### Added
11
-
- Empty Trash button to permanently delete all trashed documents at once
13
+
- **Version history panel** (Cmd+Shift+H): slide-in sidebar showing all saved versions with relative timestamps, named versions with star badges, word/cell count diffs, restore with confirmation
14
+
- **IndexedDB local backup**: every save backed up locally, crash recovery falls back to local when server fails, keeps last 3 backups per document with FNV-1a hash verification
15
+
- **Save retry**: 3-attempt exponential backoff (1s, 2s, 4s) on server failure
16
+
- **Save indicator**: colored dot (green=saved, orange=saving, red=error) with pulse animation, Cmd+S to force save
17
+
- **beforeunload protection**: browser warns on unsaved changes, emergency IndexedDB backup
18
+
- **Named versions**: "Name this version" via PUT metadata endpoint
19
+
- **ExcelJS**: replaced SheetJS with ExcelJS for proper cell style extraction (background colors, text colors, fonts)
20
+
- **Empty Trash button**: permanently delete all trashed documents at once
21
+
- **Playwright e2e tests**: 16 tests covering document/sheet lifecycle, import, collaboration
22
+
- **CI test gate**: unit + e2e tests run before build, blocking broken deploys
23
+

+
### Fixed
25
+
- XLSX import crash: missing `ensureSheet`/`renderSheetTabs` parameters
26
+
- Trash toggle: list now renders and displays correctly when expanded
27
+
- Import naming: files use filename (minus extension) as document name
28
+
- Title select-all: clicking title selects all text for easy renaming
12
29
- Auto-versioning: snapshots auto-created every 5 minutes for recovery
13
-
- Save protection: `_hadSnapshot` persists across saves, not just loads
