Nov 1, 2025November 2025: Completed CI/CD and development environment stabilization for puma/puma, with maintainer updates, dependency pinning/rollback, and dev container improvements to ensure clean builds. Implemented a CI workaround by pinning io-event to 1.14.0 to address a compilation issue in rack-conform CI (subsequently reverted). Enhanced devcontainer start hygiene and build reproducibility via rake clean enhancements and Dockerfile updates, including JRuby support. Updated documentation and policy: removed the Code Climate badge and refreshed the SECURITY.md. Added a maintainer to the project. These efforts improve reliability, developer productivity, and security posture.
