# Changelog
## Cargo 1.36 (2019-07-04)
[6f3e9c36...HEAD](https://github.com/rust-lang/cargo/compare/6f3e9c36...HEAD)
### Added
- (Nightly only): Added [`-Z install-upgrade`
feature](https://github.com/rust-lang/cargo/blob/7b13469ee90a24fa5aa06166d447dac3370846ef/src/doc/src/reference/unstable.md#install-upgrade)
to track details about installed crates and to automatically update them if
they are out-of-date. [#6798](https://github.com/rust-lang/cargo/pull/6798)
- (Nightly only): Added the [`public-dependency`
feature](https://github.com/rust-lang/cargo/blob/7b13469ee90a24fa5aa06166d447dac3370846ef/src/doc/src/reference/unstable.md#public-dependency)
which allows tracking public versus private dependencies.
[#6772](https://github.com/rust-lang/cargo/pull/6772)
### 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)
- (Nightly only): 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)
- 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)
- Resolver performance improvements for some cases.
[#6853](https://github.com/rust-lang/cargo/pull/6853)
### 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)
## 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)
Fix a minor mistake in the changelog.
2019-05-14 23:44:05 +00:00
- (Nightly only): `cargo clippy-preview` is now a built-in cargo command.
Add a changelog.
2019-04-27 19:16:20 +00:00
[#6759](https://github.com/rust-lang/cargo/pull/6759)
### 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)
- (Nightly only): The `build-override` profile setting now includes
proc-macros and their dependencies.
[#6811](https://github.com/rust-lang/cargo/pull/6811)
- Resolver performance improvements for some cases.
[#6776](https://github.com/rust-lang/cargo/pull/6776)
- (Nightly only): Optional and target dependencies now work better with `-Z
offline`. [#6814](https://github.com/rust-lang/cargo/pull/6814)
### 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)
## 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)
- (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 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)
- (Nightly only): 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)
- 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)
## 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)
- (Nightly only): Allow using registry *names* in `[patch]` tables instead of
just URLs. [#6456](https://github.com/rust-lang/cargo/pull/6456)
- `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)
- (Nightly only): `cargo metadata` added the `registry` key for dependencies.
[#6500](https://github.com/rust-lang/cargo/pull/6500)
- "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)
- (Nightly only): Registry names are now restricted to the same style as
package names (alphanumeric, `-` and `_` characters).
[#6469](https://github.com/rust-lang/cargo/pull/6469)
- (Nightly only): `cargo login` now displays the `/me` URL from the registry
config. [#6466](https://github.com/rust-lang/cargo/pull/6466)
- Hide the `--host` flag from `cargo login`, it is unused.
[#6466](https://github.com/rust-lang/cargo/pull/6466)
- (Nightly only): `cargo login --registry=NAME` now supports interactive input
for the token. [#6466](https://github.com/rust-lang/cargo/pull/6466)
- (Nightly only): 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)
- 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)
- (Nightly only): Fixed panic when using `--message-format=json` with metabuild.
[#6432](https://github.com/rust-lang/cargo/pull/6432)
- 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)
- (Nightly only): Fixed detection of publishing to crates.io when using
alternate registries. [#6525](https://github.com/rust-lang/cargo/pull/6525)
- 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)
## 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)
- (Nightly only): Added `"compile_mode"` key to the build-plan JSON structure
to be able to distinguish running a custom build script versus compiling the
build script. [#6331](https://github.com/rust-lang/cargo/pull/6331)
### 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)
- Platform targets with an internal `.` within the name are now allowed.
[#6255](https://github.com/rust-lang/cargo/pull/6255)
- `cargo clean --release` now only deletes the release directory.
[#6349](https://github.com/rust-lang/cargo/pull/6349)
### Fixed
- Avoid adding extra angle brackets in email address for `cargo new`.
[#6243](https://github.com/rust-lang/cargo/pull/6243)
- The progress bar is disabled if the CI environment variable is set.
[#6281](https://github.com/rust-lang/cargo/pull/6281)
- Avoid retaining all rustc output in memory.
[#6289](https://github.com/rust-lang/cargo/pull/6289)
- If JSON parsing fails, and rustc exits nonzero, don't lose the parse failure
message. [#6290](https://github.com/rust-lang/cargo/pull/6290)
- (Nightly only): `--out-dir` no longer copies over build scripts.
[#6300](https://github.com/rust-lang/cargo/pull/6300)
- Fixed renaming a project directory with build scripts.
[#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)
- Fixed issue with `cargo package` git discovery being too aggressive. The
`--allow-dirty` now completely disables the git repo checks.
[#6280](https://github.com/rust-lang/cargo/pull/6280)
- Fixed build change tracking for `[patch]` deps which resulted in `cargo
build` rebuilding when it shouldn't.
[#6493](https://github.com/rust-lang/cargo/pull/6493)
Fix typo

[524a578d...36d96825](https://github.com/rust-lang/cargo/compare/524a578d...36d96825)
### Added
- 🔥 Added an animated progress bar shows progress during building.
[#5995](https://github.com/rust-lang/cargo/pull/5995/)
- Added `resolve.nodes.deps` key to `cargo metadata`, which includes more
information about resolved dependencies, and properly handles renamed
dependencies. [#5871](https://github.com/rust-lang/cargo/pull/5871)
- When creating a package, provide more detail with `-v` when failing to
discover if files are dirty in a git repository. Also fix a problem with
discovery on Windows. [#5858](https://github.com/rust-lang/cargo/pull/5858)
- Filters like `--bin`, `--test`, `--example`, `--bench`, or `--lib` can be
used in a workspace without selecting a specific package.
[#5873](https://github.com/rust-lang/cargo/pull/5873)
- `cargo run` can be used in a workspace without selecting a specific package.
[#5877](https://github.com/rust-lang/cargo/pull/5877)
- `cargo doc --message-format=json` now outputs JSON messages from rustdoc.
[#5878](https://github.com/rust-lang/cargo/pull/5878)
- Added `--message-format=short` to show one-line messages.
[#5879](https://github.com/rust-lang/cargo/pull/5879)
- Added `.cargo_vcs_info.json` file to `.crate` packages that captures the
current git hash. [#5886](https://github.com/rust-lang/cargo/pull/5886)
- Added `net.git-fetch-with-cli` configuration option to use the `git`
executable to fetch repositories instead of using the built-in libgit2
library. [#5914](https://github.com/rust-lang/cargo/pull/5914)
- Added `required-features` to `cargo metadata`.
[#5902](https://github.com/rust-lang/cargo/pull/5902)
- `cargo uninstall` within a package will now uninstall that package.
[#5927](https://github.com/rust-lang/cargo/pull/5927)
- (Nightly only): Added
[metabuild](https://doc.rust-lang.org/1.30.0/cargo/reference/unstable.html#metabuild).
[#5628](https://github.com/rust-lang/cargo/pull/5628)
- Added `--allow-staged` flag to `cargo fix` to allow it to run if files are
staged in git. [#5943](https://github.com/rust-lang/cargo/pull/5943)
- Added `net.low-speed-limit` config value, and also honor `net.timeout` for
http operations. [#5957](https://github.com/rust-lang/cargo/pull/5957)
- Added `--edition` flag to `cargo new`.
[#5984](https://github.com/rust-lang/cargo/pull/5984)
- Temporarily stabilized 2018 edition support for the duration of the beta.
[#5984](https://github.com/rust-lang/cargo/pull/5984)
[#5989](https://github.com/rust-lang/cargo/pull/5989)
- Added support for `target.'cfg(…)'.runner` config value to specify the
run/test/bench runner for config-expressioned targets.
[#5959](https://github.com/rust-lang/cargo/pull/5959)
### Changed
- Windows: `cargo run` will not kill child processes when the main process
exits. [#5887](https://github.com/rust-lang/cargo/pull/5887)
- Switched to the `opener` crate to open a web browser with `cargo doc
--open`. This should more reliably select the system-preferred browser on
all platforms. [#5888](https://github.com/rust-lang/cargo/pull/5888)
- Equal file mtimes now cause a target to be rebuilt. Previously only if files
were strictly *newer* than the last build would it cause a rebuild.
[#5919](https://github.com/rust-lang/cargo/pull/5919)
- Ignore `build.target` config value when running `cargo install`.
[#5874](https://github.com/rust-lang/cargo/pull/5874)
- Ignore `RUSTC_WRAPPER` for `cargo fix`.
[#5983](https://github.com/rust-lang/cargo/pull/5983)
- Ignore empty `RUSTC_WRAPPER`.
[#5985](https://github.com/rust-lang/cargo/pull/5985)
### Fixed
- Fixed error when creating a package with an edition field in `Cargo.toml`.
[#5908](https://github.com/rust-lang/cargo/pull/5908)
- More consistently use relative paths for path dependencies in a workspace.
[#5935](https://github.com/rust-lang/cargo/pull/5935)
- `cargo fix` now always runs, even if it was run previously.
[#5944](https://github.com/rust-lang/cargo/pull/5944)
- Windows: Attempt to more reliably detect terminal width. msys-based
terminals are forced to 60 characters wide.
[#6010](https://github.com/rust-lang/cargo/pull/6010)
- Allow multiple target flags with `cargo doc --document-private-items`.
