Mar 1, 2026In March 2026, delivered a deprecation-oriented documentation change in the csc-training/summerschool repository to improve clarity for learners and ease upcoming migrations. The team signaled deprecation of the original instructions by renaming the file exercise-instructions.md to exercise-instructions-stale.md, providing a clear historical reference and reducing user confusion. This work emphasizes governance around documentation changes and prepares for future removal of outdated content.
