v4.35.2

• 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

4.35.4 - 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
• 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

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

• Reduced the minimum Git version required for improved incremental analysis from 2.38.0 to 2.11.0. #3767
• Update default CodeQL bundle version to 2.25.1. #3773

4.34.1 - 20 Mar 2026

• Downgrade default CodeQL bundle version to 2.24.3 due to issues with a small percentage of Actions and JavaScript analyses. #3762

4.34.0 - 20 Mar 2026

• Added an experimental change which disables TRAP caching when improved incremental analysis is enabled, since improved incremental analysis supersedes TRAP caching. This will improve performance and reduce Actions cache usage. We expect to roll this change out to everyone in March. #3569
• We are rolling out improved incremental analysis to C/C++ analyses that use build mode none. We expect this rollout to be complete by the end of April 2026. #3584
• Update default CodeQL bundle version to 2.25.0. #3585

4.33.0 - 16 Mar 2026

• Upcoming change: Starting April 2026, the CodeQL Action will skip collecting file coverage information on pull requests to improve analysis performance. File coverage information will still be computed on non-PR analyses. Pull request analyses will log a warning about this upcoming change. #3562
