 ## 4.38.0 - 09 Sept 2026
 
 - On GitHub-hosted runners, the CodeQL Action now deletes unused CodeQL bundles from the toolcache before downloading a different bundle, which frees up disk space for the analysis. We expect to roll this change out to everyone in September. [#4124](https://github.com/github/codeql-action/pull/4124)
