[b60a1555...HEAD](https://github.com/rust-lang/cargo/compare/b60a1555...HEAD)
### Added
### Changed
### Fixed
### Nightly only
- `-Zcargo-lints`: Don't always inherit workspace lints.
[#13812](https://github.com/rust-lang/cargo/pull/13812)
### Documentation
### Internal
## Cargo 1.79 (2024-06-13)
[2fe739fc...rust-1.79.0](https://github.com/rust-lang/cargo/compare/2fe739fc...rust-1.79.0)
### Added
- 🎉 `cargo add` respects `package.rust-version` a.k.a. MSRV when adding new
dependencies. The behavior can be overridden by specifying a version requirement,
or passing the `--ignore-rust-version` flag.
([RFC 3537](https://github.com/rust-lang/rfcs/blob/master/text/3537-msrv-resolver.md))
[#13608](https://github.com/rust-lang/cargo/pull/13608)
- A new `Locking` status message shows dependency changes on any command.
For `cargo update`, it also tells you if any dependency version is outdated.
[#13561](https://github.com/rust-lang/cargo/pull/13561)
[#13647](https://github.com/rust-lang/cargo/pull/13647)
[#13651](https://github.com/rust-lang/cargo/pull/13651)
[#13657](https://github.com/rust-lang/cargo/pull/13657)
[#13759](https://github.com/rust-lang/cargo/pull/13759)
[#13764](https://github.com/rust-lang/cargo/pull/13764)
### Changed
- ❗️ `RUSTC_WRAPPER`, `RUSTC_WORKSPACE_WRAPPER`, and variables from the `[env]`
table now also apply to the initial `rustc -vV` invocation Cargo uses for
probing rustc information.
[#13659](https://github.com/rust-lang/cargo/pull/13659)
- ❗️ Turns dependencies like `foo = { optional = true }` from `version="*"`
dependencies with a warning into errors.
This behavior has been considered a bug from the beginning.
[#13775](https://github.com/rust-lang/cargo/pull/13775)
- ❗️ Replace dashes with underscores also if `lib.name` is inferred from `package.name`.
This change aligns to the documented behavior. One caveat is that JSON messages
emitted by Cargo, like via `cargo metadata` or `--message-format=json`,
will start reporting underscore lib names.
[#12783](https://github.com/rust-lang/cargo/pull/12783)
- Switch to `gitoxide` for listing files. This improves the performance of
build script and `cargo doc` for computing cache freshness,
as well as fixes some subtle bugs for `cargo publish`.
[#13592](https://github.com/rust-lang/cargo/pull/13592)
[#13696](https://github.com/rust-lang/cargo/pull/13696)
[#13704](https://github.com/rust-lang/cargo/pull/13704)
[#13777](https://github.com/rust-lang/cargo/pull/13777)
- Warn on `-Zlints` being passed and no longer necessary.
[#13632](https://github.com/rust-lang/cargo/pull/13632)
- Warn on unused `workspace.dependencies` keys on virtual workspaces.
[#13664](https://github.com/rust-lang/cargo/pull/13664)
- Emit 1.77 build script syntax error only when msrv is incompatible.
[#13808](https://github.com/rust-lang/cargo/pull/13808)
- cargo-init: don't assign `target.name` in Cargo.toml if the value can be inferred.
[#13606](https://github.com/rust-lang/cargo/pull/13606)
- cargo-package: normalize paths in `Cargo.toml`, including replacing `\` with `/`.
[#13729](https://github.com/rust-lang/cargo/pull/13729)
- cargo-test: recategorize cargo test's `--doc` flag under “Target Selection”.
[#13756](https://github.com/rust-lang/cargo/pull/13756)
### Fixed
- Dont panic when resolving an empty alias.
[#13613](https://github.com/rust-lang/cargo/pull/13613)
- When using `--target`, the default debuginfo strip rule also applies.
Note that on Windows MSVC Cargo no longer strips by default.
[#13618](https://github.com/rust-lang/cargo/pull/13618)
- Don't crash on Cargo.toml parse errors that point to multi-byte character
[#13780](https://github.com/rust-lang/cargo/pull/13780)

[#13682](https://github.com/rust-lang/cargo/pull/13682)
- cargo-add: Preserve comments when updating simple deps
[#13655](https://github.com/rust-lang/cargo/pull/13655)
- cargo-fix: dont apply same suggestion twice.
[#13728](https://github.com/rust-lang/cargo/pull/13728)
- cargo-package: error when the package specified via `--package` cannot be found
[#13735](https://github.com/rust-lang/cargo/pull/13735)
- credential-provider: trim newlines in tokens from stdin.
[#13770](https://github.com/rust-lang/cargo/pull/13770)
### Nightly only
- 🔥 cargo-update: allows `--precise` to specify a pre-release version of a package
([RFC 3493](https://github.com/rust-lang/rfcs/blob/master/text/3493-precise-pre-release-cargo-update.md))
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#precise-pre-release))
[#13626](https://github.com/rust-lang/cargo/pull/13626)
- RFC 3491: Unused dependencies cleanup
[#13778](https://github.com/rust-lang/cargo/pull/13778)

and [`cargo-test-macro`](https://crates.io/crates/cargo-test-macro)!
They are designed for testing Cargo itself,
so no guarantee on any stability across versions.
The crates.io publish of this crate is the same as other members crates.
They follow Rust's [6-week release process](https://doc.crates.io/contrib/process/release.html#cratesio-publishing).
[#13418](https://github.com/rust-lang/cargo/pull/13418)

[7bb7b539...rust-1.78.0](https://github.com/rust-lang/cargo/compare/7bb7b539...rust-1.78.0)
### Added
- Stabilize global cache data tracking. The `-Zgc` flag is still unstable.

## Cargo 1.77.1 (2024-03-28)
### Fixed
- Debuginfo is no longer stripped by default for Windows MSVC targets. This caused an unexpected regression in 1.77.0 that broke backtraces.
[#13654](https://github.com/rust-lang/cargo/pull/13654)
## Cargo 1.77 (2024-03-21)
[1a2666dd...rust-1.77.0](https://github.com/rust-lang/cargo/compare/1a2666dd...rust-1.77.0)
### Added
- 🎉 Stabilize the package identifier format as [Package ID Spec](https://doc.rust-lang.org/nightly/cargo/reference/pkgid-spec.html).
This format can be used across most of the commands in Cargo, including the
`--package`/`-p` flag, `cargo pkgid`, `cargo metadata`, and JSON messages
from `--message-format=json`.

[#12201](https://github.com/rust-lang/cargo/pull/12201)
[#13212](https://github.com/rust-lang/cargo/pull/13212)
### Changed
- 🎉 Disabling debuginfo now implies `strip = "debuginfo"` (when `strip` is not set)
to strip pre-existing debuginfo coming from the standard library,
reducing the default size of release binaries considerably
(from ~4.5 MiB down to ~450 KiB for helloworld on Linux x64).

### Internal
- 🎉 New member crate [`cargo-util-schemas`](https://crates.io/crates/cargo-util-schemas)!
This contains low-level Cargo schema types, focusing on `serde` and `FromStr`
for use in reading files and parsing command-lines.
Any logic for getting final semantics from these will likely need other tools
to process, like `cargo metadata`.
The crates.io publish of this crate is the same as other members crates.
It follows Rust's [6-week release process](https://doc.crates.io/contrib/process/release.html#cratesio-publishing).

## Cargo 1.74 (2023-11-16)
[80eca0e5...rust-1.74.0](https://github.com/rust-lang/cargo/compare/80eca0e5...rust-1.74.0)
### Added
- 🎉 The `[lints]` table has been stabilized, allowing you to configure reporting levels for rustc and other tool lints in `Cargo.toml`.
([RFC 3389](https://github.com/rust-lang/rfcs/blob/master/text/3389-manifest-lint.md))
([docs](https://doc.rust-lang.org/nightly/cargo/reference/manifest.html#the-lints-section))
[#12584](https://github.com/rust-lang/cargo/pull/12584)
[#12648](https://github.com/rust-lang/cargo/pull/12648)
- 🎉 The unstable features `credential-process` and `registry-auth` have been stabilized.
These features consolidate the way to authenticate with private registries.
([RFC 2730](https://github.com/rust-lang/rfcs/blob/master/text/2730-cargo-token-from-process.md))
([RFC 3139](https://github.com/rust-lang/rfcs/blob/master/text/3139-cargo-alternative-registry-auth.md))

[#12671](https://github.com/rust-lang/cargo/pull/12671)
[#12709](https://github.com/rust-lang/cargo/pull/12709)
Notable changes:
- Introducing a new protocol for both external and built-in providers to store and retrieve credentials for registry authentication.
- Adding the `auth-required` field in the registry index's `config.json`, enabling authenticated sparse index, crate downloads, and search API.
- For using alternative registries with authentication, a credential provider must be configured to avoid unknowingly storing unencrypted credentials on disk.
- These settings can be configured in `[registry]` and `[registries]` tables.
- 🎉 `--keep-going` flag has been stabilized and is now available in each build command
(except `bench` and `test`, which have `--no-fail-fast` instead).
([docs](https://doc.rust-lang.org/cargo/commands/cargo-build.html#option-cargo-build---keep-going))
[#12568](https://github.com/rust-lang/cargo/pull/12568)

## Cargo 1.73 (2023-10-05)
[45782b6b...rust-1.73.0](https://github.com/rust-lang/cargo/compare/45782b6b...rust-1.73.0)
### Added
- Print environment variables for `cargo run/bench/test` in extra verbose mode `-vv`.
[#12498](https://github.com/rust-lang/cargo/pull/12498)
- Display package versions on Cargo timings graph.
[#12420](https://github.com/rust-lang/cargo/pull/12420)
### Changed
- ❗️ Cargo now bails out when using `cargo::` in custom build scripts. This is
a preparation for an upcoming change in build script invocations.
[#12332](https://github.com/rust-lang/cargo/pull/12332)
- ❗️ `cargo login` no longer accept any token after the `--` syntax.
Arguments after `--` are now reserved in the preparation of the new credential provider feature.
This introduces a regression that overlooks the `cargo login -- <token>` support in previous versions.
[#12499](https://github.com/rust-lang/cargo/pull/12499)
- Make Cargo `--help` easier to browse.
[#11905](https://github.com/rust-lang/cargo/pull/11905)
- Prompt the use of `--nocapture` flag if `cargo test` process is terminated via a signal.
[#12463](https://github.com/rust-lang/cargo/pull/12463)
- Preserve jobserver file descriptors on the rustc invocation for getting target information.
[#12447](https://github.com/rust-lang/cargo/pull/12447)
- Clarify in `--help` that `cargo test --all-targets` excludes doctests.
[#12422](https://github.com/rust-lang/cargo/pull/12422)
- Normalize `cargo.toml` to `Cargo.toml` on publish, and warn on other cases of `Cargo.toml`.
[#12399](https://github.com/rust-lang/cargo/pull/12399)
### Fixed
- Only skip mtime check on `~/.cargo/{git,registry}`.
[#12369](https://github.com/rust-lang/cargo/pull/12369)

[#12468](https://github.com/rust-lang/cargo/pull/12468)
- Fixed `cargo remove` incorrectly removing used patches.
[#12454](https://github.com/rust-lang/cargo/pull/12454)
- Fixed crate checksum lookup query should match on semver build metadata.
[#11447](https://github.com/rust-lang/cargo/pull/11447)
- Fixed printing multiple warning messages for unused fields in `[registries]` table.
[#12439](https://github.com/rust-lang/cargo/pull/12439)
### Nightly only
- 🔥 The `-Zcredential-process` has been reimplemented with a clearer way to
communicate with different credential providers. Several built-in providers
are also added to Cargo.

[#12492](https://github.com/rust-lang/cargo/pull/12492)
- Fixed invalid package names generated by `-Zscript`.
[#12349](https://github.com/rust-lang/cargo/pull/12349)
- `-Zscript` now errors out on unsupported commands — `publish` and `package`.

## Cargo 1.72 (2023-08-24)
[64fb38c9...rust-1.72.0](https://github.com/rust-lang/cargo/compare/64fb38c9...rust-1.72.0)
### Added
- ❗ Enable `-Zdoctest-in-workspace` by default. When running each documentation
test, the working directory is set to the root directory of the package the
test belongs to.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-test.html#working-directory-of-tests)
[#12221](https://github.com/rust-lang/cargo/pull/12221)
[#12288](https://github.com/rust-lang/cargo/pull/12288)
- Add support of the "default" keyword to reset previously set `build.jobs`
parallelism back to the default.
[#12222](https://github.com/rust-lang/cargo/pull/12222)
### Changed
- 🚨 [CVE-2023-40030](https://github.com/rust-lang/cargo/security/advisories/GHSA-wrrj-h57r-vx9p):
Malicious dependencies can inject arbitrary JavaScript into cargo-generated timing reports.
To mitigate this, feature name validation check is now turned into a hard error.
The warning was added in Rust 1.49. These extended characters aren't allowed on crates.io,
so this should only impact users of other registries, or people who don't publish to a registry.
[#12291](https://github.com/rust-lang/cargo/pull/12291)
- Cargo now warns when an edition 2021 package is in a virtual workspace and
`workspace.resolver` is not set. It is recommended to set the resolver
version for workspaces explicitly.
[#10910](https://github.com/rust-lang/cargo/pull/10910)
- Set IBM AIX shared libraries search path to `LIBPATH`.
[#11968](https://github.com/rust-lang/cargo/pull/11968)
- Don't pass `-C debuginfo=0` to rustc as it is the default value.
[#12022](https://github.com/rust-lang/cargo/pull/12022)
[#12205](https://github.com/rust-lang/cargo/pull/12205)
- Added a message on reusing previous temporary path on `cargo install` failures.
[#12231](https://github.com/rust-lang/cargo/pull/12231)
- Added a message when `rustup` override shorthand is put in a wrong position.
[#12226](https://github.com/rust-lang/cargo/pull/12226)
- Respect scp-like URL as much as possible when fetching nested submodules.
[#12359](https://github.com/rust-lang/cargo/pull/12359)
[#12411](https://github.com/rust-lang/cargo/pull/12411)
### Fixed
- `cargo clean` uses `remove_dir_all` as a fallback to resolve race conditions.
[#11442](https://github.com/rust-lang/cargo/pull/11442)
- Reduced the chance Cargo re-formats the user's `[features]` table.
[#12191](https://github.com/rust-lang/cargo/pull/12191)
- Fixed nested Git submodules not able to fetch.
[#12244](https://github.com/rust-lang/cargo/pull/12244)
### Nightly only
- 🔥 The `-Zscript` is an experimental feature to add unstable support for
single-file packages in Cargo, so we can explore the design and resolve
questions with an implementation to collect feedback on.
([eRFC 3424](https://github.com/rust-lang/rfcs/blob/master/text/3424-cargo-script.md))

## Cargo 1.71.1 (2023-08-03)
### Fixed
- 🚨 [CVE-2023-38497](https://github.com/rust-lang/cargo/security/advisories/GHSA-j3xp-wfr4-hx87):
Cargo 1.71.1 or later respects umask when extracting crate archives. It also
purges the caches it tries to access if they were generated by older Cargo versions.
## Cargo 1.71 (2023-07-13)
[84b7041f...rust-1.71.0](https://github.com/rust-lang/cargo/compare/84b7041f...rust-1.71.0)
### Added
- Allowed named debuginfo options in Cargo.toml.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#debug)
[#11958](https://github.com/rust-lang/cargo/pull/11958)
- Added `workspace_default_members` to the output of `cargo metadata`.
[#11978](https://github.com/rust-lang/cargo/pull/11978)
- Automatically inherit workspace fields when running `cargo new`/`cargo init`.
[#12069](https://github.com/rust-lang/cargo/pull/12069)
### Changed
- ❗ Optimized the usage under `rustup`. When Cargo detects it will run `rustc`
pointing a rustup proxy, it'll try bypassing the proxy and use the underlying
binary directly. There are assumptions around the interaction with rustup and
`RUSTUP_TOOLCHAIN`. However, it's not expected to affect normal users.
[#11917](https://github.com/rust-lang/cargo/pull/11917)
- ❗ When querying a package, Cargo tries only the original name, all hyphens,
and all underscores to handle misspellings. Previously, Cargo tried each
combination of hyphens and underscores, causing excessive requests to crates.io.
[#12083](https://github.com/rust-lang/cargo/pull/12083)
- ❗ Disallow `RUSTUP_HOME` and `RUSTUP_TOOLCHAIN` in the `[env]` configuration
table. This is considered to be not a use case Cargo would like to support,
since it will likely cause problems or lead to confusion.
[#12101](https://github.com/rust-lang/cargo/pull/12101)
[#12107](https://github.com/rust-lang/cargo/pull/12107)
- Better error message when getting an empty dependency table in Cargo.toml.
[#11997](https://github.com/rust-lang/cargo/pull/11997)
- Better error message when empty dependency was specified in Cargo.toml.
[#12001](https://github.com/rust-lang/cargo/pull/12001)
- `--help` text is now wrapping for readability on narrow screens.
[#12013](https://github.com/rust-lang/cargo/pull/12013)
- Tweaked the order of arguments in `--help` text to clarify role of `--bin`.
[#12157](https://github.com/rust-lang/cargo/pull/12157)
- `rust-version` is included in `cargo publish` requests to registries.
[#12041](https://github.com/rust-lang/cargo/pull/12041)
### Fixed
- Corrected the bug report URL for `cargo clippy --fix`.
[#11882](https://github.com/rust-lang/cargo/pull/11882)
- Cargo now applies `[env]` to rust invocations for target info discovery.
[#12029](https://github.com/rust-lang/cargo/pull/12029)
- Fixed tokens not redacted in http debug when using HTTP/2.

[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-logout.html)
[#11919](https://github.com/rust-lang/cargo/pull/11919)
[#11950](https://github.com/rust-lang/cargo/pull/11950)
- Added `--ignore-rust-version` flag to `cargo install`.
[#11859](https://github.com/rust-lang/cargo/pull/11859)
- The `CARGO_PKG_README` environment variable is now set to the path to the
README file when compiling a crate.
[#11645](https://github.com/rust-lang/cargo/pull/11645)
- Cargo now displays richer information of Cargo target failed to compile.
[#11636](https://github.com/rust-lang/cargo/pull/11636)
### Changed
- 🎉 The `sparse` protocol is now the default protocol for crates.io!
([RFC 2789](https://github.com/rust-lang/rfcs/blob/master/text/2789-sparse-index.md))
([docs](https://doc.rust-lang.org/nightly/cargo/reference/registries.html#registry-protocols))
[#11791](https://github.com/rust-lang/cargo/pull/11791)
[#11783](https://github.com/rust-lang/cargo/pull/11783)
- ❗ `cargo login` and `cargo logout` now uses the registry specified in
`registry.default`. This was an unintentional regression.
[#11949](https://github.com/rust-lang/cargo/pull/11949)
- `cargo update` accurately shows `Downgrading` status when downgrading dependencies.
[#11839](https://github.com/rust-lang/cargo/pull/11839)
- Added more information to HTTP errors to help with debugging.
[#11878](https://github.com/rust-lang/cargo/pull/11878)
- Added delays to network retries in Cargo.
[#11881](https://github.com/rust-lang/cargo/pull/11881)
- Refined `cargo publish` message when waiting for a publish complete.
[#11713](https://github.com/rust-lang/cargo/pull/11713)
- Better error message when `cargo install` from a git repository but found
multiple packages.
[#11835](https://github.com/rust-lang/cargo/pull/11835)
### Fixed
- Removed duplicates of possible values in `--charset` option of `cargo tree`.
[#11785](https://github.com/rust-lang/cargo/pull/11785)
- Fixed `CARGO_CFG_` vars for configs defined both with and without value.
[#11790](https://github.com/rust-lang/cargo/pull/11790)
- Broke endless loop on cyclic features in added dependency in `cargo add`.
[#11805](https://github.com/rust-lang/cargo/pull/11805)
- Don't panic when [`patch`] involved in dependency resolution results in a conflict.
[#11770](https://github.com/rust-lang/cargo/pull/11770)
- Fixed credential token format validation.
[#11951](https://github.com/rust-lang/cargo/pull/11951)

[#11824](https://github.com/rust-lang/cargo/pull/11824)
- `cargo new` generates the correct `.hgignore` aligning semantics with other
VCS ignore files.
[#11855](https://github.com/rust-lang/cargo/pull/11855)
- Stopped doing unnecessary fuzzy registry index queries. This significantly
reduces the amount of HTTP requests to remote registries for crates
containing `-` or `_` in their names.
[#11936](https://github.com/rust-lang/cargo/pull/11936)
[#11937](https://github.com/rust-lang/cargo/pull/11937)
### Nightly only
- Added `-Zdirect-minimal-versions`. This behaves like `-Zminimal-versions` but
only for direct dependencies.
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#direct-minimal-versions))
[#11688](https://github.com/rust-lang/cargo/pull/11688)
- Added `-Zgitoxide` which switches all `git fetch` operation in Cargo to
use `gitoxide` crate. This is still an MVP but could improve the performance
up to 2 times.
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html##gitoxide))

## Cargo 1.69 (2023-04-20)
[985d561f...rust-1.69.0](https://github.com/rust-lang/cargo/compare/985d561f...rust-1.69.0)
### Added
- Cargo now suggests `cargo fix` or `cargo clippy --fix`
when compilation warnings are auto-fixable.
[#11558](https://github.com/rust-lang/cargo/pull/11558)
- Cargo now suggests `cargo add` if you try to install a library crate.
[#11410](https://github.com/rust-lang/cargo/pull/11410)
- Cargo now sets the `CARGO_BIN_NAME` environment variable also for binary examples.
[#11705](https://github.com/rust-lang/cargo/pull/11705)
### Changed
- ❗ When `default-features` is set to false of a workspace dependency,
and an inherited dependency of a member has `default-features = true`,
Cargo will enable default features of that dependency.
[#11409](https://github.com/rust-lang/cargo/pull/11409)
- ❗ Deny `CARGO_HOME` in `[env]` configuration table. Cargo itself doesn't
pick up this value, but recursive calls to cargo would, which was not intended.
[#11644](https://github.com/rust-lang/cargo/pull/11644)
- ❗ Debuginfo for build dependencies is now off if not explicitly set. This is
expected to improve the overall build time.
[#11252](https://github.com/rust-lang/cargo/pull/11252)
- Cargo now emits errors on invalid alphanumeric characters in a registry token.
[#11600](https://github.com/rust-lang/cargo/pull/11600)

locate them.
[#11572](https://github.com/rust-lang/cargo/pull/11572)
- Fixed build scripts triggering recompiles when a `rerun-if-changed` points to
a directory whose mtime is not preserved by the filesystem.
[#11613](https://github.com/rust-lang/cargo/pull/11613)
- Fixed panics when using dependencies from `[workspace.dependencies]`
for `[patch]`. This usage is not supposed to be supported.
[#11565](https://github.com/rust-lang/cargo/pull/11565)
[#11630](https://github.com/rust-lang/cargo/pull/11630)

package doesn't directly interact with.
[#11643](https://github.com/rust-lang/cargo/pull/11643)
- Added `-C` flag for changing current dir before build starts.
[#10952](https://github.com/rust-lang/cargo/pull/10952)

## Cargo 1.68.2 (2023-03-28)
[115f3455...rust-1.68.0](https://github.com/rust-lang/cargo/compare/115f3455...rust-1.68.0)
- Updated the GitHub RSA SSH host key bundled within cargo.
The key was [rotated by
GitHub](https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/) on
2023-03-24 after the old one leaked.
[#11883](https://github.com/rust-lang/cargo/pull/11883)
- Added support for SSH known hosts marker `@revoked`.
[#11635](https://github.com/rust-lang/cargo/pull/11635)

### Added
- 🎉 Packages can now inherit settings from the workspace so that the settings
can be centralized in one place. See
[`workspace.package`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-package-table)
and
[`workspace.dependencies`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#the-dependencies-table)
for more details on how to define these common settings.
[#10859](https://github.com/rust-lang/cargo/pull/10859)
- Added the
[`--crate-type`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-rustc.html#option-cargo-rustc---crate-type)
flag to `cargo rustc` to override the crate type.
[#10838](https://github.com/rust-lang/cargo/pull/10838)
- Cargo commands can now accept multiple `--target` flags to build for
multiple targets at once, and the
[`build.target`](https://doc.rust-lang.org/nightly/cargo/reference/config.html#buildtarget)

to ensure that they use the same resolver when used in isolation.
[#10911](https://github.com/rust-lang/cargo/pull/10911)
[#10961](https://github.com/rust-lang/cargo/pull/10961)
[#10970](https://github.com/rust-lang/cargo/pull/10970)
- `cargo add` will now update `Cargo.lock`.
[#10902](https://github.com/rust-lang/cargo/pull/10902)

to forward slashes so that the settings should work across platforms.
[#10668](https://github.com/rust-lang/cargo/pull/10668)
- The
[`workspace.default-members`](https://doc.rust-lang.org/nightly/cargo/reference/workspaces.html#package-selection)
setting now allows a value of `"."` in a non-virtual workspace to refer to
the root package.
[#10784](https://github.com/rust-lang/cargo/pull/10784)
### Fixed
- 🚨 [CVE-2022-36113](https://github.com/rust-lang/cargo/security/advisories/GHSA-rfj2-q3h3-hm5j):

[#11089](https://github.com/rust-lang/cargo/pull/11089)
[#11088](https://github.com/rust-lang/cargo/pull/11088)
- 🚨 [CVE-2022-36114](https://github.com/rust-lang/cargo/security/advisories/GHSA-2hvr-h6gw-qrxp):
Extracting malicious crates can fill the file system.
[#11089](https://github.com/rust-lang/cargo/pull/11089)

happen when using `net.git-fetch-with-cli` and interrupting the clone
process.
[#10829](https://github.com/rust-lang/cargo/pull/10829)
- Fixed panic in `cargo add --offline`.
[#10817](https://github.com/rust-lang/cargo/pull/10817)
### Nightly only
- Fixed deserialization of unstable `check-cfg` in `config.toml`.
[#10799](https://github.com/rust-lang/cargo/pull/10799)
## Cargo 1.63 (2022-08-11)
[3f052d8e...rust-1.63.0](https://github.com/rust-lang/cargo/compare/3f052d8e...rust-1.63.0)

- A warning is emitted when encountering multiple packages with the same name
in a git dependency. This will ignore packages with `publish=false`.
[#10701](https://github.com/rust-lang/cargo/pull/10701)
[#10767](https://github.com/rust-lang/cargo/pull/10767)
- Change tracking now uses the contents of a `.json` target spec file instead
of its path. This should help avoid rebuilds if the path changes.
[#10746](https://github.com/rust-lang/cargo/pull/10746)
- Git dependencies with a submodule configured with the `update=none` strategy
in `.gitmodules` is now honored, and the submodule will not be fetched.
[#10717](https://github.com/rust-lang/cargo/pull/10717)
- Crate files now use a more recent date (Jul 23, 2006 instead of Nov 29, 1973)
for deterministic behavior.
[#10720](https://github.com/rust-lang/cargo/pull/10720)
- The initial template used for `cargo new` now includes a slightly more
realistic test structure that has `use super::*;` in the test module.
[#10706](https://github.com/rust-lang/cargo/pull/10706)
- Updated the internal HTTP library libcurl with various small fixes and updates.
[#10696](https://github.com/rust-lang/cargo/pull/10696)

[#10811](https://github.com/rust-lang/cargo/pull/10811)
- Fixed `-p` being ignored with `cargo publish` in the root of a virtual
workspace. Some additional checks were also added to generate an error if
multiple packages were selected (previously it would pick the first one).
[#10677](https://github.com/rust-lang/cargo/pull/10677)
- The human-readable executable name is no longer displayed for `cargo test`
when using JSON output.
[#10691](https://github.com/rust-lang/cargo/pull/10691)
### Nightly only
- Added `-Zcheck-cfg=output` to support build-scripts declaring their
supported set of `cfg` values with `cargo:rustc-check-cfg`.
[#10539](https://github.com/rust-lang/cargo/pull/10539)
- `-Z sparse-registry` now uses https://index.crates.io/ when accessing crates-io.
[#10725](https://github.com/rust-lang/cargo/pull/10725)
- Fixed formatting of `.workspace` key in `cargo add` for workspace inheritance.
[#10705](https://github.com/rust-lang/cargo/pull/10705)

## Cargo 1.62 (2022-06-30)
[1ef1e0a1...rust-1.62.0](https://github.com/rust-lang/cargo/compare/1ef1e0a1...rust-1.62.0)
### Added
- 🎉 Added the `cargo add` command for adding dependencies to `Cargo.toml` from
the command-line.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-add.html)
[#10472](https://github.com/rust-lang/cargo/pull/10472)
[#10577](https://github.com/rust-lang/cargo/pull/10577)
[#10578](https://github.com/rust-lang/cargo/pull/10578)
- Package ID specs now support `name@version` syntax in addition to the
previous `name:version` to align with the behavior in `cargo add` and other
tools. `cargo install` and `cargo yank` also now support this syntax so the
version does not need to passed as a separate flag.
[#10582](https://github.com/rust-lang/cargo/pull/10582)
[#10650](https://github.com/rust-lang/cargo/pull/10650)
[#10597](https://github.com/rust-lang/cargo/pull/10597)
- Added the CLI option `-F` as an alias of `--features`.
[#10576](https://github.com/rust-lang/cargo/pull/10576)
- The `git` and `registry` directories in Cargo's home directory (usually
`~/.cargo`) are now marked as cache directories so that they are not
included in backups or content indexing (on Windows).
[#10553](https://github.com/rust-lang/cargo/pull/10553)
- Added the `--version` flag to `cargo yank` to replace the `--vers` flag to
be consistent with `cargo install`.
[#10575](https://github.com/rust-lang/cargo/pull/10575)
- Added automatic `@` argfile support, which will use "response files" if the
command-line to `rustc` exceeds the operating system's limit.
[#10546](https://github.com/rust-lang/cargo/pull/10546)
- `cargo clean` now has a progress bar (if it takes longer than half a second).
[#10236](https://github.com/rust-lang/cargo/pull/10236)
### Changed
- `cargo install` no longer generates an error if no binaries were found
to install (such as missing required features).
[#10508](https://github.com/rust-lang/cargo/pull/10508)
- `cargo test` now passes `--target` to `rustdoc` if the specified target is
the same as the host target.
[#10594](https://github.com/rust-lang/cargo/pull/10594)
- `cargo doc` now automatically passes `-Arustdoc::private-intra-doc-links`
when documenting a binary (which automatically includes
`--document-private-items`). The
[`private-intra-doc-links`](https://doc.rust-lang.org/rustdoc/lints.html#private_intra_doc_links)
lint is only relevant when *not* documenting private items, which doesn't
apply to binaries.
[#10142](https://github.com/rust-lang/cargo/pull/10142)
- The length of the short git hash in the `cargo --version` output is now
fixed to 9 characters. Previously the length was inconsistent between
different platforms.
[#10579](https://github.com/rust-lang/cargo/pull/10579)
- Attempting to publish a package with a `Cargo.toml.orig` file will now
result in an error. The filename would otherwise conflict with the
automatically-generated file.
[#10551](https://github.com/rust-lang/cargo/pull/10551)
### Fixed
- The `build.dep-info-basedir` configuration setting now properly supports the
use of `..` in the path to refer to a parent directory.
[#10281](https://github.com/rust-lang/cargo/pull/10281)
- Fixed regression in automatic detection of the default number of CPUs to use
on systems using cgroups v1.
[#10737](https://github.com/rust-lang/cargo/pull/10737)
[#10739](https://github.com/rust-lang/cargo/pull/10739)
### Nightly only
- `cargo fetch` now works with `-Zbuild-std` to fetch the standard library's dependencies.
[#10129](https://github.com/rust-lang/cargo/pull/10129)
- Added support for workspace inheritance.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#workspace-inheritance)

[#10548](https://github.com/rust-lang/cargo/pull/10548)
[#10538](https://github.com/rust-lang/cargo/pull/10538)
- Added `-Zcheck-cfg` which adds various forms of validating `cfg` expressions
for unknown names and values.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#check-cfg)
[#10486](https://github.com/rust-lang/cargo/pull/10486)
[#10566](https://github.com/rust-lang/cargo/pull/10566)
- The `--config` CLI option no longer allows setting a registry token.
[#10580](https://github.com/rust-lang/cargo/pull/10580)
- Fixed issues with proc-macros and `-Z rustdoc-scrape-examples`.
[#10549](https://github.com/rust-lang/cargo/pull/10549)
[#10533](https://github.com/rust-lang/cargo/pull/10533)

[#10346](https://github.com/rust-lang/cargo/pull/10346)
- `cargo tree --duplicates` no longer reports dependencies that are shared
between the host and the target as duplicates.
[#10466](https://github.com/rust-lang/cargo/pull/10466)
- Updated to the 1.4.2 release of libgit2 which brings in several fixes

[#10479](https://github.com/rust-lang/cargo/pull/10479)
- `cargo vendor` no longer allows multiple values for `--sync`, you must pass
multiple `--sync` flags instead.
[#10448](https://github.com/rust-lang/cargo/pull/10448)
- Warnings are now issued for manifest keys that have mixed both underscore
and dash variants (such as specifying both `proc_macro` and `proc-macro`)
[#10316](https://github.com/rust-lang/cargo/pull/10316)
- Cargo now uses the standard library's `available_parallelism` instead of the
`num_cpus` crate for determining the default parallelism.
[#10427](https://github.com/rust-lang/cargo/pull/10427)
- `cargo search` terms are now highlighted.
[#10425](https://github.com/rust-lang/cargo/pull/10425)

conflict with VCS flags.
[#10483](https://github.com/rust-lang/cargo/pull/10483)
- Fixed the `http.timeout` configuration value to actually work.
[#10456](https://github.com/rust-lang/cargo/pull/10456)
- Fixed issues with `cargo rustc --crate-type` not working in some situations.
[#10388](https://github.com/rust-lang/cargo/pull/10388)
### Nightly only
- Added `-Z check-cfg-features` to enable compile-time checking of features
[#10408](https://github.com/rust-lang/cargo/pull/10408)

## Cargo 1.60 (2022-04-07)
[358e79fe...rust-1.60.0](https://github.com/rust-lang/cargo/compare/358e79fe...rust-1.60.0)
### Added
- 🎉 Added the `dep:` prefix in the `[features]` table to refer to an optional
dependency. This allows creating feature names with the same name as a
dependency, and allows for "hiding" optional dependencies so that they do
not implicitly expose a feature name.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/features.html#optional-dependencies)
[#10269](https://github.com/rust-lang/cargo/pull/10269)
- 🎉 Added the `dep-name?/feature-name` syntax to the `[features]` table to
only enable the feature `feature-name` if the optional dependency `dep-name`
is already enabled by some other feature.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/features.html#dependency-features)
[#10269](https://github.com/rust-lang/cargo/pull/10269)
- 🎉 Added `--timings` option to generate an HTML report about build timing,
concurrency, and CPU use.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/timings.html)
[#10245](https://github.com/rust-lang/cargo/pull/10245)
- Added the `"v"` and `"features2"` fields to the registry index.
The `"v"` field provides a method for compatibility with future changes to the index.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/registries.html#index-format)
[#10269](https://github.com/rust-lang/cargo/pull/10269)
- Added bash completion for `cargo clippy`
[#10347](https://github.com/rust-lang/cargo/pull/10347)
- Added bash completion for `cargo report`
[#10295](https://github.com/rust-lang/cargo/pull/10295)
- Added support to build scripts for `rustc-link-arg-tests`,
`rustc-link-arg-examples`, and `rustc-link-arg-benches`.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/build-scripts.html#outputs-of-the-build-script)
[#10274](https://github.com/rust-lang/cargo/pull/10274)

always be enabled.
[#10258](https://github.com/rust-lang/cargo/pull/10258)
- `cargo new` will now generate a `.gitignore` which only ignores `Cargo.lock`
in the root of the repo, instead of any directory.
[#10379](https://github.com/rust-lang/cargo/pull/10379)
- Improved startup time of bash completion.
[#10365](https://github.com/rust-lang/cargo/pull/10365)
- The `--features` flag is now honored when used with the `--all-features`
flag, which allows enabling features from other packages.
[#10337](https://github.com/rust-lang/cargo/pull/10337)
- Cargo now uses a different TOML parser. This should not introduce any
user-visible changes. This paves the way to support format-preserving
programmatic modification of TOML files for supporting `cargo add` and other
future enhancements.
[#10086](https://github.com/rust-lang/cargo/pull/10086)
- Setting a library to emit both a `dylib` and `cdylib` is now an error, as
this combination is not supported.
[#10243](https://github.com/rust-lang/cargo/pull/10243)
- `cargo --list` now includes the `help` command.
[#10300](https://github.com/rust-lang/cargo/pull/10300)

This provides reporting for when a future change in `rustc` may cause a
package or any of its dependencies to stop building.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/future-incompat-report.html)
[#10165](https://github.com/rust-lang/cargo/pull/10165)
- SSH authentication on Windows now supports ssh-agent.
[docs](https://doc.rust-lang.org/nightly/cargo/appendix/git-authentication.html#ssh-authentication)
[#10248](https://github.com/rust-lang/cargo/pull/10248)
- Added `term.quiet` configuration option to enable the `--quiet` behavior
from a config file.

[#10152](https://github.com/rust-lang/cargo/pull/10152)
- Added `-r` CLI option as an alias for `--release`.
[#10133](https://github.com/rust-lang/cargo/pull/10133)
### Changed
- Scanning the package directory should now be resilient to errors, such as
filesystem loops or access issues.
[#10188](https://github.com/rust-lang/cargo/pull/10188)
[#10214](https://github.com/rust-lang/cargo/pull/10214)
[#10286](https://github.com/rust-lang/cargo/pull/10286)
- `cargo help <alias>` will now show the target of the alias.
[#10193](https://github.com/rust-lang/cargo/pull/10193)
- Removed the deprecated `--host` CLI option.
[#10145](https://github.com/rust-lang/cargo/pull/10145)
[#10327](https://github.com/rust-lang/cargo/pull/10327)
- Cargo should now report its version to always be in sync with `rustc`.
[#10178](https://github.com/rust-lang/cargo/pull/10178)
- Added EOPNOTSUPP to ignored file locking errors, which is relevant to BSD
operating systems.
[#10157](https://github.com/rust-lang/cargo/pull/10157)
### Fixed
- macOS: Fixed an issue where running an executable would sporadically be
killed by the kernel (likely starting in macOS 12).
[#10196](https://github.com/rust-lang/cargo/pull/10196)
- Fixed so that the `doc=false` setting is honored in the `[lib]` definition
of a dependency.
[#10201](https://github.com/rust-lang/cargo/pull/10201)
[#10324](https://github.com/rust-lang/cargo/pull/10324)
- The `"executable"` field in the JSON option was incorrectly including the
path to `index.html` when documenting a binary. It is now null.
[#10171](https://github.com/rust-lang/cargo/pull/10171)
- Documenting a binary now waits for the package library to finish documenting
before starting. This fixes some race conditions if the binary has intra-doc
links to the library.
[#10172](https://github.com/rust-lang/cargo/pull/10172)
- Fixed panic when displaying help text to a closed pipe.
[#10164](https://github.com/rust-lang/cargo/pull/10164)

[#10103](https://github.com/rust-lang/cargo/pull/10103)
- Fixed `cargo clean -p` when the directory path contains glob characters.
[#10072](https://github.com/rust-lang/cargo/pull/10072)
- Fixed debug builds of `cargo` which could panic when downloading a crate
when the server has a redirect with a non-empty body.
[#10048](https://github.com/rust-lang/cargo/pull/10048)
### Nightly only
- Make future-incompat-report output more user-friendly.
[#9953](https://github.com/rust-lang/cargo/pull/9953)

[#10024](https://github.com/rust-lang/cargo/pull/10024)
## Cargo 1.57 (2021-12-02)
[18751dd3...rust-1.57.0](https://github.com/rust-lang/cargo/compare/18751dd3...rust-1.57.0)
### Added
- 🎉 Added custom named profiles. This also changes the `test` and `bench`
profiles to inherit their settings from `dev` and `release`, and Cargo will
now only use a single profile during a given command instead of using
different profiles for dependencies and cargo-targets.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#custom-profiles)
[#9943](https://github.com/rust-lang/cargo/pull/9943)
- The `rev` option for a git dependency now supports git references that start
with `refs/`. An example where this can be used is to depend on a pull
request from a service like GitHub before it is merged.
[#9859](https://github.com/rust-lang/cargo/pull/9859)
- Added `path_in_vcs` field to the `.cargo_vcs_info.json` file.

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

### Fixed
- Removed a log message (from `CARGO_LOG`) that may leak tokens.
[#9873](https://github.com/rust-lang/cargo/pull/9873)
- `cargo fix` will now avoid writing fixes to the global registry cache.
[#9938](https://github.com/rust-lang/cargo/pull/9938)
- Fixed `-Z help` CLI option when used with a shorthand alias (b/c/r/d).
[#9933](https://github.com/rust-lang/cargo/pull/9933)

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

[#9808](https://github.com/rust-lang/cargo/pull/9808)
- 🎉 Build scripts can now pass additional linker arguments for binaries or all
linkable targets. [docs](https://doc.rust-lang.org/nightly/cargo/reference/build-scripts.html#outputs-of-the-build-script)
[#9557](https://github.com/rust-lang/cargo/pull/9557)
- Added support for the `-p` flag for `cargo publish` to publish a specific
package in a workspace. `cargo package` also now supports `-p` and
`--workspace`.

### Changed
- Doc tests now support the `-q` flag to show terse test output.
[#9730](https://github.com/rust-lang/cargo/pull/9730)
- `features` used in a `[replace]` table now issues a warning, as they are ignored.
[#9681](https://github.com/rust-lang/cargo/pull/9681)
- Changed so that only `wasm32-unknown-emscripten` executables are built
without a hash in the filename. Previously it was all `wasm32` targets.
Additionally, all `apple` binaries are now built with a hash in the
filename. This allows multiple copies to be cached at once, and matches the
behavior on other platforms (except `msvc`).
[#9653](https://github.com/rust-lang/cargo/pull/9653)
- `cargo new` now generates an example that doesn't generate a warning with
clippy.
[#9796](https://github.com/rust-lang/cargo/pull/9796)

environment variable.
[#9831](https://github.com/rust-lang/cargo/pull/9831)
- Changed `cargo fix --edition` to emit a warning when on the latest stable
edition when running on stable instead of generating an error.
[#9792](https://github.com/rust-lang/cargo/pull/9792)
- `cargo install` will now determine all of the packages to install before
starting the installation, which should help with reporting errors without
partially installing.
[#9793](https://github.com/rust-lang/cargo/pull/9793)
- The resolver report for `cargo fix --edition` now includes differences for
dev-dependencies.
[#9803](https://github.com/rust-lang/cargo/pull/9803)
- `cargo fix` will now show better diagnostics for abnormal errors from `rustc`.
[#9799](https://github.com/rust-lang/cargo/pull/9799)

[#9773](https://github.com/rust-lang/cargo/pull/9773)
- Aliases are now included in `cargo --list`.
[#9764](https://github.com/rust-lang/cargo/pull/9764)
### Fixed
- Fixed panic with build-std of a proc-macro.
[#9834](https://github.com/rust-lang/cargo/pull/9834)
- Fixed running `cargo` recursively from proc-macros while running `cargo fix`.
[#9818](https://github.com/rust-lang/cargo/pull/9818)
- Return an error instead of a stack overflow for command alias loops.
[#9791](https://github.com/rust-lang/cargo/pull/9791)
- Updated to curl 7.79.1, which will hopefully fix intermittent http2 errors.
[#9937](https://github.com/rust-lang/cargo/pull/9937)

non-rust-identifier for a binary name.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#different-binary-name)
[#9627](https://github.com/rust-lang/cargo/pull/9627)
- Added a profile option to select the codegen backend.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#codegen-backend)
[#9118](https://github.com/rust-lang/cargo/pull/9118)
## Cargo 1.55 (2021-09-09)
[aa8b0929...rust-1.55.0](https://github.com/rust-lang/cargo/compare/aa8b0929...rust-1.55.0)
### Added
- The package definition in `cargo metadata` now includes the `"default_run"`
field from the manifest.
[#9550](https://github.com/rust-lang/cargo/pull/9550)
- ❗ Build scripts now have access to the following environment variables:
`RUSTC_WRAPPER`, `RUSTC_WORKSPACE_WRAPPER`, `CARGO_ENCODED_RUSTFLAGS`.
`RUSTFLAGS` is no longer set for build scripts; they should use
`CARGO_ENCODED_RUSTFLAGS` instead.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-build-scripts)
[#9601](https://github.com/rust-lang/cargo/pull/9601)
- Added `cargo d` as an alias for `cargo doc`.
[#9680](https://github.com/rust-lang/cargo/pull/9680)

- Added `members_mut` method to the `Workspace` API.
[#9547](https://github.com/rust-lang/cargo/pull/9547)
### Changed
- If a build command does not match any targets when using the
`--all-targets`, `--bins`, `--tests`, `--examples`, or `--benches` flags, a
warning is now displayed to inform you that there were no matching targets.
[#9549](https://github.com/rust-lang/cargo/pull/9549)
- The way `cargo init` detects whether or not existing source files represent
a binary or library has been changed to respect the command-line flags
instead of trying to guess which type it is.
[#9522](https://github.com/rust-lang/cargo/pull/9522)
- Registry names are now displayed instead of registry URLs when possible.
[#9632](https://github.com/rust-lang/cargo/pull/9632)
- Duplicate compiler diagnostics are no longer shown. This can often happen
with `cargo test` which builds multiple copies of the same code in parallel.
This also updates the warning summary to provide more context.
[#9675](https://github.com/rust-lang/cargo/pull/9675)
- The output for warnings or errors is now improved to be leaner, cleaner, and
show more context.
[#9655](https://github.com/rust-lang/cargo/pull/9655)
- Network send errors are now treated as "spurious" which means they will be retried.
[#9695](https://github.com/rust-lang/cargo/pull/9695)
- Git keys (`branch`, `tag`, `rev`) on a non-git dependency are now an error.
Additionally, specifying both `git` and `path` is now an error.
[#9689](https://github.com/rust-lang/cargo/pull/9689)
- Specifying a dependency without any keys is now an error.
[#9686](https://github.com/rust-lang/cargo/pull/9686)
- The resolver now prefers to use `[patch]` table entries of dependencies when
possible.
[#9639](https://github.com/rust-lang/cargo/pull/9639)
- Package name typo errors in dependencies are now displayed aligned with the
original to help make it easier to see the difference.
[#9665](https://github.com/rust-lang/cargo/pull/9665)
- Windows platforms may now warn on environment variables that have the wrong case.
[#9654](https://github.com/rust-lang/cargo/pull/9654)

[#9635](https://github.com/rust-lang/cargo/pull/9635)
- When `Cargo.toml` is not found, the error message now detects if it was
misnamed with a lowercase `c` to suggest the correct form.
[#9607](https://github.com/rust-lang/cargo/pull/9607)
- Building `diesel` with the new resolver displays a compatibility notice.
[#9602](https://github.com/rust-lang/cargo/pull/9602)

- Implement warning for ignored trailing arguments after `--`
[#9561](https://github.com/rust-lang/cargo/pull/9561)
- Fixed rustc/rustdoc config values to be config-relative.
[#9566](https://github.com/rust-lang/cargo/pull/9566)
- `cargo fix` now supports rustc's suggestions with multiple spans.
[#9567](https://github.com/rust-lang/cargo/pull/9567)
- `cargo fix` now fixes each target serially instead of in parallel to avoid
problems with fixing the same file concurrently.
[#9677](https://github.com/rust-lang/cargo/pull/9677)
- Changes to the target `linker` config value now trigger a rebuild.
[#9647](https://github.com/rust-lang/cargo/pull/9647)
- Git unstaged deleted files are now ignored when using the `--allow-dirty`
flag with `cargo publish` or `cargo package`.

[#9473](https://github.com/rust-lang/cargo/pull/9473)
- Added `CARGO_TARGET_TMPDIR` environment variable set for integration tests &
benches. This provides a temporary or "scratch" directory in the `target`
directory for tests and benches to use.
[#9375](https://github.com/rust-lang/cargo/pull/9375)
### Changed
- `--features` CLI flags now provide typo suggestions with the new feature resolver.
[#9420](https://github.com/rust-lang/cargo/pull/9420)
- Cargo now uses a new parser for SemVer versions. This should behave mostly
the same as before with some minor exceptions where invalid syntax for
version requirements is now rejected.
[#9508](https://github.com/rust-lang/cargo/pull/9508)
- Mtime handling of `.crate` published packages has changed slightly to avoid
mtime values of 0. This was causing problems with lldb which refused to read
those files.
[#9517](https://github.com/rust-lang/cargo/pull/9517)
- Improved performance of git status check in `cargo package`.
[#9478](https://github.com/rust-lang/cargo/pull/9478)
- `cargo new` with fossil now places the ignore settings in the new repository
instead of using `fossil settings` to set them globally. This also includes
several other cleanups to make it more consistent with other VCS
configurations.
[#9469](https://github.com/rust-lang/cargo/pull/9469)
- `rustc-cdylib-link-arg` applying transitively displays a warning that this
was not intended, and may be an error in the future.
[#9563](https://github.com/rust-lang/cargo/pull/9563)
### Fixed
- Fixed `package.exclude` in `Cargo.toml` using inverted exclusions
(`!somefile`) when not in a git repository or when vendoring a dependency.
[#9186](https://github.com/rust-lang/cargo/pull/9186)
- Dep-info files now adjust build script `rerun-if-changed` paths to be
absolute paths.
[#9421](https://github.com/rust-lang/cargo/pull/9421)
- Fixed a bug when with resolver = "1" non-virtual package was allowing
unknown features.
[#9437](https://github.com/rust-lang/cargo/pull/9437)
- Fixed an issue with the index cache mishandling versions that only
differed in build metadata (such as `110.0.0` and `110.0.0+1.1.0f`).
[#9476](https://github.com/rust-lang/cargo/pull/9476)
- Fixed `cargo install` with a semver metadata version.
[#9467](https://github.com/rust-lang/cargo/pull/9467)
### Nightly only
- Added `report` subcommand, and changed `cargo
describe-future-incompatibilitie` to `cargo report
future-incompatibilities`.
[#9438](https://github.com/rust-lang/cargo/pull/9438)

host target. Also added `target-applies-to-host` to control how the
`[target]` tables behave.
[#9322](https://github.com/rust-lang/cargo/pull/9322)
- Added some validation to build script `rustc-link-arg-*` instructions to
return an error if the target doesn't exist.
[#9523](https://github.com/rust-lang/cargo/pull/9523)
- Added `cargo:rustc-link-arg-bin` instruction for build scripts.
[#9486](https://github.com/rust-lang/cargo/pull/9486)
## Cargo 1.53 (2021-06-17)
[90691f2b...rust-1.53.0](https://github.com/rust-lang/cargo/compare/90691f2b...rust-1.53.0)
### Added
### Changed
- 🔥 Cargo now supports git repositories where the default `HEAD` branch is not
"master". This also includes a switch to the version 3 `Cargo.lock` format

the search index) that can become broken when using different versions.
[#8640](https://github.com/rust-lang/cargo/pull/8640)
[#9404](https://github.com/rust-lang/cargo/pull/9404)
- Improved error messages when path dependency/workspace member is missing.

- Fixed the `-C metadata` value to always include all information for all
builds. Previously, in some situations, the hash only included the package
name and version. This fixes some issues, such as incremental builds with
split-debuginfo on macOS corrupting the incremental cache in some cases.
[#9418](https://github.com/rust-lang/cargo/pull/9418)
- Fixed man pages not working on Windows if `man` is in `PATH`.
[#9378](https://github.com/rust-lang/cargo/pull/9378)
- The `rustc` cache is now aware of `RUSTC_WRAPPER` and `RUSTC_WORKSPACE_WRAPPER`.
[#9348](https://github.com/rust-lang/cargo/pull/9348)
- Track the `CARGO` environment variable in the rebuild fingerprint if the
code uses `env!("CARGO")`.
[#9363](https://github.com/rust-lang/cargo/pull/9363)
### Nightly only
- Fixed config includes not working.
[#9299](https://github.com/rust-lang/cargo/pull/9299)
- Emit note when `--future-incompat-report` had nothing to report.
[#9263](https://github.com/rust-lang/cargo/pull/9263)
- Error messages for nightly features flags (like `-Z` and `cargo-features`)
now provides more information.
[#9290](https://github.com/rust-lang/cargo/pull/9290)
- Added the ability to set the target for an individual package in `Cargo.toml`.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#per-package-target)
[#9030](https://github.com/rust-lang/cargo/pull/9030)
- Fixed build-std updating the index on every build.
[#9393](https://github.com/rust-lang/cargo/pull/9393)
- `-Z help` now displays all the `-Z` options.
[#9369](https://github.com/rust-lang/cargo/pull/9369)

- An error is now reported if `CARGO_TARGET_DIR` is an empty string.
[#8939](https://github.com/rust-lang/cargo/pull/8939)
- Doc tests now pass the `--message-format` flag into the test so that the
"short" format can now be used for doc tests.
[#9128](https://github.com/rust-lang/cargo/pull/9128)
- `cargo test` now prints a clearer indicator of which target is currently running.
[#9195](https://github.com/rust-lang/cargo/pull/9195)
- The `CARGO_TARGET_<TRIPLE>` environment variable will now issue a warning if
it is using lowercase letters.
[#9169](https://github.com/rust-lang/cargo/pull/9169)
### Fixed
- Fixed publication of packages with metadata and resolver fields in `Cargo.toml`.
[#9300](https://github.com/rust-lang/cargo/pull/9300)
[#9304](https://github.com/rust-lang/cargo/pull/9304)
- Fixed logic for determining prefer-dynamic for a dylib which differed in a
workspace vs a single package.
[#9252](https://github.com/rust-lang/cargo/pull/9252)
- Fixed an issue where exclusive target-specific dependencies that overlapped
across dependency kinds (like regular and build-dependencies) would
incorrectly include the dependencies in both.
[#9255](https://github.com/rust-lang/cargo/pull/9255)
- Fixed panic with certain styles of Package IDs when passed to the `-p` flag.
[#9188](https://github.com/rust-lang/cargo/pull/9188)
- When running cargo with output not going to a TTY, and with the progress bar
and color force-enabled, the output will now correctly clear the progress
line.
[#9231](https://github.com/rust-lang/cargo/pull/9231)
- Error instead of panic when JSON may contain non-utf8 paths.
[#9226](https://github.com/rust-lang/cargo/pull/9226)
- Fixed a hang that can happen on broken stderr.
[#9201](https://github.com/rust-lang/cargo/pull/9201)
- Fixed thin-local LTO not being disabled correctly when `lto=off` is set.
[#9182](https://github.com/rust-lang/cargo/pull/9182)

information from rustc.
[#9002](https://github.com/rust-lang/cargo/pull/9002)
- Added `-Zdoctest-in-workspace` for changing the directory where doctests are
*run* versus where they are *compiled*.
[#9105](https://github.com/rust-lang/cargo/pull/9105)

## Cargo 1.51 (2021-03-25)
[75d5d8cf...rust-1.51.0](https://github.com/rust-lang/cargo/compare/75d5d8cf...rust-1.51.0)
### Added
- 🔥 Added the `split-debuginfo` profile option.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#split-debuginfo)
[#9112](https://github.com/rust-lang/cargo/pull/9112)
- Added the `path` field to `cargo metadata` for the package dependencies list
to show the path for "path" dependencies.
[#8994](https://github.com/rust-lang/cargo/pull/8994)
- 🔥 Added a new feature resolver, and new CLI feature flag behavior. See the
new [features](https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2)
and [resolver](https://doc.rust-lang.org/nightly/cargo/reference/resolver.html#feature-resolver-version-2)
documentation for the `resolver = "2"` option. See the
[CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#command-line-feature-options)
and [resolver 2 CLI](https://doc.rust-lang.org/nightly/cargo/reference/features.html#resolver-version-2-command-line-flags)
options for the new CLI behavior. And, finally, see
[RFC 2957](https://github.com/rust-lang/rfcs/blob/master/text/2957-cargo-features2.md)
for a detailed look at what has changed.
[#8997](https://github.com/rust-lang/cargo/pull/8997)
### Changed
- `cargo install --locked` now emits a warning if `Cargo.lock` is not found.
[#9108](https://github.com/rust-lang/cargo/pull/9108)
- Unknown or ambiguous package IDs passed on the command-line now display
suggestions for the correct package ID.
[#9095](https://github.com/rust-lang/cargo/pull/9095)
- Slightly optimize `cargo vendor`
[#8937](https://github.com/rust-lang/cargo/pull/8937)
[#9131](https://github.com/rust-lang/cargo/pull/9131)
[#9132](https://github.com/rust-lang/cargo/pull/9132)
### Fixed
- Fixed environment variables and cfg settings emitted by a build script that
are set for `cargo test` and `cargo run` when the build script runs multiple
times during the same build session.
[#9122](https://github.com/rust-lang/cargo/pull/9122)
- Fixed a panic with `cargo doc` and the new feature resolver. This also
introduces some heuristics to try to avoid path collisions with `rustdoc` by
only documenting one variant of a package if there are multiple (such as
multiple versions, or the same package shared for host and target
platforms).
[#9077](https://github.com/rust-lang/cargo/pull/9077)
- Fixed a bug in Cargo's cyclic dep graph detection that caused a stack
overflow.
[#9075](https://github.com/rust-lang/cargo/pull/9075)
- Fixed build script `links` environment variables (`DEP_*`) not showing up
for testing packages in some cases.
[#9065](https://github.com/rust-lang/cargo/pull/9065)
- Fixed features being selected in a nondeterministic way for a specific
scenario when building an entire workspace with all targets with a
proc-macro in the workspace with `resolver="2"`.
[#9059](https://github.com/rust-lang/cargo/pull/9059)
- Fixed to use `http.proxy` setting in `~/.gitconfig`.
[#8986](https://github.com/rust-lang/cargo/pull/8986)
- Fixed --feature pkg/feat for V1 resolver for non-member.
[#9275](https://github.com/rust-lang/cargo/pull/9275)
[#9277](https://github.com/rust-lang/cargo/pull/9277)
- Fixed panic in `cargo doc` when there are colliding output filenames in a workspace.
[#9276](https://github.com/rust-lang/cargo/pull/9276)
[#9277](https://github.com/rust-lang/cargo/pull/9277)
- Fixed `cargo install` from exiting with success if one of several packages
did not install successfully.
[#9185](https://github.com/rust-lang/cargo/pull/9185)
[#9196](https://github.com/rust-lang/cargo/pull/9196)
- Fix panic with doc collision orphan.
[#9142](https://github.com/rust-lang/cargo/pull/9142)
[#9196](https://github.com/rust-lang/cargo/pull/9196)
### Nightly only
- Removed the `publish-lockfile` unstable feature, it was stabilized without
the need for an explicit flag 1.5 years ago.
[#9092](https://github.com/rust-lang/cargo/pull/9092)
- Added better diagnostics, help messages, and documentation for nightly
features (such as those passed with the `-Z` flag, or specified with
`cargo-features` in `Cargo.toml`).
[#9092](https://github.com/rust-lang/cargo/pull/9092)
- Added support for Rust edition 2021.
[#8922](https://github.com/rust-lang/cargo/pull/8922)
- Added support for the `rust-version` field in project metadata.
[#8037](https://github.com/rust-lang/cargo/pull/8037)
- Added a schema field to the index.
[#9161](https://github.com/rust-lang/cargo/pull/9161)
[#9196](https://github.com/rust-lang/cargo/pull/9196)
## Cargo 1.50 (2021-02-11)
[8662ab42...rust-1.50.0](https://github.com/rust-lang/cargo/compare/8662ab42...rust-1.50.0)
### Added
- Added the `doc` field to `cargo metadata`, which indicates if a target is
documented.
[#8869](https://github.com/rust-lang/cargo/pull/8869)
- Added `RUSTC_WORKSPACE_WRAPPER`, an alternate RUSTC wrapper that only runs
for the local workspace packages, and caches its artifacts independently of
non-wrapped builds.
[#8976](https://github.com/rust-lang/cargo/pull/8976)
- Added `--workspace` to `cargo update` to update only the workspace members,
and not their dependencies. This is particularly useful if you update the
version in `Cargo.toml` and want to update `Cargo.lock` without running any
other commands.
[#8725](https://github.com/rust-lang/cargo/pull/8725)
### Changed
- `.crate` files uploaded to a registry are now built with reproducible
settings, so that the same `.crate` file created on different machines
should be identical.
[#8864](https://github.com/rust-lang/cargo/pull/8864)
- Git dependencies that specify more than one of `branch`, `tag`, or `rev` are
now rejected.
[#8984](https://github.com/rust-lang/cargo/pull/8984)
- The `rerun-if-changed` build script directive can now point to a directory,
in which case Cargo will check if any file in that directory changes.
[#8973](https://github.com/rust-lang/cargo/pull/8973)
- If Cargo cannot determine the username or email address, `cargo new` will no
longer fail, and instead create an empty authors list.
[#8912](https://github.com/rust-lang/cargo/pull/8912)
- The progress bar width has been reduced to provide more room to display the
crates currently being built.
[#8892](https://github.com/rust-lang/cargo/pull/8892)
- `cargo new` will now support `includeIf` directives in `.gitconfig` to match
the correct directory when determining the username and email address.
[#8886](https://github.com/rust-lang/cargo/pull/8886)
### Fixed
- Fixed `cargo metadata` and `cargo tree` to only download packages for the
requested target.
[#8987](https://github.com/rust-lang/cargo/pull/8987)
- Updated libgit2, which brings in many fixes, particularly fixing a zlib
error that occasionally appeared on 32-bit systems.
[#8998](https://github.com/rust-lang/cargo/pull/8998)
- Fixed stack overflow with a circular dev-dependency that uses the `links`
field.
[#8969](https://github.com/rust-lang/cargo/pull/8969)
- Fixed `cargo publish` failing on some filesystems, particularly 9p on WSL2.
[#8950](https://github.com/rust-lang/cargo/pull/8950)
### Nightly only
- Allow `resolver="1"` to specify the original feature resolution behavior.
[#8857](https://github.com/rust-lang/cargo/pull/8857)
- Added `-Z extra-link-arg` which adds the `cargo:rustc-link-arg-bins`
and `cargo:rustc-link-arg` build script options.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#extra-link-arg)
[#8441](https://github.com/rust-lang/cargo/pull/8441)
- Implemented external credential process support, and added `cargo logout`.
([RFC 2730](https://github.com/rust-lang/rfcs/blob/master/text/2730-cargo-token-from-process.md))
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#credential-process))
[#8934](https://github.com/rust-lang/cargo/pull/8934)
- Fix panic with `-Zbuild-std` and no roots.
[#8942](https://github.com/rust-lang/cargo/pull/8942)
- Set docs.rs as the default extern-map for crates.io
[#8877](https://github.com/rust-lang/cargo/pull/8877)
## Cargo 1.49 (2020-12-31)
[75615f8e...rust-1.49.0](https://github.com/rust-lang/cargo/compare/75615f8e...rust-1.49.0)
### Added
- Added `homepage` and `documentation` fields to `cargo metadata`.
[#8744](https://github.com/rust-lang/cargo/pull/8744)
- Added the `CARGO_PRIMARY_PACKAGE` environment variable which is set when
running `rustc` if the package is one of the "root" packages selected on the
command line.
[#8758](https://github.com/rust-lang/cargo/pull/8758)
- Added support for Unix-style glob patterns for package and target selection
flags on the command-line (such as `-p 'serde*'` or `--test '*'`).
[#8752](https://github.com/rust-lang/cargo/pull/8752)
### Changed
- Computed LTO flags are now included in the filename metadata hash so that
changes in LTO settings will independently cache build artifacts instead of
overwriting previous ones. This prevents rebuilds in some situations such as
switching between `cargo build` and `cargo test` in some circumstances.
[#8755](https://github.com/rust-lang/cargo/pull/8755)
- `cargo tree` now displays `(proc-macro)` next to proc-macro packages.
[#8765](https://github.com/rust-lang/cargo/pull/8765)
- Added a warning that the allowed characters for a feature name have been
restricted to letters, digits, `_`, `-`, and `+` to accommodate future
syntax changes. This is still a superset of the allowed syntax on crates.io,
which requires ASCII. This is intended to be changed to an error in the
future.
[#8814](https://github.com/rust-lang/cargo/pull/8814)
- `-p` without a value will now print a list of workspace package names.
[#8808](https://github.com/rust-lang/cargo/pull/8808)
- Add period to allowed feature name characters.
[#8932](https://github.com/rust-lang/cargo/pull/8932)
[#8943](https://github.com/rust-lang/cargo/pull/8943)
### Fixed
- Fixed building a library with both "dylib" and "rlib" crate types with LTO enabled.
[#8754](https://github.com/rust-lang/cargo/pull/8754)
- Fixed paths in Cargo's dep-info files.
[#8819](https://github.com/rust-lang/cargo/pull/8819)
- Fixed inconsistent source IDs in `cargo metadata` for git dependencies that
explicitly specify `branch="master"`.
[#8824](https://github.com/rust-lang/cargo/pull/8824)
- Fixed re-extracting dependencies which contained a `.cargo-ok` file.
[#8835](https://github.com/rust-lang/cargo/pull/8835)
### Nightly only
- Fixed a panic with `cargo doc -Zfeatures=itarget` in some situations.
[#8777](https://github.com/rust-lang/cargo/pull/8777)
- New implementation for namespaced features, using the syntax `dep:serde`.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#namespaced-features)
[#8799](https://github.com/rust-lang/cargo/pull/8799)
- Added support for "weak" dependency features, using the syntax
`dep_name?/feat_name`, which will enable a feature for a dependency without
also enabling the dependency.
[#8818](https://github.com/rust-lang/cargo/pull/8818)
- Fixed the new feature resolver downloading extra dependencies that weren't
strictly necessary.
[#8823](https://github.com/rust-lang/cargo/pull/8823)
## Cargo 1.48 (2020-11-19)
[51b66125...rust-1.48.0](https://github.com/rust-lang/cargo/compare/51b66125...rust-1.48.0)
### Added
- Added `term.progress` configuration option to control when and how the
progress bar is displayed.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#termprogresswhen)
[#8165](https://github.com/rust-lang/cargo/pull/8165)
- Added `--message-format plain` option to `cargo locate-project` to display
the project location without JSON to make it easier to use in a script.
[#8707](https://github.com/rust-lang/cargo/pull/8707)
- Added `--workspace` option to `cargo locate-project` to display the path to
the workspace manifest.
[#8712](https://github.com/rust-lang/cargo/pull/8712)
- A new contributor guide has been added for contributing to Cargo itself.
This is published at <https://rust-lang.github.io/cargo/contrib/>.
[#8715](https://github.com/rust-lang/cargo/pull/8715)
- Zsh `--target` completion will now complete with the built-in rustc targets.
[#8740](https://github.com/rust-lang/cargo/pull/8740)
### Changed
### Fixed
- Fixed `cargo new` creating a fossil repository to properly ignore the `target` directory.
[#8671](https://github.com/rust-lang/cargo/pull/8671)
- Don't show warnings about the workspace in the current directory when using `cargo install`
of a remote package.
[#8681](https://github.com/rust-lang/cargo/pull/8681)
- Automatically reinitialize the index when an "Object not found" error is
encountered in the git repository.
[#8735](https://github.com/rust-lang/cargo/pull/8735)
- Updated libgit2, which brings in several fixes for git repository handling.
[#8778](https://github.com/rust-lang/cargo/pull/8778)
[#8780](https://github.com/rust-lang/cargo/pull/8780)
### Nightly only
- Fixed `cargo install` so that it will ignore the `[unstable]` table in local config files.
[#8656](https://github.com/rust-lang/cargo/pull/8656)
- Fixed nondeterministic behavior of the new feature resolver.
[#8701](https://github.com/rust-lang/cargo/pull/8701)
- Fixed running `cargo test` on a proc-macro with the new feature resolver
under a specific combination of circumstances.
[#8742](https://github.com/rust-lang/cargo/pull/8742)
## Cargo 1.47 (2020-10-08)
[4f74d9b2...rust-1.47.0](https://github.com/rust-lang/cargo/compare/4f74d9b2...rust-1.47.0)
### Added
- `cargo doc` will now include the package's version in the left sidebar.
[#8509](https://github.com/rust-lang/cargo/pull/8509)
- Added the `test` field to `cargo metadata` targets.
[#8478](https://github.com/rust-lang/cargo/pull/8478)
- Cargo's man pages are now displayed via the `cargo help` command (such as
`cargo help build`).
[#8456](https://github.com/rust-lang/cargo/pull/8456)
[#8577](https://github.com/rust-lang/cargo/pull/8577)
- Added new documentation chapters on [how dependency resolution
works](https://doc.rust-lang.org/nightly/cargo/reference/resolver.html) and
[SemVer
compatibility](https://doc.rust-lang.org/nightly/cargo/reference/semver.html),
along with suggestions on how to version your project and work with
dependencies.
[#8609](https://github.com/rust-lang/cargo/pull/8609)
### Changed
- The comments added to `.gitignore` when it is modified have been tweaked to
add some spacing.
[#8476](https://github.com/rust-lang/cargo/pull/8476)
- `cargo metadata` output should now be sorted to be deterministic.
[#8489](https://github.com/rust-lang/cargo/pull/8489)
- By default, build scripts and proc-macros are now built with `opt-level=0`
and the default codegen units, even in release mode.
[#8500](https://github.com/rust-lang/cargo/pull/8500)
- `workspace.default-members` is now filtered by `workspace.exclude`.
[#8485](https://github.com/rust-lang/cargo/pull/8485)
- `workspace.members` globs now ignore non-directory paths.
[#8511](https://github.com/rust-lang/cargo/pull/8511)
- git zlib errors now trigger a retry.
[#8520](https://github.com/rust-lang/cargo/pull/8520)
- "http" class git errors now trigger a retry.
[#8553](https://github.com/rust-lang/cargo/pull/8553)
- git dependencies now override the `core.autocrlf` git configuration value to
ensure they behave consistently across platforms, particularly when
vendoring git dependencies on Windows.
[#8523](https://github.com/rust-lang/cargo/pull/8523)
- If `Cargo.lock` needs to be updated, then it will be automatically
transitioned to the new V2 format. This format removes the `[metadata]`
table, and should be easier to merge changes in source control systems. This
format was introduced in 1.38, and made the default for new projects in
1.41.
[#8554](https://github.com/rust-lang/cargo/pull/8554)
- Added preparation for support of git repositories with a non-"master"
default branch. Actual support will arrive in a future version. This
introduces some warnings:
- Warn if a git dependency does not specify a branch, and the default branch
on the repository is not "master". In the future, Cargo will fetch the
default branch. In this scenario, the branch should be explicitly
specified.
- Warn if a workspace has multiple dependencies to the same git repository,
one without a `branch` and one with `branch="master"`. Dependencies should
all use one form or the other.
[#8522](https://github.com/rust-lang/cargo/pull/8522)
- Warnings are now issued if a `required-features` entry lists a feature that
does not exist.
[#7950](https://github.com/rust-lang/cargo/pull/7950)
- Built-in aliases are now included in `cargo --list`.
[#8542](https://github.com/rust-lang/cargo/pull/8542)
- `cargo install` with a specific version that has been yanked will now
display an error message that it has been yanked, instead of "could not
find".
[#8565](https://github.com/rust-lang/cargo/pull/8565)
- `cargo publish` with a package that has the `publish` field set to a single
registry, and no `--registry` flag has been given, will now publish to that
registry instead of generating an error.
[#8571](https://github.com/rust-lang/cargo/pull/8571)
### Fixed
- Fixed issue where if a project directory was moved, and one of the
build scripts did not use the `rerun-if-changed` directive, then that
build script was being rebuilt when it shouldn't.
[#8497](https://github.com/rust-lang/cargo/pull/8497)
- Console colors should now work on Windows 7 and 8.
[#8540](https://github.com/rust-lang/cargo/pull/8540)
- The `CARGO_TARGET_{triplet}_RUNNER` environment variable will now correctly
override the config file instead of trying to merge the commands.
[#8629](https://github.com/rust-lang/cargo/pull/8629)
- Fixed LTO with doctests.
[#8657](https://github.com/rust-lang/cargo/pull/8657)
[#8658](https://github.com/rust-lang/cargo/pull/8658)
### Nightly only
- Added support for `-Z terminal-width` which tells `rustc` the width of the
terminal so that it can format diagnostics better.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#terminal-width)
[#8427](https://github.com/rust-lang/cargo/pull/8427)
- Added ability to configure `-Z` unstable flags in config files via the
`[unstable]` table.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html)
[#8393](https://github.com/rust-lang/cargo/pull/8393)
- Added `-Z build-std-features` flag to set features for the standard library.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#build-std-features)
[#8490](https://github.com/rust-lang/cargo/pull/8490)
## Cargo 1.46 (2020-08-27)
[9fcb8c1d...rust-1.46.0](https://github.com/rust-lang/cargo/compare/9fcb8c1d...rust-1.46.0)
### Added
- The `dl` key in `config.json` of a registry index now supports the
replacement markers `{prefix}` and `{lowerprefix}` to allow spreading crates
across directories similar to how the index itself is structured.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/registries.html#index-format)
[#8267](https://github.com/rust-lang/cargo/pull/8267)
- Added new environment variables that are set during compilation:
- `CARGO_CRATE_NAME`: The name of the crate being built.
- `CARGO_BIN_NAME`: The name of the executable binary (if this is a binary crate).
- `CARGO_PKG_LICENSE`: The `license` field from the manifest.
- `CARGO_PKG_LICENSE_FILE`: The `license-file` field from the manifest.
[#8270](https://github.com/rust-lang/cargo/pull/8270)
[#8325](https://github.com/rust-lang/cargo/pull/8325)
[#8387](https://github.com/rust-lang/cargo/pull/8387)
- If the value for `readme` is not specified in `Cargo.toml`, it is now
automatically inferred from the existence of a file named `README`,
`README.md`, or `README.txt`. This can be suppressed by setting
`readme = false`.
[#8277](https://github.com/rust-lang/cargo/pull/8277)
- `cargo install` now supports the `--index` flag to install directly from an index.
[#8344](https://github.com/rust-lang/cargo/pull/8344)
- Added the `metadata` table to the `workspace` definition in `Cargo.toml`.
This can be used for arbitrary data similar to the `package.metadata` table.
[#8323](https://github.com/rust-lang/cargo/pull/8323)
- Added the `--target-dir` flag to `cargo install` to set the target directory.
[#8391](https://github.com/rust-lang/cargo/pull/8391)
- Changes to environment variables used by the
[`env!`](https://doc.rust-lang.org/std/macro.env.html) or
[`option_env!`](https://doc.rust-lang.org/std/macro.option_env.html) macros
are now automatically detected to trigger a rebuild.
[#8421](https://github.com/rust-lang/cargo/pull/8421)
- The `target` directory now includes the `CACHEDIR.TAG` file which is used by
some tools to exclude the directory from backups.
[#8378](https://github.com/rust-lang/cargo/pull/8378)
- Added docs about rustup's `+toolchain` syntax.
[#8455](https://github.com/rust-lang/cargo/pull/8455)
### Changed
- A warning is now displayed if a git dependency includes a `#` fragment in
the URL. This was potentially confusing because Cargo itself displays git
URLs with this syntax, but it does not have any meaning outside of the
`Cargo.lock` file, and would not work properly.
[#8297](https://github.com/rust-lang/cargo/pull/8297)
- Various optimizations and fixes for bitcode embedding and LTO.
[#8349](https://github.com/rust-lang/cargo/pull/8349)
- Reduced the amount of data fetched for git dependencies. If Cargo knows the
branch or tag to fetch, it will now only fetch that branch or tag instead of
all branches and tags.
[#8363](https://github.com/rust-lang/cargo/pull/8363)
- Enhanced git fetch error messages.
[#8409](https://github.com/rust-lang/cargo/pull/8409)
- `.crate` files are now generated with GNU tar format instead of UStar, which
supports longer file names.
[#8453](https://github.com/rust-lang/cargo/pull/8453)
### Fixed
- Fixed a rare situation where an update to `Cargo.lock` failed once, but then
subsequent runs allowed it proceed.
[#8274](https://github.com/rust-lang/cargo/pull/8274)
- Removed assertion that Windows dylibs must have a `.dll` extension. Some
custom JSON spec targets may change the extension.
[#8310](https://github.com/rust-lang/cargo/pull/8310)
- Updated libgit2, which brings in a fix for zlib errors for some remote
git servers like googlesource.com.
[#8320](https://github.com/rust-lang/cargo/pull/8320)
- Fixed the GitHub fast-path check for up-to-date git dependencies on
non-master branches.
[#8363](https://github.com/rust-lang/cargo/pull/8363)
- Fixed issue when enabling a feature with `pkg/feature` syntax, and `pkg` is
an optional dependency, but also a dev-dependency, and the dev-dependency
appears before the optional normal dependency in the registry summary, then
the optional dependency would not get activated.
[#8395](https://github.com/rust-lang/cargo/pull/8395)
- Fixed `clean -p` deleting the build directory if there is a test named
`build`.
[#8398](https://github.com/rust-lang/cargo/pull/8398)
- Fixed indentation of multi-line Cargo error messages.
[#8409](https://github.com/rust-lang/cargo/pull/8409)
- Fixed issue where the automatic inclusion of the `--document-private-items`
flag for rustdoc would override any flags passed to the `cargo rustdoc`
command.
[#8449](https://github.com/rust-lang/cargo/pull/8449)
- Cargo will now include a version in the hash of the fingerprint directories
to support backwards-incompatible changes to the fingerprint structure.
[#8473](https://github.com/rust-lang/cargo/pull/8473)
[#8488](https://github.com/rust-lang/cargo/pull/8488)
### Nightly only
- Added `-Zrustdoc-map` feature which provides external mappings for rustdoc
(such as https://docs.rs/ links).
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#rustdoc-map)
[#8287](https://github.com/rust-lang/cargo/pull/8287)
- Fixed feature calculation when a proc-macro is declared in `Cargo.toml` with
an underscore (like `proc_macro = true`).
[#8319](https://github.com/rust-lang/cargo/pull/8319)
- Added support for setting `-Clinker` with `-Zdoctest-xcompile`.
[#8359](https://github.com/rust-lang/cargo/pull/8359)
- Fixed setting the `strip` profile field in config files.
[#8454](https://github.com/rust-lang/cargo/pull/8454)
## Cargo 1.45 (2020-07-16)
[ebda5065e...rust-1.45.0](https://github.com/rust-lang/cargo/compare/ebda5065...rust-1.45.0)
### Added
### Changed
- Changed official documentation to recommend `.cargo/config.toml` filenames
(with the `.toml` extension). `.toml` extension support was added in 1.39.
[#8121](https://github.com/rust-lang/cargo/pull/8121)
- The `registry.index` config value is no longer allowed (it has been
deprecated for 4 years).
[#7973](https://github.com/rust-lang/cargo/pull/7973)
- An error is generated if both `--index` and `--registry` are passed
(previously `--index` was silently ignored).
[#7973](https://github.com/rust-lang/cargo/pull/7973)
- The `registry.token` config value is no longer used with the `--index` flag.
This is intended to avoid potentially leaking the crates.io token to another
registry.
[#7973](https://github.com/rust-lang/cargo/pull/7973)
- Added a warning if `registry.token` is used with source replacement. It is
intended this will be an error in future versions.
[#7973](https://github.com/rust-lang/cargo/pull/7973)
- Windows GNU targets now copy `.dll.a` import library files for DLL crate
types to the output directory.
[#8141](https://github.com/rust-lang/cargo/pull/8141)
- Dylibs for all dependencies are now unconditionally copied to the output
directory. Some obscure scenarios can cause an old dylib to be referenced
between builds, and this ensures that all the latest copies are used.
[#8139](https://github.com/rust-lang/cargo/pull/8139)
- `package.exclude` can now match directory names. If a directory is
specified, the entire directory will be excluded, and Cargo will not attempt
to inspect it further. Previously Cargo would try to check every file in the
directory which could cause problems if the directory contained unreadable
files.
[#8095](https://github.com/rust-lang/cargo/pull/8095)
- When packaging with `cargo publish` or `cargo package`, Cargo can use git to
guide its decision on which files to include. Previously this git-based
logic required a `Cargo.toml` file to exist at the root of the repository.
This is no longer required, so Cargo will now use git-based guidance even if
there is not a `Cargo.toml` in the root of the repository.
[#8095](https://github.com/rust-lang/cargo/pull/8095)
- While unpacking a crate on Windows, if it fails to write a file because the
file is a reserved Windows filename (like "aux.rs"), Cargo will display an
extra message to explain why it failed.
[#8136](https://github.com/rust-lang/cargo/pull/8136)
- Failures to set mtime on files are now ignored. Some filesystems did not
support this.
[#8185](https://github.com/rust-lang/cargo/pull/8185)
- Certain classes of git errors will now recommend enabling
`net.git-fetch-with-cli`.
[#8166](https://github.com/rust-lang/cargo/pull/8166)
- When doing an LTO build, Cargo will now instruct rustc not to perform
codegen when possible. This may result in a faster build and use less disk
space. Additionally, for non-LTO builds, Cargo will instruct rustc to not
embed LLVM bitcode in libraries, which should decrease their size.
[#8192](https://github.com/rust-lang/cargo/pull/8192)
[#8226](https://github.com/rust-lang/cargo/pull/8226)
[#8254](https://github.com/rust-lang/cargo/pull/8254)
- The implementation for `cargo clean -p` has been rewritten so that it can
more accurately remove the files for a specific package.
[#8210](https://github.com/rust-lang/cargo/pull/8210)
- The way Cargo computes the outputs from a build has been rewritten to be
more complete and accurate. Newly tracked files will be displayed in JSON
messages, and may be uplifted to the output directory in some cases. Some of
the changes from this are:
- `.exp` export files on Windows MSVC dynamic libraries are now tracked.
- Proc-macros on Windows track import/export files.
- All targets (like tests, etc.) that generate separate debug files
(pdb/dSYM) are tracked.
- Added .map files for wasm32-unknown-emscripten.
- macOS dSYM directories are tracked for all dynamic libraries
(dylib/cdylib/proc-macro) and for build scripts.
There are a variety of other changes as a consequence of this:
- Binary examples on Windows MSVC with a hyphen will now show up twice in
the examples directory (`foo_bar.exe` and `foo-bar.exe`). Previously Cargo
just renamed the file instead of hard-linking it.
- Example libraries now follow the same rules for hyphen/underscore
translation as normal libs (they will now use underscores).
[#8210](https://github.com/rust-lang/cargo/pull/8210)
- Cargo attempts to scrub any secrets from the debug log for HTTP debugging.
[#8222](https://github.com/rust-lang/cargo/pull/8222)
- Context has been added to many of Cargo's filesystem operations, so that
error messages now provide more information, such as the path that caused
the problem.
[#8232](https://github.com/rust-lang/cargo/pull/8232)
- Several commands now ignore the error if stdout or stderr is closed while it
is running. For example `cargo install --list | grep -q cargo-fuzz` would
previously sometimes panic because `grep -q` may close stdout before the
command finishes. Regular builds continue to fail if stdout or stderr is
closed, matching the behavior of many other build systems.
[#8236](https://github.com/rust-lang/cargo/pull/8236)
- If `cargo install` is given an exact version, like `--version=1.2.3`, it
will now avoid updating the index if that version is already installed, and
exit quickly indicating it is already installed.
[#8022](https://github.com/rust-lang/cargo/pull/8022)
- Changes to the `[patch]` section will now attempt to automatically update
`Cargo.lock` to the new version. It should now also provide better error
messages for the rare cases where it is unable to automatically update.
[#8248](https://github.com/rust-lang/cargo/pull/8248)
### Fixed
- Fixed copying Windows `.pdb` files to the output directory when the filename
contained dashes.
[#8123](https://github.com/rust-lang/cargo/pull/8123)
- Fixed error where Cargo would fail when scanning if a package is inside a
git repository when any of its ancestor paths is a symlink.
[#8186](https://github.com/rust-lang/cargo/pull/8186)
- Fixed `cargo update` with an unused `[patch]` so that it does not get
stuck and refuse to update.
[#8243](https://github.com/rust-lang/cargo/pull/8243)
- Fixed a situation where Cargo would hang if stderr is closed, and the
compiler generated a large number of messages.
[#8247](https://github.com/rust-lang/cargo/pull/8247)
- Fixed backtraces on macOS not showing filenames or line numbers. As a
consequence of this, binary executables on apple targets do not include a
hash in the filename in Cargo's cache. This means Cargo can only track one
copy, so if you switch features or rustc versions, Cargo will need to
rebuild the executable.
[#8329](https://github.com/rust-lang/cargo/pull/8329)
[#8335](https://github.com/rust-lang/cargo/pull/8335)
- Fixed fingerprinting when using lld on Windows with a dylib. Cargo was
erroneously thinking the dylib was never fresh.
[#8290](https://github.com/rust-lang/cargo/pull/8290)
[#8335](https://github.com/rust-lang/cargo/pull/8335)
### Nightly only
- Fixed passing the full path for `--target` to `rustdoc` when using JSON spec
targets.
[#8094](https://github.com/rust-lang/cargo/pull/8094)
- `-Cembed-bitcode=no` renamed to `-Cbitcode-in-rlib=no`
[#8134](https://github.com/rust-lang/cargo/pull/8134)
- Added new `resolver` field to `Cargo.toml` to opt-in to the new feature
resolver.
[#8129](https://github.com/rust-lang/cargo/pull/8129)
- `-Zbuild-std` no longer treats std dependencies as "local". This means that
it won't use incremental compilation for those dependencies, removes them
from dep-info files, and caps lints at "allow".
[#8177](https://github.com/rust-lang/cargo/pull/8177)
- Added `-Zmultitarget` which allows multiple `--target` flags to build the
same thing for multiple targets at once.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#multitarget)
[#8167](https://github.com/rust-lang/cargo/pull/8167)
- Added `strip` option to the profile to remove symbols and debug information.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#profile-strip-option)
[#8246](https://github.com/rust-lang/cargo/pull/8246)
- Fixed panic with `cargo tree --target=all -Zfeatures=all`.
[#8269](https://github.com/rust-lang/cargo/pull/8269)
## Cargo 1.44 (2020-06-04)
[bda50510...rust-1.44.0](https://github.com/rust-lang/cargo/compare/bda50510...rust-1.44.0)
### Added
- 🔥 Added the `cargo tree` command.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-tree.html)
[#8062](https://github.com/rust-lang/cargo/pull/8062)
- Added warnings if a package has Windows-restricted filenames (like `nul`,
`con`, `aux`, `prn`, etc.).
[#7959](https://github.com/rust-lang/cargo/pull/7959)
- Added a `"build-finished"` JSON message when compilation is complete so that
tools can detect when they can stop listening for JSON messages with
commands like `cargo run` or `cargo test`.
[#8069](https://github.com/rust-lang/cargo/pull/8069)
### Changed
- Valid package names are now restricted to Unicode XID identifiers. This is
mostly the same as before, except package names cannot start with a number
or `-`.
[#7959](https://github.com/rust-lang/cargo/pull/7959)
- `cargo new` and `init` will warn or reject additional package names
(reserved Windows names, reserved Cargo directories, non-ASCII names,
conflicting std names like `core`, etc.).
[#7959](https://github.com/rust-lang/cargo/pull/7959)
- Tests are no longer hard-linked into the output directory (`target/debug/`).
This ensures tools will have access to debug symbols and execute tests in
the same way as Cargo. Tools should use JSON messages to discover the path
to the executable.
[#7965](https://github.com/rust-lang/cargo/pull/7965)
- Updating git submodules now displays an "Updating" message for each
submodule.
[#7989](https://github.com/rust-lang/cargo/pull/7989)
- File modification times are now preserved when extracting a `.crate` file.
This reverses the change made in 1.40 where the mtime was not preserved.
[#7935](https://github.com/rust-lang/cargo/pull/7935)
- Build script warnings are now displayed separately when the build script
fails.
[#8017](https://github.com/rust-lang/cargo/pull/8017)
- Removed the `git-checkout` subcommand.
[#8040](https://github.com/rust-lang/cargo/pull/8040)
- The progress bar is now enabled for all unix platforms. Previously it was
only Linux, macOS, and FreeBSD.
[#8054](https://github.com/rust-lang/cargo/pull/8054)
- Artifacts generated by pre-release versions of `rustc` now share the same
filenames. This means that changing nightly versions will not leave stale
files in the build directory.
[#8073](https://github.com/rust-lang/cargo/pull/8073)
- Invalid package names are rejected when using renamed dependencies.
[#8090](https://github.com/rust-lang/cargo/pull/8090)
- Added a certain class of HTTP2 errors as "spurious" that will get retried.
[#8102](https://github.com/rust-lang/cargo/pull/8102)
- Allow `cargo package --list` to succeed, even if there are other validation
errors (such as `Cargo.lock` generation problem, or missing dependencies).
[#8175](https://github.com/rust-lang/cargo/pull/8175)
[#8215](https://github.com/rust-lang/cargo/pull/8215)
### Fixed
- Cargo no longer buffers excessive amounts of compiler output in memory.
[#7838](https://github.com/rust-lang/cargo/pull/7838)
- Symbolic links in git repositories now work on Windows.
[#7996](https://github.com/rust-lang/cargo/pull/7996)
- Fixed an issue where `profile.dev` was not loaded from a config file with
`cargo test` when the `dev` profile was not defined in `Cargo.toml`.
[#8012](https://github.com/rust-lang/cargo/pull/8012)
- When a binary is built as an implicit dependency of an integration test,
it now checks `dep_name/feature_name` syntax in `required-features` correctly.
[#8020](https://github.com/rust-lang/cargo/pull/8020)
- Fixed an issue where Cargo would not detect that an executable (such as an
integration test) needs to be rebuilt when the previous build was
interrupted with Ctrl-C.
[#8087](https://github.com/rust-lang/cargo/pull/8087)
- Protect against some (unknown) situations where Cargo could panic when the
system monotonic clock doesn't appear to be monotonic.
[#8114](https://github.com/rust-lang/cargo/pull/8114)
- Fixed panic with `cargo clean -p` if the package has a build script.
[#8216](https://github.com/rust-lang/cargo/pull/8216)
### Nightly only
- Fixed panic with new feature resolver and required-features.
[#7962](https://github.com/rust-lang/cargo/pull/7962)
- Added `RUSTC_WORKSPACE_WRAPPER` environment variable, which provides a way
to wrap `rustc` for workspace members only, and affects the filename hash so
that artifacts produced by the wrapper are cached separately. This usage can
be seen on nightly clippy with `cargo clippy -Zunstable-options`.
[#7533](https://github.com/rust-lang/cargo/pull/7533)
- Added `--unit-graph` CLI option to display Cargo's internal dependency graph
as JSON.
[#7977](https://github.com/rust-lang/cargo/pull/7977)
- Changed `-Zbuild_dep` to `-Zhost_dep`, and added proc-macros to the feature
decoupling logic.
[#8003](https://github.com/rust-lang/cargo/pull/8003)
[#8028](https://github.com/rust-lang/cargo/pull/8028)
- Fixed so that `--crate-version` is not automatically passed when the flag
is found in `RUSTDOCFLAGS`.
[#8014](https://github.com/rust-lang/cargo/pull/8014)
- Fixed panic with `-Zfeatures=dev_dep` and `check --profile=test`.
[#8027](https://github.com/rust-lang/cargo/pull/8027)
- Fixed panic with `-Zfeatures=itarget` with certain host dependencies.
[#8048](https://github.com/rust-lang/cargo/pull/8048)
- Added support for `-Cembed-bitcode=no`, which provides a performance boost
and disk-space usage reduction for non-LTO builds.
[#8066](https://github.com/rust-lang/cargo/pull/8066)
- `-Zpackage-features` has been extended with several changes intended to make
it easier to select features on the command-line in a workspace.
[#8074](https://github.com/rust-lang/cargo/pull/8074)
## Cargo 1.43 (2020-04-23)
[9d32b7b0...rust-1.43.0](https://github.com/rust-lang/cargo/compare/9d32b7b0...rust-1.43.0)
### Added
- 🔥 Profiles may now be specified in config files (and environment variables).
[docs](https://doc.rust-lang.org/nightly/cargo/reference/config.html#profile)
[#7823](https://github.com/rust-lang/cargo/pull/7823)
- ❗ Added `CARGO_BIN_EXE_<name>` environment variable when building
integration tests. This variable contains the path to any `[[bin]]` targets
in the package. Integration tests should use the `env!` macro to determine
the path to a binary to execute.
[docs](https://doc.rust-lang.org/nightly/cargo/reference/environment-variables.html#environment-variables-cargo-sets-for-crates)
[#7697](https://github.com/rust-lang/cargo/pull/7697)
### Changed
- `cargo install --git` now honors workspaces in a git repository. This allows
workspace settings, like `[patch]`, `[replace]`, or `[profile]` to be used.
[#7768](https://github.com/rust-lang/cargo/pull/7768)
- `cargo new` will now run `rustfmt` on the new files to pick up rustfmt
settings like `tab_spaces` so that the new file matches the user's preferred
indentation settings.
[#7827](https://github.com/rust-lang/cargo/pull/7827)
- Environment variables printed with "very verbose" output (`-vv`) are now
consistently sorted.
[#7877](https://github.com/rust-lang/cargo/pull/7877)
- Debug logging for fingerprint rebuild-detection now includes more information.
[#7888](https://github.com/rust-lang/cargo/pull/7888)
[#7890](https://github.com/rust-lang/cargo/pull/7890)
[#7952](https://github.com/rust-lang/cargo/pull/7952)
- Added warning during publish if the license-file doesn't exist.
[#7905](https://github.com/rust-lang/cargo/pull/7905)
- The `license-file` file is automatically included during publish, even if it
is not explicitly listed in the `include` list or is in a location outside
of the root of the package.
[#7905](https://github.com/rust-lang/cargo/pull/7905)
- `CARGO_CFG_DEBUG_ASSERTIONS` and `CARGO_CFG_PROC_MACRO` are no longer set
when running a build script. These were inadvertently set in the past, but
had no meaning as they were always true. Additionally, `cfg(proc-macro)`
is no longer supported in a `target` expression.
[#7943](https://github.com/rust-lang/cargo/pull/7943)
[#7970](https://github.com/rust-lang/cargo/pull/7970)
### Fixed
- Global command-line flags now work with aliases (like `cargo -v b`).
[#7837](https://github.com/rust-lang/cargo/pull/7837)
- Required-features using dependency syntax (like `renamed_dep/feat_name`) now
handle renamed dependencies correctly.
[#7855](https://github.com/rust-lang/cargo/pull/7855)
- Fixed a rare situation where if a build script is run multiple times during
the same build, Cargo will now keep the results separate instead of losing
the output of the first execution.
[#7857](https://github.com/rust-lang/cargo/pull/7857)
- Fixed incorrect interpretation of environment variable
`CARGO_TARGET_*_RUNNER=true` as a boolean. Also improved related env var
error messages.
[#7891](https://github.com/rust-lang/cargo/pull/7891)
- Updated internal libgit2 library, bringing various fixes to git support.
[#7939](https://github.com/rust-lang/cargo/pull/7939)
- `cargo package` / `cargo publish` should no longer buffer the entire
contents of each file in memory.
[#7946](https://github.com/rust-lang/cargo/pull/7946)
- Ignore more invalid `Cargo.toml` files in a git dependency. Cargo currently
walks the entire repo to find the requested package. Certain invalid
manifests were already skipped, and now it should skip all of them.
[#7947](https://github.com/rust-lang/cargo/pull/7947)
### Nightly only
- Added `build.out-dir` config variable to set the output directory.
[#7810](https://github.com/rust-lang/cargo/pull/7810)

[#7872](https://github.com/rust-lang/cargo/pull/7872)
- Updated `--config` command-line flag to support taking a path to a config
file to load.
[#7901](https://github.com/rust-lang/cargo/pull/7901)
- Added new feature resolver.
[#7820](https://github.com/rust-lang/cargo/pull/7820)
- Rustdoc docs now automatically include the version of the package in the
side bar (requires `-Z crate-versions` flag).
[#7903](https://github.com/rust-lang/cargo/pull/7903)
## Cargo 1.42 (2020-03-12)
[0bf7aafe...rust-1.42.0](https://github.com/rust-lang/cargo/compare/0bf7aafe...rust-1.42.0)
### Added

- Bitbucket Pipeline badges are now supported on crates.io.
[#7663](https://github.com/rust-lang/cargo/pull/7663)
- `cargo vendor` now accepts the `--versioned-dirs` option to force it to
always include the version number in each package's directory name.
[#7631](https://github.com/rust-lang/cargo/pull/7631)
- The `proc_macro` crate is now automatically added to the extern prelude for
proc-macro packages. This means that `extern crate proc_macro;` is no longer
necessary for proc-macros.
[#7700](https://github.com/rust-lang/cargo/pull/7700)
### Changed
- Emit a warning if `debug_assertions`, `test`, `proc_macro`, or `feature=` is
used in a `cfg()` expression.
[#7660](https://github.com/rust-lang/cargo/pull/7660)
- Large update to the Cargo documentation, adding new chapters on Cargo
targets, workspaces, and features.
[#7733](https://github.com/rust-lang/cargo/pull/7733)
- Windows: `.lib` DLL import libraries are now copied next to the dll for all
Windows MSVC targets. Previously it was only supported for
`pc-windows-msvc`. This adds DLL support for `uwp-windows-msvc` targets.
[#7758](https://github.com/rust-lang/cargo/pull/7758)
- The `ar` field in the `[target]` configuration is no longer read. It has
been ignored for over 4 years.
[#7763](https://github.com/rust-lang/cargo/pull/7763)
- Bash completion file simplified and updated for latest changes.
[#7789](https://github.com/rust-lang/cargo/pull/7789)
- Credentials are only loaded when needed, instead of every Cargo command.
[#7774](https://github.com/rust-lang/cargo/pull/7774)
### Fixed
- Removed `--offline` empty index check, which was a false positive in some
cases.
[#7655](https://github.com/rust-lang/cargo/pull/7655)
- Files and directories starting with a `.` can now be included in a package
by adding it to the `include` list.
[#7680](https://github.com/rust-lang/cargo/pull/7680)
- Fixed `cargo login` removing alternative registry tokens when previous
entries existed in the credentials file.
[#7708](https://github.com/rust-lang/cargo/pull/7708)
- Fixed `cargo vendor` from panicking when used with alternative registries.
[#7718](https://github.com/rust-lang/cargo/pull/7718)
- Fixed incorrect explanation in the fingerprint debug log message.
[#7749](https://github.com/rust-lang/cargo/pull/7749)
- A `[source]` that is defined multiple times will now result in an error.
Previously it was randomly picking a source, which could cause
non-deterministic behavior.
[#7751](https://github.com/rust-lang/cargo/pull/7751)
- `dep_kinds` in `cargo metadata` are now de-duplicated.
[#7756](https://github.com/rust-lang/cargo/pull/7756)
- Fixed packaging where `Cargo.lock` was listed in `.gitignore` in a
subdirectory inside a git repository. Previously it was assuming
`Cargo.lock` was at the root of the repo.
[#7779](https://github.com/rust-lang/cargo/pull/7779)
- Partial file transfer errors will now cause an automatic retry.
[#7788](https://github.com/rust-lang/cargo/pull/7788)
- Linux: Fixed panic if CPU iowait stat decreases.
[#7803](https://github.com/rust-lang/cargo/pull/7803)
- Fixed using the wrong sysroot for detecting host compiler settings when
`--sysroot` is passed in via `RUSTFLAGS`.
[#7798](https://github.com/rust-lang/cargo/pull/7798)
### Nightly only
- `build-std` now uses `--extern` instead of `--sysroot` to find sysroot
packages.
[#7699](https://github.com/rust-lang/cargo/pull/7699)
- Added `--config` command-line option to set config settings.
[#7649](https://github.com/rust-lang/cargo/pull/7649)
- Added `include` config setting which allows including another config file.
[#7649](https://github.com/rust-lang/cargo/pull/7649)
- Profiles in config files now support any named profile. Previously it was
limited to dev/release.
[#7750](https://github.com/rust-lang/cargo/pull/7750)
## Cargo 1.41 (2020-01-30)
[5da4b4d4...rust-1.41.0](https://github.com/rust-lang/cargo/compare/5da4b4d4...rust-1.41.0)
### Added
- 🔥 Cargo now uses a new `Cargo.lock` file format. This new format should
support easier merges in source control systems. Projects using the old
format will continue to use the old format, only new `Cargo.lock` files will
use the new format.
[#7579](https://github.com/rust-lang/cargo/pull/7579)
- 🔥 `cargo install` will now upgrade already installed packages instead of
failing.
[#7560](https://github.com/rust-lang/cargo/pull/7560)
- 🔥 Profile overrides have been added. This allows overriding profiles for
individual dependencies or build scripts. See [the
documentation](https://doc.rust-lang.org/nightly/cargo/reference/profiles.html#overrides)
for more.
[#7591](https://github.com/rust-lang/cargo/pull/7591)
- Added new documentation for build scripts.
[#7565](https://github.com/rust-lang/cargo/pull/7565)
- Added documentation for Cargo's JSON output.
[#7595](https://github.com/rust-lang/cargo/pull/7595)
- Significant expansion of config and environment variable documentation.
[#7650](https://github.com/rust-lang/cargo/pull/7650)
- Add back support for `BROWSER` environment variable for `cargo doc --open`.
[#7576](https://github.com/rust-lang/cargo/pull/7576)
- Added `kind` and `platform` for dependencies in `cargo metadata`.
[#7132](https://github.com/rust-lang/cargo/pull/7132)
- The `OUT_DIR` value is now included in the `build-script-executed` JSON message.
[#7622](https://github.com/rust-lang/cargo/pull/7622)
### Changed
- `cargo doc` will now document private items in binaries by default.
[#7593](https://github.com/rust-lang/cargo/pull/7593)
- Subcommand typo suggestions now include aliases.
[#7486](https://github.com/rust-lang/cargo/pull/7486)
- Tweak how the "already existing..." comment is added to `.gitignore`.
[#7570](https://github.com/rust-lang/cargo/pull/7570)
- Ignore `cargo login` text from copy/paste in token.
[#7588](https://github.com/rust-lang/cargo/pull/7588)
- Windows: Ignore errors for locking files when not supported by the filesystem.
[#7602](https://github.com/rust-lang/cargo/pull/7602)
- Remove `**/*.rs.bk` from `.gitignore`.
[#7647](https://github.com/rust-lang/cargo/pull/7647)
### Fixed
- Fix unused warnings for some keys in the `build` config section.
[#7575](https://github.com/rust-lang/cargo/pull/7575)
- Linux: Don't panic when parsing `/proc/stat`.
[#7580](https://github.com/rust-lang/cargo/pull/7580)
- Don't show canonical path in `cargo vendor`.
[#7629](https://github.com/rust-lang/cargo/pull/7629)
### Nightly only
## Cargo 1.40 (2019-12-19)
[1c6ec66d...5da4b4d4](https://github.com/rust-lang/cargo/compare/1c6ec66d...5da4b4d4)
### Added
- Added `http.ssl-version` config option to control the version of TLS,
along with min/max versions.
[#7308](https://github.com/rust-lang/cargo/pull/7308)
- 🔥 Compiler warnings are now cached on disk. If a build generates warnings,
re-running the build will now re-display the warnings.
[#7450](https://github.com/rust-lang/cargo/pull/7450)
- Added `--filter-platform` option to `cargo metadata` to narrow the nodes
shown in the resolver graph to only packages included for the given target
triple.
[#7376](https://github.com/rust-lang/cargo/pull/7376)
### Changed
- Cargo's "platform" `cfg` parsing has been extracted into a separate crate
named `cargo-platform`.
[#7375](https://github.com/rust-lang/cargo/pull/7375)
- Dependencies extracted into Cargo's cache no longer preserve mtimes to
reduce syscall overhead.
[#7465](https://github.com/rust-lang/cargo/pull/7465)
- Windows: EXE files no longer include a metadata hash in the filename.
This helps with debuggers correlating the filename with the PDB file.
[#7400](https://github.com/rust-lang/cargo/pull/7400)
- Wasm32: `.wasm` files are no longer treated as an "executable", allowing
`cargo test` and `cargo run` to work properly with the generated `.js` file.
[#7476](https://github.com/rust-lang/cargo/pull/7476)
- crates.io now supports SPDX 3.6 licenses.
[#7481](https://github.com/rust-lang/cargo/pull/7481)
- Improved cyclic dependency error message.
[#7470](https://github.com/rust-lang/cargo/pull/7470)
- Bare `cargo clean` no longer locks the package cache.
[#7502](https://github.com/rust-lang/cargo/pull/7502)
- `cargo publish` now allows dev-dependencies without a version key to be
published. A git or path-only dev-dependency will be removed from the
package manifest before uploading.
[#7333](https://github.com/rust-lang/cargo/pull/7333)
- `--features` and `--no-default-features` in the root of a virtual workspace
will now generate an error instead of being ignored.
[#7507](https://github.com/rust-lang/cargo/pull/7507)
- Generated files (like `Cargo.toml` and `Cargo.lock`) in a package archive
now have their timestamp set to the current time instead of the epoch.
[#7523](https://github.com/rust-lang/cargo/pull/7523)
- The `-Z` flag parser is now more strict, rejecting more invalid syntax.
[#7531](https://github.com/rust-lang/cargo/pull/7531)
### Fixed
- Fixed an issue where if a package had an `include` field, and `Cargo.lock`
in `.gitignore`, and a binary or example target, and the `Cargo.lock` exists
in the current project, it would fail to publish complaining the
`Cargo.lock` was dirty.
[#7448](https://github.com/rust-lang/cargo/pull/7448)
- Fixed a panic in a particular combination of `[patch]` entries.
[#7452](https://github.com/rust-lang/cargo/pull/7452)
- Windows: Better error message when `cargo test` or `rustc` crashes in an
abnormal way, such as a signal or seg fault.
[#7535](https://github.com/rust-lang/cargo/pull/7535)
### Nightly only
- The `mtime-on-use` feature may now be enabled via the
`unstable.mtime_on_use` config option.
[#7411](https://github.com/rust-lang/cargo/pull/7411)
- Added support for named profiles.
[#6989](https://github.com/rust-lang/cargo/pull/6989)
- Added `-Zpanic-abort-tests` to allow building and running tests with the
"abort" panic strategy.
[#7460](https://github.com/rust-lang/cargo/pull/7460)
- Changed `build-std` to use `--sysroot`.
[#7421](https://github.com/rust-lang/cargo/pull/7421)
- Various fixes and enhancements to `-Ztimings`.
[#7395](https://github.com/rust-lang/cargo/pull/7395)
[#7398](https://github.com/rust-lang/cargo/pull/7398)
[#7397](https://github.com/rust-lang/cargo/pull/7397)
[#7403](https://github.com/rust-lang/cargo/pull/7403)
[#7428](https://github.com/rust-lang/cargo/pull/7428)
[#7429](https://github.com/rust-lang/cargo/pull/7429)
- Profile overrides have renamed the syntax to be
`[profile.dev.package.NAME]`.
[#7504](https://github.com/rust-lang/cargo/pull/7504)
- Fixed warnings for unused profile overrides in a workspace.
[#7536](https://github.com/rust-lang/cargo/pull/7536)
## Cargo 1.39 (2019-11-07)
[e853aa97...1c6ec66d](https://github.com/rust-lang/cargo/compare/e853aa97...1c6ec66d)
### Added
- Config files may now use the `.toml` filename extension.
[#7295](https://github.com/rust-lang/cargo/pull/7295)
- The `--workspace` flag has been added as an alias for `--all` to help avoid
confusion about the meaning of "all".
[#7241](https://github.com/rust-lang/cargo/pull/7241)
- The `publish` field has been added to `cargo metadata`.
[#7354](https://github.com/rust-lang/cargo/pull/7354)
### Changed
- Display more information if parsing the output from `rustc` fails.
[#7236](https://github.com/rust-lang/cargo/pull/7236)
- TOML errors now show the column number.
[#7248](https://github.com/rust-lang/cargo/pull/7248)
- `cargo vendor` no longer deletes files in the `vendor` directory that starts
with a `.`.
[#7242](https://github.com/rust-lang/cargo/pull/7242)
- `cargo fetch` will now show manifest warnings.
[#7243](https://github.com/rust-lang/cargo/pull/7243)
- `cargo publish` will now check git submodules if they contain any
uncommitted changes.
[#7245](https://github.com/rust-lang/cargo/pull/7245)
- In a build script, `cargo:rustc-flags` now allows `-l` and `-L` flags
without spaces.
[#7257](https://github.com/rust-lang/cargo/pull/7257)
- When `cargo install` replaces an older version of a package it will now
delete any installed binaries that are no longer present in the newly
installed version.
[#7246](https://github.com/rust-lang/cargo/pull/7246)
- A git dependency may now also specify a `version` key when published. The
`git` value will be stripped from the uploaded crate, matching the behavior
of `path` dependencies.
[#7237](https://github.com/rust-lang/cargo/pull/7237)
- The behavior of workspace default-members has changed. The default-members
now only applies when running Cargo in the root of the workspace. Previously
it would always apply regardless of which directory Cargo is running in.
[#7270](https://github.com/rust-lang/cargo/pull/7270)
- libgit2 updated pulling in all upstream changes.
[#7275](https://github.com/rust-lang/cargo/pull/7275)
- Bump `home` dependency for locating home directories.
[#7277](https://github.com/rust-lang/cargo/pull/7277)
- zsh completions have been updated.
[#7296](https://github.com/rust-lang/cargo/pull/7296)
- SSL connect errors are now retried.
[#7318](https://github.com/rust-lang/cargo/pull/7318)
- The jobserver has been changed to acquire N tokens (instead of N-1), and
then immediately acquires the extra token. This was changed to accommodate
the `cc` crate on Windows to allow it to release its implicit token.
[#7344](https://github.com/rust-lang/cargo/pull/7344)
- The scheduling algorithm for choosing which crate to build next has been
changed. It now chooses the crate with the greatest number of transitive
crates waiting on it. Previously it used a maximum topological depth.
[#7390](https://github.com/rust-lang/cargo/pull/7390)
- RUSTFLAGS are no longer incorporated in the metadata and filename hash,
reversing the change from 1.33 that added it. This means that any change to
RUSTFLAGS will cause a recompile, and will not affect symbol munging.
[#7459](https://github.com/rust-lang/cargo/pull/7459)
### Fixed
- Git dependencies with submodules with shorthand SSH URLs (like
`git@github.com/user/repo.git`) should now work.
[#7238](https://github.com/rust-lang/cargo/pull/7238)
- Handle broken symlinks when creating `.dSYM` symlinks on macOS.
[#7268](https://github.com/rust-lang/cargo/pull/7268)
- Fixed issues with multiple versions of the same crate in a `[patch]` table.
[#7303](https://github.com/rust-lang/cargo/pull/7303)
- Fixed issue with custom target `.json` files where a substring of the name
matches an unsupported crate type (like "bin").
[#7363](https://github.com/rust-lang/cargo/issues/7363)
- Fixed issues with generating documentation for proc-macro crate types.
[#7159](https://github.com/rust-lang/cargo/pull/7159)
- Fixed hang if Cargo panics within a build thread.
[#7366](https://github.com/rust-lang/cargo/pull/7366)
- Fixed rebuild detection if a `build.rs` script issues different `rerun-if`
directives between builds. Cargo was erroneously causing a rebuild after the
change.
[#7373](https://github.com/rust-lang/cargo/pull/7373)
- Properly handle canonical URLs for `[patch]` table entries, preventing
the patch from working after the first time it is used.
[#7368](https://github.com/rust-lang/cargo/pull/7368)
- Fixed an issue where integration tests were waiting for the package binary
to finish building before starting their own build. They now may build
concurrently.
[#7394](https://github.com/rust-lang/cargo/pull/7394)
- Fixed accidental change in the previous release on how `--features a b` flag
is interpreted, restoring the original behavior where this is interpreted as
`--features a` along with the argument `b` passed to the command. To pass
multiple features, use quotes around the features to pass multiple features
like `--features "a b"`, or use commas, or use multiple `--features` flags.
[#7419](https://github.com/rust-lang/cargo/pull/7419)
### Nightly only
- Basic support for building the standard library directly from Cargo has been
added.
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#build-std))
[#7216](https://github.com/rust-lang/cargo/pull/7216)
- Added `-Ztimings` feature to generate an HTML report on the time spent on
individual compilation steps. This also may output completion steps on the
console and JSON data.
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#timings))
[#7311](https://github.com/rust-lang/cargo/pull/7311)
- Added ability to cross-compile doctests.
([docs](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#doctest-xcompile))
[#6892](https://github.com/rust-lang/cargo/pull/6892)
## Cargo 1.38 (2019-09-26)
[4c1fa54d...23ef9a4e](https://github.com/rust-lang/cargo/compare/4c1fa54d...23ef9a4e)
### Added
- 🔥 Cargo build pipelining has been enabled by default to leverage more idle CPU
parallelism during builds.
[#7143](https://github.com/rust-lang/cargo/pull/7143)
- The `--message-format` option to Cargo can now be specified multiple times and
accepts a comma-separated list of values. In addition to the previous values
it also now accepts `json-diagnostic-short` and
`json-diagnostic-rendered-ansi` which configures the output coming from rustc
in `json` message mode.
[#7214](https://github.com/rust-lang/cargo/pull/7214)
- Cirrus CI badges are now supported on crates.io.
[#7119](https://github.com/rust-lang/cargo/pull/7119)
- A new format for `Cargo.lock` has been introduced. This new format is
intended to avoid source-control merge conflicts more often, and to
generally make it safer to merge changes. This new format is *not* enabled
at this time, though Cargo will use it if it sees it. At some point in the
future, it is intended that this will become the default.
[#7070](https://github.com/rust-lang/cargo/pull/7070)
- Progress bar support added for FreeBSD.
[#7222](https://github.com/rust-lang/cargo/pull/7222)
### Changed
- The `-q` flag will no longer suppress the root error message for an error
from Cargo itself.
[#7116](https://github.com/rust-lang/cargo/pull/7116)
- The Cargo Book is now published with mdbook 0.3 providing a number of
formatting fixes and improvements.
[#7140](https://github.com/rust-lang/cargo/pull/7140)
- The `--features` command-line flag can now be specified multiple times.
The list of features from all the flags are joined together.
[#7084](https://github.com/rust-lang/cargo/pull/7084)
- Package include/exclude glob-vs-gitignore warnings have been removed.
Packages may now use gitignore-style matching without producing any
warnings.
[#7170](https://github.com/rust-lang/cargo/pull/7170)
- Cargo now shows the command and output when parsing `rustc` output fails
when querying `rustc` for information like `cfg` values.
[#7185](https://github.com/rust-lang/cargo/pull/7185)
- `cargo package`/`cargo publish` now allows a symbolic link to a git
submodule to include that submodule.
[#6817](https://github.com/rust-lang/cargo/pull/6817)
- Improved the error message when a version requirement does not
match any versions, but there are pre-release versions available.
[#7191](https://github.com/rust-lang/cargo/pull/7191)
### Fixed
- Fixed using the wrong directory when updating git repositories when using
the `git-fetch-with-cli` config option, and the `GIT_DIR` environment
variable is set. This may happen when running cargo from git callbacks.
[#7082](https://github.com/rust-lang/cargo/pull/7082)
- Fixed dep-info files being overwritten for targets that have separate debug
outputs. For example, binaries on `-apple-` targets with `.dSYM` directories
would overwrite the `.d` file.
[#7057](https://github.com/rust-lang/cargo/pull/7057)
- Fix `[patch]` table not preserving "one major version per source" rule.
[#7118](https://github.com/rust-lang/cargo/pull/7118)
- Ignore `--remap-path-prefix` flags for the metadata hash in the `cargo
rustc` command. This was causing the remap settings to inadvertently affect
symbol names.
[#7134](https://github.com/rust-lang/cargo/pull/7134)
- Fixed cycle detection in `[patch]` dependencies.
[#7174](https://github.com/rust-lang/cargo/pull/7174)
- Fixed `cargo new` leaving behind a symlink on Windows when `core.symlinks`
git config is true. Also adds a number of fixes and updates from upstream
libgit2.
[#7176](https://github.com/rust-lang/cargo/pull/7176)
- macOS: Fixed setting the flag to mark the `target` directory to be excluded
from backups.
[#7192](https://github.com/rust-lang/cargo/pull/7192)
- Fixed `cargo fix` panicking under some situations involving multi-byte
characters.
[#7221](https://github.com/rust-lang/cargo/pull/7221)
### Nightly only
- Added `cargo fix --clippy` which will apply machine-applicable fixes from
Clippy.
[#7069](https://github.com/rust-lang/cargo/pull/7069)
- Added `-Z binary-dep-depinfo` flag to add change tracking for binary
dependencies like the standard library.
[#7137](https://github.com/rust-lang/cargo/pull/7137)
[#7219](https://github.com/rust-lang/cargo/pull/7219)
- `cargo clippy-preview` will always run, even if no changes have been made.
[#7157](https://github.com/rust-lang/cargo/pull/7157)
- Fixed exponential blowup when using `CARGO_BUILD_PIPELINING`.
[#7062](https://github.com/rust-lang/cargo/pull/7062)
- Fixed passing args to clippy in `cargo clippy-preview`.
[#7162](https://github.com/rust-lang/cargo/pull/7162)
## Cargo 1.37 (2019-08-15)
[c4fcfb72...9edd0891](https://github.com/rust-lang/cargo/compare/c4fcfb72...9edd0891)
### Added
- Added `doctest` field to `cargo metadata` to determine if a target's
documentation is tested.
[#6953](https://github.com/rust-lang/cargo/pull/6953)
[#6965](https://github.com/rust-lang/cargo/pull/6965)
- 🔥 The [`cargo
vendor`](https://doc.rust-lang.org/nightly/cargo/commands/cargo-vendor.html)
command is now built-in to Cargo. This command may be used to create a local
copy of the sources of all dependencies.
[#6869](https://github.com/rust-lang/cargo/pull/6869)
- 🔥 The "publish lockfile" feature is now stable. This feature will
automatically include the `Cargo.lock` file when a package is published if
it contains a binary executable target. By default, Cargo will ignore
`Cargo.lock` when installing a package. To force Cargo to use the
`Cargo.lock` file included in the published package, use `cargo install
--locked`. This may be useful to ensure that `cargo install` consistently
reproduces the same result. It may also be useful when a semver-incompatible
change is accidentally published to a dependency, providing a way to fall
back to a version that is known to work.
[#7026](https://github.com/rust-lang/cargo/pull/7026)
- 🔥 The `default-run` feature has been stabilized. This feature allows you to
specify which binary executable to run by default with `cargo run` when a
package includes multiple binaries. Set the `default-run` key in the
`[package]` table in `Cargo.toml` to the name of the binary to use by
default.
[#7056](https://github.com/rust-lang/cargo/pull/7056)
### Changed
- `cargo package` now verifies that build scripts do not create empty
directories.
[#6973](https://github.com/rust-lang/cargo/pull/6973)
- A warning is now issued if `cargo doc` generates duplicate outputs, which
causes files to be randomly stomped on. This may happen for a variety of
reasons (renamed dependencies, multiple versions of the same package,
packages with renamed libraries, etc.). This is a known bug, which needs
more work to handle correctly.
[#6998](https://github.com/rust-lang/cargo/pull/6998)
- Enabling a dependency's feature with `--features foo/bar` will no longer
compile the current crate with the `foo` feature if `foo` is not an optional
dependency.
[#7010](https://github.com/rust-lang/cargo/pull/7010)
- If `--remap-path-prefix` is passed via RUSTFLAGS, it will no longer affect
the filename metadata hash.
[#6966](https://github.com/rust-lang/cargo/pull/6966)
- libgit2 has been updated to 0.28.2, which Cargo uses to access git
repositories. This brings in hundreds of changes and fixes since it was last
updated in November.
[#7018](https://github.com/rust-lang/cargo/pull/7018)
- Cargo now supports absolute paths in the dep-info files generated by rustc.
This is laying the groundwork for [tracking
binaries](https://github.com/rust-lang/rust/pull/61727), such as libstd, for
rebuild detection. (Note: this contains a known bug.)
[#7030](https://github.com/rust-lang/cargo/pull/7030)
### Fixed
- Fixed how zsh completions fetch the list of commands.
[#6956](https://github.com/rust-lang/cargo/pull/6956)
- "+ debuginfo" is no longer printed in the build summary when `debug` is set
to 0.
[#6971](https://github.com/rust-lang/cargo/pull/6971)
- Fixed `cargo doc` with an example configured with `doc = true` to document
correctly.
[#7023](https://github.com/rust-lang/cargo/pull/7023)
- Don't fail if a read-only lock cannot be acquired in CARGO_HOME. This helps
when CARGO_HOME doesn't exist, but `--locked` is used which means CARGO_HOME
is not needed.
[#7149](https://github.com/rust-lang/cargo/pull/7149)
- Reverted a change in 1.35 which released jobserver tokens when Cargo blocked
on a lock file. It caused a deadlock in some situations.
[#7204](https://github.com/rust-lang/cargo/pull/7204)
### Nightly only
- Added [compiler message
caching](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#cache-messages).
The `-Z cache-messages` flag makes cargo cache the compiler output so that
future runs can redisplay previous warnings.
[#6933](https://github.com/rust-lang/cargo/pull/6933)
- `-Z mtime-on-use` no longer touches intermediate artifacts.
[#7050](https://github.com/rust-lang/cargo/pull/7050)
## Cargo 1.36 (2019-07-04)
[6f3e9c36...c4fcfb72](https://github.com/rust-lang/cargo/compare/6f3e9c36...c4fcfb72)
### Added
- Added more detailed documentation on target auto-discovery.
[#6898](https://github.com/rust-lang/cargo/pull/6898)
- 🔥 Stabilize the `--offline` flag which allows using cargo without a network
connection.
[#6934](https://github.com/rust-lang/cargo/pull/6934)
[#6871](https://github.com/rust-lang/cargo/pull/6871)
### Changed
- `publish = ["crates-io"]` may be added to the manifest to restrict
publishing to crates.io only.
[#6838](https://github.com/rust-lang/cargo/pull/6838)
- macOS: Only include the default paths if `DYLD_FALLBACK_LIBRARY_PATH` is not
set. Also, remove `/lib` from the default set.
[#6856](https://github.com/rust-lang/cargo/pull/6856)
- `cargo publish` will now exit early if the login token is not available.
[#6854](https://github.com/rust-lang/cargo/pull/6854)
- HTTP/2 stream errors are now considered "spurious" and will cause a retry.
[#6861](https://github.com/rust-lang/cargo/pull/6861)
- Setting a feature on a dependency where that feature points to a *required*
dependency is now an error. Previously it was a warning.
[#6860](https://github.com/rust-lang/cargo/pull/6860)
- The `registry.index` config value now supports relative `file:` URLs.
[#6873](https://github.com/rust-lang/cargo/pull/6873)
- macOS: The `.dSYM` directory is now symbolically linked next to example
binaries without the metadata hash so that debuggers can find it.
[#6891](https://github.com/rust-lang/cargo/pull/6891)
- The default `Cargo.toml` template for now projects now includes a comment
providing a link to the documentation.
[#6881](https://github.com/rust-lang/cargo/pull/6881)
- Some improvements to the wording of the crate download summary.
[#6916](https://github.com/rust-lang/cargo/pull/6916)
[#6920](https://github.com/rust-lang/cargo/pull/6920)
- ✨ Changed `RUST_LOG` environment variable to `CARGO_LOG` so that user code
that uses the `log` crate will not display cargo's debug output.
[#6918](https://github.com/rust-lang/cargo/pull/6918)
- `Cargo.toml` is now always included when packaging, even if it is not listed
in `package.include`.
[#6925](https://github.com/rust-lang/cargo/pull/6925)
- Package include/exclude values now use gitignore patterns instead of glob
patterns. [#6924](https://github.com/rust-lang/cargo/pull/6924)
- Provide a better error message when crates.io times out. Also improve error
messages with other HTTP response codes.
[#6936](https://github.com/rust-lang/cargo/pull/6936)
### Performance
- Resolver performance improvements for some cases.
[#6853](https://github.com/rust-lang/cargo/pull/6853)
- Optimized how cargo reads the index JSON files by caching the results.
[#6880](https://github.com/rust-lang/cargo/pull/6880)
[#6912](https://github.com/rust-lang/cargo/pull/6912)
[#6940](https://github.com/rust-lang/cargo/pull/6940)
- Various performance improvements.
[#6867](https://github.com/rust-lang/cargo/pull/6867)
### Fixed
- More carefully track the on-disk fingerprint information for dependencies.
This can help in some rare cases where the build is interrupted and
restarted. [#6832](https://github.com/rust-lang/cargo/pull/6832)
- `cargo run` now correctly passes non-UTF8 arguments to the child process.
[#6849](https://github.com/rust-lang/cargo/pull/6849)
- Fixed bash completion to run on bash 3.2, the stock version in macOS.
[#6905](https://github.com/rust-lang/cargo/pull/6905)
- Various fixes and improvements to zsh completion.
[#6926](https://github.com/rust-lang/cargo/pull/6926)
[#6929](https://github.com/rust-lang/cargo/pull/6929)
- Fix `cargo update` ignoring `-p` arguments if the `Cargo.lock` file was
missing.
[#6904](https://github.com/rust-lang/cargo/pull/6904)
### Nightly only
- Added [`-Z install-upgrade`
feature](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#install-upgrade)
to track details about installed crates and to update them if they are
out-of-date. [#6798](https://github.com/rust-lang/cargo/pull/6798)
- Added the [`public-dependency`
feature](https://doc.rust-lang.org/nightly/cargo/reference/unstable.html#public-dependency)
which allows tracking public versus private dependencies.
[#6772](https://github.com/rust-lang/cargo/pull/6772)
- Added build pipelining via the `build.pipelining` config
option (`CARGO_BUILD_PIPELINING` env var).
[#6883](https://github.com/rust-lang/cargo/pull/6883)
- The `publish-lockfile` feature has had some significant changes. The default
is now `true`, the `Cargo.lock` will always be published for binary crates.
The `Cargo.lock` is now regenerated during publishing. `cargo install` now
ignores the `Cargo.lock` file by default, and requires `--locked` to use the
lock file. Warnings have been added if yanked dependencies are detected.
[#6840](https://github.com/rust-lang/cargo/pull/6840)
## Cargo 1.35 (2019-05-23)
[6789d8a0...6f3e9c36](https://github.com/rust-lang/cargo/compare/6789d8a0...6f3e9c36)
### Added
- Added the `rustc-cdylib-link-arg` key for build scripts to specify linker
arguments for cdylib crates.
[#6298](https://github.com/rust-lang/cargo/pull/6298)
### Changed
- When passing a test filter, such as `cargo test foo`, don't build examples
(unless they set `test = true`).
[#6683](https://github.com/rust-lang/cargo/pull/6683)
- Forward the `--quiet` flag from `cargo test` to the libtest harness so that
tests are actually quiet.
[#6358](https://github.com/rust-lang/cargo/pull/6358)
- The verification step in `cargo package` that checks if any files are
modified is now stricter. It uses a hash of the contents instead of checking
filesystem mtimes. It also checks *all* files in the package.
[#6740](https://github.com/rust-lang/cargo/pull/6740)
- Jobserver tokens are now released whenever Cargo blocks on a file lock.
[#6748](https://github.com/rust-lang/cargo/pull/6748)
- Issue a warning for a previous bug in the TOML parser that allowed multiple
table headers with the same name.
[#6761](https://github.com/rust-lang/cargo/pull/6761)
- Removed the `CARGO_PKG_*` environment variables from the metadata hash and
added them to the fingerprint instead. This means that when these values
change, stale artifacts are not left behind. Also added the "repository"
value to the fingerprint.
[#6785](https://github.com/rust-lang/cargo/pull/6785)
- `cargo metadata` no longer shows a `null` field for a dependency without a
library in `resolve.nodes.deps`. The dependency is no longer shown.
[#6534](https://github.com/rust-lang/cargo/pull/6534)
- `cargo new` will no longer include an email address in the `authors` field
if it is set to the empty string.
[#6802](https://github.com/rust-lang/cargo/pull/6802)
- `cargo doc --open` now works when documenting multiple packages.
[#6803](https://github.com/rust-lang/cargo/pull/6803)
- `cargo install --path P` now loads the `.cargo/config` file from the
directory P. [#6805](https://github.com/rust-lang/cargo/pull/6805)
- Using semver metadata in a version requirement (such as `1.0.0+1234`) now
issues a warning that it is ignored.
[#6806](https://github.com/rust-lang/cargo/pull/6806)
- `cargo install` now rejects certain combinations of flags where some flags
would have been ignored.
[#6801](https://github.com/rust-lang/cargo/pull/6801)
- Resolver performance improvements for some cases.
[#6776](https://github.com/rust-lang/cargo/pull/6776)
### Fixed
- Fixed running separate commands (such as `cargo build` then `cargo test`)
where the second command could use stale results from a build script.
[#6720](https://github.com/rust-lang/cargo/pull/6720)
- Fixed `cargo fix` not working properly if a `.gitignore` file that matched
the root package directory.
[#6767](https://github.com/rust-lang/cargo/pull/6767)
- Fixed accidentally compiling a lib multiple times if `panic=unwind` was set
in a profile. [#6781](https://github.com/rust-lang/cargo/pull/6781)
- Paths to JSON files in `build.target` config value are now canonicalized to
fix building dependencies.
[#6778](https://github.com/rust-lang/cargo/pull/6778)
- Fixed re-running a build script if its compilation was interrupted (such as
if it is killed). [#6782](https://github.com/rust-lang/cargo/pull/6782)
- Fixed `cargo new` initializing a fossil repo.
[#6792](https://github.com/rust-lang/cargo/pull/6792)
- Fixed supporting updating a git repo that has a force push when using the
`git-fetch-with-cli` feature. `git-fetch-with-cli` also shows more error
information now when it fails.
[#6800](https://github.com/rust-lang/cargo/pull/6800)
- `--example` binaries built for the WASM target are fixed to no longer
include a metadata hash in the filename, and are correctly emitted in the
`compiler-artifact` JSON message.
[#6812](https://github.com/rust-lang/cargo/pull/6812)
### Nightly only
- `cargo clippy-preview` is now a built-in cargo command.
[#6759](https://github.com/rust-lang/cargo/pull/6759)
- The `build-override` profile setting now includes proc-macros and their
dependencies.
[#6811](https://github.com/rust-lang/cargo/pull/6811)
- Optional and target dependencies now work better with `-Z offline`.
[#6814](https://github.com/rust-lang/cargo/pull/6814)
## Cargo 1.34 (2019-04-11)
[f099fe94...6789d8a0](https://github.com/rust-lang/cargo/compare/f099fe94...6789d8a0)
### Added
- 🔥 Stabilized support for [alternate
registries](https://doc.rust-lang.org/1.34.0/cargo/reference/registries.html).
[#6654](https://github.com/rust-lang/cargo/pull/6654)
- Added documentation on using builds.sr.ht Continuous Integration with Cargo.
[#6565](https://github.com/rust-lang/cargo/pull/6565)
- `Cargo.lock` now includes a comment at the top that it is `@generated`.
[#6548](https://github.com/rust-lang/cargo/pull/6548)
- Azure DevOps badges are now supported.
[#6264](https://github.com/rust-lang/cargo/pull/6264)
- Added a warning if `--exclude` flag specifies an unknown package.
[#6679](https://github.com/rust-lang/cargo/pull/6679)
### Changed
- `cargo test --doc --no-run` doesn't do anything, so it now displays an error
to that effect. [#6628](https://github.com/rust-lang/cargo/pull/6628)
- Various updates to bash completion: add missing options and commands,
support libtest completions, use rustup for `--target` completion, fallback
to filename completion, fix editing the command line.
[#6644](https://github.com/rust-lang/cargo/pull/6644)
- Publishing a crate with a `[patch]` section no longer generates an error.
The `[patch]` section is removed from the manifest before publishing.
[#6535](https://github.com/rust-lang/cargo/pull/6535)
- `build.incremental = true` config value is now treated the same as
`CARGO_INCREMENTAL=1`, previously it was ignored.
[#6688](https://github.com/rust-lang/cargo/pull/6688)
- Errors from a registry are now always displayed regardless of the HTTP
response code. [#6771](https://github.com/rust-lang/cargo/pull/6771)
### Fixed
- Fixed bash completion for `cargo run --example`.
[#6578](https://github.com/rust-lang/cargo/pull/6578)
- Fixed a race condition when using a *local* registry and running multiple
cargo commands at the same time that build the same crate.
[#6591](https://github.com/rust-lang/cargo/pull/6591)
- Fixed some flickering and excessive updates of the progress bar.
[#6615](https://github.com/rust-lang/cargo/pull/6615)
- Fixed a hang when using a git credential helper that returns incorrect
credentials. [#6681](https://github.com/rust-lang/cargo/pull/6681)
- Fixed resolving yanked crates with a local registry.
[#6750](https://github.com/rust-lang/cargo/pull/6750)
### Nightly only
- Added `-Z mtime-on-use` flag to cause the mtime to be updated on the
filesystem when a crate is used. This is intended to be able to track stale
artifacts in the future for cleaning up unused files.
[#6477](https://github.com/rust-lang/cargo/pull/6477)
[#6573](https://github.com/rust-lang/cargo/pull/6573)
- Added experimental `-Z dual-proc-macros` to build proc macros for both the
host and the target.
[#6547](https://github.com/rust-lang/cargo/pull/6547)
## Cargo 1.33 (2019-02-28)
[8610973a...f099fe94](https://github.com/rust-lang/cargo/compare/8610973a...f099fe94)
### Added
- `compiler-artifact` JSON messages now include an `"executable"` key which
includes the path to the executable that was built.
[#6363](https://github.com/rust-lang/cargo/pull/6363)
- The man pages have been rewritten, and are now published with the web
documentation. [#6405](https://github.com/rust-lang/cargo/pull/6405)
- `cargo login` now displays a confirmation after saving the token.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- A warning is now emitted if a `[patch]` entry does not match any package.
[#6470](https://github.com/rust-lang/cargo/pull/6470)
- `cargo metadata` now includes the `links` key for a package.
[#6480](https://github.com/rust-lang/cargo/pull/6480)
- "Very verbose" output with `-vv` now displays the environment variables that
cargo sets when it runs a process.
[#6492](https://github.com/rust-lang/cargo/pull/6492)
- `--example`, `--bin`, `--bench`, or `--test` without an argument now lists
the available targets for those options.
[#6505](https://github.com/rust-lang/cargo/pull/6505)
- Windows: If a process fails with an extended status exit code, a
human-readable name for the code is now displayed.
[#6532](https://github.com/rust-lang/cargo/pull/6532)
- Added `--features`, `--no-default-features`, and `--all-features` flags to
the `cargo package` and `cargo publish` commands to use the given features
when verifying the package.
[#6453](https://github.com/rust-lang/cargo/pull/6453)
### Changed
- If `cargo fix` fails to compile the fixed code, the rustc errors are now
displayed on the console.
[#6419](https://github.com/rust-lang/cargo/pull/6419)
- Hide the `--host` flag from `cargo login`, it is unused.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- Build script fingerprints now include the rustc version.
[#6473](https://github.com/rust-lang/cargo/pull/6473)
- macOS: Switched to setting `DYLD_FALLBACK_LIBRARY_PATH` instead of
`DYLD_LIBRARY_PATH`. [#6355](https://github.com/rust-lang/cargo/pull/6355)
- `RUSTFLAGS` is now included in the metadata hash, meaning that changing
the flags will not overwrite previously built files.
[#6503](https://github.com/rust-lang/cargo/pull/6503)
- When updating the crate graph, unrelated yanked crates were erroneously
removed. They are now kept at their original version if possible. This was
causing unrelated packages to be downgraded during `cargo update -p
somecrate`. [#5702](https://github.com/rust-lang/cargo/issues/5702)
- TOML files now support the [0.5 TOML
syntax](https://github.com/toml-lang/toml/blob/master/CHANGELOG.md#050--2018-07-11).
### Fixed
- `cargo fix` will now ignore suggestions that modify multiple files.
[#6402](https://github.com/rust-lang/cargo/pull/6402)
- `cargo fix` will now only fix one target at a time, to deal with targets
which share the same source files.
[#6434](https://github.com/rust-lang/cargo/pull/6434)
- Fixed bash completion showing the list of cargo commands.
[#6461](https://github.com/rust-lang/cargo/issues/6461)
- `cargo init` will now avoid creating duplicate entries in `.gitignore`
files. [#6521](https://github.com/rust-lang/cargo/pull/6521)
- Builds now attempt to detect if a file is modified in the middle of a
compilation, allowing you to build again and pick up the new changes. This
is done by keeping track of when the compilation *starts* not when it
finishes. Also, [#5919](https://github.com/rust-lang/cargo/pull/5919) was
reverted, meaning that cargo does *not* treat equal filesystem mtimes as
requiring a rebuild. [#6484](https://github.com/rust-lang/cargo/pull/6484)
### Nightly only
- Allow using registry *names* in `[patch]` tables instead of just URLs.
[#6456](https://github.com/rust-lang/cargo/pull/6456)
- `cargo metadata` added the `registry` key for dependencies.
[#6500](https://github.com/rust-lang/cargo/pull/6500)
- Registry names are now restricted to the same style as
package names (alphanumeric, `-` and `_` characters).
[#6469](https://github.com/rust-lang/cargo/pull/6469)
- `cargo login` now displays the `/me` URL from the registry config.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- `cargo login --registry=NAME` now supports interactive input for the token.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- Registries may now elide the `api` key from `config.json` to indicate they
do not support API access.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- Fixed panic when using `--message-format=json` with metabuild.
[#6432](https://github.com/rust-lang/cargo/pull/6432)
- Fixed detection of publishing to crates.io when using alternate registries.
[#6525](https://github.com/rust-lang/cargo/pull/6525)
## Cargo 1.32 (2019-01-17)
[339d9f9c...8610973a](https://github.com/rust-lang/cargo/compare/339d9f9c...8610973a)
### Added
- Registries may now display warnings after a successful publish.
[#6303](https://github.com/rust-lang/cargo/pull/6303)
- Added a [glossary](https://doc.rust-lang.org/cargo/appendix/glossary.html)
to the documentation. [#6321](https://github.com/rust-lang/cargo/pull/6321)
- Added the alias `c` for `cargo check`.
[#6218](https://github.com/rust-lang/cargo/pull/6218)
### Changed
- 🔥 HTTP/2 multiplexing is now enabled by default. The `http.multiplexing`
config value may be used to disable it.
[#6271](https://github.com/rust-lang/cargo/pull/6271)
- Use ANSI escape sequences to clear lines instead of spaces.
[#6233](https://github.com/rust-lang/cargo/pull/6233)
- Disable git templates when checking out git dependencies, which can cause
problems. [#6252](https://github.com/rust-lang/cargo/pull/6252)
- Include the `--update-head-ok` git flag when using the
`net.git-fetch-with-cli` option. This can help prevent failures when
fetching some repositories.
[#6250](https://github.com/rust-lang/cargo/pull/6250)
- When extracting a crate during the verification step of `cargo package`, the
filesystem mtimes are no longer set, which was failing on some rare
filesystems. [#6257](https://github.com/rust-lang/cargo/pull/6257)
- `crate-type = ["proc-macro"]` is now treated the same as `proc-macro = true`
in `Cargo.toml`. [#6256](https://github.com/rust-lang/cargo/pull/6256)
- An error is raised if `dependencies`, `features`, `target`, or `badges` is
set in a virtual workspace. Warnings are displayed if `replace` or `patch`
is used in a workspace member.
[#6276](https://github.com/rust-lang/cargo/pull/6276)
- Improved performance of the resolver in some cases.
[#6283](https://github.com/rust-lang/cargo/pull/6283)
[#6366](https://github.com/rust-lang/cargo/pull/6366)
- `.rmeta` files are no longer hard-linked into the base target directory
(`target/debug`). [#6292](https://github.com/rust-lang/cargo/pull/6292)
- A warning is issued if multiple targets are built with the same output
filenames. [#6308](https://github.com/rust-lang/cargo/pull/6308)
- When using `cargo build` (without `--release`) benchmarks are now built
using the "test" profile instead of "bench". This makes it easier to debug
benchmarks, and avoids confusing behavior.
[#6309](https://github.com/rust-lang/cargo/pull/6309)
- User aliases may now override built-in aliases (`b`, `r`, `t`, and `c`).
[#6259](https://github.com/rust-lang/cargo/pull/6259)
- Setting `autobins=false` now disables auto-discovery of inferred targets.
[#6329](https://github.com/rust-lang/cargo/pull/6329)
- `cargo verify-project` will now fail on stable if the project uses unstable
features. [#6326](https://github.com/rust-lang/cargo/pull/6326)

[#6328](https://github.com/rust-lang/cargo/pull/6328)
- Fixed `cargo run --example NAME` to work correctly if the example sets
`crate_type = ["bin"]`.
[#6330](https://github.com/rust-lang/cargo/pull/6330)

--open`. This should more reliably select the system-preferred browser on
all platforms. [#5888](https://github.com/rust-lang/cargo/pull/5888)
