Nov 1, 2025

Month 2025-11 summary: Focused on stability and change-management for the openshift-eng/art-tools repository. No new features were released; a critical revert was implemented to restore previous Doozer repository configuration behavior by undoing new-style config changes. This action preserved existing CI/CD workflows and reduced risk of configuration migrations impacting repository management. The month emphasized risk assessment, documentation, and clear decision-making around config handling to support a controlled path for future enhancements.
