |
| 7246 | warn-by-default. | |
| 7247 | * Unnecessary parentheses | |
| 7248 | * Uppercase statics | |
| 7249 | * Camel Case types | |
| 7250 | * Uppercase variables | |
| 7251 | * Publicly visible private types | |
| 7252 | * `#[deriving]` with raw pointers | |
| 7253 | * Unsafe functions can no longer be coerced to closures. | |
| 7254 | * Various obscure macros such as `log_syntax!` are now behind feature gates. | |
| 7255 | * The `#[simd]` attribute is now behind a feature gate. | |
| 7256 | * Visibility is no longer allowed on `extern crate` statements, and | |
| 7257 | unnecessary visibility (`priv`) is no longer allowed on `use` statements. | |
| 7258 | * Trailing commas are now allowed in argument lists and tuple patterns. | |
| 7259 | * The `do` keyword has been removed, it is now a reserved keyword. | |
| 7260 | * Default type parameters have been implemented, but are feature gated. | |
| 7261 | * Borrowed variables through captures in closures are now considered soundly. | |
| 7262 | * `extern mod` is now `extern crate` | |
| 7263 | * The `Freeze` trait has been removed. | |
| 7264 | * The `Share` trait has been added for types that can be shared among | |
| 7265 | threads. | |
| 7266 | * Labels in macros are now hygienic. | |
| 7267 | * Expression/statement macro invocations can be delimited with `{}` now. | |
| 7268 | * Treatment of types allowed in `static mut` locations has been tweaked. | |
| 7269 | * The `*` and `.` operators are now overloadable through the `Deref` and | |
| 7270 | `DerefMut` traits. | |
| 7271 | * `~Trait` and `proc` no longer have `Send` bounds by default. | |
| 7272 | * Partial type hints are now supported with the `_` type marker. | |
| 7273 | * An `Unsafe` type was introduced for interior mutability. It is now | |
| 7274 | considered undefined to transmute from `&T` to `&mut T` without using the | |
| 7275 | `Unsafe` type. | |
| 7276 | * The #[linkage] attribute was implemented for extern statics/functions. | |
| 7277 | * The inner attribute syntax has changed from `#[foo];` to `#![foo]`. | |
| 7278 | * `Pod` was renamed to `Copy`. | |
| 7279 | ||
| 7280 | * Libraries | |
| 7281 | * The `libextra` library has been removed. It has now been decomposed into | |
| 7282 | component libraries with smaller and more focused nuggets of | |
| 7283 | functionality. The full list of libraries can be found on the | |
| 7284 | documentation index page. | |
| 7285 | * std: `std::condition` has been removed. All I/O errors are now propagated | |
| 7286 | through the `Result` type. In order to assist with error handling, a | |
| 7287 | `try!` macro for unwrapping errors with an early return and a lint for | |
| 7288 | unused results has been added. See #12039 for more information. | |
| 7289 | * std: The `vec` module has been renamed to `slice`. | |
| 7290 | * std: A new vector type, `Vec<T>`, has been added in preparation for DST. | |
| 7291 | This will become the only growable vector in the future. | |
| 2c00a5a8 | 7292 | * std: `std::io` now has more public re-exports. Types such as `BufferedReader` |
| 1a4d82fc JJ |
7293 | are now found at `std::io::BufferedReader` instead of |
| 7294 | `std::io::buffered::BufferedReader`. | |
| 7295 | * std: `print` and `println` are no longer in the prelude, the `print!` and | |
| 7296 | `println!` macros are intended to be used instead. | |
| 7297 | * std: `Rc` now has a `Weak` pointer for breaking cycles, and it no longer | |
| 7298 | attempts to statically prevent cycles. | |
| 7299 | * std: The standard distribution is adopting the policy of pushing failure | |
| 7300 | to the user rather than failing in libraries. Many functions (such as | |
| 7301 | `slice::last()`) now return `Option<T>` instead of `T` + failing. | |
| 7302 | * std: `fmt::Default` has been renamed to `fmt::Show`, and it now has a new | |
| 7303 | deriving mode: `#[deriving(Show)]`. | |
| 7304 | * std: `ToStr` is now implemented for all types implementing `Show`. | |
| 7305 | * std: The formatting trait methods now take `&self` instead of `&T` | |
| 7306 | * std: The `invert()` method on iterators has been renamed to `rev()` | |
| 7307 | * std: `std::num` has seen a reduction in the genericity of its traits, | |
| 7308 | consolidating functionality into a few core traits. | |
| 7309 | * std: Backtraces are now printed on task failure if the environment | |
| 7310 | variable `RUST_BACKTRACE` is present. | |
| 7311 | * std: Naming conventions for iterators have been standardized. More details | |
| 7312 | can be found on the wiki's style guide. | |
| 7313 | * std: `eof()` has been removed from the `Reader` trait. Specific types may | |
| 7314 | still implement the function. | |
| 7315 | * std: Networking types are now cloneable to allow simultaneous reads/writes. | |
| 7316 | * std: `assert_approx_eq!` has been removed | |
| 7317 | * std: The `e` and `E` formatting specifiers for floats have been added to | |
| 7318 | print them in exponential notation. | |
| 7319 | * std: The `Times` trait has been removed | |
| 7320 | * std: Indications of variance and opting out of builtin bounds is done | |
| 7321 | through marker types in `std::kinds::marker` now | |
| 7322 | * std: `hash` has been rewritten, `IterBytes` has been removed, and | |
| 7323 | `#[deriving(Hash)]` is now possible. | |
| 7324 | * std: `SharedChan` has been removed, `Sender` is now cloneable. | |
| 7325 | * std: `Chan` and `Port` were renamed to `Sender` and `Receiver`. | |
| 7326 | * std: `Chan::new` is now `channel()`. | |
| 7327 | * std: A new synchronous channel type has been implemented. | |
| 7328 | * std: A `select!` macro is now provided for selecting over `Receiver`s. | |
| 7329 | * std: `hashmap` and `trie` have been moved to `libcollections` | |
| 7330 | * std: `run` has been rolled into `io::process` | |
| 7331 | * std: `assert_eq!` now uses `{}` instead of `{:?}` | |
| 7332 | * std: The equality and comparison traits have seen some reorganization. | |
| 7333 | * std: `rand` has moved to `librand`. | |
| 7334 | * std: `to_{lower,upper}case` has been implemented for `char`. | |
| 7335 | * std: Logging has been moved to `liblog`. | |
| 7336 | * collections: `HashMap` has been rewritten for higher performance and less | |
| 7337 | memory usage. | |
| 7338 | * native: The default runtime is now `libnative`. If `libgreen` is desired, | |
| 7339 | it can be booted manually. The runtime guide has more information and | |
| 7340 | examples. | |
| 7341 | * native: All I/O functionality except signals has been implemented. | |
| 7342 | * green: Task spawning with `libgreen` has been optimized with stack caching | |
| 7343 | and various trimming of code. | |
| 7344 | * green: Tasks spawned by `libgreen` now have an unmapped guard page. | |
| 7345 | * sync: The `extra::sync` module has been updated to modern rust (and moved | |
| 7346 | to the `sync` library), tweaking and improving various interfaces while | |
| 7347 | dropping redundant functionality. | |
| 7348 | * sync: A new `Barrier` type has been added to the `sync` library. | |
| 7349 | * sync: An efficient mutex for native and green tasks has been implemented. | |
| 7350 | * serialize: The `base64` module has seen some improvement. It treats | |
| 7351 | newlines better, has non-string error values, and has seen general | |
| 7352 | cleanup. | |
| 7353 | * fourcc: A `fourcc!` macro was introduced | |
| 7354 | * hexfloat: A `hexfloat!` macro was implemented for specifying floats via a | |
| 7355 | hexadecimal literal. | |
| 7356 | ||
| 7357 | * Tooling | |
| 7358 | * `rustpkg` has been deprecated and removed from the main repository. Its | |
| 7359 | replacement, `cargo`, is under development. | |
| 7360 | * Nightly builds of rust are now available | |
| 7361 | * The memory usage of rustc has been improved many times throughout this | |
| 7362 | release cycle. | |
| 7363 | * The build process supports disabling rpath support for the rustc binary | |
| 7364 | itself. | |
| 7365 | * Code generation has improved in some cases, giving more information to the | |
| 7366 | LLVM optimization passes to enable more extensive optimizations. | |
| 7367 | * Debuginfo compatibility with lldb on OSX has been restored. | |
| 7368 | * The master branch is now gated on an android bot, making building for | |
| 7369 | android much more reliable. | |
| 7370 | * Output flags have been centralized into one `--emit` flag. | |
| 7371 | * Crate type flags have been centralized into one `--crate-type` flag. | |
| 7372 | * Codegen flags have been consolidated behind a `-C` flag. | |
| 7373 | * Linking against outdated crates now has improved error messages. | |
| 7374 | * Error messages with lifetimes will often suggest how to annotate the | |
| 7375 | function to fix the error. | |
| 7376 | * Many more types are documented in the standard library, and new guides | |
| 7377 | were written. | |
| 7378 | * Many `rustdoc` improvements: | |
| 7379 | * code blocks are syntax highlighted. | |
| 7380 | * render standalone markdown files. | |
| 7381 | * the --test flag tests all code blocks by default. | |
| 7382 | * exported macros are displayed. | |

| 62682a34 | 7390 | ========================== |
| 1a4d82fc JJ |
7391 | |
| 7392 | * ~1800 changes, numerous bugfixes | |
| 7393 | ||
| 7394 | * Language | |
| 7395 | * The `float` type has been removed. Use `f32` or `f64` instead. | |
| 7396 | * A new facility for enabling experimental features (feature gating) has | |
| 7397 | been added, using the crate-level `#[feature(foo)]` attribute. | |
| 7398 | * Managed boxes (@) are now behind a feature gate | |
| 7399 | (`#[feature(managed_boxes)]`) in preparation for future removal. Use the | |
| 7400 | standard library's `Gc` or `Rc` types instead. | |
| 7401 | * `@mut` has been removed. Use `std::cell::{Cell, RefCell}` instead. | |
| 7402 | * Jumping back to the top of a loop is now done with `continue` instead of | |
| 7403 | `loop`. | |
| 7404 | * Strings can no longer be mutated through index assignment. | |
| 7405 | * Raw strings can be created via the basic `r"foo"` syntax or with matched | |
| 7406 | hash delimiters, as in `r###"foo"###`. | |
| 7407 | * `~fn` is now written `proc (args) -> retval { ... }` and may only be | |
| 7408 | called once. | |
| 7409 | * The `&fn` type is now written `|args| -> ret` to match the literal form. | |
| 7410 | * `@fn`s have been removed. | |
| 7411 | * `do` only works with procs in order to make it obvious what the cost | |
| 7412 | of `do` is. | |
| 7413 | * Single-element tuple-like structs can no longer be dereferenced to | |
| 7414 | obtain the inner value. A more comprehensive solution for overloading | |
| 7415 | the dereference operator will be provided in the future. | |
| 7416 | * The `#[link(...)]` attribute has been replaced with | |
| 7417 | `#[crate_id = "name#vers"]`. | |
| 7418 | * Empty `impl`s must be terminated with empty braces and may not be | |
| 7419 | terminated with a semicolon. | |
| 7420 | * Keywords are no longer allowed as lifetime names; the `self` lifetime | |
| 7421 | no longer has any special meaning. | |
| 7422 | * The old `fmt!` string formatting macro has been removed. | |
| 7423 | * `printf!` and `printfln!` (old-style formatting) removed in favor of | |
| 7424 | `print!` and `println!`. | |
| 7425 | * `mut` works in patterns now, as in `let (mut x, y) = (1, 2);`. | |
| 7426 | * The `extern mod foo (name = "bar")` syntax has been removed. Use | |
| 7427 | `extern mod foo = "bar"` instead. | |
| 7428 | * New reserved keywords: `alignof`, `offsetof`, `sizeof`. | |
| 7429 | * Macros can have attributes. | |
| 7430 | * Macros can expand to items with attributes. | |
| 7431 | * Macros can expand to multiple items. | |
| 7432 | * The `asm!` macro is feature-gated (`#[feature(asm)]`). | |
| 7433 | * Comments may be nested. | |
| 7434 | * Values automatically coerce to trait objects they implement, without | |
| 7435 | an explicit `as`. | |
| 7436 | * Enum discriminants are no longer an entire word but as small as needed to | |
| 7437 | contain all the variants. The `repr` attribute can be used to override | |
| 7438 | the discriminant size, as in `#[repr(int)]` for integer-sized, and | |
| 7439 | `#[repr(C)]` to match C enums. | |
| 7440 | * Non-string literals are not allowed in attributes (they never worked). | |
| 7441 | * The FFI now supports variadic functions. | |
| 7442 | * Octal numeric literals, as in `0o7777`. | |
| 7443 | * The `concat!` syntax extension performs compile-time string concatenation. | |
| 7444 | * The `#[fixed_stack_segment]` and `#[rust_stack]` attributes have been | |
| 7445 | removed as Rust no longer uses segmented stacks. | |
| 7446 | * Non-ascii identifiers are feature-gated (`#[feature(non_ascii_idents)]`). | |
| 7447 | * Ignoring all fields of an enum variant or tuple-struct is done with `..`, | |
| 7448 | not `*`; ignoring remaining fields of a struct is also done with `..`, | |
| 7449 | not `_`; ignoring a slice of a vector is done with `..`, not `.._`. | |
| 7450 | * `rustc` supports the "win64" calling convention via `extern "win64"`. | |
| 7451 | * `rustc` supports the "system" calling convention, which defaults to the | |
| 7452 | preferred convention for the target platform, "stdcall" on 32-bit Windows, | |
| 7453 | "C" elsewhere. | |
| 7454 | * The `type_overflow` lint (default: warn) checks literals for overflow. | |
| 7455 | * The `unsafe_block` lint (default: allow) checks for usage of `unsafe`. | |
| 7456 | * The `attribute_usage` lint (default: warn) warns about unknown | |
| 7457 | attributes. | |
| 7458 | * The `unknown_features` lint (default: warn) warns about unknown | |
| 7459 | feature gates. | |
| 7460 | * The `dead_code` lint (default: warn) checks for dead code. | |
| 7461 | * Rust libraries can be linked statically to one another | |
| 7462 | * `#[link_args]` is behind the `link_args` feature gate. | |
| 7463 | * Native libraries are now linked with `#[link(name = "foo")]` | |
| 7464 | * Native libraries can be statically linked to a rust crate | |
| 7465 | (`#[link(name = "foo", kind = "static")]`). | |
| 7466 | * Native OS X frameworks are now officially supported | |
| 7467 | (`#[link(name = "foo", kind = "framework")]`). | |
| 7468 | * The `#[thread_local]` attribute creates thread-local (not task-local) | |
| 7469 | variables. Currently behind the `thread_local` feature gate. | |
| 7470 | * The `return` keyword may be used in closures. | |
| 7471 | * Types that can be copied via a memcpy implement the `Pod` kind. | |
| 7472 | * The `cfg` attribute can now be used on struct fields and enum variants. | |
| 7473 | ||
| 7474 | * Libraries | |
| 7475 | * std: The `option` and `result` API's have been overhauled to make them | |
| 7476 | simpler, more consistent, and more composable. | |
| 7477 | * std: The entire `std::io` module has been replaced with one that is | |
| 7478 | more comprehensive and that properly interfaces with the underlying | |
| 7479 | scheduler. File, TCP, UDP, Unix sockets, pipes, and timers are all | |
| 7480 | implemented. | |
| 7481 | * std: `io::util` contains a number of useful implementations of | |
| 7482 | `Reader` and `Writer`, including `NullReader`, `NullWriter`, | |
| 7483 | `ZeroReader`, `TeeReader`. | |
| 7484 | * std: The reference counted pointer type `extra::rc` moved into std. | |
| 7485 | * std: The `Gc` type in the `gc` module will replace `@` (it is currently | |
| 7486 | just a wrapper around it). | |
| 7487 | * std: The `Either` type has been removed. | |
| 7488 | * std: `fmt::Default` can be implemented for any type to provide default | |
| 7489 | formatting to the `format!` macro, as in `format!("{}", myfoo)`. | |
| 7490 | * std: The `rand` API continues to be tweaked. | |
| 7491 | * std: The `rust_begin_unwind` function, useful for inserting breakpoints | |
| 7492 | on failure in gdb, is now named `rust_fail`. | |
| 7493 | * std: The `each_key` and `each_value` methods on `HashMap` have been | |
| 7494 | replaced by the `keys` and `values` iterators. | |
| 7495 | * std: Functions dealing with type size and alignment have moved from the | |
| 7496 | `sys` module to the `mem` module. | |
| 7497 | * std: The `path` module was written and API changed. | |
| 7498 | * std: `str::from_utf8` has been changed to cast instead of allocate. | |
| 7499 | * std: `starts_with` and `ends_with` methods added to vectors via the | |
| 7500 | `ImmutableEqVector` trait, which is in the prelude. | |
| 7501 | * std: Vectors can be indexed with the `get_opt` method, which returns `None` | |
| 7502 | if the index is out of bounds. | |
| 7503 | * std: Task failure no longer propagates between tasks, as the model was | |
| 7504 | complex, expensive, and incompatible with thread-based tasks. | |
| 7505 | * std: The `Any` type can be used for dynamic typing. | |
| 7506 | * std: `~Any` can be passed to the `fail!` macro and retrieved via | |
| 7507 | `task::try`. | |
| 7508 | * std: Methods that produce iterators generally do not have an `_iter` | |
| 7509 | suffix now. | |
| 7510 | * std: `cell::Cell` and `cell::RefCell` can be used to introduce mutability | |
| 7511 | roots (mutable fields, etc.). Use instead of e.g. `@mut`. | |
| 7512 | * std: `util::ignore` renamed to `prelude::drop`. | |
| 7513 | * std: Slices have `sort` and `sort_by` methods via the `MutableVector` | |
| 7514 | trait. | |
| 7515 | * std: `vec::raw` has seen a lot of cleanup and API changes. | |
| 7516 | * std: The standard library no longer includes any C++ code, and very | |
| 7517 | minimal C, eliminating the dependency on libstdc++. | |
| 7518 | * std: Runtime scheduling and I/O functionality has been factored out into | |
| 7519 | extensible interfaces and is now implemented by two different crates: | |
| 7520 | libnative, for native threading and I/O; and libgreen, for green threading | |
| 7521 | and I/O. This paves the way for using the standard library in more limited | |
| 7522 | embedded environments. | |
| 7523 | * std: The `comm` module has been rewritten to be much faster, have a | |
| 7524 | simpler, more consistent API, and to work for both native and green | |
| 7525 | threading. | |
| 7526 | * std: All libuv dependencies have been moved into the rustuv crate. | |
| 7527 | * native: New implementations of runtime scheduling on top of OS threads. | |
| 7528 | * native: New native implementations of TCP, UDP, file I/O, process spawning, | |
| 7529 | and other I/O. | |
| 7530 | * green: The green thread scheduler and message passing types are almost | |
| 7531 | entirely lock-free. | |
| 7532 | * extra: The `flatpipes` module had bitrotted and was removed. | |
| 7533 | * extra: All crypto functions have been removed and Rust now has a policy of | |
| 7534 | not reimplementing crypto in the standard library. In the future crypto | |
| 7535 | will be provided by external crates with bindings to established libraries. | |
| 7536 | * extra: `c_vec` has been modernized. | |
| 7537 | * extra: The `sort` module has been removed. Use the `sort` method on | |
| 7538 | mutable slices. | |
| 7539 | ||
| 7540 | * Tooling | |
| 7541 | * The `rust` and `rusti` commands have been removed, due to lack of | |
| 7542 | maintenance. | |
| 7543 | * `rustdoc` was completely rewritten. | |
| 7544 | * `rustdoc` can test code examples in documentation. | |
| 7545 | * `rustpkg` can test packages with the argument, 'test'. | |
| 7546 | * `rustpkg` supports arbitrary dependencies, including C libraries. | |
| 7547 | * `rustc`'s support for generating debug info is improved again. | |
| 7548 | * `rustc` has better error reporting for unbalanced delimiters. | |
| 7549 | * `rustc`'s JIT support was removed due to bitrot. | |
| 7550 | * Executables and static libraries can be built with LTO (-Z lto) | |
| 7551 | * `rustc` adds a `--dep-info` flag for communicating dependencies to | |
| 7552 | build tools. | |

| b039eaaf | 7555 | Version 0.8 (2013-09-26) |
| 62682a34 | 7556 | ============================ |
| 1a4d82fc JJ |
7557 | |
| 7558 | * ~2200 changes, numerous bugfixes | |
| 7559 | ||
| 7560 | * Language | |
| 7561 | * The `for` loop syntax has changed to work with the `Iterator` trait. | |
| 7562 | * At long last, unwinding works on Windows. | |
| 7563 | * Default methods are ready for use. | |
| 7564 | * Many trait inheritance bugs fixed. | |
| 7565 | * Owned and borrowed trait objects work more reliably. | |
| 7566 | * `copy` is no longer a keyword. It has been replaced by the `Clone` trait. | |
| 7567 | * rustc can omit emission of code for the `debug!` macro if it is passed | |
| 7568 | `--cfg ndebug` | |
| 7569 | * mod.rs is now "blessed". When loading `mod foo;`, rustc will now look | |
| 7570 | for foo.rs, then foo/mod.rs, and will generate an error when both are | |
| 7571 | present. | |
| 7572 | * Strings no longer contain trailing nulls. The new `std::c_str` module | |
| 7573 | provides new mechanisms for converting to C strings. | |
| 7574 | * The type of foreign functions is now `extern "C" fn` instead of `*u8'. | |
| 7575 | * The FFI has been overhauled such that foreign functions are called directly, | |
| 7576 | instead of through a stack-switching wrapper. | |
| 7577 | * Calling a foreign function must be done through a Rust function with the | |
| 7578 | `#[fixed_stack_segment]` attribute. | |
| 7579 | * The `externfn!` macro can be used to declare both a foreign function and | |
| 7580 | a `#[fixed_stack_segment]` wrapper at once. | |
| 7581 | * `pub` and `priv` modifiers on `extern` blocks are no longer parsed. | |
| 7582 | * `unsafe` is no longer allowed on extern fns - they are all unsafe. | |
| 7583 | * `priv` is disallowed everywhere except for struct fields and enum variants. | |
| 7584 | * `&T` (besides `&'static T`) is no longer allowed in `@T`. | |
| 7585 | * `ref` bindings in irrefutable patterns work correctly now. | |
| 7586 | * `char` is now prevented from containing invalid code points. | |
| 7587 | * Casting to `bool` is no longer allowed. | |
| 7588 | * `\0` is now accepted as an escape in chars and strings. | |
| 7589 | * `yield` is a reserved keyword. | |
| 7590 | * `typeof` is a reserved keyword. | |
| 7591 | * Crates may be imported by URL with `extern mod foo = "url";`. | |
| 7592 | * Explicit enum discriminants may be given as uints as in `enum E { V = 0u }` | |
| 7593 | * Static vectors can be initialized with repeating elements, | |
| 7594 | e.g. `static foo: [u8, .. 100]: [0, .. 100];`. | |
| 7595 | * Static structs can be initialized with functional record update, | |
| 7596 | e.g. `static foo: Foo = Foo { a: 5, .. bar };`. | |
| 7597 | * `cfg!` can be used to conditionally execute code based on the crate | |
| 7598 | configuration, similarly to `#[cfg(...)]`. | |
| 7599 | * The `unnecessary_qualification` lint detects unneeded module | |
| 7600 | prefixes (default: allow). | |
| 7601 | * Arithmetic operations have been implemented on the SIMD types in | |
| 7602 | `std::unstable::simd`. | |
| 7603 | * Exchange allocation headers were removed, reducing memory usage. | |
| 7604 | * `format!` implements a completely new, extensible, and higher-performance | |
| 7605 | string formatting system. It will replace `fmt!`. | |
| 7606 | * `print!` and `println!` write formatted strings (using the `format!` | |
| 7607 | extension) to stdout. | |
| 7608 | * `write!` and `writeln!` write formatted strings (using the `format!` | |
| 7609 | extension) to the new Writers in `std::rt::io`. | |
| 7610 | * The library section in which a function or static is placed may | |
| 7611 | be specified with `#[link_section = "..."]`. | |
| 7612 | * The `proto!` syntax extension for defining bounded message protocols | |
| 7613 | was removed. | |
| 7614 | * `macro_rules!` is hygienic for `let` declarations. | |
| 7615 | * The `#[export_name]` attribute specifies the name of a symbol. | |
| 7616 | * `unreachable!` can be used to indicate unreachable code, and fails | |
| 7617 | if executed. | |
| 7618 | ||
| 7619 | * Libraries | |
| 7620 | * std: Transitioned to the new runtime, written in Rust. | |
| 7621 | * std: Added an experimental I/O library, `rt::io`, based on the new | |
| 7622 | runtime. | |
| 7623 | * std: A new generic `range` function was added to the prelude, replacing | |
| 7624 | `uint::range` and friends. | |
| 7625 | * std: `range_rev` no longer exists. Since range is an iterator it can be | |
| 7626 | reversed with `range(lo, hi).invert()`. | |
| 7627 | * std: The `chain` method on option renamed to `and_then`; `unwrap_or_default` | |
| 7628 | renamed to `unwrap_or`. | |
| 7629 | * std: The `iterator` module was renamed to `iter`. | |
| 7630 | * std: Integral types now support the `checked_add`, `checked_sub`, and | |
| 7631 | `checked_mul` operations for detecting overflow. | |
| 7632 | * std: Many methods in `str`, `vec`, `option, `result` were renamed for | |
| 7633 | consistency. | |
| 7634 | * std: Methods are standardizing on conventions for casting methods: | |
| 7635 | `to_foo` for copying, `into_foo` for moving, `as_foo` for temporary | |
| 7636 | and cheap casts. | |
| 7637 | * std: The `CString` type in `c_str` provides new ways to convert to and | |
| 7638 | from C strings. | |
| 7639 | * std: `DoubleEndedIterator` can yield elements in two directions. | |
| 7640 | * std: The `mut_split` method on vectors partitions an `&mut [T]` into | |
| 7641 | two splices. | |
| 7642 | * std: `str::from_bytes` renamed to `str::from_utf8`. | |
| 7643 | * std: `pop_opt` and `shift_opt` methods added to vectors. | |
| 7644 | * std: The task-local data interface no longer uses @, and keys are | |
| 7645 | no longer function pointers. | |
| 7646 | * std: The `swap_unwrap` method of `Option` renamed to `take_unwrap`. | |
| 7647 | * std: Added `SharedPort` to `comm`. | |
| 7648 | * std: `Eq` has a default method for `ne`; only `eq` is required | |
| 7649 | in implementations. | |
| 7650 | * std: `Ord` has default methods for `le`, `gt` and `ge`; only `lt` | |
| 7651 | is required in implementations. | |
| 7652 | * std: `is_utf8` performance is improved, impacting many string functions. | |
| 7653 | * std: `os::MemoryMap` provides cross-platform mmap. | |
| 7654 | * std: `ptr::offset` is now unsafe, but also more optimized. Offsets that | |
| 7655 | are not 'in-bounds' are considered undefined. | |
| 7656 | * std: Many freestanding functions in `vec` removed in favor of methods. | |
| 7657 | * std: Many freestanding functions on scalar types removed in favor of | |
| 7658 | methods. | |
| 7659 | * std: Many options to task builders were removed since they don't make | |
| 7660 | sense in the new scheduler design. | |
| 7661 | * std: More containers implement `FromIterator` so can be created by the | |
| 7662 | `collect` method. | |
| 7663 | * std: More complete atomic types in `unstable::atomics`. | |
| 7664 | * std: `comm::PortSet` removed. | |
| 7665 | * std: Mutating methods in the `Set` and `Map` traits have been moved into | |
| 7666 | the `MutableSet` and `MutableMap` traits. `Container::is_empty`, | |
| 7667 | `Map::contains_key`, `MutableMap::insert`, and `MutableMap::remove` have | |
| 7668 | default implementations. | |
| 7669 | * std: Various `from_str` functions were removed in favor of a generic | |
| 7670 | `from_str` which is available in the prelude. | |
| 7671 | * std: `util::unreachable` removed in favor of the `unreachable!` macro. | |
| 7672 | * extra: `dlist`, the doubly-linked list was modernized. | |
| 7673 | * extra: Added a `hex` module with `ToHex` and `FromHex` traits. | |
| 7674 | * extra: Added `glob` module, replacing `std::os::glob`. | |
| 7675 | * extra: `rope` was removed. | |
| 7676 | * extra: `deque` was renamed to `ringbuf`. `RingBuf` implements `Deque`. | |
| 7677 | * extra: `net`, and `timer` were removed. The experimental replacements | |
| 7678 | are `std::rt::io::net` and `std::rt::io::timer`. | |
| 7679 | * extra: Iterators implemented for `SmallIntMap`. | |
| 7680 | * extra: Iterators implemented for `Bitv` and `BitvSet`. | |
| 7681 | * extra: `SmallIntSet` removed. Use `BitvSet`. | |
| 7682 | * extra: Performance of JSON parsing greatly improved. | |
| 7683 | * extra: `semver` updated to SemVer 2.0.0. | |
| 7684 | * extra: `term` handles more terminals correctly. | |
| 7685 | * extra: `dbg` module removed. | |
| 7686 | * extra: `par` module removed. | |
| 7687 | * extra: `future` was cleaned up, with some method renames. | |
| 7688 | * extra: Most free functions in `getopts` were converted to methods. | |
| 7689 | ||
| 7690 | * Other | |
| 7691 | * rustc's debug info generation (`-Z debug-info`) is greatly improved. | |
| 7692 | * rustc accepts `--target-cpu` to compile to a specific CPU architecture, | |
| 7693 | similarly to gcc's `--march` flag. | |
| 7694 | * rustc's performance compiling small crates is much better. | |
| 7695 | * rustpkg has received many improvements. | |
| 7696 | * rustpkg supports git tags as package IDs. | |
| 7697 | * rustpkg builds into target-specific directories so it can be used for | |
| 7698 | cross-compiling. | |
| 7699 | * The number of concurrent test tasks is controlled by the environment | |
| 7700 | variable RUST_TEST_TASKS. | |
| 7701 | * The test harness can now report metrics for benchmarks. | |
| 7702 | * All tools have man pages. | |
| 7703 | * Programs compiled with `--test` now support the `-h` and `--help` flags. | |
| 7704 | * The runtime uses jemalloc for allocations. | |
| 7705 | * Segmented stacks are temporarily disabled as part of the transition to | |
| 7706 | the new runtime. Stack overflows are possible! | |
| 7707 | * A new documentation backend, rustdoc_ng, is available for use. It is | |
| 7708 | still invoked through the normal `rustdoc` command. | |

7713 | |
| 7714 | * ~2000 changes, numerous bugfixes | |
| 7715 | ||
| 7716 | * Language | |
| 7717 | * `impl`s no longer accept a visibility qualifier. Put them on methods | |
| 7718 | instead. | |
| 7719 | * The borrow checker has been rewritten with flow-sensitivity, fixing | |
| 7720 | many bugs and inconveniences. | |
| 7721 | * The `self` parameter no longer implicitly means `&'self self`, | |
| 7722 | and can be explicitly marked with a lifetime. | |
| 7723 | * Overloadable compound operators (`+=`, etc.) have been temporarily | |
| 7724 | removed due to bugs. | |
| 7725 | * The `for` loop protocol now requires `for`-iterators to return `bool` | |
| 7726 | so they compose better. | |
| 7727 | * The `Durable` trait is replaced with the `'static` bounds. | |
| 7728 | * Trait default methods work more often. | |
| 7729 | * Structs with the `#[packed]` attribute have byte alignment and | |
| 7730 | no padding between fields. | |
| 7731 | * Type parameters bound by `Copy` must now be copied explicitly with | |
| 7732 | the `copy` keyword. | |
| 7733 | * It is now illegal to move out of a dereferenced unsafe pointer. | |
| 7734 | * `Option<~T>` is now represented as a nullable pointer. | |
| 7735 | * `@mut` does dynamic borrow checks correctly. | |
| 7736 | * The `main` function is only detected at the topmost level of the crate. | |
| 7737 | The `#[main]` attribute is still valid anywhere. | |
| 7738 | * Struct fields may no longer be mutable. Use inherited mutability. | |
| 7739 | * The `#[no_send]` attribute makes a type that would otherwise be | |
| 7740 | `Send`, not. | |
| 7741 | * The `#[no_freeze]` attribute makes a type that would otherwise be | |
| 7742 | `Freeze`, not. | |
| 7743 | * Unbounded recursion will abort the process after reaching the limit | |
| 7744 | specified by the `RUST_MAX_STACK` environment variable (default: 1GB). | |
| 7745 | * The `vecs_implicitly_copyable` lint mode has been removed. Vectors | |
| 7746 | are never implicitly copyable. | |
| 7747 | * `#[static_assert]` makes compile-time assertions about static bools. | |
| 7748 | * At long last, 'argument modes' no longer exist. | |
| 7749 | * The rarely used `use mod` statement no longer exists. | |
| 7750 | ||
| 7751 | * Syntax extensions | |
| 7752 | * `fail!` and `assert!` accept `~str`, `&'static str` or `fmt!`-style | |
| 7753 | argument list. | |
| 7754 | * `Encodable`, `Decodable`, `Ord`, `TotalOrd`, `TotalEq`, `DeepClone`, | |
| 7755 | `Rand`, `Zero` and `ToStr` can all be automatically derived with | |
| 7756 | `#[deriving(...)]`. | |
| 7757 | * The `bytes!` macro returns a vector of bytes for string, u8, char, | |
| 7758 | and unsuffixed integer literals. | |
| 7759 | ||
| 7760 | * Libraries | |
| 7761 | * The `core` crate was renamed to `std`. | |
| 7762 | * The `std` crate was renamed to `extra`. | |
| 7763 | * More and improved documentation. | |
| 7764 | * std: `iterator` module for external iterator objects. | |
| 7765 | * Many old-style (internal, higher-order function) iterators replaced by | |
| 7766 | implementations of `Iterator`. | |
| 7767 | * std: Many old internal vector and string iterators, | |
| 7768 | incl. `any`, `all`. removed. | |
| 7769 | * std: The `finalize` method of `Drop` renamed to `drop`. | |
| 7770 | * std: The `drop` method now takes `&mut self` instead of `&self`. | |
| 2c00a5a8 | 7771 | * std: The prelude no longer re-exports any modules, only types and traits. |
| 1a4d82fc JJ |
7772 | * std: Prelude additions: `print`, `println`, `FromStr`, `ApproxEq`, `Equiv`, |
| 7773 | `Iterator`, `IteratorUtil`, many numeric traits, many tuple traits. | |
| 7774 | * std: New numeric traits: `Fractional`, `Real`, `RealExt`, `Integer`, `Ratio`, | |
| 7775 | `Algebraic`, `Trigonometric`, `Exponential`, `Primitive`. | |
| 7776 | * std: Tuple traits and accessors defined for up to 12-tuples, e.g. | |
| 7777 | `(0, 1, 2).n2()` or `(0, 1, 2).n2_ref()`. | |
| 7778 | * std: Many types implement `Clone`. | |
| 7779 | * std: `path` type renamed to `Path`. | |
| 7780 | * std: `mut` module and `Mut` type removed. | |
| 7781 | * std: Many standalone functions removed in favor of methods and iterators | |
| 7782 | in `vec`, `str`. In the future methods will also work as functions. | |
| 7783 | * std: `reinterpret_cast` removed. Use `transmute`. | |
| 7784 | * std: ascii string handling in `std::ascii`. | |
| 7785 | * std: `Rand` is implemented for ~/@. | |

| b039eaaf | 7828 | Version 0.6 (2013-04-03) |
| 62682a34 | 7829 | ======================== |
| 1a4d82fc JJ |
7830 | |
| 7831 | * ~2100 changes, numerous bugfixes | |
| 7832 | ||
| 7833 | * Syntax changes | |
| 7834 | * The self type parameter in traits is now spelled `Self` | |
| 7835 | * The `self` parameter in trait and impl methods must now be explicitly | |
| 7836 | named (for example: `fn f(&self) { }`). Implicit self is deprecated. | |
| 7837 | * Static methods no longer require the `static` keyword and instead | |
| 7838 | are distinguished by the lack of a `self` parameter | |
| 7839 | * Replaced the `Durable` trait with the `'static` lifetime | |
| 7840 | * The old closure type syntax with the trailing sigil has been | |
| 7841 | removed in favor of the more consistent leading sigil | |
| 7842 | * `super` is a keyword, and may be prefixed to paths | |
| 7843 | * Trait bounds are separated with `+` instead of whitespace | |
| 7844 | * Traits are implemented with `impl Trait for Type` | |
| 7845 | instead of `impl Type: Trait` | |
| 7846 | * Lifetime syntax is now `&'l foo` instead of `&l/foo` | |
| 7847 | * The `export` keyword has finally been removed | |
| 7848 | * The `move` keyword has been removed (see "Semantic changes") | |
| 7849 | * The interior mutability qualifier on vectors, `[mut T]`, has been | |
| 7850 | removed. Use `&mut [T]`, etc. | |
| 7851 | * `mut` is no longer valid in `~mut T`. Use inherited mutability | |
| 7852 | * `fail` is no longer a keyword. Use `fail!()` | |
| 7853 | * `assert` is no longer a keyword. Use `assert!()` | |
| 7854 | * `log` is no longer a keyword. use `debug!`, etc. | |
| 7855 | * 1-tuples may be represented as `(T,)` | |
| 7856 | * Struct fields may no longer be `mut`. Use inherited mutability, | |
| 7857 | `@mut T`, `core::mut` or `core::cell` | |
| 7858 | * `extern mod { ... }` is no longer valid syntax for foreign | |
| 7859 | function modules. Use extern blocks: `extern { ... }` | |
| 7860 | * Newtype enums removed. Use tuple-structs. | |
| 7861 | * Trait implementations no longer support visibility modifiers | |
| 7862 | * Pattern matching over vectors improved and expanded | |
| 7863 | * `const` renamed to `static` to correspond to lifetime name, | |
| 7864 | and make room for future `static mut` unsafe mutable globals. | |
| 7865 | * Replaced `#[deriving_eq]` with `#[deriving(Eq)]`, etc. | |
| 7866 | * `Clone` implementations can be automatically generated with | |
| 7867 | `#[deriving(Clone)]` | |
| 7868 | * Casts to traits must use a pointer sigil, e.g. `@foo as @Bar` | |
| 7869 | instead of `foo as Bar`. | |
| 7870 | * Fixed length vector types are now written as `[int, .. 3]` | |
| 7871 | instead of `[int * 3]`. | |
| 7872 | * Fixed length vector types can express the length as a constant | |
| 7873 | expression. (ex: `[int, .. GL_BUFFER_SIZE - 2]`) | |
| 7874 | ||
| 7875 | * Semantic changes | |
| 7876 | * Types with owned pointers or custom destructors move by default, | |
| 7877 | eliminating the `move` keyword | |
| 7878 | * All foreign functions are considered unsafe | |
| 7879 | * &mut is now unaliasable | |
| 7880 | * Writes to borrowed @mut pointers are prevented dynamically | |
| 7881 | * () has size 0 | |
| 7882 | * The name of the main function can be customized using #[main] | |
| 7883 | * The default type of an inferred closure is &fn instead of @fn | |
| 7884 | * `use` statements may no longer be "chained" - they cannot import | |
| 7885 | identifiers imported by previous `use` statements | |
| 7886 | * `use` statements are crate relative, importing from the "top" | |
| 7887 | of the crate by default. Paths may be prefixed with `super::` | |
| 7888 | or `self::` to change the search behavior. | |
| 7889 | * Method visibility is inherited from the implementation declaration | |
| 7890 | * Structural records have been removed | |
| 7891 | * Many more types can be used in static items, including enums | |
| 7892 | 'static-lifetime pointers and vectors | |
| 7893 | * Pattern matching over vectors improved and expanded | |
| 7894 | * Typechecking of closure types has been overhauled to | |
| 7895 | improve inference and eliminate unsoundness | |
| 7896 | * Macros leave scope at the end of modules, unless that module is | |
| 7897 | tagged with #[macro_escape] | |
| 7898 | ||
| 7899 | * Libraries | |
| 7900 | * Added big integers to `std::bigint` | |
| 7901 | * Removed `core::oldcomm` module | |
| 7902 | * Added pipe-based `core::comm` module | |

| 7906 | * Containers reorganized around traits in `core::container` | |
| 7907 | * `core::dvec` removed, `~[T]` is a drop-in replacement | |
| 7908 | * `core::send_map` renamed to `core::hashmap` | |
| 7909 | * `std::map` removed; replaced with `core::hashmap` | |

| 7913 | * Set types added to `core::hashmap`, `core::trie` and `std::treemap` | |
| 7914 | * `Ord` split into `Ord` and `TotalOrd`. `Ord` is still used to | |
| 7915 | overload the comparison operators, whereas `TotalOrd` is used | |
| 7916 | by certain container types | |
