+  - Options: 1, 2, or 3 concurrent downloads
+  - Warning about potential rate limiting from streaming services
+- **Download Progress Tracking**: Real-time progress for BTS manifest downloads from Tidal

+- **History Loss on Debug**: History no longer disappears when sideloading via `flutter run --debug`
+
+### Changed
+- Updated version to 1.1.0
