 ## [UNRELEASED]
 
 - You can now quickly debug a job that uses the CodeQL Action by re-running the job from the GitHub UI and selecting the "Enable debug logging" option. [#1132](https://github.com/github/codeql-action/pull/1132)
+- You can now see diagnostic messages produced by the analysis in the logs of the `analyze` Action by enabling debug mode. To enable debug mode, pass `debug: true` to the `init` Action, or [enable step debug logging](https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/enabling-debug-logging#enabling-step-debug-logging). This feature is available for CodeQL CLI version 2.10.0 and later. [#1133](https://github.com/github/codeql-action/pull/1133)
