## [Unreleased]

### :sparkles: Release Note <!-- optional -->

### :rocket: Enhancements
- [#2257](https://github.com/reviewdog/reviewdog/pull/2257) Use -trimpath flag for reproducible build
- [#2513](https://github.com/reviewdog/reviewdog/pull/2513) Drop support of windows/arm
- [#2543](https://github.com/reviewdog/reviewdog/pull/2543) Update `gitlab-mr-discussion` reporter to embed a fingerprint meta-comment in each posted note and automatically resolve previously-posted discussions whose diagnostic is no longer reported (fixes [#1150](https://github.com/reviewdog/reviewdog/issues/1150)).

### :bug: Fixes

- [#2586](https://github.com/reviewdog/reviewdog/pull/2586) Honor SARIF `result.suppressions` in SARIF parser — suppressed results (per SARIF 2.1.0 §3.27.23 / §3.35) no longer emit diagnostics
- [#2481](https://github.com/reviewdog/reviewdog/pull/2481) Use CWD instead of git root in SARIF parser to prevent path doubling

### :rotating_light: Breaking changes
- doghouse: the `/check` endpoint (used by `-reporter=github-pr-check` via reviewdog.app) now always requires `REVIEWDOG_TOKEN`. The previous shortcut that accepted requests from certain CI providers without a token has been removed. Users who relied on the token-less path (e.g. AppVeyor) must now set `REVIEWDOG_TOKEN` explicitly. Tokens can be obtained from `https://reviewdog.app/gh/<owner>/<repo-name>`.

## [v0.21.0] - 2025-09-03

### :sparkles: Release Note

Starting from this release, reviewdog enables [immutable releases](https://github.blog/changelog/2025-08-26-releases-now-support-immutability-in-public-preview/) to ensure the integrity of released assets. Released assets and the release itself are now immutable and can be verified using:

```bash
gh release verify <tag>
gh release verify-asset <tag> <asset>
```

### :rocket: Enhancements
- [#2026](https://github.com/reviewdog/reviewdog/pull/2026) Add reporter for GitHub annotations `github-annotations`. Same as `github-pr-annotations` but not restricted to pull requests.
- [#2131](https://github.com/reviewdog/reviewdog/pull/2131) Fetch GitHub git based diffs using the base pull request repo to allow fetching from private forks in GitHub Actions.
- [#2210](https://github.com/reviewdog/reviewdog/pull/2210) Update Gitea PR reporter to detect comments for already reported issues and report suggestions.
- [#1931](https://github.com/reviewdog/reviewdog/pull/1931) Refactor handling of Git relative path - Centralized path normalization logic and added automatic `--relative` flag to git diff commands for consistent relative path handling.

### :bug: Fixes
- [#967](https://github.com/reviewdog/reviewdog/pull/967) Fix parsing long lines in diffs #967
- [#1344](https://github.com/reviewdog/reviewdog/pull/1344) Bitbucket Cloud Fixes
- [#1983](https://github.com/reviewdog/reviewdog/pull/1983) Improve error message for diff command failure by including stderr output
- [#1975](https://github.com/reviewdog/reviewdog/pull/1975) Fix for suggestions not including an inserted EOF newline
- [#2026](https://github.com/reviewdog/reviewdog/pull/2026) Never filter diffs when running `github-[pr-][check|annotate]` on non-PRs
- [#2214](https://github.com/reviewdog/reviewdog/pull/2214) [#2231](https://github.com/reviewdog/reviewdog/pull/2231) Migrate install.sh from godownloader to [binstaller](https://github.com/binary-install/binstaller) to prevent future failures when .sbom.json files are added to release artifacts. While reviewdog releases don't currently include SBOM files, this preemptively fixes the grep pattern bug that would cause installation failures when they are added in the near future.

## [v0.20.3] - 2024-12-04

### :bug: Fixes
- [#1977](https://github.com/reviewdog/reviewdog/pull/1977) Include stderr in the error message if we run git command

## [v0.20.2] - 2024-09-16

### :rocket: Enhancements
- [#1845](https://github.com/reviewdog/reviewdog/pull/1845) Normalize file path in `related_locations` too.

### :bug: Fixes
- [#1846](https://github.com/reviewdog/reviewdog/issues/1846) Unexpected error
  exit code when using `-reporter=github-[pr-]check` with
  `-fail-on-error=true`. See the below breaking changes section for more details.
- [#1867](https://github.com/reviewdog/reviewdog/pull/1867) Tool name was incorrect for github-[pr-]check reporters and check API does not work correctly for project config based run
- [#1867](https://github.com/reviewdog/reviewdog/pull/1867) Deletion of outdated comment didn't work properly with github-pr-review reporter since tool name isn't correctly configured for project config based run
- [#1894](https://github.com/reviewdog/reviewdog/pull/1894) fix error when repository uses multiselect custom-properties [#1881](https://github.com/reviewdog/reviewdog/issues/1881)

### :rotating_light: Breaking changes
- [#1858](https://github.com/reviewdog/reviewdog/pull/1858) Remove original_output from rdjson/rdjsonl reporters' output

### :rotating_light: Deprecation Warnings
- [#1854](https://github.com/reviewdog/reviewdog/pull/1854) (Actually No Breaking changes) `-fail-on-error`
  flag is deprecated. Use `-fail-level=[none,any,error,warning,info]` flag
  instead. You can reproduce the same behavior with `-fail-level=any` for most
  reporters (reviewdog will exit with 1 if it find any severity level).
  As for `github-[pr-]check` reporter you can reproduce the same behavior with
  `-fail-level=error` ([#1846](https://github.com/reviewdog/reviewdog/issues/1846)).

  `-fail-on-error` is just deprecated and it's not removed yet. Please update
  the flag while it's working.
<!-- TODO: update the v0.19.0 release section -->

## [v0.20.1] - 2024-07-14

### :bug: Fixes
- [#1835](https://github.com/reviewdog/reviewdog/pull/1835) Fix -filter-mode
  didn't work with github-[pr-]check reporter for graceful degradation cases.
  i.e. GitHub token doesn't have write permission (e.g. PR from forked repo).

## [v0.20.0] - 2024-07-07

This version is created by mistake and is the same as v0.19.0.
We left both versions as-is so that it won't break existing clients who already use v0.20.0.

## [v0.19.0] - 2024-07-07

### :rocket: Enhancements
- [#1804](https://github.com/reviewdog/reviewdog/pull/1804) Support deleting
  outdated comments in github-pr-review reporter. Note that it won't delete
  comments if there is a reply considering there can be a meaningful
  discussion.
- [#1806](https://github.com/reviewdog/reviewdog/pull/1806) Add
  -reporter=rdjson/rdjsonl which outputs rdjson/rdjsonl format to stdout. It
  also changes the default behavior of -diff and -filter-mode for local
  reporters. If -filter-mode is not provided (-filter-mode=default) and -diff
  flag is not provided, reviewdog automatically set -filter-mode=nofilter.
- [#1807](https://github.com/reviewdog/reviewdog/pull/1807) Add -reporter=sarif
  which outputs SARIF format to stdout. You can upload the output SARIF to
  GitHub and see code scanning alerts.
- [#1809](https://github.com/reviewdog/reviewdog/pull/1809) Support posting
  comments outside diff context as a file comment in github-pr-review reporter

### :rotating_light: Breaking changes
- [#1846](https://github.com/reviewdog/reviewdog/issues/1846) the behavior of
  `-fail-on-error` changed with `-github-[pr-]check`. Previously, reviewdog
  didn't exit with 1 if it find issues with warning and info level. Now
  reviewdog will exit with 1 with any level.
  <!-- TODO: replace upcoming release with next released version -->
  The previous behavior can be restored with `-fail-level=error` flag with the
  upcoming release.

## [v0.10.0] - 2020-05-07

### :sparkles: Release Note

With v0.10.0 release, now reviewdog can find issues outside diff by controlling
filtering behavior with `-filter-mode`. Also, you can ensure to check reported
results by exit 1 with `-fail-on-error`.

Example
```shell
$ cd subdir/ && reviewdog -filter-mode=file -fail-on-error -reporter=github-pr-review
```

### :rocket: Enhancements
- [#446](https://github.com/reviewdog/reviewdog/issues/446)
  Added `-fail-on-error` flag
  ([document](https://github.com/reviewdog/reviewdog/tree/e359505275143ec85e9b114fc1ab4a4e91d04fb5#exit-codes))
  and improved exit code handling. ([@DmitryLanda](https://github.com/DmitryLanda), [@haya14busa])
- [#187](https://github.com/reviewdog/reviewdog/issues/187)
  Added `-filter-mode` flag [`added`, `diff_context`, `file`, `nofilter`]
  ([document](https://github.com/reviewdog/reviewdog/tree/e359505275143ec85e9b114fc1ab4a4e91d04fb5#filter-mode))
  which controls how reviewdog filter results. ([@Le6ow5k1](https://github.com/Le6ow5k1), [@haya14busa])
- [#69](https://github.com/reviewdog/reviewdog/issues/69) Support gerrit! ([@staticmukesh](https://github.com/staticmukesh))
