v4.36.1

No user facing changes.

v4.36.0

• Breaking change: Bump the minimum required CodeQL bundle version to 2.19.4. #3894
• Add support for SHA-256 Git object IDs. #3893
• Update default CodeQL bundle version to 2.25.5. #3926

v4.35.5

• We have improved how the JavaScript bundles for the CodeQL Action are generated to avoid duplication across bundles and reduce the size of the repository by around 70%. This should have no effect on the runtime behaviour of the CodeQL Action. #3899
• For performance and accuracy reasons, improved incremental analysis will now only be enabled on a pull request when diff-informed analysis is also enabled for that run. If diff-informed analysis is unavailable (for example, because the PR diff ranges could not be computed), the action will fall back to a full analysis. #3791
• If multiple inputs are provided for the GitHub-internal analysis-kinds input, only code-scanning will be enabled. The analysis-kinds input is experimental, for GitHub-internal use only, and may change without notice at any time. #3892
• Added an experimental change which, when running a Code Scanning analysis for a PR with improved incremental analysis enabled, prefers CodeQL CLI versions that have a cached overlay-base database for the configured languages. This speeds up analysis for a repository when there is not yet a cached overlay-base database for the latest CLI version. We expect to roll this change out to everyone in May. #3880

v4.35.4

• Update default CodeQL bundle version to 2.25.4. #3881

v4.35.3

• Upcoming breaking change: Add a deprecation warning for customers using CodeQL version 2.19.3 and earlier. These versions of CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise Server 3.15, and will be unsupported by the next minor release of the CodeQL Action. #3837
• Configurations for private registries that use Cloudsmith or GCP OIDC are now accepted. #3850
• Best-effort connection tests for private registries now use GET requests instead of HEAD for better compatibility with various registry implementations. For NuGet feeds, the test is now always performed against the service index. #3853
• Fixed a bug where two diagnostics produced within the same millisecond could overwrite each other on disk, causing one of them to be lost. #3852
• Update default CodeQL bundle version to 2.25.3. #3865

• Add support for SHA-256 Git object IDs. #3893
• Update default CodeQL bundle version to 2.25.5. #3926

4.35.5 - 15 May 2026

• We have improved how the JavaScript bundles for the CodeQL Action are generated to avoid duplication across bundles and reduce the size of the repository by around 70%. This should have no effect on the runtime behaviour of the CodeQL Action. #3899

4.35.4 - 07 May 2026

• Update default CodeQL bundle version to 2.25.4. #3881

4.35.3 - 01 May 2026

• Upcoming breaking change: Add a deprecation warning for customers using CodeQL version 2.19.3 and earlier. These versions of CodeQL were discontinued on 9 April 2026 alongside GitHub Enterprise Server 3.15, and will be unsupported by the next minor release of the CodeQL Action. #3837

• Update default CodeQL bundle version to 2.25.3. #3865

4.35.2 - 15 Apr 2026

• The undocumented TRAP cache cleanup feature that could be enabled using the CODEQL_ACTION_CLEANUP_TRAP_CACHES environment variable is deprecated and will be removed in May 2026. If you are affected by this, we recommend disabling TRAP caching by passing the trap-caching: false input to the init Action. #3795
• The Git version 2.36.0 requirement for improved incremental analysis now only applies to repositories that contain submodules. #3789
• Python analysis on GHES no longer extracts the standard library, relying instead on models of the standard library. This should result in significantly faster extraction and analysis times, while the effect on alerts should be minimal. #3794
• Fixed a bug in the validation of OIDC configurations for private registries that was added in CodeQL Action 4.33.0 / 3.33.0. #3807
• Update default CodeQL bundle version to 2.25.2. #3823

4.35.1 - 27 Mar 2026

• Fix incorrect minimum required Git version for improved incremental analysis: it should have been 2.36.0, not 2.11.0. #3781

4.35.0 - 27 Mar 2026
