Add a setting that relaxes the SSRF guard so extensions and built-in network code can reach private/local/loopback targets, for users routing traffic through a local proxy or custom DNS. Disabled by default. Wired end-to-end: Go backend (SetAllowPrivateNetwork toggles isPrivateIP guard), Android/iOS platform bridge, Dart settings model/provider, and a toggle in Download settings.
Decrypt AC-4 via the FFmpeg mov muxer with a -f mov fallback, then repair the output to a standards-compliant ISO MP4: inject the dac4 config box from the encrypted source, normalize the QuickTime container/sample entry, and write iTunes metadata (incl. cover and lyrics) natively. Codec-keyed and generic, so it applies to any extension that returns AC-4 streams. Wired through PlatformBridge/MainActivity for both SAF and local decrypt paths.
FFmpeg's MP4 muxer drops ISRC and label, so write them as iTunes freeform atoms natively after every M4A embed pass. The metadata screen now reads all edited fields from the file on load (file is the source of truth), fixing edited values reverting to stale cached values after reopening.
- iOS: begin/end UIBackgroundTask while a download queue is active so in-flight downloads survive backgrounding for the limited window iOS allows
- extensions: serialize install/upgrade/remove in the Go manager (mutationMu) and in the Dart store provider to stop concurrent goja VM teardown/reload from hard-crashing the app
- main: add runZonedGuarded + FlutterError/PlatformDispatcher onError so uncaught Dart errors are logged, not fatal
- batch convert sheet: precompute localized title/label before showModalBottomSheet to avoid Localizations lookup via a deactivated context
All search, metadata, and download providers are now exclusively
supplied by extensions. The built-in provider registry that previously
exposed Deezer/Tidal/Qobuz as hardcoded providers is fully removed.
Removed across Go, Dart, Kotlin, and Swift:
- BuiltInProviderSpec class, registry, and all accessor helpers
- SearchProviderAllJSON, GetBuiltInProvidersJSON, ParseProviderURLJSON,
ParseDeezerURLExport Go exports and their platform channel bindings
- Built-in provider items in search dropdown, service picker, and
provider priority UI lists
- provider_ui_utils.dart helper file
Deezer metadata enrichment (ISRC lookup, extended metadata, cover
upgrade) remains fully functional through direct DeezerClient calls
in the download pipeline — these are not part of the provider
registry and are unaffected.
Mark deezer as a retired built-in metadata provider so stale user
priority lists are cleaned up on next launch.
Introduce a service-owned download worker that offloads the full
download-and-finalize pipeline to DownloadService on Android, keeping
downloads alive independently of the Flutter UI process.
Key changes:
- Extract SAF download logic from MainActivity into SafDownloadHandler
- Add NativeDownloadFinalizer for Kotlin-side decryption, format
conversion, metadata embedding, ReplayGain, post-processing, and
history persistence
- Extend DownloadService with native queue management (start, pause,
resume, cancel) using coroutine-based worker with AtomicFile snapshots
- Add Dart-side orchestration: snapshot polling, run-id correlation,
adoption on app restart, and fallback to Dart queue
- Forward embedReplayGain, tidalHighFormat, and postProcessingEnabled
through Go backend DownloadRequest struct
- Add nativeDownloadWorkerEnabled setting with UI toggle
- Make DownloadQueueLookup collections unmodifiable
- Extract home_tab.dart helpers/widgets into home_tab_helpers.dart and home_tab_widgets.dart using Dart part files
- Extract queue_tab.dart helpers/widgets into queue_tab_helpers.dart and queue_tab_widgets.dart using Dart part files
- Extract track_metadata_edit_sheet.dart from track_metadata_screen.dart using Dart part file
- Refactor _FileExistsListenableCache into a standalone class in queue_tab_helpers.dart
- Fix artist_screen.dart: replace unreliable findAncestorStateOfType with GlobalKey for _FetchingProgressDialog progress updates
- DRY platform_bridge.dart: extract common JSON decode patterns into reusable helper methods (_decodeRequiredMapResult, _decodeNullableMapResult, _decodeMapListResult, _decodeStringListResult)
Empty the builtInProviderRegistry now that all built-in providers are
retired. Introduce isRetiredBuiltInDownloadProvider and
isRetiredBuiltInMetadataProvider to classify deezer/qobuz/tidal/spotify
as retired, replacing ad-hoc string checks. Add Dart-side metadata
provider priority reconciliation that replaces retired providers with
extensions declaring replacesBuiltInProviders. Remove getQobuzMetadata
from native bridges and platform_bridge.dart. Update crowdin.yml with
additional locale mappings.
Remove Tidal from built-in provider registry (metadata, search, download,
URL parsing) and delete tidal.go. Introduce extension runtime APIs for
lyrics lookup (getLyricsLRC), ISRC existence check (checkISRCExists), and
ISRC index management (addToISRCIndex). Refactor extension download response
construction into normalizeExtensionDownloadResult/overlayExtensionDownloadMetadata
helpers with AlreadyExists support and ISRC indexing. Switch download mirrors
to DoRequestWithUserAgent for ISP blocking detection. Add 50+ new
localization keys and accessibility labels across all supported locales.
Replace hardcoded Tidal/Qobuz switch/case with builtInProviderSpec registry
pattern. Unify searchTidalAll/searchQobuzAll into searchProviderAll,
getDeezerMetadata/getTidalMetadata/getQobuzMetadata into getProviderMetadata,
and parseDeezerUrl/parseQobuzUrl/parseTidalUrl into parseProviderUrl. Remove
extension-specific getAlbum/Playlist/ArtistWithExtension in favor of generic
getProviderMetadata routing. Extract provider UI helpers into
provider_ui_utils.dart. Preserve track_number fallback for zero-value
TrackNumber in album/playlist track lists.
- Add reference-counted cancel entries to prevent premature cleanup when multiple operations share the same itemID
- Propagate cancellation to DownloadTrack, DownloadWithFallback, DownloadWithExtensionsJSON, extension providers, and ISRC search
- Fetch album artist from MusicBrainz when missing during download and re-enrich
- Make ALBUMARTIST tag nullable to avoid writing artistName as album artist
- Add home feed 'Off' option in extension settings
- Skip deezer in download provider priority sanitization
- Embed DownloadQueueLookup into DownloadQueueState; add updatedForIndices() for O(changed) incremental updates during frequent progress ticks instead of full O(n) rebuild
- downloadQueueLookupProvider now reads pre-computed lookup from state directly
- Replace sync file deletion in DownloadedEmbeddedCoverResolver with unawaited async cleanup to avoid blocking the main thread
- Parse JSON payloads on iOS native side (parseJsonPayload) so event sinks and method channel responses return native objects, avoiding redundant Dart-side JSON decode
- Use .cast<String, dynamic>() instead of Map.from() in _decodeMapResult for zero-copy map handling
Resolve API (api.zarz.moe):
- Refactor songlink.go: Spotify URLs use resolve API, non-Spotify uses SongLink API
- Add SongLink fallback when resolve API fails for Spotify (two-layer resilience)
- Remove dead code: page parser, XOR-obfuscated keys, legacy helpers
Multi-artist tag fix (#288):
- Add RewriteSplitArtistTags() in Go to rewrite ARTIST/ALBUMARTIST as split Vorbis comments
- Wire method channel handler in Android (MainActivity.kt) and iOS (AppDelegate.swift)
- Add PlatformBridge.rewriteSplitArtistTags() in Dart
- Call native FLAC rewriter after FFmpeg embed when split_vorbis mode is active
- Extract deezerTrackArtistDisplay() helper to use Contributors in album/playlist tracks
Code cleanup:
- Remove unused imports, dead code, and redundant comments across Go and Dart
- Fix build: remove stale getQobuzDebugKey() reference in deezer_download.go
Enable strict-casts, strict-inference, and strict-raw-types in
analysis_options.yaml. Add custom_lint with riverpod_lint. Fix all
resulting type warnings with explicit type parameters and safer casts.
Also improves APK update checker to detect device ABIs for correct
variant selection and fixes Deezer artist name parsing edge case.
- Defer extension VM initialization until first use with lockReadyVM() pattern to eliminate TOCTOU races and reduce startup overhead
- Add validateExtensionLoad() to catch JS errors at install time without keeping VM alive
- Teardown VM on extension disable to free resources; re-init lazily on re-enable
- Replace full orphan cleanup with incremental cursor-based pagination across launches
- Batch DB writes (upsertBatch, replaceAll) with transactions for atomicity
- Parse JSON natively on Kotlin side to avoid double-serialization over MethodChannel
- Add identity-based memoization caches for unified items and path match keys in queue tab
- Use ValueListenableBuilder for targeted embedded cover refreshes instead of full setState
- Extract shared widgets (_buildAlbumGridItemCore, _buildFilterButton, _navigateWithUnfocus)
- Use libraryCollectionsProvider selector and MediaQuery.paddingOf for fewer rebuilds
- Simplify supporter chip tiers and localize remaining hardcoded strings
- Add SearchAll() for Tidal and Qobuz in Go backend (tracks, artists, albums)
- Add searchTidalAll/searchQobuzAll platform routing for Android and iOS
- Add Tidal/Qobuz options to search provider dropdown in home tab
- Show (Recommended) label and auto-select service in download picker
- Reduce polling interval from 800ms to 1200ms across download progress, library scan, and Android native stream
- Add dirty-flag caching to Go GetMultiProgress() to skip redundant JSON marshaling
- Replace eager provider initialization with staggered Timer-based warmup (400/900/1600ms)
- Add snapshot-based incremental library scan to avoid large MethodChannel payloads
- Move history stats and grouped album filtering to Riverpod providers for better cache invalidation
- Cap home tab history preview to 48 items with deep equality wrapper to reduce rebuilds
- Throttle foreground service notification updates to 2% progress buckets
- Migrate PageView to PageView.builder with AutomaticKeepAliveClientMixin
- Add comparison table to README
Add set/get/clear store registry URL method channel handlers on Android,
iOS, and Go backend so users can configure a custom extension repository.
Store tab now shows a setup screen when no registry URL is configured,
with a cleaner layout (removed redundant description and helper text)
and visible TextField borders for dark theme.
Minor comment and formatting cleanups across several files.
Parse .cue files in library scanner (Go + SAF) to display individual
tracks instead of one large audio file. Add FFmpeg-based CUE splitting
to extract tracks into separate FLAC files with embedded metadata and
cover art.
- Go: CUE parser, two-pass scan (CUE first, skip referenced audio),
virtual paths (cue#trackNN) for DB UNIQUE constraint, audioDir
override for SAF temp-file scenarios
- Android: SAF scanner recognizes .cue in both full and incremental
scan, copies .cue+audio to temp for Go parsing, unchanged-CUE audio
sibling dedup, parseCueSheet handler resolves SAF audio siblings
- Dart: FFmpegService.splitCueToTracks, CUE split UI in track metadata
screen, persistent output dir for SAF splits with write-back
- CUE virtual path normalization across fileExists/fileStat/deleteFile/
openFile; play/share/open blocked for virtual tracks with guidance to
split first; delete only removes DB entry, not shared .cue file
- iOS: parseCueSheet handler
- Localization: 12 new CUE-related strings

Closes#201
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 getLyricsLRCWithSource to return lyrics with source metadata
- Display lyrics source in track metadata screen
- Improve LRC parsing to preserve background vocal tags
- Add dedicated LyricsProviderPriorityPage for provider configuration
- Add Paxsenix as lyrics proxy partner for Apple Music/QQ Music
- Handle inline timestamps and speaker prefixes in LRC display
- Add Genre/Label/Copyright fields to DownloadResult struct
- buildDownloadSuccessResponse now prefers service result metadata over request
- enrichRequestExtendedMetadata fetches Deezer metadata by ISRC before download
- Flutter sends copyright in download request payload
- History merge preserves existing genre/label/copyright on re-download
- Accurate MP3 duration via Xing/VBRI VBR headers, MPEG2/2.5 bitrate tables
- Accurate Opus/Vorbis duration via last Ogg page granule position
- Bitrate field added to LibraryScanResult, LocalLibraryItem, DB v4 migration
- Lossy formats display format+bitrate instead of fake 16-bit quality
