February 2025 - mozilla/sccache: Stability and robustness improvements to the LRU Disk Cache during removal. Fixed a panic when removing a non-existent file during cache cleanup by handling NotFound gracefully and logging at debug level. This reduces cleanup failures and improves cache reliability in production.
