 # Changelog
 
+## 2026-01-01 - 3.26.0 - feat(workspace)
+add external file change detection, conflict resolution UI, and diff editor
+
+- Watch open files for external changes with debounced file watchers (startWatchingFile/stopWatchingFile/stopAllFileWatchers).
+- Prompt the user when disk changes conflict with unsaved local edits via dees-actionbar (actions: Load from Disk, Save Local, Compare).
+- Introduce dees-workspace-diff-editor component and export it; support comparing and resolving diffs (diff-resolved / diff-closed events).
+- Add setContentExternal in dees-workspace-monaco to update editor content from external sources while optionally preserving cursor, selections and scroll position.
+- Start/stop file watchers when files are opened/closed and integrate diff view and actionbar into the workspace UI for seamless conflict handling.
+
 ## 2026-01-01 - 3.25.0 - feat(dees-actionbar)
 add action bar component and improve workspace package update handling
