December 2025 — Cray-HPE/csm: Delivered Platform Manifest Dependency Compatibility Update to align with metacontroller v4.11.25, ensuring stable deployments and reducing upgrade risk.

November 2025 focused on upgrading the metacontroller in Cray-HPE/container-images to ensure compatibility with the latest features and to strengthen the deployment pipeline. The upgrade to metacontroller v4.11.25 was accompanied by a dedicated Dockerfile and CI/CD workflow tailored to the updated version, with images.mk updated to reflect the new release. Key contributions were tightly scoped to enable a clean upgrade path while preserving production stability, enabling faster releases and easier maintenance for container images across environments. Impact: more reliable metacontroller deployments, streamlined image lifecycle management, and improved traceability from code changes to deployed artifacts. The work is anchored by a single, traceable commit (e379e51b6692409d127707c391314d3cb5ec3d5d) with CASMINST-6462 metadata, ensuring auditability and reuse in future upgrade cycles. Technologies/skills demonstrated: Dockerfile authoring, CI/CD workflow configuration, makefile (images.mk) management, Git version control and changelog traceability, and release lifecycle coordination.
