+# Changelog
+
+## [1.1.0] - 2026-01-01
+
+### Added
+- **Parallel Downloads**: Download up to 3 tracks simultaneously (configurable in Settings)
+  - Default: Sequential (1 at a time) for stability
+  - 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
+- **Connection Pooling**: Shared HTTP transport to prevent TCP connection exhaustion during large batch downloads
+- **Connection Cleanup**: Automatic cleanup of idle connections every 50 downloads and at queue end
+- **GitHub & Credits Section**: Added links to SpotiFLAC Mobile and original SpotiFLAC desktop in Settings
+
+### Fixed
+- **Download Progress Bug**: Fixed 0% → 100% jump by adding proper progress tracking for BTS format downloads
+- **TCP Connection Exhaustion**: Fixed slow downloads after ~300 tracks by implementing connection pooling and periodic cleanup
+- **Trailing Space in Names**: Fixed download failures when playlist/album/track names have trailing spaces
+- **History Loss on Debug**: History no longer disappears when sideloading via `flutter run --debug`
+
+### Changed
+- Updated version to 1.1.0
+
+### Technical Details
+- Added `concurrentDownloads` field to `AppSettings` model (default: 1, max: 3)

+- Added `strings.TrimSpace()` to all string fields in `DownloadTrack()` and `DownloadWithFallback()`
+- Added shared `http.Transport` with connection pooling in `httputil.go`
+- Added `CleanupConnections()` export for Flutter to call via method channel
+
+## [1.0.5] - Previous Release
