February 2026 monthly summary for zed-industries/zed. Delivered persistent editor folds by file path, enabling folds to survive tab closures and workspace cleanup. Implemented file_folds table keyed by (workspace_id, path), following the existing breakpoints persistence pattern, with a backwards-compatible migration from editor_folds to preserve user data. Added tests and manual QA to ensure folds restore across sessions. This work reduces data loss, improves PKM/note workflows, and enhances session resilience across restarts.

January 2026 performance summary for the zed project (zed-industries/zed). Focused on stability and data integrity of fold persistence under external edits. Delivered a robust fix for fold persistence corruption by introducing content fingerprinting, ensuring folds are restored at correct positions after external file modifications. Implemented migration of folds to new entity IDs post-restore to prevent data loss during workspace cleanup. Accompanied by targeted tests and validation, including unit tests for fingerprint storage/retrieval and manual end-to-end checks. Commit reference e04d044271dd4471f4a71ec4cc25077b02a1e0fa captures the fix and validation notes.
