Release Notes

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
