 - The CodeQL Action now downloads bundles compressed using Zstandard on GitHub Enterprise Server when using Linux or macOS runners. This speeds up the installation of the CodeQL tools. This feature is already available to GitHub.com users. [#2573](https://github.com/github/codeql-action/pull/2573)

 - _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 to `actions/download-artifact@v3` to `actions/download-artifact@v4` will begin failing then.
