 See the [releases page](https://github.com/github/codeql-action/releases) for the relevant changes to the CodeQL CLI and language packs.

-## 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](https://github.com/github/codeql-action/pull/3899)
- For performance and accuracy reasons, [improved incremental analysis](https://github.com/github/roadmap/issues/1158) 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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3892)
- Added an experimental change which, when running a Code Scanning analysis for a PR with [improved incremental analysis](https://github.com/github/roadmap/issues/1158) 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](https://github.com/github/codeql-action/pull/3880)
-
-## 4.35.4 - 07 May 2026
-
- Update default CodeQL bundle version to [2.25.4](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.4). [#3881](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3837)
- Configurations for private registries that use Cloudsmith or GCP OIDC are now accepted. [#3850](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3852)
- Update default CodeQL bundle version to [2.25.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.3). [#3865](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3795)
- The Git version 2.36.0 requirement for improved incremental analysis now only applies to repositories that contain submodules. [#3789](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3807)
- Update default CodeQL bundle version to [2.25.2](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.2). [#3823](https://github.com/github/codeql-action/pull/3823)
-
-## 4.35.1 - 27 Mar 2026
-
- Fix incorrect minimum required Git version for [improved incremental analysis](https://github.com/github/roadmap/issues/1158): it should have been 2.36.0, not 2.11.0. [#3781](https://github.com/github/codeql-action/pull/3781)
-
-## 4.35.0 - 27 Mar 2026
+## 3.35.0 - 27 Mar 2026

 - Reduced the minimum Git version required for [improved incremental analysis](https://github.com/github/roadmap/issues/1158) from 2.38.0 to 2.11.0. [#3767](https://github.com/github/codeql-action/pull/3767)
 - Update default CodeQL bundle version to [2.25.1](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.25.1). [#3773](https://github.com/github/codeql-action/pull/3773)

-## 4.34.1 - 20 Mar 2026
+## 3.34.1 - 20 Mar 2026

 - Downgrade default CodeQL bundle version to [2.24.3](https://github.com/github/codeql-action/releases/tag/codeql-bundle-v2.24.3) due to issues with a small percentage of Actions and JavaScript analyses. [#3762](https://github.com/github/codeql-action/pull/3762)

-## 4.34.0 - 20 Mar 2026
+## 3.34.0 - 20 Mar 2026

 - Added an experimental change which disables TRAP caching when [improved incremental analysis](https://github.com/github/roadmap/issues/1158) 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](https://github.com/github/codeql-action/pull/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](https://github.com/github/codeql-action/pull/3584)

  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](https://docs.github.com/en/organizations/managing-organization-settings/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.

-
  - Alternatively, if you want to continue using a version of the CodeQL CLI between 2.13.5 and 2.14.5, you can replace `github/codeql-action/*@v3` by `github/codeql-action/*@v3.26.11` and `github/codeql-action/*@v2` by `github/codeql-action/*@v2.26.11` in your code scanning workflow to ensure you continue using this version of the CodeQL Action.

  Starting November 30, 2024, GitHub.com customers will [no longer be able to use `actions/download-artifact@v3`](https://github.blog/changelog/2024-04-16-deprecation-notice-v3-of-the-artifact-actions/). Therefore, to avoid breakage, customers who programmatically download the CodeQL Action debug artifacts should set the `CODEQL_ACTION_ARTIFACT_V4_UPGRADE` environment variable to `true` and bump `actions/download-artifact@v3` to `actions/download-artifact@v4` in their workflows. The CodeQL Action will enable this behavior by default in early November and workflows that have not yet bumped `actions/download-artifact@v3` to `actions/download-artifact@v4` will begin failing then.

  This change is currently unavailable for GitHub Enterprise Server customers, as `actions/upload-artifact@v4` and `actions/download-artifact@v4` are not yet compatible with GHES.
