29 More information may be found in the [edition
30 guide](https://doc.rust-lang.org/nightly/edition-guide/rust-2021/index.html).
31 [#9800](https://github.com/rust-lang/cargo/pull/9800)
32- 🎉 Added the
33 [`rust-version`](https://doc.rust-lang.org/nightly/cargo/reference/manifest.html#the-rust-version-field)
34 field to `Cargo.toml` to specify the minimum supported Rust version, and the
35 `--ignore-rust-version` command line option to override it.
36 [#9732](https://github.com/rust-lang/cargo/pull/9732)
37- Added the `[env]` table to config files to specify environment variables to
38 set.
39 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#env)
40 [#9411](https://github.com/rust-lang/cargo/pull/9411)
41- `[patch]` tables may now be specified in config files.
42 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#patch)
43 [#9839](https://github.com/rust-lang/cargo/pull/9839)
44- `cargo doc` now supports the `--example` and `--examples` flags.
45 [#9808](https://github.com/rust-lang/cargo/pull/9808)
46- 🎉 Build scripts can now pass additional linker arguments for binaries or all
570107f8
EH
47 linkable targets. [docs](https://doc.rust-lang.org/nightly/cargo/reference/build-scripts.html#outputs-of-the-build-script)
48 [#9557](https://github.com/rust-lang/cargo/pull/9557)
49- Added support for the `-p` flag for `cargo publish` to publish a specific
50 package in a workspace. `cargo package` also now supports `-p` and
51 `--workspace`.
52 [#9559](https://github.com/rust-lang/cargo/pull/9559)
8fe9eca8
EH
53- Added documentation about third-party registries.
54 [#9830](https://github.com/rust-lang/cargo/pull/9830)
55- Added the `{sha256-checksum}` placeholder for URLs in a registry `config.json`.
56 [docs](https://doc.rust-lang.org/nightly/cargo/reference/registries.html#index-format)

60
61### Changed
62
63- Doc tests now support the `-q` flag to show terse test output.
64 [#9730](https://github.com/rust-lang/cargo/pull/9730)

66 [#9681](https://github.com/rust-lang/cargo/pull/9681)
67- Changed so that only `wasm32-unknown-emscripten` executables are built
68 without a hash in the filename. Previously it was all `wasm32` targets.
69 Additionally, all `apple` binaries are now built with a hash in the
70 filename. This allows multiple copies to be cached at once, and matches the
71 behavior on other platforms (except `msvc`).
72 [#9653](https://github.com/rust-lang/cargo/pull/9653)
8fe9eca8
EH

83- Changed `cargo fix --edition` to emit a warning when on the latest stable
84 edition when running on stable instead of generating an error.
85 [#9792](https://github.com/rust-lang/cargo/pull/9792)
86- `cargo install` will now determine all of the packages to install before
87 starting the installation, which should help with reporting errors without
88 partially installing.
89 [#9793](https://github.com/rust-lang/cargo/pull/9793)
90- The resolver report for `cargo fix --edition` now includes differences for
91 dev-dependencies.
92 [#9803](https://github.com/rust-lang/cargo/pull/9803)
93- `cargo fix` will now show better diagnostics for abnormal errors from `rustc`.
94 [#9799](https://github.com/rust-lang/cargo/pull/9799)

570107f8
EH
132- Build scripts now have access to the following environment variables:

144### Changed
145
146- If a build command does not match any targets when using the
147 `--all-targets`, `--bins`, `--tests`, `--examples`, or `--benches` flags, a
148 warning is now displayed to inform you that there were no matching targets.
149 [#9549](https://github.com/rust-lang/cargo/pull/9549)
150- The way `cargo init` detects whether or not existing source files represent
151 a binary or library has been changed to respect the command-line flags
152 instead of trying to guess which type it is.
153 [#9522](https://github.com/rust-lang/cargo/pull/9522)
570107f8
EH
154- Registry names are now displayed instead of registry URLs when possible.
155 [#9632](https://github.com/rust-lang/cargo/pull/9632)
156- Duplicate compiler diagnostics are no longer shown. This can often happen
157 with `cargo test` which builds multiple copies of the same code in parallel.
158 This also updates the warning summary to provide more context.
159 [#9675](https://github.com/rust-lang/cargo/pull/9675)
160- The output for warnings or errors is now improved to be leaner, cleaner, and
161 show more context.
162 [#9655](https://github.com/rust-lang/cargo/pull/9655)
163- Network send errors are now treated as "spurious" which means they will be retried.
164 [#9695](https://github.com/rust-lang/cargo/pull/9695)
165- Git keys (`branch`, `tag`, `rev`) on a non-git dependency are now an error.

167 [#9689](https://github.com/rust-lang/cargo/pull/9689)
168- Specifying a dependency without any keys is now an error.
169 [#9686](https://github.com/rust-lang/cargo/pull/9686)
170- The resolver now prefers to use `[patch]` table entries of dependencies when
171 possible.
172 [#9639](https://github.com/rust-lang/cargo/pull/9639)
173- Package name typo errors in dependencies are now displayed aligned with the
174 original to help make it easier to see the difference.
175 [#9665](https://github.com/rust-lang/cargo/pull/9665)
176- Windows platforms may now warn on environment variables that have the wrong case.
177 [#9654](https://github.com/rust-lang/cargo/pull/9654)
178- `features` used in a `[patch]` table now issues a warning, as they are ignored.
179 [#9666](https://github.com/rust-lang/cargo/pull/9666)
180- The `target` directory is now excluded from content indexing on Windows.
181 [#9635](https://github.com/rust-lang/cargo/pull/9635)

183 misnamed with a lowercase `c` to suggest the correct form.
184 [#9607](https://github.com/rust-lang/cargo/pull/9607)
185- Building `diesel` with the new resolver displays a compatibility notice.
186 [#9602](https://github.com/rust-lang/cargo/pull/9602)
187- Updated the `opener` dependency, which handles opening a web browser, which
188 includes several changes, such as new behavior when run on WSL, and using
189 the system `xdg-open` on Linux.
190 [#9583](https://github.com/rust-lang/cargo/pull/9583)

570107f8
EH
207- `cargo fix` now fixes each target serially instead of in parallel to avoid
208 problems with fixing the same file concurrently.
209 [#9677](https://github.com/rust-lang/cargo/pull/9677)
210- Changes to the target `linker` config value now trigger a rebuild.
211 [#9647](https://github.com/rust-lang/cargo/pull/9647)

266 version requirements is now rejected.
267 [#9508](https://github.com/rust-lang/cargo/pull/9508)
268- Mtime handling of `.crate` published packages has changed slightly to avoid

274- `cargo new` with fossil now places the ignore settings in the new repository
275 instead of using `fossil settings` to set them globally. This also includes
276 several other cleanups to make it more consistent with other VCS
277 configurations.

353 builds. Previously, in some situations, the hash only included the package
354 name and version. This fixes some issues, such as incremental builds with
355 split-debuginfo on macOS corrupting the incremental cache in some cases.

684- Added `--message-format plain` option to `cargo locate-project` to display
685 the project location without JSON to make it easier to use in a script.
686 [#8707](https://github.com/rust-lang/cargo/pull/8707)

755- "http" class git errors now trigger a retry.
756 [#8553](https://github.com/rust-lang/cargo/pull/8553)
757- git dependencies now override the `core.autocrlf` git configuration value to
758 ensure they behave consistently across platforms, particularly when
759 vendoring git dependencies on Windows.
760 [#8523](https://github.com/rust-lang/cargo/pull/8523)
761- If `Cargo.lock` needs to be updated, then it will be automatically
762 transitioned to the new V2 format. This format removes the `[metadata]`
763 table, and should be easier to merge changes in source control systems. This
764 format was introduced in 1.38, and made the default for new projects in
765 1.41.
766 [#8554](https://github.com/rust-lang/cargo/pull/8554)
767- Added preparation for support of git repositories with a non-"master"
768 default branch. Actual support will arrive in a future version. This
769 introduces some warnings:
770 - Warn if a git dependency does not specify a branch, and the default branch
771 on the repository is not "master". In the future, Cargo will fetch the
772 default branch. In this scenario, the branch should be explicitly
773 specified.
774 - Warn if a workspace has multiple dependencies to the same git repository,
775 one without a `branch` and one with `branch="master"`. Dependencies should
776 all use one form or the other.
777 [#8522](https://github.com/rust-lang/cargo/pull/8522)
778- Warnings are now issued if a `required-features` entry lists a feature that
779 does not exist.
780 [#7950](https://github.com/rust-lang/cargo/pull/7950)
781- Built-in aliases are now included in `cargo --list`.
782 [#8542](https://github.com/rust-lang/cargo/pull/8542)
783- `cargo install` with a specific version that has been yanked will now
784 display an error message that it has been yanked, instead of "could not
785 find".
786 [#8565](https://github.com/rust-lang/cargo/pull/8565)
787- `cargo publish` with a package that has the `publish` field set to a single
788 registry, and no `--registry` flag has been given, will now publish to that
789 registry instead of generating an error.

823- The `dl` key in `config.json` of a registry index now supports the

829 - `CARGO_CRATE_NAME`: The name of the crate being built.
830 - `CARGO_BIN_NAME`: The name of the executable binary (if this is a binary crate).
831 - `CARGO_PKG_LICENSE`: The `license` field from the manifest.

835 [#8387](https://github.com/rust-lang/cargo/pull/8387)
836- If the value for `readme` is not specified in `Cargo.toml`, it is now
837 automatically inferred from the existence of a file named `README`,
838 `README.md`, or `README.txt`. This can be suppressed by setting
839 `readme = false`.
840 [#8277](https://github.com/rust-lang/cargo/pull/8277)
841- `cargo install` now supports the `--index` flag to install directly from an index.
842 [#8344](https://github.com/rust-lang/cargo/pull/8344)
843- Added the `metadata` table to the `workspace` definition in `Cargo.toml`.
844 This can be used for arbitrary data similar to the `package.metadata` table.
845 [#8323](https://github.com/rust-lang/cargo/pull/8323)
846- Added the `--target-dir` flag to `cargo install` to set the target directory.
847 [#8391](https://github.com/rust-lang/cargo/pull/8391)
848- Changes to environment variables used by the
849 [`env!`](https://doc.rust-lang.org/std/macro.env.html) or
850 [`option_env!`](https://doc.rust-lang.org/std/macro.option_env.html) macros
851 are now automatically detected to trigger a rebuild.
852 [#8421](https://github.com/rust-lang/cargo/pull/8421)
853- The `target` directory now includes the `CACHEDIR.TAG` file which is used by
854 some tools to exclude the directory from backups.
855 [#8378](https://github.com/rust-lang/cargo/pull/8378)

859### Changed
860- A warning is now displayed if a git dependency includes a `#` fragment in
861 the URL. This was potentially confusing because Cargo itself displays git
862 URLs with this syntax, but it does not have any meaning outside of the
863 `Cargo.lock` file, and would not work properly.

865- Various optimizations and fixes for bitcode embedding and LTO.
866 [#8349](https://github.com/rust-lang/cargo/pull/8349)
867- Reduced the amount of data fetched for git dependencies. If Cargo knows the
868 branch or tag to fetch, it will now only fetch that branch or tag instead of
869 all branches and tags.
870 [#8363](https://github.com/rust-lang/cargo/pull/8363)
871- Enhanced git fetch error messages.
872 [#8409](https://github.com/rust-lang/cargo/pull/8409)

879 subsequent runs allowed it proceed.
880 [#8274](https://github.com/rust-lang/cargo/pull/8274)
881- Removed assertion that Windows dylibs must have a `.dll` extension. Some
882 custom JSON spec targets may change the extension.
883 [#8310](https://github.com/rust-lang/cargo/pull/8310)
884- Updated libgit2, which brings in a fix for zlib errors for some remote

887- Fixed the GitHub fast-path check for up-to-date git dependencies on
888 non-master branches.
889 [#8363](https://github.com/rust-lang/cargo/pull/8363)
890- Fixed issue when enabling a feature with `pkg/feature` syntax, and `pkg` is
891 an optional dependency, but also a dev-dependency, and the dev-dependency
892 appears before the optional normal dependency in the registry summary, then
893 the optional dependency would not get activated.
894 [#8395](https://github.com/rust-lang/cargo/pull/8395)

898- Fixed indentation of multi-line Cargo error messages.
899 [#8409](https://github.com/rust-lang/cargo/pull/8409)
900- Fixed issue where the automatic inclusion of the `--document-private-items`

902 command.
903 [#8449](https://github.com/rust-lang/cargo/pull/8449)

930 [#8121](https://github.com/rust-lang/cargo/pull/8121)
931- The `registry.index` config value is no longer allowed (it has been
932 deprecated for 4 years).
933 [#7973](https://github.com/rust-lang/cargo/pull/7973)
934- An error is generated if both `--index` and `--registry` are passed
935 (previously `--index` was silently ignored).
936 [#7973](https://github.com/rust-lang/cargo/pull/7973)
937- The `registry.token` config value is no longer used with the `--index` flag.
938 This is intended to avoid potentially leaking the crates.io token to another
939 registry.
940 [#7973](https://github.com/rust-lang/cargo/pull/7973)
941- Added a warning if `registry.token` is used with source replacement. It is
942 intended this will be an error in future versions.
943 [#7973](https://github.com/rust-lang/cargo/pull/7973)
944- Windows GNU targets now copy `.dll.a` import library files for DLL crate
945 types to the output directory.
946 [#8141](https://github.com/rust-lang/cargo/pull/8141)
3b3ca095
EH
947- Dylibs for all dependencies are now unconditionally copied to the output
948 directory. Some obscure scenarios can cause an old dylib to be referenced
949 between builds, and this ensures that all the latest copies are used.
950 [#8139](https://github.com/rust-lang/cargo/pull/8139)
2011649f
EH
951- `package.exclude` can now match directory names. If a directory is
952 specified, the entire directory will be excluded, and Cargo will not attempt
953 to inspect it further. Previously Cargo would try to check every file in the
954 directory which could cause problems if the directory contained unreadable
955 files.
956 [#8095](https://github.com/rust-lang/cargo/pull/8095)
957- When packaging with `cargo publish` or `cargo package`, Cargo can use git to
958 guide its decision on which files to include. Previously this git-based
959 logic required a `Cargo.toml` file to exist at the root of the repository.
960 This is no longer required, so Cargo will now use git-based guidance even if
961 there is not a `Cargo.toml` in the root of the repository.
962 [#8095](https://github.com/rust-lang/cargo/pull/8095)
963- While unpacking a crate on Windows, if it fails to write a file because the
964 file is a reserved Windows filename (like "aux.rs"), Cargo will display an
965 extra message to explain why it failed.
966 [#8136](https://github.com/rust-lang/cargo/pull/8136)
967- Failures to set mtime on files are now ignored. Some filesystems did not
968 support this.
969 [#8185](https://github.com/rust-lang/cargo/pull/8185)
970- Certain classes of git errors will now recommend enabling
971 `net.git-fetch-with-cli`.
972 [#8166](https://github.com/rust-lang/cargo/pull/8166)
973- When doing an LTO build, Cargo will now instruct rustc not to perform
974 codegen when possible. This may result in a faster build and use less disk
975 space. Additionally, for non-LTO builds, Cargo will instruct rustc to not
976 embed LLVM bitcode in libraries, which should decrease their size.
977 [#8192](https://github.com/rust-lang/cargo/pull/8192)
978 [#8226](https://github.com/rust-lang/cargo/pull/8226)
979 [#8254](https://github.com/rust-lang/cargo/pull/8254)
980- The implementation for `cargo clean -p` has been rewritten so that it can
981 more accurately remove the files for a specific package.
982 [#8210](https://github.com/rust-lang/cargo/pull/8210)
983- The way Cargo computes the outputs from a build has been rewritten to be
984 more complete and accurate. Newly tracked files will be displayed in JSON
985 messages, and may be uplifted to the output directory in some cases. Some of
986 the changes from this are:
987
988 - `.exp` export files on Windows MSVC dynamic libraries are now tracked.
989 - Proc-macros on Windows track import/export files.
990 - All targets (like tests, etc.) that generate separate debug files
991 (pdb/dSYM) are tracked.
992 - Added .map files for wasm32-unknown-emscripten.
993 - macOS dSYM directories are tracked for all dynamic libraries
994 (dylib/cdylib/proc-macro) and for build scripts.
995
996 There are a variety of other changes as a consequence of this:
997
998 - Binary examples on Windows MSVC with a hyphen will now show up twice in
999 the examples directory (`foo_bar.exe` and `foo-bar.exe`). Previously Cargo
1000 just renamed the file instead of hard-linking it.
1001 - Example libraries now follow the same rules for hyphen/underscore
1002 translation as normal libs (they will now use underscores).
1003
1004 [#8210](https://github.com/rust-lang/cargo/pull/8210)
1005- Cargo attempts to scrub any secrets from the debug log for HTTP debugging.
1006 [#8222](https://github.com/rust-lang/cargo/pull/8222)
1007- Context has been added to many of Cargo's filesystem operations, so that
1008 error messages now provide more information, such as the path that caused
1009 the problem.
1010 [#8232](https://github.com/rust-lang/cargo/pull/8232)
1011- Several commands now ignore the error if stdout or stderr is closed while it
1012 is running. For example `cargo install --list | grep -q cargo-fuzz` would
1013 previously sometimes panic because `grep -q` may close stdout before the
1014 command finishes. Regular builds continue to fail if stdout or stderr is
1015 closed, matching the behavior of many other build systems.
1016 [#8236](https://github.com/rust-lang/cargo/pull/8236)
1017- If `cargo install` is given an exact version, like `--version=1.2.3`, it
1018 will now avoid updating the index if that version is already installed, and
1019 exit quickly indicating it is already installed.
1020 [#8022](https://github.com/rust-lang/cargo/pull/8022)

1039- Fixed backtraces on macOS not showing filenames or line numbers. As a
1040 consequence of this, binary executables on apple targets do not include a
1041 hash in the filename in Cargo's cache. This means Cargo can only track one
1042 copy, so if you switch features or rustc versions, Cargo will need to
1043 rebuild the executable.

1346
1347### Added
1348- 🔥 Cargo now uses a new `Cargo.lock` file format. This new format should
1349 support easier merges in source control systems. Projects using the old
1350 format will continue to use the old format, only new `Cargo.lock` files will
1351 use the new format.
1352 [#7579](https://github.com/rust-lang/cargo/pull/7579)
1353- 🔥 `cargo install` will now upgrade already installed packages instead of
1354 failing.
1355 [#7560](https://github.com/rust-lang/cargo/pull/7560)
1356- 🔥 Profile overrides have been added. This allows overriding profiles for
1357 individual dependencies or build scripts. See [the
1358 documentation](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#overrides)
1359 for more.
1360 [#7591](https://github.com/rust-lang/cargo/pull/7591)

1368 [#7576](https://github.com/rust-lang/cargo/pull/7576)
1369- Added `kind` and `platform` for dependencies in `cargo metadata`.
1370 [#7132](https://github.com/rust-lang/cargo/pull/7132)
1371- The `OUT_DIR` value is now included in the `build-script-executed` JSON message.
1372 [#7622](https://github.com/rust-lang/cargo/pull/7622)

1380 [#7570](https://github.com/rust-lang/cargo/pull/7570)
1381- Ignore `cargo login` text from copy/paste in token.
1382 [#7588](https://github.com/rust-lang/cargo/pull/7588)

1388### Fixed
1389- Fix unused warnings for some keys in the `build` config section.
1390 [#7575](https://github.com/rust-lang/cargo/pull/7575)
1391- Linux: Don't panic when parsing `/proc/stat`.
1392 [#7580](https://github.com/rust-lang/cargo/pull/7580)

1418- Dependencies extracted into Cargo's cache no longer preserve mtimes to
1419 reduce syscall overhead.
1420 [#7465](https://github.com/rust-lang/cargo/pull/7465)
1421- Windows: EXE files no longer include a metadata hash in the filename.
1422 This helps with debuggers correlating the filename with the PDB file.
1423 [#7400](https://github.com/rust-lang/cargo/pull/7400)
1424- Wasm32: `.wasm` files are no longer treated as an "executable", allowing
1425 `cargo test` and `cargo run` to work properly with the generated `.js` file.
1426 [#7476](https://github.com/rust-lang/cargo/pull/7476)
1427- crates.io now supports SPDX 3.6 licenses.
1428 [#7481](https://github.com/rust-lang/cargo/pull/7481)
1429- Improved cyclic dependency error message.
1430 [#7470](https://github.com/rust-lang/cargo/pull/7470)
1431- Bare `cargo clean` no longer locks the package cache.
1432 [#7502](https://github.com/rust-lang/cargo/pull/7502)
1433- `cargo publish` now allows dev-dependencies without a version key to be
1434 published. A git or path-only dev-dependency will be removed from the
1435 package manifest before uploading.
1436 [#7333](https://github.com/rust-lang/cargo/pull/7333)

EH
1437- `--features` and `--no-default-features` in the root of a virtual workspace
1438 will now generate an error instead of being ignored.
1439 [#7507](https://github.com/rust-lang/cargo/pull/7507)
1440- Generated files (like `Cargo.toml` and `Cargo.lock`) in a package archive
1441 now have their timestamp set to the current time instead of the epoch.
1442 [#7523](https://github.com/rust-lang/cargo/pull/7523)
1443- The `-Z` flag parser is now more strict, rejecting more invalid syntax.

1445
1446### Fixed
1447- Fixed an issue where if a package had an `include` field, and `Cargo.lock`
1448 in `.gitignore`, and a binary or example target, and the `Cargo.lock` exists
1449 in the current project, it would fail to publish complaining the
1450 `Cargo.lock` was dirty.
1451 [#7448](https://github.com/rust-lang/cargo/pull/7448)
1452- Fixed a panic in a particular combination of `[patch]` entries.
1453 [#7452](https://github.com/rust-lang/cargo/pull/7452)

1505 uncommitted changes.
1506 [#7245](https://github.com/rust-lang/cargo/pull/7245)
1507- In a build script, `cargo:rustc-flags` now allows `-l` and `-L` flags
1508 without spaces.

1511 delete any installed binaries that are no longer present in the newly
1512 installed version.
1513 [#7246](https://github.com/rust-lang/cargo/pull/7246)
1514- A git dependency may now also specify a `version` key when published. The
1515 `git` value will be stripped from the uploaded crate, matching the behavior
1516 of `path` dependencies.

1518- The behavior of workspace default-members has changed. The default-members
1519 now only applies when running Cargo in the root of the workspace. Previously
1520 it would always apply regardless of which directory Cargo is running in.
1521 [#7270](https://github.com/rust-lang/cargo/pull/7270)
1522- libgit2 updated pulling in all upstream changes.
1523 [#7275](https://github.com/rust-lang/cargo/pull/7275)
1524- Bump `home` dependency for locating home directories.
1525 [#7277](https://github.com/rust-lang/cargo/pull/7277)

1528- SSL connect errors are now retried.
1529 [#7318](https://github.com/rust-lang/cargo/pull/7318)
1530- The jobserver has been changed to acquire N tokens (instead of N-1), and
1531 then immediately acquires the extra token. This was changed to accommodate
1532 the `cc` crate on Windows to allow it to release its implicit token.
1533 [#7344](https://github.com/rust-lang/cargo/pull/7344)
1534- The scheduling algorithm for choosing which crate to build next has been
1535 changed. It now chooses the crate with the greatest number of transitive
1536 crates waiting on it. Previously it used a maximum topological depth.
1537 [#7390](https://github.com/rust-lang/cargo/pull/7390)

1538- RUSTFLAGS are no longer incorporated in the metadata and filename hash,
1539 reversing the change from 1.33 that added it. This means that any change to

1550 [#7303](https://github.com/rust-lang/cargo/pull/7303)
1551- Fixed issue with custom target `.json` files where a substring of the name
1552 matches an unsupported crate type (like "bin").
1553 [#7363](https://github.com/rust-lang/cargo/issues/7363)
1554- Fixed issues with generating documentation for proc-macro crate types.
1555 [#7159](https://github.com/rust-lang/cargo/pull/7159)
1556- Fixed hang if Cargo panics within a build thread.
1557 [#7366](https://github.com/rust-lang/cargo/pull/7366)
1558- Fixed rebuild detection if a `build.rs` script issues different `rerun-if`
1559 directives between builds. Cargo was erroneously causing a rebuild after the
1560 change.
1561 [#7373](https://github.com/rust-lang/cargo/pull/7373)
1562- Properly handle canonical URLs for `[patch]` table entries, preventing
1563 the patch from working after the first time it is used.
1564 [#7368](https://github.com/rust-lang/cargo/pull/7368)
1565- Fixed an issue where integration tests were waiting for the package binary
1566 to finish building before starting their own build. They now may build
1567 concurrently.
1568 [#7394](https://github.com/rust-lang/cargo/pull/7394)
1569- Fixed accidental change in the previous release on how `--features a b` flag
1570 is interpreted, restoring the original behavior where this is interpreted as
1571 `--features a` along with the argument `b` passed to the command. To pass
1572 multiple features, use quotes around the features to pass multiple features
1573 like `--features "a b"`, or use commas, or use multiple `--features` flags.

9e9c5868
EH
1689- 🔥 The [`cargo
1690 vendor`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-vendor.html)
1691 command is now built-in to Cargo. This command may be used to create a local
1692 copy of the sources of all dependencies.
1693 [#6869](https://github.com/rust-lang/cargo/pull/6869)
1694- 🔥 The "publish lockfile" feature is now stable. This feature will
1695 automatically include the `Cargo.lock` file when a package is published if
1696 it contains a binary executable target. By default, Cargo will ignore
1697 `Cargo.lock` when installing a package. To force Cargo to use the
1698 `Cargo.lock` file included in the published package, use `cargo install
1699 --locked`. This may be useful to ensure that `cargo install` consistently
1700 reproduces the same result. It may also be useful when a semver-incompatible
1701 change is accidentally published to a dependency, providing a way to fall
1702 back to a version that is known to work.
1703 [#7026](https://github.com/rust-lang/cargo/pull/7026)
1704- 🔥 The `default-run` feature has been stabilized. This feature allows you to
1705 specify which binary executable to run by default with `cargo run` when a
1706 package includes multiple binaries. Set the `default-run` key in the
1707 `[package]` table in `Cargo.toml` to the name of the binary to use by
1708 default.

1711### Changed

1713 directories.
1714 [#6973](https://github.com/rust-lang/cargo/pull/6973)
9e9c5868
EH
1715- A warning is now issued if `cargo doc` generates duplicate outputs, which
1716 causes files to be randomly stomped on. This may happen for a variety of
1717 reasons (renamed dependencies, multiple versions of the same package,
1718 packages with renamed libraries, etc.). This is a known bug, which needs
1719 more work to handle correctly.
1720 [#6998](https://github.com/rust-lang/cargo/pull/6998)
1721- Enabling a dependency's feature with `--features foo/bar` will no longer
1722 compile the current crate with the `foo` feature if `foo` is not an optional
1723 dependency.
1724 [#7010](https://github.com/rust-lang/cargo/pull/7010)
1725- If `--remap-path-prefix` is passed via RUSTFLAGS, it will no longer affect
1726 the filename metadata hash.
1727 [#6966](https://github.com/rust-lang/cargo/pull/6966)
1728- libgit2 has been updated to 0.28.2, which Cargo uses to access git
1729 repositories. This brings in hundreds of changes and fixes since it was last
1730 updated in November.
1731 [#7018](https://github.com/rust-lang/cargo/pull/7018)
1732- Cargo now supports absolute paths in the dep-info files generated by rustc.
1733 This is laying the groundwork for [tracking
1734 binaries](https://github.com/rust-lang/rust/pull/61727), such as libstd, for
1735 rebuild detection. (Note: this contains a known bug.)

EH
1747- Don't fail if a read-only lock cannot be acquired in CARGO_HOME. This helps
1748 when CARGO_HOME doesn't exist, but `--locked` is used which means CARGO_HOME
1749 is not needed.
1750 [#7149](https://github.com/rust-lang/cargo/pull/7149)
1751- Reverted a change in 1.35 which released jobserver tokens when Cargo blocked
1752 on a lock file. It caused a deadlock in some situations.

1759 future runs can redisplay previous warnings.

1792 binaries without the metadata hash so that debuggers can find it.
1793 [#6891](https://github.com/rust-lang/cargo/pull/6891)

1800- ✨ Changed `RUST_LOG` environment variable to `CARGO_LOG` so that user code
1801 that uses the `log` crate will not display cargo's debug output.
1802 [#6918](https://github.com/rust-lang/cargo/pull/6918)
1803- `Cargo.toml` is now always included when packaging, even if it is not listed
1804 in `package.include`.
1805 [#6925](https://github.com/rust-lang/cargo/pull/6925)
1806- Package include/exclude values now use gitignore patterns instead of glob
1807 patterns. [#6924](https://github.com/rust-lang/cargo/pull/6924)

2035- When updating the crate graph, unrelated yanked crates were erroneously
2036 removed. They are now kept at their original version if possible. This was
2037 causing unrelated packages to be downgraded during `cargo update -p
2038 somecrate`. [#5702](https://github.com/rust-lang/cargo/issues/5702)

2055 finishes. Also, [#5919](https://github.com/rust-lang/cargo/pull/5919) was
