• 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.

• Fixed a bug which caused the CodeQL Action to fail loading repository properties if a "Multi select" repository property was configured for the repository. #​3557

• The CodeQL Action now loads custom repository properties on GitHub Enterprise Server, enabling the customization of features such as github-codeql-disable-overlay that was previously only available on GitHub.com. #​3559

• Once private package registries can be configured with OIDC-based authentication for organizations, the CodeQL Action will now be able to accept such configurations. #​3563

• Fixed the retry mechanism for database uploads. Previously this would fail with the error "Response body object should not be disturbed or locked". #​3564

• A warning is now emitted if the CodeQL Action detects a repository property whose name suggests that it relates to the CodeQL Action, but which is not one of the properties recognised by the current version of the CodeQL Action. #​3570

v4.32.6

• Update default CodeQL bundle version to 2.24.3. #​3548

v4.32.5

Compare Source

• Repositories owned by an organization can now set up the github-codeql-disable-overlay custom repository property to disable improved incremental analysis for CodeQL. First, create a custom repository property with the name github-codeql-disable-overlay and the type "True/false" in the organization's settings. Then in the repository's settings, set this property to true to disable improved incremental analysis. For more information, see Managing custom properties for repositories in your organization. This feature is not yet available on GitHub Enterprise Server. #​3507
• Added an experimental change so that when improved incremental analysis fails on a runner — potentially due to insufficient disk space — the failure is recorded in the Actions cache so that subsequent runs will automatically skip improved incremental analysis until something changes (e.g. a larger runner is provisioned or a new CodeQL version is released). We expect to roll this change out to everyone in March. #​3487
• The minimum memory check for improved incremental analysis is now skipped for CodeQL 2.24.3 and later, which has reduced peak RAM usage. #​3515
• Reduced log levels for best-effort private package registry connection check failures to reduce noise from workflow annotations. #​3516
• Added an experimental change which lowers the minimum disk space requirement for improved incremental analysis, enabling it to run on standard GitHub Actions runners. We expect to roll this change out to everyone in March. #​3498
• Added an experimental change which allows the start-proxy action to resolve the CodeQL CLI version from feature flags instead of using the linked CLI bundle version. We expect to roll this change out to everyone in March. #​3512
• The previously experimental changes from versions 4.32.3, 4.32.4, 3.32.3 and 3.32.4 are now enabled by default. #​3503, #​3504
