## [Unreleased]
## [0.4.4] - 2022-05-30
- Add `--fail-uncovered-{lines,regions,functions}` options to set the exit code based on uncovered {lines,regions,functions}. ([#173](https://github.com/taiki-e/cargo-llvm-cov/pull/173))
- Add `--ignore-run-fail` option to generate coverage even if tests fail. ([#174](https://github.com/taiki-e/cargo-llvm-cov/pull/174))
## [0.4.3] - 2022-05-29
- Fix metadata for cargo binstall. ([#176](https://github.com/taiki-e/cargo-llvm-cov/pull/176))
## [0.4.2] - 2022-05-29
- Add metadata for cargo binstall. ([#175](https://github.com/taiki-e/cargo-llvm-cov/pull/175), thanks @vmiklos)
## [0.4.1] - 2022-05-24
- Add `--coverage-target-only` flag to use rustflags only for target. ([#167](https://github.com/taiki-e/cargo-llvm-cov/pull/167), thanks @haraldh)
## [0.4.0] - 2022-05-12
- cargo-llvm-cov no longer changes the current directory when running cargo. ([#161](https://github.com/taiki-e/cargo-llvm-cov/pull/161))
- Exclude build script from report by default. ([#163](https://github.com/taiki-e/cargo-llvm-cov/pull/163))
You can use `--include-build-script` flag to include build script in report.
- Set `cfg(coverage_nightly)` when nightly compiler is used. ([#164](https://github.com/taiki-e/cargo-llvm-cov/pull/164))
- Support short flags of `--release` (`-r`) and `--features` (`-F`). ([#165](https://github.com/taiki-e/cargo-llvm-cov/pull/165))
- Support [custom profiles](https://doc.rust-lang.org/cargo/reference/profiles.html#custom-profiles). ([#166](https://github.com/taiki-e/cargo-llvm-cov/pull/166))
## [0.3.3] - 2022-05-06
- Fix an issue where codes in the target directory are not being properly excluded from reports when using `show-env` subcommand. ([#156](https://github.com/taiki-e/cargo-llvm-cov/pull/156))
## [0.3.2] - 2022-05-05
- Alleviate an issue where "File name or extension is too long" error occurs in Windows. ([#155](https://github.com/taiki-e/cargo-llvm-cov/pull/155))
## [0.3.1] - 2022-05-01
- Calculate `--show-missing-lines` based on function regions. ([#150](https://github.com/taiki-e/cargo-llvm-cov/pull/150), thanks @vmiklos)
## [0.3.0] - 2022-04-08
- cargo-llvm-cov now always select the current toolchain. ([#148](https://github.com/taiki-e/cargo-llvm-cov/pull/148))
Previously, if `-C instrument-coverage` is not available in the current toolchain, the nightly toolchain was used. (See [release note of 0.2.0](https://github.com/taiki-e/cargo-llvm-cov/releases/tag/v0.2.0) for more information on the previous behavior.)
- Make `--remap-path-prefix` optional. ([#141](https://github.com/taiki-e/cargo-llvm-cov/pull/141))
Previously this flag was always used, but due to some bugs discovered we decided to disable it by default. If you were dependent on the behavior provided by this flag, you can use the same behavior by passing the `--remap-path-prefix` flag to cargo-llvm-cov.
- Stabilize a few unstable options.
## [0.2.4] - 2022-03-18
- Add support for `nextest`. ([#144](https://github.com/taiki-e/cargo-llvm-cov/pull/144), thanks @skyzh)
## [0.2.3] - 2022-03-05
- Add `--show-missing-lines` option to show uncovered lines in the command-line output. ([#143](https://github.com/taiki-e/cargo-llvm-cov/pull/143), thanks @vmiklos)
## [0.2.2] - 2022-03-01
- Add `--fail-under-lines` option to set the exit code based on coverage percentage. ([#139](https://github.com/taiki-e/cargo-llvm-cov/pull/139), thanks @vmiklos)
## [0.2.1] - 2022-02-18
- Update clap to 3.1. ([#136](https://github.com/taiki-e/cargo-llvm-cov/pull/136))
## [0.2.0] - 2022-02-06
- Update to stabilized `-C instrument-coverage`. ([#130](https://github.com/taiki-e/cargo-llvm-cov/pull/130))
Support for `-Z instrument-coverage` in the old nightly will also be kept for compatibility.
**Compatibility Note:** In 0.2, if `-C instrument-coverage` or `-Z instrument-coverage` is not available in the default toolchain, running `cargo llvm-cov` will find and use nightly (this is almost the same behavior as 0.1). This behavior is necessary because only the recent nightly currently supports `-C instrument-coverage` (and also for compatibility with 0.1). This behavior will be changed in 0.3 to always select the default toolchain. If you are likely to be affected by the change in 0.3, cargo-llvm-cov will emit a warning. 0.3 is planned to be released after `-C instrument-coverage` is available in the stable toolchain.
- Remove support of multiple values in `--package` and `--exclude`. ([#133](https://github.com/taiki-e/cargo-llvm-cov/pull/133))
[This behavior was unintentionally enabled in the older version of 0.1 and was deprecated in the recent version of 0.1.](https://github.com/taiki-e/cargo-llvm-cov/pull/127#issuecomment-1018204521)
- Add `--exclude-from-test` option to exclude specific packages from the test but not from the report. ([#131](https://github.com/taiki-e/cargo-llvm-cov/pull/131))
- Add `--exclude-from-report` option to exclude specific packages from the report but not from the test. ([#131](https://github.com/taiki-e/cargo-llvm-cov/pull/131))
- Workspace members are now always included in the report unless specified by `--exclude` or `--exclude-from-report`. ([#131](https://github.com/taiki-e/cargo-llvm-cov/pull/131))
## [0.1.16] - 2022-01-21
- Alleviate an issue where "File name or extension is too long" error occurs in Windows. ([#126](https://github.com/taiki-e/cargo-llvm-cov/pull/126), thanks @aganders3)
- Re-enable multiple values for `--package` and `--exclude`. ([#127](https://github.com/taiki-e/cargo-llvm-cov/pull/127), thanks @aganders3)
This behavior was unintentionally enabled in older versions and disabled in recent versions.
We will support this again in 0.1.x for compatibility, but will remove it in 0.2.x.
