 # Changelog

+## [3.5.0] - 2026-02-07
+
+### Highlights
+
+- **SAF Storage (Android 10+)**: Proper Storage Access Framework support for download destination (content URIs)
+  - Select download folder via SAF tree picker
+  - Downloads now write to SAF file descriptors (`/proc/self/fd/*`) instead of raw filesystem paths
+  - Works around Android 10+ scoped storage permission errors
+- **Modern Onboarding Experience**: Completely redesigned Setup and Tutorial screens
+
+### Added
+
+- Home feed disk caching via SharedPreferences for instant restore on app startup
+- SAF display path resolver in native Android layer (converts tree URIs to readable paths)
+- New settings fields for storage mode + SAF tree URI
+- SAF platform bridge methods: pick tree, stat/exists/delete, open content URI, copy to temp, write back to SAF
+- SAF library scan mode (DocumentFile traversal + metadata read)
+- Incremental library scanning for filesystem and SAF paths (only scans new/modified files and detects removed files)
+- Force Full Scan action in Library Settings to rescan all files on demand
+- Downloaded files are now excluded from Local Library scan results to prevent duplicate entries
+- Legacy library rows now support `file_mod_time` backfill before incremental scans (faster follow-up scans after upgrade)
+- Library UI toggle to show SAF-repaired history items
+- Scan cancelled banner + retry action for library scans
+- Android DocumentFile dependency for SAF operations
+- Post-processing API v2 (SAF-aware, ready to replace v1)
+- Donate page in Settings with Ko-fi and Buy Me a Coffee links
+- Per-App Language support on Android 13+ (locale_config.xml)
+- Interactive tutorial with working search bar simulation and clickable download buttons
+- Tutorial completion state is persisted after onboarding
+- Visual feedback animations for page transitions, entrance effects, and feature lists
+- New dedicated welcome step in setup wizard with improved branding
+
+### Changed
+
+- Download pipeline supports `output_path` + `output_ext` for Go backend
+- Tidal/Qobuz/Amazon/Extension downloads use SAF-aware output when enabled
+- Post-processing hooks run for SAF content URIs (via temp file bridge)
+- File operations in Library/Queue/Track screens now SAF-aware (`open`, `exists`, `delete`, `stat`)
+- Local Library scan defaults to incremental mode; full rescan is available via Force Full Scan
+- Local library database upgraded to schema v3 with `file_mod_time` tracking for incremental scan cache
+- Platform channels expanded with incremental scan APIs (`scanLibraryFolderIncremental`) on Android and iOS
+- Android platform channel adds `getSafFileModTimes` for SAF legacy cache backfill
+- Android build tooling upgraded to Gradle 9.3.1 (wrapper)
+- Android build path validated with Java 25 (Gradle/Kotlin/assemble debug)
+- SAF tree picker flow in `MainActivity` migrated to Activity Result API (`registerForActivityResult`)
+- `MainActivity` host migrated to `FlutterFragmentActivity` for SAF picker compatibility
+- Legacy `startActivityForResult` / `onActivityResult` SAF picker path removed
+- Setup screen UI polish: smaller logo, thin outline borders on text fields
+- Removed support section from About page (moved to Donate page)
+- Qobuz squid.wtf region fallback for blocked regions
+- Setup screen converted to PageView flow with animated progress bar and modern card layouts
+- Tutorial screen aligned with Setup Screen design, updated typography and softened UI shapes
+- Larger, more accessible navigation buttons for onboarding flow
+- Reduced visual noise by removing unnecessary glow effects
+
+### Fixed
+
+- Android 10+ `permission denied` when writing to `/storage/emulated/0` (now handled via SAF)
+- SAF history repair: auto-resolve missing content URIs using tree + filename
+- SAF download fallback: retry in app-private storage when SAF write fails
+- Tidal DASH manifest writing when output path is a file descriptor (no invalid `.m4a` path)
+- External LRC output in SAF mode
+- Restored old-device renderer fallback while using `FlutterFragmentActivity` by injecting shell args from a custom `FlutterFragment` (`--enable-impeller=false` on problematic devices)
+- Preserved Flutter fragment creation behavior (cached engine, engine group, new engine) while adding Impeller fallback support
+- SAF tree picker result now consistently returns `tree_uri` payload with persisted URI permission handling
+- SAF share file now copies to temp before sharing (fixes share from SAF content URI)
+- Home feed not updating after installing extension with homeFeed capability (no longer requires app restart)
+- Library scan hero card showing 0 tracks during scan (now shows scanned file count in real-time)
+- Library folder picker no longer requires MANAGE_EXTERNAL_STORAGE on Android 10+ (uses SAF tree picker)
+- One-time SAF migration prompt for users updating from pre-SAF versions
+- Fixed `fileModTime` propagation across Go/Android/Dart so incremental scan cache is stored and reused correctly
+- Fixed SAF incremental scan key mismatch (`lastModified` vs `fileModTime`) and normalized result fields (`skippedCount`, `totalFiles`)
+- Fixed incremental scan progress when all files are skipped (`scanned_files` now reaches total files)
+- Removed duplicate `"removeExtension"` branch in Android method channel handler (eliminates Kotlin duplicate-branch warning)
+
+---
+
+## [3.4.2] - 2026-02-04
+
+### Improved
+
+- **Mobile Network Reliability**: All providers (Qobuz, Tidal, Amazon, Deezer) now have retry logic with exponential backoff
+  - Increased API timeouts: 15s → 25s (Deezer, Qobuz, Tidal), 30s (Amazon)
+  - Up to 3 retry attempts per API call (500ms → 1s → 2s backoff)
+  - Retryable: timeout, connection reset/refused, EOF, HTTP 5xx, HTTP 429
+- **SongLink ID Extraction**: Extract QobuzID/TidalID directly from SongLink URLs
+  - New fields in `TrackAvailability`: `QobuzID`, `TidalID`
+  - Qobuz/Tidal now use direct Track ID from SongLink instead of re-parsing URLs
+- **Qobuz Download Flow**: New Strategy 3 - get QobuzID from SongLink before ISRC search
+  - Cache hit now uses `GetTrackByID()` directly instead of searching again
+  - Pre-warm cache tries SongLink first before direct ISRC search
+- **Tidal Download Flow**: Use `availability.TidalID` directly from SongLink struct
+
+---
+
+## [3.4.1] - 2026-02-04
+
+### Fixed
+
+- Metadata Priority order now persists after app restart
+- Download Provider Priority order now persists after app restart
