Release Notes

github/codeql-action (github/codeql-action)

v4.38.3

Compare Source

• 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

v4.38.2

Compare Source

• Update default CodeQL bundle version to 2.27.1. #​4160

v4.38.1

Compare Source

• 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

v4.38.0

Compare Source

• 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
