 # Changelog
 
+## [3.5.1] - 2026-02-08
+
+### Performance
+
+- Removed PaletteService (palette_generator) from all screens for faster navigation and reduced memory usage
+- Album, Playlist, Downloaded Album, Local Album, and Track Metadata screens now use blurred cover art as header background instead of dominant color extraction
+- Removed `palette_generator` dependency
+- App startup now renders immediately (`runApp`) while service initialization runs asynchronously in eager init
+- Main shell provider subscriptions now use field-level `select(...)` to reduce unnecessary rebuilds
+- Settings persistence now uses single-flight + queued save coalescing to avoid redundant disk writes
+- Progress polling cadence adjusted to 800ms for download queue, local library scan progress, and Go log polling
+- Android foreground download service progress updates are throttled (change-based updates + 5s heartbeat)
+- SAF history repair is now batched (`20` items per batch) and capped per launch (`60`) to reduce startup I/O spikes
+- Incremental library scan now builds final item list in-memory instead of reloading from database
+- Local cover images in queue/library use direct `Image.file` with `errorBuilder` instead of `FutureBuilder` existence check
+- CSV parser `_parseLine` rewritten: correct escaped-quote handling, no quote characters in output
+- Removed unused legacy screen files (`home_screen.dart`, `queue_screen.dart`, `settings_screen.dart`, `settings_tab.dart`)
+- Incremental local library scan now merges delta results in-memory and sorts once, avoiding full-state reload churn
+- Queue local cover rendering now uses direct `Image.file` + `errorBuilder` (removed repeated async file-exists checks)
+
+### Added
+
+- Auto-cleanup orphaned downloads on history load (files that no longer exist are automatically removed from history)
+
+### Changed
+
+- Removed legacy screen files that were no longer used after the tab/part refactor:
+  - `lib/screens/home_screen.dart`
+  - `lib/screens/queue_screen.dart`
+  - `lib/screens/settings_screen.dart`
+  - `lib/screens/settings_tab.dart`
+- Concurrent download limit increased from `3` to `5` (settings clamp + Options UI chips now support `1..5`)
+- Download queue now uses a single parallel scheduler path; `1` concurrency is handled as parallel-with-limit-1 (no separate sequential engine)
+- Download queue now listens to settings updates in real-time so concurrency/output settings stay in sync while queue is active
+
+### Fixed
+
+- CSV parser now correctly handles escaped quotes (`""`) inside quoted fields during import
+- Fixed dynamic concurrency update during active downloads: changing limit (e.g. `1 -> 3`) now schedules additional queued items without waiting current active item to finish
+- Queue scheduler now re-checks capacity/queued items on short intervals to avoid blocking on long-running single active download
+
+### Dependencies
+
+#### Flutter
+- `flutter_local_notifications` 19.x → 20.0.0 (breaking: all positional params converted to named params)
+- `connectivity_plus` 6.x → 7.0.0
+- `flutter_secure_storage` 9.x → 10.0.0
+- Removed `palette_generator` dependency
+
+#### Go
+- `go-flac/go-flac` v1.0.0 → v2.0.4
+- `go-flac/flacvorbis` v0.2.0 → v2.0.2
+- `go-flac/flacpicture` v0.3.0 → v2.0.2
+- Go toolchain 1.24 → 1.25.7
+
+#### Android
+- Android Gradle Plugin 8.x → 9.0.0
+- Kotlin 2.1.x → 2.3.10
+- `desugar_jdk_libs` → 2.1.5
+- `kotlinx-coroutines-android` → 1.10.2
+- `lifecycle-runtime-ktx` → 2.10.0
+- `activity-ktx` → 1.12.3
+
+#### CI/CD
+- `actions/cache` v4 → v5
+- `actions/checkout` v4 → v6
+- `actions/setup-go` v5 → v6
+- `actions/setup-java` v4 → v5
+- `softprops/action-gh-release` v1 → v2
+- GitHub artifact actions updated
