Sourced from github/codeql-action's releases.

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

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

v4.35.1

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

v4.35.0

• 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

v4.34.1

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

v4.34.0

• 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

v4.33.0

• 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

  To opt out of this change:

  • Repositories owned by an organization: Create a custom repository property with the name github-codeql-file-coverage-on-prs and the type "True/false", then set this property to true in the repository's settings. For more information, see Managing custom properties for repositories in your organization. Alternatively, if you are using an advanced setup workflow, you can set the CODEQL_ACTION_FILE_COVERAGE_ON_PRS environment variable to true in your workflow.
  • User-owned repositories using default setup: Switch to an advanced setup workflow and set the CODEQL_ACTION_FILE_COVERAGE_ON_PRS environment variable to true in your workflow.
  • User-owned repositories using advanced setup: Set the CODEQL_ACTION_FILE_COVERAGE_ON_PRS environment variable to true in your workflow.
