Jun 1, 2025June 2025: Fixed repository hygiene for CourseMapper-webserver by correcting the uploads .gitignore exclusion. Updated path from 'public/uploads' to '/webserver/public/uploads' to ensure generated assets are not tracked. This change reduces repo size, prevents accidental commits of assets, and improves deployment consistency.

Apr 1, 2025April 2025: Key CI/CD improvements for the ude-soco/CourseMapper-webserver project. Stabilized the CI workflow against a regression in action-contains-tag, added Git configuration to prevent remote HEAD tracking issues, and relaxed release gating to allow tagged releases across branches. These changes reduce release friction and improve pipeline reliability, enabling safer cross-branch deployments and faster time-to-production for feature releases.
