Merge pull request #15 from actions-rust-lang/fix-problem-matcher

The action runner currently fails to strip color codes from the output.
This means that many matchers currectly do not work.

https://github.com/actions/runner/issues/2341
https://github.com/actions/runner/pull/2430

The new matcher is copied from kaj/rsass which is MIT licensed.

 ## [Unreleased]
 
+## [1.4.4] - 2023-03-18
+
+### Fixed
+
+* Use color aware problem matcher.
+    The problem matcher currently runs against the colored terminal output ([Bug 1](https://github.com/actions/runner/issues/2341), [Bug 2](https://github.com/actions/runner/pull/2430)).
+    The previous matcher was not aware of ANSII color codes and did not work.
+
+## [1.4.3] - 2023-02-21
+
+### Fixed
+
+* Executing the action twice for different toolchains now no longer fails around unstable features #12.
+    If multiple toolchains are installed, the "CARGO_REGISTRIES_CRATES_IO_PROTOCOL" can be downgraded to "git" if any of the installed toolchains require it.
+
+## [1.4.2] - 2023-02-15
+
+### Fixed
+
+* Tweak sparse registry version regex to better work with 1.68 nightly versions.
+* Fix command not found issue
+
+## [1.4.1] - 2023-02-13
+
+### Fixed
+
+* Fixed running on macOS #9 #10
+    The macOS images have an ancient version of bash, but the action relies on "newer" features than 2014.
+    We install bash via brew (already pre-installed) to have a new enough version.
+
+    The CI is extended to also run on Windows and macOS to catch such issues earlier in the future.
+
+    Thanks to @GeorgeHahn for reporting the issue.
+
+## [1.4.0] - 2023-02-13
+
+### Changed
+
+* Only set environment variables, if they are not set before.
+    This allows setting environment variables before using this action and keeping their values.
+* Enable stable sparse registry, except on versions 1.66 and 1.67 where this leads to errors.
+
+## [1.3.7] - 2023-01-31
+
+### Fixed
+
+* Disable the stable access to the sparse registry.
+    Setting the value causes problem on version before stabilization, e.g., 1.67.
+    For example, "cargo add" fails.
+
+## [1.3.6] - 2023-01-31
+
+### Fixed
+
+* The the correct environment variable to enable the sparse registry access.
+    The pull request originally had the wrong value, without `CARGO_` prefix.
+
+## [1.3.5] - 2023-01-21
+
+### Changed
+
+* Use the newly stabilized setting to enable sparse registry access.
+    This speeds up access to the crate registry and is in addition to the unstable nightly env var.
+    <https://github.com/rust-lang/cargo/pull/11224>
+
+## [1.3.4] - 2022-10-15
+
+### Changed
+
+* The last version did not fix all "set-output" commands
+
+## [1.3.3] - 2022-10-13
+
+### Changed
+
+* Switch from set-output to $GITHUB_OUTPUT to avoid warning
+    https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/
+
+## [1.3.2] - 2022-09-15
+
+### Fixed
+
+* Fix setting `$CARGO_HOME` to a valid path, in case rustup is installed from the internet.
+    Thanks to @nahsi for providing the fix.
+
+## [1.3.1] - 2022-08-14
+
+### Changed
+
+* Use the sparse-registry on nightly for faster access to the crate registry on nightly.
+    <https://internals.rust-lang.org/t/call-for-testing-cargo-sparse-registry/16862>
+
+## [1.3.0] - 2022-07-30
+
+### Added
+
+* An option to disable configuring Rust cache.
+    Thanks to @filips123 for the PR.
+
+## [1.2.1] - 2022-07-29
+
+### Fixed
+
+* Set environment variables before invoking the cache action.
+    This ensures restoring and saving are using the same cache key.
+
+## [1.2.0] - 2022-07-21
+
+### Added
+
+* Prefer toolchain definitions in `rust-toolchain` or `rust-toolchain.toml` files ([Toolchain File](https://rust-lang.github.io/rustup/overrides.html#the-toolchain-file)).
+    Other input values are ignored if either file is found.
+
+## [1.1.0] - 2022-07-19
+
+### Added
+
+* Install rustup if not available in the CI environment. (Linux only)
+    The code is taken from this issue: <https://github.com/dtolnay/rust-toolchain/pull/8>
+* Add rustc version output suitable as a cache key.
+    This is based on <https://github.com/dtolnay/rust-toolchain/pull/20> and <https://github.com/dtolnay/rust-toolchain/pull/17>.
+
+### Changed
+
+* Update to `Swatinem/rust-cache@v2`.
+
+## [1.0.2] - 2022-05-02
+
+### Changed
+
+* Enable colored cargo output.
+* Print short backtraces during test failure.
+
 ## [1.0.1] - 2022-04-20
