## [7.2.0] - 2025-10-21

### BREAKING CHANGES
**Batch Operation Behavior Change:**
- All batch operations now use a consistent "tagged OR selected" logic
- When items are tagged: operations work ONLY on tagged items (selected item is NOT included unless also tagged)
- When NO items are tagged: operations work on the currently selected item only
- This affects: delete, copy, move, symlink, bulk rename, change permissions, change ownership, and open operations
- **Migration**: If you previously relied on operations affecting "tagged + selected", you must now explicitly tag the selected item if you want it included

### Why This Change
This change provides consistent, predictable behavior across all batch operations and eliminates confusion about which items will be affected by an operation.

### Added
- Permission modification syntax: Use `+x`, `-w`, `+rw`, etc. to add/remove permissions incrementally
- Undo support for permission changes (C-P)
- Undo support for ownership changes (C-O)
- Persistent selection: After delete/move operations, the previously selected item remains selected if it still exists

### Improved
- Bulk rename now works on single selected item when no items are tagged (consistent with other operations)

## [7.1.4] - 2025-10-21

### Fixed
- Terminal resizing now works properly in window managers like i3-wm
- Added error handling to WINCH signal handler to prevent crashes on resize
- Manual refresh ('r' key) now re-reads and applies new terminal size
- Terminal size validation prevents invalid dimensions from being applied

## [7.1.3] - 2025-10-21

### Fixed
- Permission change (C-P) now properly updates file colors in the display by invalidating the directory cache
- Broken symlinks can now be deleted or moved to trash without errors

## [7.1.2] - 2025-10-19

### Fixed
- Text file preview now works for all text-encoded files using `file` command MIME type detection

## [7.1.1] - 2025-10-18

### Fixed
- 'A' key toggle_long now properly shows ls -l format
- Cache invalidation when toggling long file info display

## [7.1.0] - 2025-10-17

### Added
- Compressed archive viewer support for .zip, .tar, .gz, .bz2, .xz, .rar, and .7z files
