+## [1.1.0] - 2026-01-01
+
+### Added
+- **Parallel Downloads**: Download up to 3 tracks simultaneously (configurable in Settings)

+  - 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 Persistence**: Download history now persists across app restarts using SharedPreferences
