Version rolled back from v4.x to v3.7.0. After extensive work on v4's
internal streaming engine, smart queue, DASH pipeline, and media controls,
we realized v3 was already feature-complete. Adding more big features
only made maintenance increasingly difficult and the developer's life
miserable. Stripped back to what works: external player only, cleaner
codebase, sustainable long-term.
- Remove just_audio, audio_service, audio_session and entire internal
playback engine (smart queue, notification, shuffle/repeat, prefetch)
- Remove PlaybackItem model, MiniPlayerBar widget, notification drawables
- Remove playerMode setting (external-only now)
- Migrate MainActivity from AudioServiceFragmentActivity to
FlutterFragmentActivity
- Migrate Qobuz to MusicDL API
- Update changelog with v3.7.0 rollback explanation
- Add configurable SongLink region (userCountry) setting with picker UI
- Pass songLinkRegion through download request payload to Go backend
- Go backend: thread-safe global SongLink region with per-request override
- Fix downloaded track not recognized in collection tap: add findByTrackAndArtist
fallback in download history lookup chain (Spotify ID → ISRC → name+artist)
- Apply same name+artist fallback to isDownloaded check in track options sheet
- Add missing library_database.dart import for LocalLibraryItem
- Add multi-select support to library_tracks_folder_screen (wishlist, loved,
playlist) with long-press to enter selection mode, animated bottom bar with
batch remove/download/add-to-playlist actions, and PopScope exit handling
- Create batch showAddTracksToPlaylistSheet in playlist_picker_sheet with
playlist thumbnail widget and cover image support
- Add playlist grid selection tint overlay in queue_tab
- Optimize collection lookups with pre-built _allPlaylistTrackKeys index and
isTrackInAnyPlaylist/hasPlaylistTracks accessors
- Eagerly initialize localLibraryProvider and libraryCollectionsProvider
- Enable SQLite WAL mode and PRAGMA synchronous=NORMAL across all databases
- Go backend: duplicate SAF output FDs before provider attempts to prevent
fdsan abort on fallback retries; close detached FDs after download completes
- Go backend: rewrite compatibilityTransport to try HTTPS first and only
fallback to HTTP on transport-level failures, preventing redirect loops
- Go backend: enforce HTTPS-only for extension sandbox HTTP clients
- Replace SharedPreferences with SQLite (AppStateDatabase, LibraryCollectionsDatabase) for download queue, library collections, and recent access history
- Add Set-based O(1) track containment checks for wishlist, loved, and playlist tracks
- Add batch addTracksToPlaylist with PlaylistAddBatchResult
- Go backend: strict mode locks download to selected provider when auto fallback is off
- Go backend: fix extension progress normalization (percent/100) and lifecycle tracking
- Go backend: case-insensitive provider ID matching throughout fallback chain
- Lyrics embedding now respects lyricsMode setting (embed/both/off)
- Debounced queue persistence to reduce write frequency
- Fix shouldUseFallback logic to not be gated by useExtensions
