v4.39.0

• Breaking change: Bump the minimum required CodeQL bundle version to 2.20.7. #4205
• The codeql-action/analyze step now validates that a correct argument for the checkout_path input has been provided. The checkout_path input must be set to the path where the repository that is being analyzed is checked out at on the runner, if that path is something other than the workspace root. If the path does not point to a repository checkout or is different from the path that was used by codeql-action/init, then the CodeQL Action now produces a warning. #4148
• Resolved an issue with third-party caching implementations that prevented caches from being restored correctly. #4206
• The codeql-action/start-proxy step that is used in Code Scanning Default Setup now finds CodeQL releases using the same logic as codeql-action/init. This primarily benefits customers who are using GitHub instances other than github.com where the codeql-action/start-proxy step may previously have been unable to locate recent releases and ended up using outdated versions of the private registry authentication proxy as a result. #4198

4.38.3 - 08 Oct 2026

• Upcoming breaking change: CodeQL version 2.21.2 and earlier were discontinued on 24 September 2026 alongside GitHub Enterprise Server 3.17, and will be unsupported by the next minor release of the CodeQL Action. Added a deprecation warning for customers using these versions of CodeQL. #4188
• Update default CodeQL bundle version to 2.27.2. #4203
• Fixed a bug where the decision of whether to use a per-language bundle did not account for custom configurations that reference queries outside of compiled CodeQL packs. This issue was caught during internal testing and did not affect any customer repositories. We will resume the roll out of per-language bundles in the coming weeks. #4184

4.38.2 - 24 Sept 2026

• Update default CodeQL bundle version to 2.27.1. #4160

4.38.1 - 18 Sept 2026

• The CodeQL Action now has experimental support for CodeQL releases for which per-language bundles are available. Per-language bundles support analysis for a single language and are therefore smaller than the combined bundles that allow analysis for all supported languages. As a result, per-language bundles take up less space on disk and are faster to download. We expect to roll this change out to everyone in the coming weeks. #4146

4.38.0 - 09 Sept 2026

• On GitHub-hosted runners, the CodeQL Action now deletes unused CodeQL bundles from the toolcache before downloading a different bundle, which frees up disk space for the analysis. We expect to roll this change out to everyone in September. #4124
• The CodeQL Action now supports CodeQL releases that are compatible with Linux Arm64 and downloads the native linux-arm64 CodeQL bundle when available. #4072
• Update default CodeQL bundle version to 2.27.0. #4129

4.37.9 - 26 Aug 2026

• Update default CodeQL bundle version to 2.26.4. #4106

4.37.8 - 21 Aug 2026

No user facing changes.

4.37.7 - 13 Aug 2026

• Update default CodeQL bundle version to 2.26.3. #4085

4.37.6 - 04 Aug 2026

• Changed the default filepath for the new remote file address format that was introduced in CodeQL Action 4.37.0 / 3.37.0 to .github/codeql-config.yml to align it with the suggested path that is used elsewhere. #4070
