March 2025 highlights focused on strengthening CI/CD security, improving release reliability, and stabilizing tests across four Kyma projects. Implemented least-privilege permissions, enabled OIDC token-based authentication for release workflows, and refined PR event handling to reduce risk and improve pipeline reliability. Also pinned envtest to ensure stable integration tests. These changes reduce attack surface, enhance automation security, and support more reliable deployments across modulectl, runtime-watcher, template-operator, and lifecycle-manager.
