March 2025 — mitre/heimdall2: Frontend styling and theming refinements focused on CSS variable-driven theming, UI consistency, and safe change management. Implemented theme adjustments and a rollback to restore a previous stylesheet state to prevent unintended changes, reinforcing stability and maintainability across the frontend.

December 2024: Stabilized and modernized the CI pipeline for mitre/saf-training by upgrading GitHub Actions components, implementing artifact lifecycle adjustments, and documenting changes for long-term maintainability. Initial CI upgrades to setup-node v4 and v4-based workflow steps improved reliability and consistency, followed by targeted rollbacks to restore compatibility where needed. Artifact handling was iteratively refined: enabling overwriting in v4 to ensure fresh artifacts during rapid iterations, then reverting to non-overwriting to prevent unintended overwrites and ensure artifact provenance. All changes were accompanied by updated Markdown documentation and Appendix D references to keep external users in sync. The result is a more reliable, transparent, and predictable CI/CD process with clearer artifact handling.
