May 1, 2026

May 2026 monthly summary across Gardener repositories focused on security hardening, reliability improvements, and private-CA support with measurable business value. Delivered opt-in CA propagation from SNI TLS secrets to the dashboard API server, enabling private CAs to trust internal endpoints with minimal user impact. Hardened CI/CD pipelines and workflows (Prow-based cherry-pick, least-privilege permissions, explicit authentication, branch validation) to reduce supply-chain risk and improve maintainability. Improved Docker build stability by removing yarn zero-installs and node-gyp devDependency and by fetching dependencies before network restrictions, lowering CI flakiness. Introduced a PING-based HTTP/2 health check with a read-idle timer to detect and recover from stalled watch sessions. Fixed session destruction logic and reduced duplicate scale-down logs for robust runtime behavior. Produced Dashboard v1.84.0 feature highlights and deprecation notices to guide users and migrations. Fixed CI dummy SHA256 hash validation for Gardener Diki workflows to ensure reliable manual runs. Overall, these changes enhance security posture, reliability, and user trust, while enabling smoother private deployments and clearer migration paths.
