40 Fixed an edge case where the resolver would fail to handle a cyclical dev-dependency with a feature.
41 [#10103](https://github.com/rust-lang/cargo/pull/10103)
42 - Fixed `cargo clean -p` when the directory path contains glob characters.
43 [#10072](https://github.com/rust-lang/cargo/pull/10072)
44 - Fixed debug builds of `cargo` which could panic when downloading a crate
45 when the server has a redirect with a non-empty body.
46 [#10048](https://github.com/rust-lang/cargo/pull/10048)
50 - Make future-incompat-report output more user-friendly.

60 ## Cargo 1.57 (2021-12-02)
61 [18751dd3...rust-1.57.0](https://github.com/rust-lang/cargo/compare/18751dd3...rust-1.57.0)
65 - 🎉 Added custom named profiles. This also changes the `test` and `bench`
66 profiles to inherit their settings from `dev` and `release`, and Cargo will
67 now only use a single profile during a given command instead of using
68 different profiles for dependencies and cargo-targets.
69 [docs](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#custom-profiles)
70 [#9943](https://github.com/rust-lang/cargo/pull/9943)
71 - The `rev` option for a git dependency now supports git references that start
72 with `refs/`. An example where this can be used is to depend on a pull
73 request from a service like GitHub before it is merged.
74 [#9859](https://github.com/rust-lang/cargo/pull/9859)
75 - Added `path_in_vcs` field to the `.cargo_vcs_info.json` file.

77 [#9866](https://github.com/rust-lang/cargo/pull/9866)
81 - ❗ `RUSTFLAGS` is no longer set for build scripts. This change was made in
82 1.55, but the release notes did not highlight this change. Build scripts
83 should use `CARGO_ENCODED_RUSTFLAGS` instead. See the
84 [documentation](https://doc.rust-lang.org/nightly/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-build-scripts)
86 - The `cargo version` command now includes some extra information.

95 metadata (stuff after `+` in the version number).
96 [#9945](https://github.com/rust-lang/cargo/pull/9945)
97 - zsh completions now complete `--example` names.
98 [#9939](https://github.com/rust-lang/cargo/pull/9939)

103 - Reverted the change from 1.55 that triggered an error for dependency
104 specifications that did not include any fields.
105 [#9911](https://github.com/rust-lang/cargo/pull/9911)
109 - Removed a log message (from `CARGO_LOG`) that may leak tokens.
110 [#9873](https://github.com/rust-lang/cargo/pull/9873)
111 - `cargo fix` will now avoid writing fixes to the global registry cache.
112 [#9938](https://github.com/rust-lang/cargo/pull/9938)
113 - Fixed `-Z help` CLI option when used with a shorthand alias (b/c/r/d).
114 [#9933](https://github.com/rust-lang/cargo/pull/9933)

130 [`rust-version`](https://doc.rust-lang.org/nightly/cargo/reference/manifest.html#the-rust-version-field)
131 field to `Cargo.toml` to specify the minimum supported Rust version, and the
132 `--ignore-rust-version` command line option to override it.
133 [#9732](https://github.com/rust-lang/cargo/pull/9732)
134 - Added the `[env]` table to config files to specify environment variables to
136 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#env)
137 [#9411](https://github.com/rust-lang/cargo/pull/9411)
138 - `[patch]` tables may now be specified in config files.
139 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#patch)

145 [#9557](https://github.com/rust-lang/cargo/pull/9557)
146 - Added support for the `-p` flag for `cargo publish` to publish a specific
147 package in a workspace. `cargo package` also now supports `-p` and
149 [#9559](https://github.com/rust-lang/cargo/pull/9559)
150 - Added documentation about third-party registries.
151 [#9830](https://github.com/rust-lang/cargo/pull/9830)

156 [#9771](https://github.com/rust-lang/cargo/pull/9771)
160 - Doc tests now support the `-q` flag to show terse test output.
161 [#9730](https://github.com/rust-lang/cargo/pull/9730)
162 - `features` used in a `[replace]` table now issues a warning, as they are ignored.
163 [#9681](https://github.com/rust-lang/cargo/pull/9681)
164 - Changed so that only `wasm32-unknown-emscripten` executables are built
165 without a hash in the filename. Previously it was all `wasm32` targets.
166 Additionally, all `apple` binaries are now built with a hash in the
167 filename. This allows multiple copies to be cached at once, and matches the
168 behavior on other platforms (except `msvc`).
169 [#9653](https://github.com/rust-lang/cargo/pull/9653)
170 - `cargo new` now generates an example that doesn't generate a warning with

178 environment variable.
179 [#9831](https://github.com/rust-lang/cargo/pull/9831)
180 - Changed `cargo fix --edition` to emit a warning when on the latest stable
181 edition when running on stable instead of generating an error.
182 [#9792](https://github.com/rust-lang/cargo/pull/9792)
183 - `cargo install` will now determine all of the packages to install before
184 starting the installation, which should help with reporting errors without
185 partially installing.
186 [#9793](https://github.com/rust-lang/cargo/pull/9793)
187 - The resolver report for `cargo fix --edition` now includes differences for
189 [#9803](https://github.com/rust-lang/cargo/pull/9803)

191 [#9799](https://github.com/rust-lang/cargo/pull/9799)
192 - Entries in `cargo --list` are now deduplicated.
193 [#9773](https://github.com/rust-lang/cargo/pull/9773)

202 [#9818](https://github.com/rust-lang/cargo/pull/9818)
203 - Return an error instead of a stack overflow for command alias loops.
204 [#9791](https://github.com/rust-lang/cargo/pull/9791)
205 - Updated to curl 7.79.1, which will hopefully fix intermittent http2 errors.
206 [#9937](https://github.com/rust-lang/cargo/pull/9937)
210 - Added `[future-incompat-report]` config section.
211 [#9774](https://github.com/rust-lang/cargo/pull/9774)
212 - Fixed value-after-table error with custom named profiles.
213 [#9789](https://github.com/rust-lang/cargo/pull/9789)
214 - Added the `different-binary-name` feature to support specifying a
215 non-rust-identifier for a binary name.
216 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#different-binary-name)
217 [#9627](https://github.com/rust-lang/cargo/pull/9627)
218 - Added a profile option to select the codegen backend.
219 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#codegen-backend)
220 [#9118](https://github.com/rust-lang/cargo/pull/9118)
223 ## Cargo 1.55 (2021-09-09)

231 - ❗ Build scripts now have access to the following environment variables:
232 `RUSTC_WRAPPER`, `RUSTC_WORKSPACE_WRAPPER`, `CARGO_ENCODED_RUSTFLAGS`.
233 `RUSTFLAGS` is no longer set for build scripts; they should use
234 `CARGO_ENCODED_RUSTFLAGS` instead.
235 [docs](https://doc.rust-lang.org/nightly/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-build-scripts)

247 - If a build command does not match any targets when using the
248 `--all-targets`, `--bins`, `--tests`, `--examples`, or `--benches` flags, a
249 warning is now displayed to inform you that there were no matching targets.
250 [#9549](https://github.com/rust-lang/cargo/pull/9549)
251 - The way `cargo init` detects whether or not existing source files represent
252 a binary or library has been changed to respect the command-line flags
253 instead of trying to guess which type it is.
254 [#9522](https://github.com/rust-lang/cargo/pull/9522)
255 - Registry names are now displayed instead of registry URLs when possible.
256 [#9632](https://github.com/rust-lang/cargo/pull/9632)
257 - Duplicate compiler diagnostics are no longer shown. This can often happen
258 with `cargo test` which builds multiple copies of the same code in parallel.
259 This also updates the warning summary to provide more context.
260 [#9675](https://github.com/rust-lang/cargo/pull/9675)
261 - The output for warnings or errors is now improved to be leaner, cleaner, and
263 [#9655](https://github.com/rust-lang/cargo/pull/9655)
264 - Network send errors are now treated as "spurious" which means they will be retried.
265 [#9695](https://github.com/rust-lang/cargo/pull/9695)
266 - Git keys (`branch`, `tag`, `rev`) on a non-git dependency are now an error.
267 Additionally, specifying both `git` and `path` is now an error.
268 [#9689](https://github.com/rust-lang/cargo/pull/9689)
269 - Specifying a dependency without any keys is now an error.
270 [#9686](https://github.com/rust-lang/cargo/pull/9686)

273 [#9639](https://github.com/rust-lang/cargo/pull/9639)
274 - Package name typo errors in dependencies are now displayed aligned with the
275 original to help make it easier to see the difference.
276 [#9665](https://github.com/rust-lang/cargo/pull/9665)
277 - Windows platforms may now warn on environment variables that have the wrong case.
278 [#9654](https://github.com/rust-lang/cargo/pull/9654)

282 [#9635](https://github.com/rust-lang/cargo/pull/9635)
283 - When `Cargo.toml` is not found, the error message now detects if it was
284 misnamed with a lowercase `c` to suggest the correct form.

286 - Building `diesel` with the new resolver displays a compatibility notice.
287 [#9602](https://github.com/rust-lang/cargo/pull/9602)
288 - Updated the `opener` dependency, which handles opening a web browser, which
289 includes several changes, such as new behavior when run on WSL, and using
290 the system `xdg-open` on Linux.
291 [#9583](https://github.com/rust-lang/cargo/pull/9583)
292 - Updated to libcurl 7.78.

355 [#9473](https://github.com/rust-lang/cargo/pull/9473)
356 - Added `CARGO_TARGET_TMPDIR` environment variable set for integration tests &
357 benches. This provides a temporary or "scratch" directory in the `target`
358 directory for tests and benches to use.
359 [#9375](https://github.com/rust-lang/cargo/pull/9375)
363 - `--features` CLI flags now provide typo suggestions with the new feature resolver.
364 [#9420](https://github.com/rust-lang/cargo/pull/9420)
365 - Cargo now uses a new parser for SemVer versions. This should behave mostly
366 the same as before with some minor exceptions where invalid syntax for
367 version requirements is now rejected.
368 [#9508](https://github.com/rust-lang/cargo/pull/9508)
369 - Mtime handling of `.crate` published packages has changed slightly to avoid
370 mtime values of 0. This was causing problems with lldb which refused to read
372 [#9517](https://github.com/rust-lang/cargo/pull/9517)
373 - Improved performance of git status check in `cargo package`.
374 [#9478](https://github.com/rust-lang/cargo/pull/9478)
375 - `cargo new` with fossil now places the ignore settings in the new repository
376 instead of using `fossil settings` to set them globally. This also includes
377 several other cleanups to make it more consistent with other VCS
379 [#9469](https://github.com/rust-lang/cargo/pull/9469)
380 - `rustc-cdylib-link-arg` applying transitively displays a warning that this
381 was not intended, and may be an error in the future.

386 - Fixed `package.exclude` in `Cargo.toml` using inverted exclusions
387 (`!somefile`) when not in a git repository or when vendoring a dependency.
388 [#9186](https://github.com/rust-lang/cargo/pull/9186)
389 - Dep-info files now adjust build script `rerun-if-changed` paths to be

392 - Fixed a bug when with resolver = "1" non-virtual package was allowing
394 [#9437](https://github.com/rust-lang/cargo/pull/9437)
395 - Fixed an issue with the index cache mishandling versions that only
396 differed in build metadata (such as `110.0.0` and `110.0.0+1.1.0f`).
397 [#9476](https://github.com/rust-lang/cargo/pull/9476)
398 - Fixed `cargo install` with a semver metadata version.
399 [#9467](https://github.com/rust-lang/cargo/pull/9467)

405 future-incompatibilities`.
406 [#9438](https://github.com/rust-lang/cargo/pull/9438)
407 - Added a `[host]` table to the config files to be able to set build flags for
408 host target. Also added `target-applies-to-host` to control how the
409 `[target]` tables behave.
410 [#9322](https://github.com/rust-lang/cargo/pull/9322)
411 - Added some validation to build script `rustc-link-arg-*` instructions to
412 return an error if the target doesn't exist.
413 [#9523](https://github.com/rust-lang/cargo/pull/9523)
414 - Added `cargo:rustc-link-arg-bin` instruction for build scripts.

418 ## Cargo 1.53 (2021-06-17)
419 [90691f2b...rust-1.53.0](https://github.com/rust-lang/cargo/compare/90691f2b...rust-1.53.0)
424 - 🔥 Cargo now supports git repositories where the default `HEAD` branch is not
425 "master". This also includes a switch to the version 3 `Cargo.lock` format
426 which can handle default branches correctly.
427 [#9133](https://github.com/rust-lang/cargo/pull/9133)
428 [#9397](https://github.com/rust-lang/cargo/pull/9397)
429 [#9384](https://github.com/rust-lang/cargo/pull/9384)
430 [#9392](https://github.com/rust-lang/cargo/pull/9392)
431 - 🔥 macOS targets now default to `unpacked` split-debuginfo.
432 [#9298](https://github.com/rust-lang/cargo/pull/9298)
433 - ❗ The `authors` field is no longer included in `Cargo.toml` for new
435 [#9282](https://github.com/rust-lang/cargo/pull/9282)
436 - `cargo update` may now work with the `--offline` flag.
437 [#9279](https://github.com/rust-lang/cargo/pull/9279)
438 - `cargo doc` will now erase the `doc` directory when switching between
439 different toolchain versions. There are shared, unversioned files (such as
440 the search index) that can become broken when using different versions.
441 [#8640](https://github.com/rust-lang/cargo/pull/8640)
442 [#9404](https://github.com/rust-lang/cargo/pull/9404)

451 rustdoc to clear out any stale files.
452 [#9419](https://github.com/rust-lang/cargo/pull/9419)
453 - Fixed the `-C metadata` value to always include all information for all
454 builds. Previously, in some situations, the hash only included the package
455 name and version. This fixes some issues, such as incremental builds with
456 split-debuginfo on macOS corrupting the incremental cache in some cases.
457 [#9418](https://github.com/rust-lang/cargo/pull/9418)
458 - Fixed man pages not working on Windows if `man` is in `PATH`.
459 [#9378](https://github.com/rust-lang/cargo/pull/9378)
460 - The `rustc` cache is now aware of `RUSTC_WRAPPER` and `RUSTC_WORKSPACE_WRAPPER`.
461 [#9348](https://github.com/rust-lang/cargo/pull/9348)
462 - Track the `CARGO` environment variable in the rebuild fingerprint if the
463 code uses `env!("CARGO")`.
464 [#9363](https://github.com/rust-lang/cargo/pull/9363)
467 - Fixed config includes not working.
468 [#9299](https://github.com/rust-lang/cargo/pull/9299)
469 - Emit note when `--future-incompat-report` had nothing to report.
470 [#9263](https://github.com/rust-lang/cargo/pull/9263)
471 - Error messages for nightly features flags (like `-Z` and `cargo-features`)
472 now provides more information.
473 [#9290](https://github.com/rust-lang/cargo/pull/9290)
474 - Added the ability to set the target for an individual package in `Cargo.toml`.
475 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#per-package-target)
476 [#9030](https://github.com/rust-lang/cargo/pull/9030)
477 - Fixed build-std updating the index on every build.
478 [#9393](https://github.com/rust-lang/cargo/pull/9393)
479 - `-Z help` now displays all the `-Z` options.
480 [#9369](https://github.com/rust-lang/cargo/pull/9369)
481 - Added `-Zallow-features` to specify which nightly features are allowed to be used.
482 [#9283](https://github.com/rust-lang/cargo/pull/9283)
483 - Added `cargo config` subcommand.
484 [#9302](https://github.com/rust-lang/cargo/pull/9302)
486 ## Cargo 1.52 (2021-05-06)

512 - Fixed publication of packages with metadata and resolver fields in `Cargo.toml`.
513 [#9300](https://github.com/rust-lang/cargo/pull/9300)
514 [#9304](https://github.com/rust-lang/cargo/pull/9304)
515 - Fixed logic for determining prefer-dynamic for a dylib which differed in a
516 workspace vs a single package.
517 [#9252](https://github.com/rust-lang/cargo/pull/9252)
518 - Fixed an issue where exclusive target-specific dependencies that overlapped
519 across dependency kinds (like regular and build-dependencies) would
520 incorrectly include the dependencies in both.
521 [#9255](https://github.com/rust-lang/cargo/pull/9255)
522 - Fixed panic with certain styles of Package IDs when passed to the `-p` flag.
523 [#9188](https://github.com/rust-lang/cargo/pull/9188)
524 - When running cargo with output not going to a TTY, and with the progress bar
525 and color force-enabled, the output will now correctly clear the progress
527 [#9231](https://github.com/rust-lang/cargo/pull/9231)
528 - Error instead of panic when JSON may contain non-utf8 paths.
529 [#9226](https://github.com/rust-lang/cargo/pull/9226)
530 - Fixed a hang that can happen on broken stderr.
531 [#9201](https://github.com/rust-lang/cargo/pull/9201)

544 dependencies that contain future-incompatible warnings.
545 [#8825](https://github.com/rust-lang/cargo/pull/8825)
546 - Added easier support for testing the 2021 edition.

563 - Changes to JSON spec targets will now trigger a rebuild.
564 [#9223](https://github.com/rust-lang/cargo/pull/9223)
566 ## Cargo 1.51 (2021-03-25)

572 [#9112](https://github.com/rust-lang/cargo/pull/9112)
573 - Added the `path` field to `cargo metadata` for the package dependencies list
574 to show the path for "path" dependencies.
575 [#8994](https://github.com/rust-lang/cargo/pull/8994)
576 - 🔥 Added a new feature resolver, and new CLI feature flag behavior. See the
577 new [features](https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2)
578 and [resolver](https://doc.rust-lang.org/nightly/cargo/reference/resolver.html#feature-resolver-version-2)
579 documentation for the `resolver = "2"` option. See the
580 [CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#command-line-feature-options)
581 and [resolver 2 CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#resolver-version-2-command-line-flags)
582 options for the new CLI behavior. And, finally, see
583 [RFC 2957](https://github.com/rust-lang/rfcs/blob/master/text/2957-cargo-features2.md)
584 for a detailed look at what has changed.
585 [#8997](https://github.com/rust-lang/cargo/pull/8997)
588 - `cargo install --locked` now emits a warning if `Cargo.lock` is not found.
589 [#9108](https://github.com/rust-lang/cargo/pull/9108)
590 - Unknown or ambiguous package IDs passed on the command-line now display
591 suggestions for the correct package ID.

593 - Slightly optimize `cargo vendor`
594 [#8937](https://github.com/rust-lang/cargo/pull/8937)
595 [#9131](https://github.com/rust-lang/cargo/pull/9131)
596 [#9132](https://github.com/rust-lang/cargo/pull/9132)
599 - Fixed environment variables and cfg settings emitted by a build script that
600 are set for `cargo test` and `cargo run` when the build script runs multiple
601 times during the same build session.
602 [#9122](https://github.com/rust-lang/cargo/pull/9122)
603 - Fixed a panic with `cargo doc` and the new feature resolver. This also
604 introduces some heuristics to try to avoid path collisions with `rustdoc` by
605 only documenting one variant of a package if there are multiple (such as
606 multiple versions, or the same package shared for host and target
608 [#9077](https://github.com/rust-lang/cargo/pull/9077)
609 - Fixed a bug in Cargo's cyclic dep graph detection that caused a stack
611 [#9075](https://github.com/rust-lang/cargo/pull/9075)
612 - Fixed build script `links` environment variables (`DEP_*`) not showing up
613 for testing packages in some cases.
614 [#9065](https://github.com/rust-lang/cargo/pull/9065)
615 - Fixed features being selected in a nondeterministic way for a specific
616 scenario when building an entire workspace with all targets with a
617 proc-macro in the workspace with `resolver="2"`.
618 [#9059](https://github.com/rust-lang/cargo/pull/9059)
619 - Fixed to use `http.proxy` setting in `~/.gitconfig`.
620 [#8986](https://github.com/rust-lang/cargo/pull/8986)
621 - Fixed --feature pkg/feat for V1 resolver for non-member.
622 [#9275](https://github.com/rust-lang/cargo/pull/9275)

629 [#9185](https://github.com/rust-lang/cargo/pull/9185)
630 [#9196](https://github.com/rust-lang/cargo/pull/9196)
631 - Fix panic with doc collision orphan.

633 [#9196](https://github.com/rust-lang/cargo/pull/9196)
636 - Removed the `publish-lockfile` unstable feature, it was stabilized without
637 the need for an explicit flag 1.5 years ago.
638 [#9092](https://github.com/rust-lang/cargo/pull/9092)
639 - Added better diagnostics, help messages, and documentation for nightly
640 features (such as those passed with the `-Z` flag, or specified with
641 `cargo-features` in `Cargo.toml`).
642 [#9092](https://github.com/rust-lang/cargo/pull/9092)
643 - Added support for Rust edition 2021.
644 [#8922](https://github.com/rust-lang/cargo/pull/8922)
645 - Added support for the `rust-version` field in project metadata.
646 [#8037](https://github.com/rust-lang/cargo/pull/8037)

655 - Added the `doc` field to `cargo metadata`, which indicates if a target is
657 [#8869](https://github.com/rust-lang/cargo/pull/8869)
658 - Added `RUSTC_WORKSPACE_WRAPPER`, an alternate RUSTC wrapper that only runs
659 for the local workspace packages, and caches its artifacts independently of
661 [#8976](https://github.com/rust-lang/cargo/pull/8976)
662 - Added `--workspace` to `cargo update` to update only the workspace members,
663 and not their dependencies. This is particularly useful if you update the
664 version in `Cargo.toml` and want to update `Cargo.lock` without running any
666 [#8725](https://github.com/rust-lang/cargo/pull/8725)
669 - `.crate` files uploaded to a registry are now built with reproducible
670 settings, so that the same `.crate` file created on different machines
672 [#8864](https://github.com/rust-lang/cargo/pull/8864)
673 - Git dependencies that specify more than one of `branch`, `tag`, or `rev` are
675 [#8984](https://github.com/rust-lang/cargo/pull/8984)
676 - The `rerun-if-changed` build script directive can now point to a directory,
677 in which case Cargo will check if any file in that directory changes.
678 [#8973](https://github.com/rust-lang/cargo/pull/8973)
679 - If Cargo cannot determine the username or email address, `cargo new` will no
680 longer fail, and instead create an empty authors list.
681 [#8912](https://github.com/rust-lang/cargo/pull/8912)
682 - The progress bar width has been reduced to provide more room to display the
683 crates currently being built.
684 [#8892](https://github.com/rust-lang/cargo/pull/8892)
685 - `cargo new` will now support `includeIf` directives in `.gitconfig` to match
686 the correct directory when determining the username and email address.
687 [#8886](https://github.com/rust-lang/cargo/pull/8886)
690 - Fixed `cargo metadata` and `cargo tree` to only download packages for the
692 [#8987](https://github.com/rust-lang/cargo/pull/8987)
693 - Updated libgit2, which brings in many fixes, particularly fixing a zlib
694 error that occasionally appeared on 32-bit systems.
695 [#8998](https://github.com/rust-lang/cargo/pull/8998)
696 - Fixed stack overflow with a circular dev-dependency that uses the `links`
698 [#8969](https://github.com/rust-lang/cargo/pull/8969)
699 - Fixed `cargo publish` failing on some filesystems, particularly 9p on WSL2.
700 [#8950](https://github.com/rust-lang/cargo/pull/8950)
703 - Allow `resolver="1"` to specify the original feature resolution behavior.
704 [#8857](https://github.com/rust-lang/cargo/pull/8857)
705 - Added `-Z extra-link-arg` which adds the `cargo:rustc-link-arg-bins`
706 and `cargo:rustc-link-arg` build script options.
707 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#extra-link-arg)
708 [#8441](https://github.com/rust-lang/cargo/pull/8441)
709 - Implemented external credential process support, and added `cargo logout`.
710 ([RFC 2730](https://github.com/rust-lang/rfcs/blob/master/text/2730-cargo-token-from-process.md))
711 ([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#credential-process))
712 [#8934](https://github.com/rust-lang/cargo/pull/8934)
713 - Fix panic with `-Zbuild-std` and no roots.
714 [#8942](https://github.com/rust-lang/cargo/pull/8942)
715 - Set docs.rs as the default extern-map for crates.io
716 [#8877](https://github.com/rust-lang/cargo/pull/8877)
718 ## Cargo 1.49 (2020-12-31)
719 [75615f8e...rust-1.49.0](https://github.com/rust-lang/cargo/compare/75615f8e...rust-1.49.0)
722 - Added `homepage` and `documentation` fields to `cargo metadata`.
723 [#8744](https://github.com/rust-lang/cargo/pull/8744)
724 - Added the `CARGO_PRIMARY_PACKAGE` environment variable which is set when
725 running `rustc` if the package is one of the "root" packages selected on the
727 [#8758](https://github.com/rust-lang/cargo/pull/8758)
728 - Added support for Unix-style glob patterns for package and target selection
729 flags on the command-line (such as `-p 'serde*'` or `--test '*'`).
730 [#8752](https://github.com/rust-lang/cargo/pull/8752)
733 - Computed LTO flags are now included in the filename metadata hash so that
734 changes in LTO settings will independently cache build artifacts instead of
735 overwriting previous ones. This prevents rebuilds in some situations such as
736 switching between `cargo build` and `cargo test` in some circumstances.
737 [#8755](https://github.com/rust-lang/cargo/pull/8755)
738 - `cargo tree` now displays `(proc-macro)` next to proc-macro packages.
739 [#8765](https://github.com/rust-lang/cargo/pull/8765)
740 - Added a warning that the allowed characters for a feature name have been
741 restricted to letters, digits, `_`, `-`, and `+` to accommodate future
742 syntax changes. This is still a superset of the allowed syntax on crates.io,
743 which requires ASCII. This is intended to be changed to an error in the
745 [#8814](https://github.com/rust-lang/cargo/pull/8814)
746 - `-p` without a value will now print a list of workspace package names.
747 [#8808](https://github.com/rust-lang/cargo/pull/8808)
748 - Add period to allowed feature name characters.
749 [#8932](https://github.com/rust-lang/cargo/pull/8932)
750 [#8943](https://github.com/rust-lang/cargo/pull/8943)
753 - Fixed building a library with both "dylib" and "rlib" crate types with LTO enabled.
754 [#8754](https://github.com/rust-lang/cargo/pull/8754)
755 - Fixed paths in Cargo's dep-info files.
756 [#8819](https://github.com/rust-lang/cargo/pull/8819)
757 - Fixed inconsistent source IDs in `cargo metadata` for git dependencies that
758 explicitly specify `branch="master"`.
759 [#8824](https://github.com/rust-lang/cargo/pull/8824)
760 - Fixed re-extracting dependencies which contained a `.cargo-ok` file.
761 [#8835](https://github.com/rust-lang/cargo/pull/8835)
764 - Fixed a panic with `cargo doc -Zfeatures=itarget` in some situations.
765 [#8777](https://github.com/rust-lang/cargo/pull/8777)
766 - New implementation for namespaced features, using the syntax `dep:serde`.
767 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#namespaced-features)
768 [#8799](https://github.com/rust-lang/cargo/pull/8799)
769 - Added support for "weak" dependency features, using the syntax
770 `dep_name?/feat_name`, which will enable a feature for a dependency without
771 also enabling the dependency.
772 [#8818](https://github.com/rust-lang/cargo/pull/8818)
773 - Fixed the new feature resolver downloading extra dependencies that weren't
775 [#8823](https://github.com/rust-lang/cargo/pull/8823)
777 ## Cargo 1.48 (2020-11-19)
778 [51b66125...rust-1.48.0](https://github.com/rust-lang/cargo/compare/51b66125...rust-1.48.0)
781 - Added `term.progress` configuration option to control when and how the
782 progress bar is displayed.
783 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#termprogresswhen)
784 [#8165](https://github.com/rust-lang/cargo/pull/8165)
785 - Added `--message-format plain` option to `cargo locate-project` to display
786 the project location without JSON to make it easier to use in a script.
787 [#8707](https://github.com/rust-lang/cargo/pull/8707)
788 - Added `--workspace` option to `cargo locate-project` to display the path to
789 the workspace manifest.
790 [#8712](https://github.com/rust-lang/cargo/pull/8712)
791 - A new contributor guide has been added for contributing to Cargo itself.
792 This is published at <https://rust-lang.github.io/cargo/contrib/>.
793 [#8715](https://github.com/rust-lang/cargo/pull/8715)
794 - Zsh `--target` completion will now complete with the built-in rustc targets.
795 [#8740](https://github.com/rust-lang/cargo/pull/8740)
800 - Fixed `cargo new` creating a fossil repository to properly ignore the `target` directory.
801 [#8671](https://github.com/rust-lang/cargo/pull/8671)
802 - Don't show warnings about the workspace in the current directory when using `cargo install`
804 [#8681](https://github.com/rust-lang/cargo/pull/8681)
805 - Automatically reinitialize the index when an "Object not found" error is
806 encountered in the git repository.
807 [#8735](https://github.com/rust-lang/cargo/pull/8735)
808 - Updated libgit2, which brings in several fixes for git repository handling.
809 [#8778](https://github.com/rust-lang/cargo/pull/8778)
810 [#8780](https://github.com/rust-lang/cargo/pull/8780)
813 - Fixed `cargo install` so that it will ignore the `[unstable]` table in local config files.
814 [#8656](https://github.com/rust-lang/cargo/pull/8656)
815 - Fixed nondeterministic behavior of the new feature resolver.
816 [#8701](https://github.com/rust-lang/cargo/pull/8701)
817 - Fixed running `cargo test` on a proc-macro with the new feature resolver
818 under a specific combination of circumstances.
819 [#8742](https://github.com/rust-lang/cargo/pull/8742)
821 ## Cargo 1.47 (2020-10-08)
822 [4f74d9b2...rust-1.47.0](https://github.com/rust-lang/cargo/compare/4f74d9b2...rust-1.47.0)
825 - `cargo doc` will now include the package's version in the left sidebar.
826 [#8509](https://github.com/rust-lang/cargo/pull/8509)
827 - Added the `test` field to `cargo metadata` targets.
828 [#8478](https://github.com/rust-lang/cargo/pull/8478)
829 - Cargo's man pages are now displayed via the `cargo help` command (such as
831 [#8456](https://github.com/rust-lang/cargo/pull/8456)
832 [#8577](https://github.com/rust-lang/cargo/pull/8577)
833 - Added new documentation chapters on [how dependency resolution
834 works](https://doc.rust-lang.org/nightly/cargo/reference/resolver.html) and
836 compatibility](https://doc.rust-lang.org/nightly/cargo/reference/semver.html),
837 along with suggestions on how to version your project and work with
839 [#8609](https://github.com/rust-lang/cargo/pull/8609)
842 - The comments added to `.gitignore` when it is modified have been tweaked to
844 [#8476](https://github.com/rust-lang/cargo/pull/8476)
845 - `cargo metadata` output should now be sorted to be deterministic.
846 [#8489](https://github.com/rust-lang/cargo/pull/8489)
847 - By default, build scripts and proc-macros are now built with `opt-level=0`
848 and the default codegen units, even in release mode.
849 [#8500](https://github.com/rust-lang/cargo/pull/8500)
850 - `workspace.default-members` is now filtered by `workspace.exclude`.
851 [#8485](https://github.com/rust-lang/cargo/pull/8485)
852 - `workspace.members` globs now ignore non-directory paths.
853 [#8511](https://github.com/rust-lang/cargo/pull/8511)
854 - git zlib errors now trigger a retry.
855 [#8520](https://github.com/rust-lang/cargo/pull/8520)
856 - "http" class git errors now trigger a retry.
857 [#8553](https://github.com/rust-lang/cargo/pull/8553)
858 - git dependencies now override the `core.autocrlf` git configuration value to
859 ensure they behave consistently across platforms, particularly when
860 vendoring git dependencies on Windows.
861 [#8523](https://github.com/rust-lang/cargo/pull/8523)
862 - If `Cargo.lock` needs to be updated, then it will be automatically
863 transitioned to the new V2 format. This format removes the `[metadata]`
864 table, and should be easier to merge changes in source control systems. This
865 format was introduced in 1.38, and made the default for new projects in
867 [#8554](https://github.com/rust-lang/cargo/pull/8554)
868 - Added preparation for support of git repositories with a non-"master"
869 default branch. Actual support will arrive in a future version. This
870 introduces some warnings:
871 - Warn if a git dependency does not specify a branch, and the default branch
872 on the repository is not "master". In the future, Cargo will fetch the
873 default branch. In this scenario, the branch should be explicitly
875 - Warn if a workspace has multiple dependencies to the same git repository,
876 one without a `branch` and one with `branch="master"`. Dependencies should
877 all use one form or the other.
878 [#8522](https://github.com/rust-lang/cargo/pull/8522)
879 - Warnings are now issued if a `required-features` entry lists a feature that
881 [#7950](https://github.com/rust-lang/cargo/pull/7950)
882 - Built-in aliases are now included in `cargo --list`.
883 [#8542](https://github.com/rust-lang/cargo/pull/8542)
884 - `cargo install` with a specific version that has been yanked will now
885 display an error message that it has been yanked, instead of "could not
887 [#8565](https://github.com/rust-lang/cargo/pull/8565)
888 - `cargo publish` with a package that has the `publish` field set to a single
889 registry, and no `--registry` flag has been given, will now publish to that
890 registry instead of generating an error.
891 [#8571](https://github.com/rust-lang/cargo/pull/8571)
894 - Fixed issue where if a project directory was moved, and one of the
895 build scripts did not use the `rerun-if-changed` directive, then that
896 build script was being rebuilt when it shouldn't.
897 [#8497](https://github.com/rust-lang/cargo/pull/8497)
898 - Console colors should now work on Windows 7 and 8.
899 [#8540](https://github.com/rust-lang/cargo/pull/8540)
900 - The `CARGO_TARGET_{triplet}_RUNNER` environment variable will now correctly
901 override the config file instead of trying to merge the commands.
902 [#8629](https://github.com/rust-lang/cargo/pull/8629)
903 - Fixed LTO with doctests.
904 [#8657](https://github.com/rust-lang/cargo/pull/8657)
905 [#8658](https://github.com/rust-lang/cargo/pull/8658)
908 - Added support for `-Z terminal-width` which tells `rustc` the width of the
909 terminal so that it can format diagnostics better.
910 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#terminal-width)
911 [#8427](https://github.com/rust-lang/cargo/pull/8427)
912 - Added ability to configure `-Z` unstable flags in config files via the
914 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html)
915 [#8393](https://github.com/rust-lang/cargo/pull/8393)
916 - Added `-Z build-std-features` flag to set features for the standard library.
917 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#build-std-features)
918 [#8490](https://github.com/rust-lang/cargo/pull/8490)
920 ## Cargo 1.46 (2020-08-27)
921 [9fcb8c1d...rust-1.46.0](https://github.com/rust-lang/cargo/compare/9fcb8c1d...rust-1.46.0)
924 - The `dl` key in `config.json` of a registry index now supports the
925 replacement markers `{prefix}` and `{lowerprefix}` to allow spreading crates
926 across directories similar to how the index itself is structured.
927 [docs](https://doc.rust-lang.org/nightly/cargo/reference/registries.html#index-format)
928 [#8267](https://github.com/rust-lang/cargo/pull/8267)
929 - Added new environment variables that are set during compilation:
930 - `CARGO_CRATE_NAME`: The name of the crate being built.
931 - `CARGO_BIN_NAME`: The name of the executable binary (if this is a binary crate).
932 - `CARGO_PKG_LICENSE`: The `license` field from the manifest.
933 - `CARGO_PKG_LICENSE_FILE`: The `license-file` field from the manifest.
934 [#8270](https://github.com/rust-lang/cargo/pull/8270)
935 [#8325](https://github.com/rust-lang/cargo/pull/8325)
936 [#8387](https://github.com/rust-lang/cargo/pull/8387)
937 - If the value for `readme` is not specified in `Cargo.toml`, it is now
938 automatically inferred from the existence of a file named `README`,
939 `README.md`, or `README.txt`. This can be suppressed by setting
941 [#8277](https://github.com/rust-lang/cargo/pull/8277)
942 - `cargo install` now supports the `--index` flag to install directly from an index.
943 [#8344](https://github.com/rust-lang/cargo/pull/8344)
944 - Added the `metadata` table to the `workspace` definition in `Cargo.toml`.
945 This can be used for arbitrary data similar to the `package.metadata` table.
946 [#8323](https://github.com/rust-lang/cargo/pull/8323)
947 - Added the `--target-dir` flag to `cargo install` to set the target directory.
948 [#8391](https://github.com/rust-lang/cargo/pull/8391)
949 - Changes to environment variables used by the
950 [`env!`](https://doc.rust-lang.org/std/macro.env.html) or
951 [`option_env!`](https://doc.rust-lang.org/std/macro.option_env.html) macros
952 are now automatically detected to trigger a rebuild.
953 [#8421](https://github.com/rust-lang/cargo/pull/8421)
954 - The `target` directory now includes the `CACHEDIR.TAG` file which is used by
955 some tools to exclude the directory from backups.
956 [#8378](https://github.com/rust-lang/cargo/pull/8378)
957 - Added docs about rustup's `+toolchain` syntax.
958 [#8455](https://github.com/rust-lang/cargo/pull/8455)
961 - A warning is now displayed if a git dependency includes a `#` fragment in
962 the URL. This was potentially confusing because Cargo itself displays git
963 URLs with this syntax, but it does not have any meaning outside of the
964 `Cargo.lock` file, and would not work properly.
965 [#8297](https://github.com/rust-lang/cargo/pull/8297)
966 - Various optimizations and fixes for bitcode embedding and LTO.
967 [#8349](https://github.com/rust-lang/cargo/pull/8349)
968 - Reduced the amount of data fetched for git dependencies. If Cargo knows the
969 branch or tag to fetch, it will now only fetch that branch or tag instead of
970 all branches and tags.
971 [#8363](https://github.com/rust-lang/cargo/pull/8363)
972 - Enhanced git fetch error messages.
973 [#8409](https://github.com/rust-lang/cargo/pull/8409)
974 - `.crate` files are now generated with GNU tar format instead of UStar, which
975 supports longer file names.
976 [#8453](https://github.com/rust-lang/cargo/pull/8453)
979 - Fixed a rare situation where an update to `Cargo.lock` failed once, but then
980 subsequent runs allowed it proceed.
981 [#8274](https://github.com/rust-lang/cargo/pull/8274)
982 - Removed assertion that Windows dylibs must have a `.dll` extension. Some
983 custom JSON spec targets may change the extension.
984 [#8310](https://github.com/rust-lang/cargo/pull/8310)
985 - Updated libgit2, which brings in a fix for zlib errors for some remote
986 git servers like googlesource.com.
987 [#8320](https://github.com/rust-lang/cargo/pull/8320)
988 - Fixed the GitHub fast-path check for up-to-date git dependencies on
990 [#8363](https://github.com/rust-lang/cargo/pull/8363)
991 - Fixed issue when enabling a feature with `pkg/feature` syntax, and `pkg` is
992 an optional dependency, but also a dev-dependency, and the dev-dependency
993 appears before the optional normal dependency in the registry summary, then
994 the optional dependency would not get activated.
995 [#8395](https://github.com/rust-lang/cargo/pull/8395)
996 - Fixed `clean -p` deleting the build directory if there is a test named
998 [#8398](https://github.com/rust-lang/cargo/pull/8398)
999 - Fixed indentation of multi-line Cargo error messages.
1000 [#8409](https://github.com/rust-lang/cargo/pull/8409)
1001 - Fixed issue where the automatic inclusion of the `--document-private-items`
1002 flag for rustdoc would override any flags passed to the `cargo rustdoc`
1004 [#8449](https://github.com/rust-lang/cargo/pull/8449)
1005 - Cargo will now include a version in the hash of the fingerprint directories
1006 to support backwards-incompatible changes to the fingerprint structure.
1007 [#8473](https://github.com/rust-lang/cargo/pull/8473)
1008 [#8488](https://github.com/rust-lang/cargo/pull/8488)
1011 - Added `-Zrustdoc-map` feature which provides external mappings for rustdoc
1012 (such as https://docs.rs/ links).
1013 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#rustdoc-map)
1014 [#8287](https://github.com/rust-lang/cargo/pull/8287)
1015 - Fixed feature calculation when a proc-macro is declared in `Cargo.toml` with
1016 an underscore (like `proc_macro = true`).
1017 [#8319](https://github.com/rust-lang/cargo/pull/8319)
1018 - Added support for setting `-Clinker` with `-Zdoctest-xcompile`.
1019 [#8359](https://github.com/rust-lang/cargo/pull/8359)
1020 - Fixed setting the `strip` profile field in config files.
1021 [#8454](https://github.com/rust-lang/cargo/pull/8454)
1023 ## Cargo 1.45 (2020-07-16)
1024 [ebda5065e...rust-1.45.0](https://github.com/rust-lang/cargo/compare/ebda5065...rust-1.45.0)
1029 - Changed official documentation to recommend `.cargo/config.toml` filenames
1030 (with the `.toml` extension). `.toml` extension support was added in 1.39.
1031 [#8121](https://github.com/rust-lang/cargo/pull/8121)
1032 - The `registry.index` config value is no longer allowed (it has been
1033 deprecated for 4 years).
1034 [#7973](https://github.com/rust-lang/cargo/pull/7973)
1035 - An error is generated if both `--index` and `--registry` are passed
1036 (previously `--index` was silently ignored).
1037 [#7973](https://github.com/rust-lang/cargo/pull/7973)
1038 - The `registry.token` config value is no longer used with the `--index` flag.
1039 This is intended to avoid potentially leaking the crates.io token to another
1041 [#7973](https://github.com/rust-lang/cargo/pull/7973)
1042 - Added a warning if `registry.token` is used with source replacement. It is
1043 intended this will be an error in future versions.
1044 [#7973](https://github.com/rust-lang/cargo/pull/7973)
1045 - Windows GNU targets now copy `.dll.a` import library files for DLL crate
1046 types to the output directory.
1047 [#8141](https://github.com/rust-lang/cargo/pull/8141)
1048 - Dylibs for all dependencies are now unconditionally copied to the output
1049 directory. Some obscure scenarios can cause an old dylib to be referenced
1050 between builds, and this ensures that all the latest copies are used.
1051 [#8139](https://github.com/rust-lang/cargo/pull/8139)
1052 - `package.exclude` can now match directory names. If a directory is
1053 specified, the entire directory will be excluded, and Cargo will not attempt
1054 to inspect it further. Previously Cargo would try to check every file in the
1055 directory which could cause problems if the directory contained unreadable
1057 [#8095](https://github.com/rust-lang/cargo/pull/8095)
1058 - When packaging with `cargo publish` or `cargo package`, Cargo can use git to
1059 guide its decision on which files to include. Previously this git-based
1060 logic required a `Cargo.toml` file to exist at the root of the repository.
1061 This is no longer required, so Cargo will now use git-based guidance even if
1062 there is not a `Cargo.toml` in the root of the repository.
1063 [#8095](https://github.com/rust-lang/cargo/pull/8095)
1064 - While unpacking a crate on Windows, if it fails to write a file because the
1065 file is a reserved Windows filename (like "aux.rs"), Cargo will display an
1066 extra message to explain why it failed.
1067 [#8136](https://github.com/rust-lang/cargo/pull/8136)
1068 - Failures to set mtime on files are now ignored. Some filesystems did not
1070 [#8185](https://github.com/rust-lang/cargo/pull/8185)
1071 - Certain classes of git errors will now recommend enabling
1072 `net.git-fetch-with-cli`.
1073 [#8166](https://github.com/rust-lang/cargo/pull/8166)
1074 - When doing an LTO build, Cargo will now instruct rustc not to perform
1075 codegen when possible. This may result in a faster build and use less disk
1076 space. Additionally, for non-LTO builds, Cargo will instruct rustc to not
1077 embed LLVM bitcode in libraries, which should decrease their size.
1078 [#8192](https://github.com/rust-lang/cargo/pull/8192)
1079 [#8226](https://github.com/rust-lang/cargo/pull/8226)
1080 [#8254](https://github.com/rust-lang/cargo/pull/8254)
1081 - The implementation for `cargo clean -p` has been rewritten so that it can
1082 more accurately remove the files for a specific package.
1083 [#8210](https://github.com/rust-lang/cargo/pull/8210)
1084 - The way Cargo computes the outputs from a build has been rewritten to be
1085 more complete and accurate. Newly tracked files will be displayed in JSON
1086 messages, and may be uplifted to the output directory in some cases. Some of
1087 the changes from this are:
1089 - `.exp` export files on Windows MSVC dynamic libraries are now tracked.
1090 - Proc-macros on Windows track import/export files.
1091 - All targets (like tests, etc.) that generate separate debug files
1092 (pdb/dSYM) are tracked.
1093 - Added .map files for wasm32-unknown-emscripten.
1094 - macOS dSYM directories are tracked for all dynamic libraries
1095 (dylib/cdylib/proc-macro) and for build scripts.
1097 There are a variety of other changes as a consequence of this:
1099 - Binary examples on Windows MSVC with a hyphen will now show up twice in
1100 the examples directory (`foo_bar.exe` and `foo-bar.exe`). Previously Cargo
1101 just renamed the file instead of hard-linking it.
1102 - Example libraries now follow the same rules for hyphen/underscore
1103 translation as normal libs (they will now use underscores).
1105 [#8210](https://github.com/rust-lang/cargo/pull/8210)
1106 - Cargo attempts to scrub any secrets from the debug log for HTTP debugging.
1107 [#8222](https://github.com/rust-lang/cargo/pull/8222)
1108 - Context has been added to many of Cargo's filesystem operations, so that
1109 error messages now provide more information, such as the path that caused
1111 [#8232](https://github.com/rust-lang/cargo/pull/8232)
1112 - Several commands now ignore the error if stdout or stderr is closed while it
1113 is running. For example `cargo install --list | grep -q cargo-fuzz` would
1114 previously sometimes panic because `grep -q` may close stdout before the
1115 command finishes. Regular builds continue to fail if stdout or stderr is
1116 closed, matching the behavior of many other build systems.
1117 [#8236](https://github.com/rust-lang/cargo/pull/8236)
1118 - If `cargo install` is given an exact version, like `--version=1.2.3`, it
1119 will now avoid updating the index if that version is already installed, and
1120 exit quickly indicating it is already installed.
1121 [#8022](https://github.com/rust-lang/cargo/pull/8022)
1122 - Changes to the `[patch]` section will now attempt to automatically update
1123 `Cargo.lock` to the new version. It should now also provide better error
1124 messages for the rare cases where it is unable to automatically update.
1125 [#8248](https://github.com/rust-lang/cargo/pull/8248)
1128 - Fixed copying Windows `.pdb` files to the output directory when the filename
1130 [#8123](https://github.com/rust-lang/cargo/pull/8123)
1131 - Fixed error where Cargo would fail when scanning if a package is inside a
1132 git repository when any of its ancestor paths is a symlink.
1133 [#8186](https://github.com/rust-lang/cargo/pull/8186)
1134 - Fixed `cargo update` with an unused `[patch]` so that it does not get
1135 stuck and refuse to update.
1136 [#8243](https://github.com/rust-lang/cargo/pull/8243)
1137 - Fixed a situation where Cargo would hang if stderr is closed, and the
1138 compiler generated a large number of messages.
1139 [#8247](https://github.com/rust-lang/cargo/pull/8247)
1140 - Fixed backtraces on macOS not showing filenames or line numbers. As a
1141 consequence of this, binary executables on apple targets do not include a
1142 hash in the filename in Cargo's cache. This means Cargo can only track one
1143 copy, so if you switch features or rustc versions, Cargo will need to
1144 rebuild the executable.
1145 [#8329](https://github.com/rust-lang/cargo/pull/8329)
1146 [#8335](https://github.com/rust-lang/cargo/pull/8335)
1147 - Fixed fingerprinting when using lld on Windows with a dylib. Cargo was
1148 erroneously thinking the dylib was never fresh.
1149 [#8290](https://github.com/rust-lang/cargo/pull/8290)
1150 [#8335](https://github.com/rust-lang/cargo/pull/8335)
1153 - Fixed passing the full path for `--target` to `rustdoc` when using JSON spec
1155 [#8094](https://github.com/rust-lang/cargo/pull/8094)
1156 - `-Cembed-bitcode=no` renamed to `-Cbitcode-in-rlib=no`
1157 [#8134](https://github.com/rust-lang/cargo/pull/8134)
1158 - Added new `resolver` field to `Cargo.toml` to opt-in to the new feature
1160 [#8129](https://github.com/rust-lang/cargo/pull/8129)
1161 - `-Zbuild-std` no longer treats std dependencies as "local". This means that
1162 it won't use incremental compilation for those dependencies, removes them
1163 from dep-info files, and caps lints at "allow".
1164 [#8177](https://github.com/rust-lang/cargo/pull/8177)
1165 - Added `-Zmultitarget` which allows multiple `--target` flags to build the
1166 same thing for multiple targets at once.
1167 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#multitarget)
1168 [#8167](https://github.com/rust-lang/cargo/pull/8167)
1169 - Added `strip` option to the profile to remove symbols and debug information.
1170 [docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#profile-strip-option)
1171 [#8246](https://github.com/rust-lang/cargo/pull/8246)
1172 - Fixed panic with `cargo tree --target=all -Zfeatures=all`.
1173 [#8269](https://github.com/rust-lang/cargo/pull/8269)
1175 ## Cargo 1.44 (2020-06-04)
1176 [bda50510...rust-1.44.0](https://github.com/rust-lang/cargo/compare/bda50510...rust-1.44.0)
1179 - 🔥 Added the `cargo tree` command.
1180 [docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-tree.html)
1181 [#8062](https://github.com/rust-lang/cargo/pull/8062)
1182 - Added warnings if a package has Windows-restricted filenames (like `nul`,
1183 `con`, `aux`, `prn`, etc.).
1184 [#7959](https://github.com/rust-lang/cargo/pull/7959)
1185 - Added a `"build-finished"` JSON message when compilation is complete so that
1186 tools can detect when they can stop listening for JSON messages with
1187 commands like `cargo run` or `cargo test`.
1188 [#8069](https://github.com/rust-lang/cargo/pull/8069)
1191 - Valid package names are now restricted to Unicode XID identifiers. This is
1192 mostly the same as before, except package names cannot start with a number
1194 [#7959](https://github.com/rust-lang/cargo/pull/7959)
1195 - `cargo new` and `init` will warn or reject additional package names
1196 (reserved Windows names, reserved Cargo directories, non-ASCII names,
1197 conflicting std names like `core`, etc.).
1198 [#7959](https://github.com/rust-lang/cargo/pull/7959)
1199 - Tests are no longer hard-linked into the output directory (`target/debug/`).
1200 This ensures tools will have access to debug symbols and execute tests in
1201 the same way as Cargo. Tools should use JSON messages to discover the path
1203 [#7965](https://github.com/rust-lang/cargo/pull/7965)
1204 - Updating git submodules now displays an "Updating" message for each
1206 [#7989](https://github.com/rust-lang/cargo/pull/7989)
1207 - File modification times are now preserved when extracting a `.crate` file.
1208 This reverses the change made in 1.40 where the mtime was not preserved.
1209 [#7935](https://github.com/rust-lang/cargo/pull/7935)
1210 - Build script warnings are now displayed separately when the build script
1212 [#8017](https://github.com/rust-lang/cargo/pull/8017)
1213 - Removed the `git-checkout` subcommand.
1214 [#8040](https://github.com/rust-lang/cargo/pull/8040)
1215 - The progress bar is now enabled for all unix platforms. Previously it was
1216 only Linux, macOS, and FreeBSD.
1217 [#8054](https://github.com/rust-lang/cargo/pull/8054)
1218 - Artifacts generated by pre-release versions of `rustc` now share the same
1219 filenames. This means that changing nightly versions will not leave stale
1220 files in the build directory.
1221 [#8073](https://github.com/rust-lang/cargo/pull/8073)
1222 - Invalid package names are rejected when using renamed dependencies.
1223 [#8090](https://github.com/rust-lang/cargo/pull/8090)
1224 - Added a certain class of HTTP2 errors as "spurious" that will get retried.
1225 [#8102](https://github.com/rust-lang/cargo/pull/8102)
1226 - Allow `cargo package --list` to succeed, even if there are other validation
1227 errors (such as `Cargo.lock` generation problem, or missing dependencies).
1228 [#8175](https://github.com/rust-lang/cargo/pull/8175)
1229 [#8215](https://github.com/rust-lang/cargo/pull/8215)
1232 - Cargo no longer buffers excessive amounts of compiler output in memory.
1233 [#7838](https://github.com/rust-lang/cargo/pull/7838)
1234 - Symbolic links in git repositories now work on Windows.
1235 [#7996](https://github.com/rust-lang/cargo/pull/7996)
1236 - Fixed an issue where `profile.dev` was not loaded from a config file with
1237 `cargo test` when the `dev` profile was not defined in `Cargo.toml`.
1238 [#8012](https://github.com/rust-lang/cargo/pull/8012)
1239 - When a binary is built as an implicit dependency of an integration test,
1240 it now checks `dep_name/feature_name` syntax in `required-features` correctly.
1241 [#8020](https://github.com/rust-lang/cargo/pull/8020)
1242 - Fixed an issue where Cargo would not detect that an executable (such as an
1243 integration test) needs to be rebuilt when the previous build was
1244 interrupted with Ctrl-C.
1245 [#8087](https://github.com/rust-lang/cargo/pull/8087)
1246 - Protect against some (unknown) situations where Cargo could panic when the
1247 system monotonic clock doesn't appear to be monotonic.
1248 [#8114](https://github.com/rust-lang/cargo/pull/8114)
1249 - Fixed panic with `cargo clean -p` if the package has a build script.
1250 [#8216](https://github.com/rust-lang/cargo/pull/8216)
1253 - Fixed panic with new feature resolver and required-features.
1254 [#7962](https://github.com/rust-lang/cargo/pull/7962)
1255 - Added `RUSTC_WORKSPACE_WRAPPER` environment variable, which provides a way
1256 to wrap `rustc` for workspace members only, and affects the filename hash so
1257 that artifacts produced by the wrapper are cached separately. This usage can
1258 be seen on nightly clippy with `cargo clippy -Zunstable-options`.
1259 [#7533](https://github.com/rust-lang/cargo/pull/7533)
1260 - Added `--unit-graph` CLI option to display Cargo's internal dependency graph
1262 [#7977](https://github.com/rust-lang/cargo/pull/7977)
1263 - Changed `-Zbuild_dep` to `-Zhost_dep`, and added proc-macros to the feature
1265 [#8003](https://github.com/rust-lang/cargo/pull/8003)
1266 [#8028](https://github.com/rust-lang/cargo/pull/8028)
1267 - Fixed so that `--crate-version` is not automatically passed when the flag
1268 is found in `RUSTDOCFLAGS`.
1269 [#8014](https://github.com/rust-lang/cargo/pull/8014)
1270 - Fixed panic with `-Zfeatures=dev_dep` and `check --profile=test`.
1271 [#8027](https://github.com/rust-lang/cargo/pull/8027)
1272 - Fixed panic with `-Zfeatures=itarget` with certain host dependencies.
1273 [#8048](https://github.com/rust-lang/cargo/pull/8048)
1274 - Added support for `-Cembed-bitcode=no`, which provides a performance boost
1275 and disk-space usage reduction for non-LTO builds.
1276 [#8066](https://github.com/rust-lang/cargo/pull/8066)
1277 - `-Zpackage-features` has been extended with several changes intended to make
1278 it easier to select features on the command-line in a workspace.
1279 [#8074](https://github.com/rust-lang/cargo/pull/8074)
1281 ## Cargo 1.43 (2020-04-23)
1282 [9d32b7b0...rust-1.43.0](https://github.com/rust-lang/cargo/compare/9d32b7b0...rust-1.43.0)
1285 - 🔥 Profiles may now be specified in config files (and environment variables).
1286 [docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#profile)
1287 [#7823](https://github.com/rust-lang/cargo/pull/7823)
1288 - ❗ Added `CARGO_BIN_EXE_<name>` environment variable when building
1289 integration tests. This variable contains the path to any `[[bin]]` targets
1290 in the package. Integration tests should use the `env!` macro to determine
1291 the path to a binary to execute.
1292 [docs](https://doc.rust-lang.org/nightly/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-crates)
1293 [#7697](https://github.com/rust-lang/cargo/pull/7697)
1296 - `cargo install --git` now honors workspaces in a git repository. This allows
1297 workspace settings, like `[patch]`, `[replace]`, or `[profile]` to be used.
1298 [#7768](https://github.com/rust-lang/cargo/pull/7768)
1299 - `cargo new` will now run `rustfmt` on the new files to pick up rustfmt
1300 settings like `tab_spaces` so that the new file matches the user's preferred
1301 indentation settings.
1302 [#7827](https://github.com/rust-lang/cargo/pull/7827)
1303 - Environment variables printed with "very verbose" output (`-vv`) are now
1304 consistently sorted.
1305 [#7877](https://github.com/rust-lang/cargo/pull/7877)
1306 - Debug logging for fingerprint rebuild-detection now includes more information.
1307 [#7888](https://github.com/rust-lang/cargo/pull/7888)
1308 [#7890](https://github.com/rust-lang/cargo/pull/7890)
1309 [#7952](https://github.com/rust-lang/cargo/pull/7952)
1310 - Added warning during publish if the license-file doesn't exist.
1311 [#7905](https://github.com/rust-lang/cargo/pull/7905)
1312 - The `license-file` file is automatically included during publish, even if it
1313 is not explicitly listed in the `include` list or is in a location outside
1314 of the root of the package.
1315 [#7905](https://github.com/rust-lang/cargo/pull/7905)
1316 - `CARGO_CFG_DEBUG_ASSERTIONS` and `CARGO_CFG_PROC_MACRO` are no longer set
1317 when running a build script. These were inadvertently set in the past, but
1318 had no meaning as they were always true. Additionally, `cfg(proc-macro)`
1319 is no longer supported in a `target` expression.
1320 [#7943](https://github.com/rust-lang/cargo/pull/7943)
1321 [#7970](https://github.com/rust-lang/cargo/pull/7970)
1324 - Global command-line flags now work with aliases (like `cargo -v b`).
1325 [#7837](https://github.com/rust-lang/cargo/pull/7837)
1326 - Required-features using dependency syntax (like `renamed_dep/feat_name`) now
1327 handle renamed dependencies correctly.
1328 [#7855](https://github.com/rust-lang/cargo/pull/7855)
1329 - Fixed a rare situation where if a build script is run multiple times during
1330 the same build, Cargo will now keep the results separate instead of losing
1331 the output of the first execution.
1332 [#7857](https://github.com/rust-lang/cargo/pull/7857)
1333 - Fixed incorrect interpretation of environment variable
1334 `CARGO_TARGET_*_RUNNER=true` as a boolean. Also improved related env var
1336 [#7891](https://github.com/rust-lang/cargo/pull/7891)
1337 - Updated internal libgit2 library, bringing various fixes to git support.
1338 [#7939](https://github.com/rust-lang/cargo/pull/7939)
1339 - `cargo package` / `cargo publish` should no longer buffer the entire
1340 contents of each file in memory.
1341 [#7946](https://github.com/rust-lang/cargo/pull/7946)
1342 - Ignore more invalid `Cargo.toml` files in a git dependency. Cargo currently
1343 walks the entire repo to find the requested package. Certain invalid
1344 manifests were already skipped, and now it should skip all of them.
1345 [#7947](https://github.com/rust-lang/cargo/pull/7947)
1348 - Added `build.out-dir` config variable to set the output directory.
1349 [#7810](https://github.com/rust-lang/cargo/pull/7810)
1350 - Added `-Zjobserver-per-rustc` feature to support improved performance for
1352 [#7731](https://github.com/rust-lang/cargo/pull/7731)
1353 - Fixed filename collision with `build-std` and crates like `cc`.
1354 [#7860](https://github.com/rust-lang/cargo/pull/7860)
1355 - `-Ztimings` will now save its report even if there is an error.
1356 [#7872](https://github.com/rust-lang/cargo/pull/7872)
1357 - Updated `--config` command-line flag to support taking a path to a config
1359 [#7901](https://github.com/rust-lang/cargo/pull/7901)
1360 - Added new feature resolver.
1361 [#7820](https://github.com/rust-lang/cargo/pull/7820)
1362 - Rustdoc docs now automatically include the version of the package in the
1363 side bar (requires `-Z crate-versions` flag).
1364 [#7903](https://github.com/rust-lang/cargo/pull/7903)
1366 ## Cargo 1.42 (2020-03-12)
1367 [0bf7aafe...rust-1.42.0](https://github.com/rust-lang/cargo/compare/0bf7aafe...rust-1.42.0)
1370 - Added documentation on git authentication.
1371 [#7658](https://github.com/rust-lang/cargo/pull/7658)
1372 - Bitbucket Pipeline badges are now supported on crates.io.
1373 [#7663](https://github.com/rust-lang/cargo/pull/7663)
1374 - `cargo vendor` now accepts the `--versioned-dirs` option to force it to
1375 always include the version number in each package's directory name.
1376 [#7631](https://github.com/rust-lang/cargo/pull/7631)
1377 - The `proc_macro` crate is now automatically added to the extern prelude for
1378 proc-macro packages. This means that `extern crate proc_macro;` is no longer
1379 necessary for proc-macros.
1380 [#7700](https://github.com/rust-lang/cargo/pull/7700)
1383 - Emit a warning if `debug_assertions`, `test`, `proc_macro`, or `feature=` is
1384 used in a `cfg()` expression.
1385 [#7660](https://github.com/rust-lang/cargo/pull/7660)
1386 - Large update to the Cargo documentation, adding new chapters on Cargo
1387 targets, workspaces, and features.
1388 [#7733](https://github.com/rust-lang/cargo/pull/7733)
1389 - Windows: `.lib` DLL import libraries are now copied next to the dll for all
1390 Windows MSVC targets. Previously it was only supported for
1391 `pc-windows-msvc`. This adds DLL support for `uwp-windows-msvc` targets.
1392 [#7758](https://github.com/rust-lang/cargo/pull/7758)
1393 - The `ar` field in the `[target]` configuration is no longer read. It has
1394 been ignored for over 4 years.
1395 [#7763](https://github.com/rust-lang/cargo/pull/7763)
1396 - Bash completion file simplified and updated for latest changes.
1397 [#7789](https://github.com/rust-lang/cargo/pull/7789)
1398 - Credentials are only loaded when needed, instead of every Cargo command.
1399 [#7774](https://github.com/rust-lang/cargo/pull/7774)
1402 - Removed `--offline` empty index check, which was a false positive in some
1404 [#7655](https://github.com/rust-lang/cargo/pull/7655)
1405 - Files and directories starting with a `.` can now be included in a package
1406 by adding it to the `include` list.
1407 [#7680](https://github.com/rust-lang/cargo/pull/7680)
1408 - Fixed `cargo login` removing alternative registry tokens when previous
1409 entries existed in the credentials file.
1410 [#7708](https://github.com/rust-lang/cargo/pull/7708)
1411 - Fixed `cargo vendor` from panicking when used with alternative registries.
1412 [#7718](https://github.com/rust-lang/cargo/pull/7718)
1413 - Fixed incorrect explanation in the fingerprint debug log message.
1414 [#7749](https://github.com/rust-lang/cargo/pull/7749)
1415 - A `[source]` that is defined multiple times will now result in an error.
1416 Previously it was randomly picking a source, which could cause
1417 non-deterministic behavior.
1418 [#7751](https://github.com/rust-lang/cargo/pull/7751)
1419 - `dep_kinds` in `cargo metadata` are now de-duplicated.
1420 [#7756](https://github.com/rust-lang/cargo/pull/7756)
1421 - Fixed packaging where `Cargo.lock` was listed in `.gitignore` in a
1422 subdirectory inside a git repository. Previously it was assuming
1423 `Cargo.lock` was at the root of the repo.
1424 [#7779](https://github.com/rust-lang/cargo/pull/7779)
1425 - Partial file transfer errors will now cause an automatic retry.
1426 [#7788](https://github.com/rust-lang/cargo/pull/7788)
1427 - Linux: Fixed panic if CPU iowait stat decreases.
1428 [#7803](https://github.com/rust-lang/cargo/pull/7803)
1429 - Fixed using the wrong sysroot for detecting host compiler settings when
1430 `--sysroot` is passed in via `RUSTFLAGS`.
1431 [#7798](https://github.com/rust-lang/cargo/pull/7798)
1434 - `build-std` now uses `--extern` instead of `--sysroot` to find sysroot
1436 [#7699](https://github.com/rust-lang/cargo/pull/7699)
1437 - Added `--config` command-line option to set config settings.
1438 [#7649](https://github.com/rust-lang/cargo/pull/7649)
1439 - Added `include` config setting which allows including another config file.
1440 [#7649](https://github.com/rust-lang/cargo/pull/7649)
1441 - Profiles in config files now support any named profile. Previously it was
1442 limited to dev/release.
1443 [#7750](https://github.com/rust-lang/cargo/pull/7750)
1445 ## Cargo 1.41 (2020-01-30)
1446 [5da4b4d4...rust-1.41.0](https://github.com/rust-lang/cargo/compare/5da4b4d4...rust-1.41.0)
1449 - 🔥 Cargo now uses a new `Cargo.lock` file format. This new format should
1450 support easier merges in source control systems. Projects using the old
1451 format will continue to use the old format, only new `Cargo.lock` files will
1453 [#7579](https://github.com/rust-lang/cargo/pull/7579)
1454 - 🔥 `cargo install` will now upgrade already installed packages instead of
1456 [#7560](https://github.com/rust-lang/cargo/pull/7560)
1457 - 🔥 Profile overrides have been added. This allows overriding profiles for
1458 individual dependencies or build scripts. See [the
1459 documentation](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#overrides)
1461 [#7591](https://github.com/rust-lang/cargo/pull/7591)

1464 - Added documentation for Cargo's JSON output.
1465 [#7595](https://github.com/rust-lang/cargo/pull/7595)
1466 - Significant expansion of config and environment variable documentation.
1467 [#7650](https://github.com/rust-lang/cargo/pull/7650)
1468 - Add back support for `BROWSER` environment variable for `cargo doc --open`.
1469 [#7576](https://github.com/rust-lang/cargo/pull/7576)

1481 [#7570](https://github.com/rust-lang/cargo/pull/7570)
1482 - Ignore `cargo login` text from copy/paste in token.
1483 [#7588](https://github.com/rust-lang/cargo/pull/7588)

1485 [#7602](https://github.com/rust-lang/cargo/pull/7602)
1486 - Remove `**/*.rs.bk` from `.gitignore`.
1487 [#7647](https://github.com/rust-lang/cargo/pull/7647)
1490 - Fix unused warnings for some keys in the `build` config section.
1491 [#7575](https://github.com/rust-lang/cargo/pull/7575)
1492 - Linux: Don't panic when parsing `/proc/stat`.
1493 [#7580](https://github.com/rust-lang/cargo/pull/7580)
1494 - Don't show canonical path in `cargo vendor`.
1495 [#7629](https://github.com/rust-lang/cargo/pull/7629)
1500 ## Cargo 1.40 (2019-12-19)
1501 [1c6ec66d...5da4b4d4](https://github.com/rust-lang/cargo/compare/1c6ec66d...5da4b4d4)
1504 - Added `http.ssl-version` config option to control the version of TLS,
1505 along with min/max versions.
1506 [#7308](https://github.com/rust-lang/cargo/pull/7308)
1507 - 🔥 Compiler warnings are now cached on disk. If a build generates warnings,
1508 re-running the build will now re-display the warnings.
1509 [#7450](https://github.com/rust-lang/cargo/pull/7450)
1510 - Added `--filter-platform` option to `cargo metadata` to narrow the nodes
1511 shown in the resolver graph to only packages included for the given target
1513 [#7376](https://github.com/rust-lang/cargo/pull/7376)
1516 - Cargo's "platform" `cfg` parsing has been extracted into a separate crate
1517 named `cargo-platform`.
1518 [#7375](https://github.com/rust-lang/cargo/pull/7375)
1519 - Dependencies extracted into Cargo's cache no longer preserve mtimes to
1520 reduce syscall overhead.
1521 [#7465](https://github.com/rust-lang/cargo/pull/7465)
1522 - Windows: EXE files no longer include a metadata hash in the filename.
1523 This helps with debuggers correlating the filename with the PDB file.
1524 [#7400](https://github.com/rust-lang/cargo/pull/7400)
1525 - Wasm32: `.wasm` files are no longer treated as an "executable", allowing
1526 `cargo test` and `cargo run` to work properly with the generated `.js` file.
1527 [#7476](https://github.com/rust-lang/cargo/pull/7476)
1528 - crates.io now supports SPDX 3.6 licenses.
1529 [#7481](https://github.com/rust-lang/cargo/pull/7481)

1534 - `cargo publish` now allows dev-dependencies without a version key to be
1535 published. A git or path-only dev-dependency will be removed from the
1536 package manifest before uploading.
1537 [#7333](https://github.com/rust-lang/cargo/pull/7333)
1538 - `--features` and `--no-default-features` in the root of a virtual workspace
1539 will now generate an error instead of being ignored.
1540 [#7507](https://github.com/rust-lang/cargo/pull/7507)
1541 - Generated files (like `Cargo.toml` and `Cargo.lock`) in a package archive
1542 now have their timestamp set to the current time instead of the epoch.
1543 [#7523](https://github.com/rust-lang/cargo/pull/7523)
1544 - The `-Z` flag parser is now more strict, rejecting more invalid syntax.
1545 [#7531](https://github.com/rust-lang/cargo/pull/7531)
1548 - Fixed an issue where if a package had an `include` field, and `Cargo.lock`
1549 in `.gitignore`, and a binary or example target, and the `Cargo.lock` exists
1550 in the current project, it would fail to publish complaining the
1551 `Cargo.lock` was dirty.
1552 [#7448](https://github.com/rust-lang/cargo/pull/7448)
1553 - Fixed a panic in a particular combination of `[patch]` entries.
1554 [#7452](https://github.com/rust-lang/cargo/pull/7452)
1555 - Windows: Better error message when `cargo test` or `rustc` crashes in an
1556 abnormal way, such as a signal or seg fault.
1557 [#7535](https://github.com/rust-lang/cargo/pull/7535)
1560 - The `mtime-on-use` feature may now be enabled via the
1561 `unstable.mtime_on_use` config option.
1562 [#7411](https://github.com/rust-lang/cargo/pull/7411)
1563 - Added support for named profiles.
1564 [#6989](https://github.com/rust-lang/cargo/pull/6989)
1565 - Added `-Zpanic-abort-tests` to allow building and running tests with the
1566 "abort" panic strategy.
1567 [#7460](https://github.com/rust-lang/cargo/pull/7460)
1568 - Changed `build-std` to use `--sysroot`.
1569 [#7421](https://github.com/rust-lang/cargo/pull/7421)
1570 - Various fixes and enhancements to `-Ztimings`.

1576 [#7429](https://github.com/rust-lang/cargo/pull/7429)
1577 - Profile overrides have renamed the syntax to be
1578 `[profile.dev.package.NAME]`.
1579 [#7504](https://github.com/rust-lang/cargo/pull/7504)
1580 - Fixed warnings for unused profile overrides in a workspace.
1581 [#7536](https://github.com/rust-lang/cargo/pull/7536)
1583 ## Cargo 1.39 (2019-11-07)
1584 [e853aa97...1c6ec66d](https://github.com/rust-lang/cargo/compare/e853aa97...1c6ec66d)
1587 - Config files may now use the `.toml` filename extension.
1588 [#7295](https://github.com/rust-lang/cargo/pull/7295)
1589 - The `--workspace` flag has been added as an alias for `--all` to help avoid
1590 confusion about the meaning of "all".
1591 [#7241](https://github.com/rust-lang/cargo/pull/7241)
1592 - The `publish` field has been added to `cargo metadata`.
1593 [#7354](https://github.com/rust-lang/cargo/pull/7354)
1596 - Display more information if parsing the output from `rustc` fails.
1597 [#7236](https://github.com/rust-lang/cargo/pull/7236)
1598 - TOML errors now show the column number.
1599 [#7248](https://github.com/rust-lang/cargo/pull/7248)
1600 - `cargo vendor` no longer deletes files in the `vendor` directory that starts
1602 [#7242](https://github.com/rust-lang/cargo/pull/7242)
1603 - `cargo fetch` will now show manifest warnings.
1604 [#7243](https://github.com/rust-lang/cargo/pull/7243)
1605 - `cargo publish` will now check git submodules if they contain any
1606 uncommitted changes.
1607 [#7245](https://github.com/rust-lang/cargo/pull/7245)
1608 - In a build script, `cargo:rustc-flags` now allows `-l` and `-L` flags
1610 [#7257](https://github.com/rust-lang/cargo/pull/7257)
1611 - When `cargo install` replaces an older version of a package it will now
1612 delete any installed binaries that are no longer present in the newly
1614 [#7246](https://github.com/rust-lang/cargo/pull/7246)
1615 - A git dependency may now also specify a `version` key when published. The
1616 `git` value will be stripped from the uploaded crate, matching the behavior
1617 of `path` dependencies.
1618 [#7237](https://github.com/rust-lang/cargo/pull/7237)
1619 - The behavior of workspace default-members has changed. The default-members
1620 now only applies when running Cargo in the root of the workspace. Previously
1621 it would always apply regardless of which directory Cargo is running in.
1622 [#7270](https://github.com/rust-lang/cargo/pull/7270)
1623 - libgit2 updated pulling in all upstream changes.
1624 [#7275](https://github.com/rust-lang/cargo/pull/7275)
1625 - Bump `home` dependency for locating home directories.
1626 [#7277](https://github.com/rust-lang/cargo/pull/7277)
1627 - zsh completions have been updated.
1628 [#7296](https://github.com/rust-lang/cargo/pull/7296)
1629 - SSL connect errors are now retried.
1630 [#7318](https://github.com/rust-lang/cargo/pull/7318)
1631 - The jobserver has been changed to acquire N tokens (instead of N-1), and
1632 then immediately acquires the extra token. This was changed to accommodate
1633 the `cc` crate on Windows to allow it to release its implicit token.
1634 [#7344](https://github.com/rust-lang/cargo/pull/7344)
1635 - The scheduling algorithm for choosing which crate to build next has been
1636 changed. It now chooses the crate with the greatest number of transitive
1637 crates waiting on it. Previously it used a maximum topological depth.
1638 [#7390](https://github.com/rust-lang/cargo/pull/7390)
1639 - RUSTFLAGS are no longer incorporated in the metadata and filename hash,
1640 reversing the change from 1.33 that added it. This means that any change to
1641 RUSTFLAGS will cause a recompile, and will not affect symbol munging.
1642 [#7459](https://github.com/rust-lang/cargo/pull/7459)
1645 - Git dependencies with submodules with shorthand SSH URLs (like
1646 `git@github.com/user/repo.git`) should now work.
1647 [#7238](https://github.com/rust-lang/cargo/pull/7238)
1648 - Handle broken symlinks when creating `.dSYM` symlinks on macOS.
1649 [#7268](https://github.com/rust-lang/cargo/pull/7268)
1650 - Fixed issues with multiple versions of the same crate in a `[patch]` table.
1651 [#7303](https://github.com/rust-lang/cargo/pull/7303)
1652 - Fixed issue with custom target `.json` files where a substring of the name
1653 matches an unsupported crate type (like "bin").
1654 [#7363](https://github.com/rust-lang/cargo/issues/7363)
1655 - Fixed issues with generating documentation for proc-macro crate types.
1656 [#7159](https://github.com/rust-lang/cargo/pull/7159)
1657 - Fixed hang if Cargo panics within a build thread.
1658 [#7366](https://github.com/rust-lang/cargo/pull/7366)
1659 - Fixed rebuild detection if a `build.rs` script issues different `rerun-if`
1660 directives between builds. Cargo was erroneously causing a rebuild after the
1662 [#7373](https://github.com/rust-lang/cargo/pull/7373)
1663 - Properly handle canonical URLs for `[patch]` table entries, preventing
1664 the patch from working after the first time it is used.
1665 [#7368](https://github.com/rust-lang/cargo/pull/7368)
1666 - Fixed an issue where integration tests were waiting for the package binary
1667 to finish building before starting their own build. They now may build
1669 [#7394](https://github.com/rust-lang/cargo/pull/7394)
1670 - Fixed accidental change in the previous release on how `--features a b` flag
1671 is interpreted, restoring the original behavior where this is interpreted as
1672 `--features a` along with the argument `b` passed to the command. To pass
1673 multiple features, use quotes around the features to pass multiple features
1674 like `--features "a b"`, or use commas, or use multiple `--features` flags.
1675 [#7419](https://github.com/rust-lang/cargo/pull/7419)
1678 - Basic support for building the standard library directly from Cargo has been
1680 ([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#build-std))
1681 [#7216](https://github.com/rust-lang/cargo/pull/7216)
1682 - Added `-Ztimings` feature to generate an HTML report on the time spent on
1683 individual compilation steps. This also may output completion steps on the
1684 console and JSON data.
1685 ([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#timings))
1686 [#7311](https://github.com/rust-lang/cargo/pull/7311)
1687 - Added ability to cross-compile doctests.
1688 ([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#doctest-xcompile))
1689 [#6892](https://github.com/rust-lang/cargo/pull/6892)
1691 ## Cargo 1.38 (2019-09-26)
1692 [4c1fa54d...23ef9a4e](https://github.com/rust-lang/cargo/compare/4c1fa54d...23ef9a4e)
1695 - 🔥 Cargo build pipelining has been enabled by default to leverage more idle CPU
1696 parallelism during builds.
1697 [#7143](https://github.com/rust-lang/cargo/pull/7143)
1698 - The `--message-format` option to Cargo can now be specified multiple times and
1699 accepts a comma-separated list of values. In addition to the previous values
1700 it also now accepts `json-diagnostic-short` and
1701 `json-diagnostic-rendered-ansi` which configures the output coming from rustc
1702 in `json` message mode.
1703 [#7214](https://github.com/rust-lang/cargo/pull/7214)
1704 - Cirrus CI badges are now supported on crates.io.
1705 [#7119](https://github.com/rust-lang/cargo/pull/7119)
1706 - A new format for `Cargo.lock` has been introduced. This new format is
1707 intended to avoid source-control merge conflicts more often, and to
1708 generally make it safer to merge changes. This new format is *not* enabled
1709 at this time, though Cargo will use it if it sees it. At some point in the
1710 future, it is intended that this will become the default.
1711 [#7070](https://github.com/rust-lang/cargo/pull/7070)
1712 - Progress bar support added for FreeBSD.
1713 [#7222](https://github.com/rust-lang/cargo/pull/7222)
1716 - The `-q` flag will no longer suppress the root error message for an error
1718 [#7116](https://github.com/rust-lang/cargo/pull/7116)
1719 - The Cargo Book is now published with mdbook 0.3 providing a number of
1720 formatting fixes and improvements.
1721 [#7140](https://github.com/rust-lang/cargo/pull/7140)
1722 - The `--features` command-line flag can now be specified multiple times.
1723 The list of features from all the flags are joined together.
1724 [#7084](https://github.com/rust-lang/cargo/pull/7084)
1725 - Package include/exclude glob-vs-gitignore warnings have been removed.
1726 Packages may now use gitignore-style matching without producing any
1728 [#7170](https://github.com/rust-lang/cargo/pull/7170)
1729 - Cargo now shows the command and output when parsing `rustc` output fails
1730 when querying `rustc` for information like `cfg` values.
1731 [#7185](https://github.com/rust-lang/cargo/pull/7185)
1732 - `cargo package`/`cargo publish` now allows a symbolic link to a git
1733 submodule to include that submodule.
1734 [#6817](https://github.com/rust-lang/cargo/pull/6817)
1735 - Improved the error message when a version requirement does not
1736 match any versions, but there are pre-release versions available.
1737 [#7191](https://github.com/rust-lang/cargo/pull/7191)
1740 - Fixed using the wrong directory when updating git repositories when using
1741 the `git-fetch-with-cli` config option, and the `GIT_DIR` environment
1742 variable is set. This may happen when running cargo from git callbacks.
1743 [#7082](https://github.com/rust-lang/cargo/pull/7082)
1744 - Fixed dep-info files being overwritten for targets that have separate debug
1745 outputs. For example, binaries on `-apple-` targets with `.dSYM` directories
1746 would overwrite the `.d` file.
1747 [#7057](https://github.com/rust-lang/cargo/pull/7057)
1748 - Fix `[patch]` table not preserving "one major version per source" rule.
1749 [#7118](https://github.com/rust-lang/cargo/pull/7118)
1750 - Ignore `--remap-path-prefix` flags for the metadata hash in the `cargo
1751 rustc` command. This was causing the remap settings to inadvertently affect
1753 [#7134](https://github.com/rust-lang/cargo/pull/7134)
1754 - Fixed cycle detection in `[patch]` dependencies.
1755 [#7174](https://github.com/rust-lang/cargo/pull/7174)
1756 - Fixed `cargo new` leaving behind a symlink on Windows when `core.symlinks`
1757 git config is true. Also adds a number of fixes and updates from upstream
1759 [#7176](https://github.com/rust-lang/cargo/pull/7176)
1760 - macOS: Fixed setting the flag to mark the `target` directory to be excluded
1762 [#7192](https://github.com/rust-lang/cargo/pull/7192)
1763 - Fixed `cargo fix` panicking under some situations involving multi-byte
1765 [#7221](https://github.com/rust-lang/cargo/pull/7221)
1768 - Added `cargo fix --clippy` which will apply machine-applicable fixes from
1770 [#7069](https://github.com/rust-lang/cargo/pull/7069)
1771 - Added `-Z binary-dep-depinfo` flag to add change tracking for binary
1772 dependencies like the standard library.
1773 [#7137](https://github.com/rust-lang/cargo/pull/7137)
1774 [#7219](https://github.com/rust-lang/cargo/pull/7219)
1775 - `cargo clippy-preview` will always run, even if no changes have been made.
1776 [#7157](https://github.com/rust-lang/cargo/pull/7157)
1777 - Fixed exponential blowup when using `CARGO_BUILD_PIPELINING`.
1778 [#7062](https://github.com/rust-lang/cargo/pull/7062)
1779 - Fixed passing args to clippy in `cargo clippy-preview`.
1780 [#7162](https://github.com/rust-lang/cargo/pull/7162)
1782 ## Cargo 1.37 (2019-08-15)
1783 [c4fcfb72...9edd0891](https://github.com/rust-lang/cargo/compare/c4fcfb72...9edd0891)
1786 - Added `doctest` field to `cargo metadata` to determine if a target's
1787 documentation is tested.
1788 [#6953](https://github.com/rust-lang/cargo/pull/6953)
1789 [#6965](https://github.com/rust-lang/cargo/pull/6965)
1791 vendor`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-vendor.html)
1792 command is now built-in to Cargo. This command may be used to create a local
1793 copy of the sources of all dependencies.
1794 [#6869](https://github.com/rust-lang/cargo/pull/6869)
1795 - 🔥 The "publish lockfile" feature is now stable. This feature will
1796 automatically include the `Cargo.lock` file when a package is published if
1797 it contains a binary executable target. By default, Cargo will ignore
1798 `Cargo.lock` when installing a package. To force Cargo to use the
1799 `Cargo.lock` file included in the published package, use `cargo install
1800 --locked`. This may be useful to ensure that `cargo install` consistently
1801 reproduces the same result. It may also be useful when a semver-incompatible
1802 change is accidentally published to a dependency, providing a way to fall
1803 back to a version that is known to work.
1804 [#7026](https://github.com/rust-lang/cargo/pull/7026)
1805 - 🔥 The `default-run` feature has been stabilized. This feature allows you to
1806 specify which binary executable to run by default with `cargo run` when a
1807 package includes multiple binaries. Set the `default-run` key in the
1808 `[package]` table in `Cargo.toml` to the name of the binary to use by
1810 [#7056](https://github.com/rust-lang/cargo/pull/7056)
1813 - `cargo package` now verifies that build scripts do not create empty
1815 [#6973](https://github.com/rust-lang/cargo/pull/6973)
1816 - A warning is now issued if `cargo doc` generates duplicate outputs, which
1817 causes files to be randomly stomped on. This may happen for a variety of
1818 reasons (renamed dependencies, multiple versions of the same package,
1819 packages with renamed libraries, etc.). This is a known bug, which needs
1820 more work to handle correctly.
1821 [#6998](https://github.com/rust-lang/cargo/pull/6998)
1822 - Enabling a dependency's feature with `--features foo/bar` will no longer
1823 compile the current crate with the `foo` feature if `foo` is not an optional
1825 [#7010](https://github.com/rust-lang/cargo/pull/7010)
1826 - If `--remap-path-prefix` is passed via RUSTFLAGS, it will no longer affect
1827 the filename metadata hash.
1828 [#6966](https://github.com/rust-lang/cargo/pull/6966)
1829 - libgit2 has been updated to 0.28.2, which Cargo uses to access git
1830 repositories. This brings in hundreds of changes and fixes since it was last
1831 updated in November.
1832 [#7018](https://github.com/rust-lang/cargo/pull/7018)
1833 - Cargo now supports absolute paths in the dep-info files generated by rustc.
1834 This is laying the groundwork for [tracking
1835 binaries](https://github.com/rust-lang/rust/pull/61727), such as libstd, for
1836 rebuild detection. (Note: this contains a known bug.)
1837 [#7030](https://github.com/rust-lang/cargo/pull/7030)
1840 - Fixed how zsh completions fetch the list of commands.
1841 [#6956](https://github.com/rust-lang/cargo/pull/6956)
1842 - "+ debuginfo" is no longer printed in the build summary when `debug` is set
1844 [#6971](https://github.com/rust-lang/cargo/pull/6971)
1845 - Fixed `cargo doc` with an example configured with `doc = true` to document
1847 [#7023](https://github.com/rust-lang/cargo/pull/7023)
1848 - Don't fail if a read-only lock cannot be acquired in CARGO_HOME. This helps
1849 when CARGO_HOME doesn't exist, but `--locked` is used which means CARGO_HOME
1851 [#7149](https://github.com/rust-lang/cargo/pull/7149)
1852 - Reverted a change in 1.35 which released jobserver tokens when Cargo blocked
1853 on a lock file. It caused a deadlock in some situations.
1854 [#7204](https://github.com/rust-lang/cargo/pull/7204)
1857 - Added [compiler message
1858 caching](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#cache-messages).
1859 The `-Z cache-messages` flag makes cargo cache the compiler output so that
1860 future runs can redisplay previous warnings.
1861 [#6933](https://github.com/rust-lang/cargo/pull/6933)
1862 - `-Z mtime-on-use` no longer touches intermediate artifacts.
1863 [#7050](https://github.com/rust-lang/cargo/pull/7050)
1865 ## Cargo 1.36 (2019-07-04)
1866 [6f3e9c36...c4fcfb72](https://github.com/rust-lang/cargo/compare/6f3e9c36...c4fcfb72)
1869 - Added more detailed documentation on target auto-discovery.
1870 [#6898](https://github.com/rust-lang/cargo/pull/6898)
1871 - 🔥 Stabilize the `--offline` flag which allows using cargo without a network
1873 [#6934](https://github.com/rust-lang/cargo/pull/6934)
1874 [#6871](https://github.com/rust-lang/cargo/pull/6871)
1877 - `publish = ["crates-io"]` may be added to the manifest to restrict
1878 publishing to crates.io only.
1879 [#6838](https://github.com/rust-lang/cargo/pull/6838)
1880 - macOS: Only include the default paths if `DYLD_FALLBACK_LIBRARY_PATH` is not
1881 set. Also, remove `/lib` from the default set.
1882 [#6856](https://github.com/rust-lang/cargo/pull/6856)
1883 - `cargo publish` will now exit early if the login token is not available.
1884 [#6854](https://github.com/rust-lang/cargo/pull/6854)
1885 - HTTP/2 stream errors are now considered "spurious" and will cause a retry.
1886 [#6861](https://github.com/rust-lang/cargo/pull/6861)
1887 - Setting a feature on a dependency where that feature points to a *required*
1888 dependency is now an error. Previously it was a warning.
1889 [#6860](https://github.com/rust-lang/cargo/pull/6860)
1890 - The `registry.index` config value now supports relative `file:` URLs.
1891 [#6873](https://github.com/rust-lang/cargo/pull/6873)
1892 - macOS: The `.dSYM` directory is now symbolically linked next to example
1893 binaries without the metadata hash so that debuggers can find it.
1894 [#6891](https://github.com/rust-lang/cargo/pull/6891)
1895 - The default `Cargo.toml` template for now projects now includes a comment
1896 providing a link to the documentation.
1897 [#6881](https://github.com/rust-lang/cargo/pull/6881)
1898 - Some improvements to the wording of the crate download summary.
1899 [#6916](https://github.com/rust-lang/cargo/pull/6916)
1900 [#6920](https://github.com/rust-lang/cargo/pull/6920)
1901 - ✨ Changed `RUST_LOG` environment variable to `CARGO_LOG` so that user code
1902 that uses the `log` crate will not display cargo's debug output.
1903 [#6918](https://github.com/rust-lang/cargo/pull/6918)
1904 - `Cargo.toml` is now always included when packaging, even if it is not listed
1905 in `package.include`.
1906 [#6925](https://github.com/rust-lang/cargo/pull/6925)
1907 - Package include/exclude values now use gitignore patterns instead of glob
1908 patterns. [#6924](https://github.com/rust-lang/cargo/pull/6924)
1909 - Provide a better error message when crates.io times out. Also improve error
1910 messages with other HTTP response codes.
1911 [#6936](https://github.com/rust-lang/cargo/pull/6936)
1914 - Resolver performance improvements for some cases.
1915 [#6853](https://github.com/rust-lang/cargo/pull/6853)
1916 - Optimized how cargo reads the index JSON files by caching the results.
1917 [#6880](https://github.com/rust-lang/cargo/pull/6880)
1918 [#6912](https://github.com/rust-lang/cargo/pull/6912)
1919 [#6940](https://github.com/rust-lang/cargo/pull/6940)
1920 - Various performance improvements.
1921 [#6867](https://github.com/rust-lang/cargo/pull/6867)
1924 - More carefully track the on-disk fingerprint information for dependencies.
1925 This can help in some rare cases where the build is interrupted and
1926 restarted. [#6832](https://github.com/rust-lang/cargo/pull/6832)
1927 - `cargo run` now correctly passes non-UTF8 arguments to the child process.
1928 [#6849](https://github.com/rust-lang/cargo/pull/6849)
1929 - Fixed bash completion to run on bash 3.2, the stock version in macOS.
1930 [#6905](https://github.com/rust-lang/cargo/pull/6905)
1931 - Various fixes and improvements to zsh completion.
1932 [#6926](https://github.com/rust-lang/cargo/pull/6926)
1933 [#6929](https://github.com/rust-lang/cargo/pull/6929)
1934 - Fix `cargo update` ignoring `-p` arguments if the `Cargo.lock` file was
1936 [#6904](https://github.com/rust-lang/cargo/pull/6904)
1939 - Added [`-Z install-upgrade`
1940 feature](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#install-upgrade)
1941 to track details about installed crates and to update them if they are
1942 out-of-date. [#6798](https://github.com/rust-lang/cargo/pull/6798)
1943 - Added the [`public-dependency`
1944 feature](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#public-dependency)
1945 which allows tracking public versus private dependencies.
1946 [#6772](https://github.com/rust-lang/cargo/pull/6772)
1947 - Added build pipelining via the `build.pipelining` config
1948 option (`CARGO_BUILD_PIPELINING` env var).
1949 [#6883](https://github.com/rust-lang/cargo/pull/6883)
1950 - The `publish-lockfile` feature has had some significant changes. The default
1951 is now `true`, the `Cargo.lock` will always be published for binary crates.
1952 The `Cargo.lock` is now regenerated during publishing. `cargo install` now
1953 ignores the `Cargo.lock` file by default, and requires `--locked` to use the
1954 lock file. Warnings have been added if yanked dependencies are detected.
1955 [#6840](https://github.com/rust-lang/cargo/pull/6840)
1957 ## Cargo 1.35 (2019-05-23)
1958 [6789d8a0...6f3e9c36](https://github.com/rust-lang/cargo/compare/6789d8a0...6f3e9c36)
1961 - Added the `rustc-cdylib-link-arg` key for build scripts to specify linker
1962 arguments for cdylib crates.
1963 [#6298](https://github.com/rust-lang/cargo/pull/6298)
1966 - When passing a test filter, such as `cargo test foo`, don't build examples
1967 (unless they set `test = true`).
1968 [#6683](https://github.com/rust-lang/cargo/pull/6683)
1969 - Forward the `--quiet` flag from `cargo test` to the libtest harness so that
1970 tests are actually quiet.
1971 [#6358](https://github.com/rust-lang/cargo/pull/6358)
1972 - The verification step in `cargo package` that checks if any files are
1973 modified is now stricter. It uses a hash of the contents instead of checking
1974 filesystem mtimes. It also checks *all* files in the package.
1975 [#6740](https://github.com/rust-lang/cargo/pull/6740)
1976 - Jobserver tokens are now released whenever Cargo blocks on a file lock.
1977 [#6748](https://github.com/rust-lang/cargo/pull/6748)

1979 table headers with the same name.
1980 [#6761](https://github.com/rust-lang/cargo/pull/6761)
1981 - Removed the `CARGO_PKG_*` environment variables from the metadata hash and
1982 added them to the fingerprint instead. This means that when these values
1983 change, stale artifacts are not left behind. Also added the "repository"
1984 value to the fingerprint.
1985 [#6785](https://github.com/rust-lang/cargo/pull/6785)
1986 - `cargo metadata` no longer shows a `null` field for a dependency without a
1987 library in `resolve.nodes.deps`. The dependency is no longer shown.
1988 [#6534](https://github.com/rust-lang/cargo/pull/6534)
1989 - `cargo new` will no longer include an email address in the `authors` field
1990 if it is set to the empty string.
1991 [#6802](https://github.com/rust-lang/cargo/pull/6802)
1992 - `cargo doc --open` now works when documenting multiple packages.
1993 [#6803](https://github.com/rust-lang/cargo/pull/6803)
1994 - `cargo install --path P` now loads the `.cargo/config` file from the
1995 directory P. [#6805](https://github.com/rust-lang/cargo/pull/6805)
1996 - Using semver metadata in a version requirement (such as `1.0.0+1234`) now
1997 issues a warning that it is ignored.
1998 [#6806](https://github.com/rust-lang/cargo/pull/6806)
1999 - `cargo install` now rejects certain combinations of flags where some flags
2000 would have been ignored.
2001 [#6801](https://github.com/rust-lang/cargo/pull/6801)
2002 - Resolver performance improvements for some cases.
2003 [#6776](https://github.com/rust-lang/cargo/pull/6776)
2006 - Fixed running separate commands (such as `cargo build` then `cargo test`)
2007 where the second command could use stale results from a build script.
2008 [#6720](https://github.com/rust-lang/cargo/pull/6720)
2009 - Fixed `cargo fix` not working properly if a `.gitignore` file that matched
2010 the root package directory.
2011 [#6767](https://github.com/rust-lang/cargo/pull/6767)
2012 - Fixed accidentally compiling a lib multiple times if `panic=unwind` was set
2013 in a profile. [#6781](https://github.com/rust-lang/cargo/pull/6781)
2014 - Paths to JSON files in `build.target` config value are now canonicalized to
2015 fix building dependencies.
2016 [#6778](https://github.com/rust-lang/cargo/pull/6778)
2017 - Fixed re-running a build script if its compilation was interrupted (such as
2018 if it is killed). [#6782](https://github.com/rust-lang/cargo/pull/6782)
2019 - Fixed `cargo new` initializing a fossil repo.
2020 [#6792](https://github.com/rust-lang/cargo/pull/6792)
2021 - Fixed supporting updating a git repo that has a force push when using the
2022 `git-fetch-with-cli` feature. `git-fetch-with-cli` also shows more error
2023 information now when it fails.
2024 [#6800](https://github.com/rust-lang/cargo/pull/6800)
2025 - `--example` binaries built for the WASM target are fixed to no longer
2026 include a metadata hash in the filename, and are correctly emitted in the
2027 `compiler-artifact` JSON message.
2028 [#6812](https://github.com/rust-lang/cargo/pull/6812)
2031 - `cargo clippy-preview` is now a built-in cargo command.
2032 [#6759](https://github.com/rust-lang/cargo/pull/6759)
2033 - The `build-override` profile setting now includes proc-macros and their
2035 [#6811](https://github.com/rust-lang/cargo/pull/6811)
2036 - Optional and target dependencies now work better with `-Z offline`.
2037 [#6814](https://github.com/rust-lang/cargo/pull/6814)
2039 ## Cargo 1.34 (2019-04-11)
2040 [f099fe94...6789d8a0](https://github.com/rust-lang/cargo/compare/f099fe94...6789d8a0)
2043 - 🔥 Stabilized support for [alternate
2044 registries](https://doc.rust-lang.org/1.34.0/cargo/reference/registries.html).
2045 [#6654](https://github.com/rust-lang/cargo/pull/6654)
2046 - Added documentation on using builds.sr.ht Continuous Integration with Cargo.
2047 [#6565](https://github.com/rust-lang/cargo/pull/6565)
2048 - `Cargo.lock` now includes a comment at the top that it is `@generated`.
2049 [#6548](https://github.com/rust-lang/cargo/pull/6548)
2050 - Azure DevOps badges are now supported.
2051 [#6264](https://github.com/rust-lang/cargo/pull/6264)
2052 - Added a warning if `--exclude` flag specifies an unknown package.
2053 [#6679](https://github.com/rust-lang/cargo/pull/6679)
2056 - `cargo test --doc --no-run` doesn't do anything, so it now displays an error
2057 to that effect. [#6628](https://github.com/rust-lang/cargo/pull/6628)
2058 - Various updates to bash completion: add missing options and commands,
2059 support libtest completions, use rustup for `--target` completion, fallback
2060 to filename completion, fix editing the command line.
2061 [#6644](https://github.com/rust-lang/cargo/pull/6644)
2062 - Publishing a crate with a `[patch]` section no longer generates an error.
2063 The `[patch]` section is removed from the manifest before publishing.
2064 [#6535](https://github.com/rust-lang/cargo/pull/6535)
2065 - `build.incremental = true` config value is now treated the same as
2066 `CARGO_INCREMENTAL=1`, previously it was ignored.
2067 [#6688](https://github.com/rust-lang/cargo/pull/6688)
2068 - Errors from a registry are now always displayed regardless of the HTTP
2069 response code. [#6771](https://github.com/rust-lang/cargo/pull/6771)
2072 - Fixed bash completion for `cargo run --example`.
2073 [#6578](https://github.com/rust-lang/cargo/pull/6578)
2074 - Fixed a race condition when using a *local* registry and running multiple
2075 cargo commands at the same time that build the same crate.
2076 [#6591](https://github.com/rust-lang/cargo/pull/6591)
2077 - Fixed some flickering and excessive updates of the progress bar.
2078 [#6615](https://github.com/rust-lang/cargo/pull/6615)
2079 - Fixed a hang when using a git credential helper that returns incorrect
2080 credentials. [#6681](https://github.com/rust-lang/cargo/pull/6681)
2081 - Fixed resolving yanked crates with a local registry.
2082 [#6750](https://github.com/rust-lang/cargo/pull/6750)
2085 - Added `-Z mtime-on-use` flag to cause the mtime to be updated on the
2086 filesystem when a crate is used. This is intended to be able to track stale
2087 artifacts in the future for cleaning up unused files.
2088 [#6477](https://github.com/rust-lang/cargo/pull/6477)
2089 [#6573](https://github.com/rust-lang/cargo/pull/6573)
2090 - Added experimental `-Z dual-proc-macros` to build proc macros for both the
2091 host and the target.
2092 [#6547](https://github.com/rust-lang/cargo/pull/6547)
2094 ## Cargo 1.33 (2019-02-28)
2095 [8610973a...f099fe94](https://github.com/rust-lang/cargo/compare/8610973a...f099fe94)
2098 - `compiler-artifact` JSON messages now include an `"executable"` key which
2099 includes the path to the executable that was built.
2100 [#6363](https://github.com/rust-lang/cargo/pull/6363)
2101 - The man pages have been rewritten, and are now published with the web
2102 documentation. [#6405](https://github.com/rust-lang/cargo/pull/6405)
2103 - `cargo login` now displays a confirmation after saving the token.
2104 [#6466](https://github.com/rust-lang/cargo/pull/6466)
2105 - A warning is now emitted if a `[patch]` entry does not match any package.
2106 [#6470](https://github.com/rust-lang/cargo/pull/6470)
2107 - `cargo metadata` now includes the `links` key for a package.
2108 [#6480](https://github.com/rust-lang/cargo/pull/6480)
2109 - "Very verbose" output with `-vv` now displays the environment variables that
2110 cargo sets when it runs a process.
2111 [#6492](https://github.com/rust-lang/cargo/pull/6492)
2112 - `--example`, `--bin`, `--bench`, or `--test` without an argument now lists
2113 the available targets for those options.
2114 [#6505](https://github.com/rust-lang/cargo/pull/6505)
2115 - Windows: If a process fails with an extended status exit code, a
2116 human-readable name for the code is now displayed.
2117 [#6532](https://github.com/rust-lang/cargo/pull/6532)
2118 - Added `--features`, `--no-default-features`, and `--all-features` flags to
2119 the `cargo package` and `cargo publish` commands to use the given features
2120 when verifying the package.
2121 [#6453](https://github.com/rust-lang/cargo/pull/6453)
2124 - If `cargo fix` fails to compile the fixed code, the rustc errors are now
2125 displayed on the console.
2126 [#6419](https://github.com/rust-lang/cargo/pull/6419)
2127 - Hide the `--host` flag from `cargo login`, it is unused.
2128 [#6466](https://github.com/rust-lang/cargo/pull/6466)
2129 - Build script fingerprints now include the rustc version.
2130 [#6473](https://github.com/rust-lang/cargo/pull/6473)
2131 - macOS: Switched to setting `DYLD_FALLBACK_LIBRARY_PATH` instead of
2132 `DYLD_LIBRARY_PATH`. [#6355](https://github.com/rust-lang/cargo/pull/6355)
2133 - `RUSTFLAGS` is now included in the metadata hash, meaning that changing
2134 the flags will not overwrite previously built files.
2135 [#6503](https://github.com/rust-lang/cargo/pull/6503)
2136 - When updating the crate graph, unrelated yanked crates were erroneously
2137 removed. They are now kept at their original version if possible. This was
2138 causing unrelated packages to be downgraded during `cargo update -p
2139 somecrate`. [#5702](https://github.com/rust-lang/cargo/issues/5702)
2140 - TOML files now support the [0.5 TOML
2141 syntax](https://github.com/toml-lang/toml/blob/master/CHANGELOG.md#050--2018-07-11).
2144 - `cargo fix` will now ignore suggestions that modify multiple files.
2145 [#6402](https://github.com/rust-lang/cargo/pull/6402)
2146 - `cargo fix` will now only fix one target at a time, to deal with targets
2147 which share the same source files.
2148 [#6434](https://github.com/rust-lang/cargo/pull/6434)
2149 - Fixed bash completion showing the list of cargo commands.
2150 [#6461](https://github.com/rust-lang/cargo/issues/6461)
2151 - `cargo init` will now avoid creating duplicate entries in `.gitignore`
2152 files. [#6521](https://github.com/rust-lang/cargo/pull/6521)
2153 - Builds now attempt to detect if a file is modified in the middle of a
2154 compilation, allowing you to build again and pick up the new changes. This
2155 is done by keeping track of when the compilation *starts* not when it
2156 finishes. Also, [#5919](https://github.com/rust-lang/cargo/pull/5919) was
2157 reverted, meaning that cargo does *not* treat equal filesystem mtimes as
2158 requiring a rebuild. [#6484](https://github.com/rust-lang/cargo/pull/6484)
2161 - Allow using registry *names* in `[patch]` tables instead of just URLs.
2162 [#6456](https://github.com/rust-lang/cargo/pull/6456)
2163 - `cargo metadata` added the `registry` key for dependencies.
2164 [#6500](https://github.com/rust-lang/cargo/pull/6500)
2165 - Registry names are now restricted to the same style as
2166 package names (alphanumeric, `-` and `_` characters).
2167 [#6469](https://github.com/rust-lang/cargo/pull/6469)
2168 - `cargo login` now displays the `/me` URL from the registry config.
2169 [#6466](https://github.com/rust-lang/cargo/pull/6466)
2170 - `cargo login --registry=NAME` now supports interactive input for the token.
2171 [#6466](https://github.com/rust-lang/cargo/pull/6466)
2172 - Registries may now elide the `api` key from `config.json` to indicate they
2173 do not support API access.
2174 [#6466](https://github.com/rust-lang/cargo/pull/6466)
2175 - Fixed panic when using `--message-format=json` with metabuild.
2176 [#6432](https://github.com/rust-lang/cargo/pull/6432)
2177 - Fixed detection of publishing to crates.io when using alternate registries.
2178 [#6525](https://github.com/rust-lang/cargo/pull/6525)

2184 - Registries may now display warnings after a successful publish.
2185 [#6303](https://github.com/rust-lang/cargo/pull/6303)
2186 - Added a [glossary](https://doc.rust-lang.org/cargo/appendix/glossary.html)
2187 to the documentation. [#6321](https://github.com/rust-lang/cargo/pull/6321)
2188 - Added the alias `c` for `cargo check`.
2189 [#6218](https://github.com/rust-lang/cargo/pull/6218)
2192 - 🔥 HTTP/2 multiplexing is now enabled by default. The `http.multiplexing`
2193 config value may be used to disable it.
2194 [#6271](https://github.com/rust-lang/cargo/pull/6271)
2195 - Use ANSI escape sequences to clear lines instead of spaces.
2196 [#6233](https://github.com/rust-lang/cargo/pull/6233)
2197 - Disable git templates when checking out git dependencies, which can cause
2198 problems. [#6252](https://github.com/rust-lang/cargo/pull/6252)
2199 - Include the `--update-head-ok` git flag when using the
2200 `net.git-fetch-with-cli` option. This can help prevent failures when
2201 fetching some repositories.
2202 [#6250](https://github.com/rust-lang/cargo/pull/6250)
2203 - When extracting a crate during the verification step of `cargo package`, the
2204 filesystem mtimes are no longer set, which was failing on some rare
2205 filesystems. [#6257](https://github.com/rust-lang/cargo/pull/6257)
2206 - `crate-type = ["proc-macro"]` is now treated the same as `proc-macro = true`
2207 in `Cargo.toml`. [#6256](https://github.com/rust-lang/cargo/pull/6256)
2208 - An error is raised if `dependencies`, `features`, `target`, or `badges` is
2209 set in a virtual workspace. Warnings are displayed if `replace` or `patch`
2210 is used in a workspace member.
2211 [#6276](https://github.com/rust-lang/cargo/pull/6276)
2212 - Improved performance of the resolver in some cases.
2213 [#6283](https://github.com/rust-lang/cargo/pull/6283)
2214 [#6366](https://github.com/rust-lang/cargo/pull/6366)
2215 - `.rmeta` files are no longer hard-linked into the base target directory
2216 (`target/debug`). [#6292](https://github.com/rust-lang/cargo/pull/6292)
2217 - A warning is issued if multiple targets are built with the same output
2218 filenames. [#6308](https://github.com/rust-lang/cargo/pull/6308)
2219 - When using `cargo build` (without `--release`) benchmarks are now built
2220 using the "test" profile instead of "bench". This makes it easier to debug
2221 benchmarks, and avoids confusing behavior.
2222 [#6309](https://github.com/rust-lang/cargo/pull/6309)
2223 - User aliases may now override built-in aliases (`b`, `r`, `t`, and `c`).
2224 [#6259](https://github.com/rust-lang/cargo/pull/6259)
2225 - Setting `autobins=false` now disables auto-discovery of inferred targets.
2226 [#6329](https://github.com/rust-lang/cargo/pull/6329)
2227 - `cargo verify-project` will now fail on stable if the project uses unstable
2228 features. [#6326](https://github.com/rust-lang/cargo/pull/6326)
2229 - Platform targets with an internal `.` within the name are now allowed.
2230 [#6255](https://github.com/rust-lang/cargo/pull/6255)
2231 - `cargo clean --release` now only deletes the release directory.
2232 [#6349](https://github.com/rust-lang/cargo/pull/6349)
2235 - Avoid adding extra angle brackets in email address for `cargo new`.
2236 [#6243](https://github.com/rust-lang/cargo/pull/6243)
2237 - The progress bar is disabled if the CI environment variable is set.
2238 [#6281](https://github.com/rust-lang/cargo/pull/6281)
2239 - Avoid retaining all rustc output in memory.
2240 [#6289](https://github.com/rust-lang/cargo/pull/6289)
2241 - If JSON parsing fails, and rustc exits nonzero, don't lose the parse failure
2242 message. [#6290](https://github.com/rust-lang/cargo/pull/6290)
2243 - Fixed renaming a project directory with build scripts.
2244 [#6328](https://github.com/rust-lang/cargo/pull/6328)
2245 - Fixed `cargo run --example NAME` to work correctly if the example sets
2246 `crate_type = ["bin"]`.
2247 [#6330](https://github.com/rust-lang/cargo/pull/6330)
2248 - Fixed issue with `cargo package` git discovery being too aggressive. The
2249 `--allow-dirty` now completely disables the git repo checks.
2250 [#6280](https://github.com/rust-lang/cargo/pull/6280)
2251 - Fixed build change tracking for `[patch]` deps which resulted in `cargo
2252 build` rebuilding when it shouldn't.
2253 [#6493](https://github.com/rust-lang/cargo/pull/6493)
2256 - Allow usernames in registry URLs.
2257 [#6242](https://github.com/rust-lang/cargo/pull/6242)
