Summary for 2025-07: Focused effort on ensuring Kubernetes API compatibility in actions/actions-runner-controller by removing deprecated preserveUnknownFields from CRDs and updating YAML CRD definitions. This alignment with Kubernetes API best practices reduces upgrade risk for clusters using newer Kubernetes versions and improves long-term maintainability. Major work centered on a critical bug fix rather than new features, delivering immediate stability benefits and smoother upgrade paths.
