 Note that the only difference between `v2` and `v3` of the CodeQL Action is the node version they support, with `v3` running on node 20 while we continue to release `v2` to support running on node 16. For example `3.22.11` was the first `v3` release and is functionally identical to `2.22.11`. This approach ensures an easy way to track exactly which features are included in different versions, indicated by the minor and patch version numbers.

 - We are rolling out a feature in January 2024 that will disable Python dependency installation by default for all users. This improves the speed of analysis while having only a very minor impact on results. You can override this behavior by setting `CODEQL_ACTION_DISABLE_PYTHON_DEPENDENCY_INSTALLATION=false` in your workflow, however we plan to remove this ability in future versions of the CodeQL Action. [#2031](https://github.com/github/codeql-action/pull/2031)
 - The CodeQL Action now requires CodeQL version 2.11.6 or later. For more information, see [the corresponding changelog entry for CodeQL Action version 2.22.7](#2227---16-nov-2023). [#2009](https://github.com/github/codeql-action/pull/2009)
