 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.

 - _Upcoming breaking change_: Add support for using `actions/download-artifact@v4` to programmatically consume CodeQL Action debug artifacts.
-
  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.

 ## 3.25.0 - 15 Apr 2024

 - The deprecated feature for extracting dependencies for a Python analysis has been removed. [#2224](https://github.com/github/codeql-action/pull/2224)
-
  As a result, the following inputs and environment variables are now ignored:
-
  - The `setup-python-dependencies` input to the `init` Action
  - The `CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION` environment variable
-
  We recommend removing any references to these from your workflows. For more information, see the release notes for CodeQL Action v3.23.0 and v2.23.0.
 - Automatically overwrite an existing database if found on the filesystem. [#2229](https://github.com/github/codeql-action/pull/2229)
 - Bump the minimum CodeQL bundle version to 2.12.6. [#2232](https://github.com/github/codeql-action/pull/2232)
