Feb 1, 2025

February 2025 – easybuild-framework: Implemented improved error artifact persistence visibility by explicitly listing individual files copied to permanent storage and updating log messages to show full target paths. This reduces time to locate debugging artifacts in failed builds and strengthens build reliability. Change tracked in commit ea723ddfd9988e97d8749016d26849631448820c. No major bug fixes this month; core focus was observability and reliability improvements.
