 # Changelog
 
+## [3.6.0] - 2026-02-09
+
+### Highlights
+
+- **YouTube Provider (Lossy)**: New download option via Cobalt API for tracks not available on lossless services
+  - Opus 256kbps (recommended) or MP3 320kbps quality options
+  - Full metadata embedding: cover art, title, artist, album, track/disc number, year, ISRC
+  - Lyrics fetching from lrclib.net with embed and external .lrc support
+  - Works as fallback when Tidal/Qobuz/Amazon downloads fail
+- **Edit Metadata**: Edit embedded metadata directly from the Track Metadata screen (FLAC, MP3, Opus)
+  - Editable fields: Title, Artist, Album, Album Artist, Date, Track#, Disc#, Genre, ISRC
+  - Advanced fields: Label, Copyright, Composer, Comment
+  - FLAC: native Go writer, MP3/Opus: FFmpeg-based writer
+  - UI refreshes in-place after save without needing to re-open the screen
+  - iOS and Android support
+
+### Added
+
+- Save Cover Art: download high-quality album art as standalone .jpg from track metadata screen
+- Save Lyrics (.lrc): fetch and save lyrics as standalone .lrc file without downloading the song
+- Re-enrich Metadata: re-embed metadata, cover art, and lyrics into existing audio files without re-downloading (FLAC native, MP3/Opus via FFmpeg)
+- Re-enrich now supports local library items: searches Spotify/Deezer by track name + artist to fetch complete metadata from the internet, then embeds cover art, lyrics, genre, label, and all tags into the file
+- YouTube download provider using Cobalt API with SongLink/Odesli integration for Spotify/Deezer ID → YouTube URL conversion
+- SpotubeDL as fallback Cobalt proxy when primary API fails
+- YouTube video ID detection for YT Music extension compatibility
+- Parallel cover art and lyrics fetching during YouTube download
+- Queue progress now shows "X.X MB" instead of "0%" for streaming downloads where total size is unknown (Cobalt tunnel mode)
+- Full metadata pipeline for YouTube downloads: cover art, lyrics, title, artist, album, track#, disc#, year, ISRC
+
+### Changed
+
+- Removed Tidal HIGH (lossy AAC) quality option - use YouTube provider for lossy downloads instead
+- Simplified download service picker by removing dead lossy format code
+- Removed Amazon from download settings UI (now only used as automatic fallback)
+- Cleaned up dead disabled-chip code in download service selector
+
+### Fixed
+
+- Fixed `error.api.youtube.login` by using YouTube Music URLs instead of regular YouTube URLs for Cobalt requests
+- Fixed SongLink to prioritize `youtubeMusic` platform URL over `youtube` for Cobalt compatibility
+- Fixed YouTube metadata not being overwritten by setting `DisableMetadata: true` in Cobalt requests
+- Fixed ISRC validation in metadata enrichment flow - invalid ISRCs no longer trigger failed Deezer lookups
+- Fixed YouTube metadata enrichment to work like other providers (SongLink Deezer ID extraction, proper metadata embedding)
+- Go metadata parsers now read Composer, Comment, Label, Copyright from FLAC, MP3 (ID3v2.2/v2.3/v2.4), and Opus/OGG files
+- Added proper COMM frame parser for ID3v2 (handles language code + description prefix correctly)
+- Fixed Re-enrich Metadata failing on SAF storage files (`content://` URIs) - Kotlin now copies SAF file to temp, Go processes temp file, then writes back for FLAC or returns temp path for FFmpeg (MP3/Opus)
+- Fixed Save Cover Art and Save Lyrics crashing on SAF-stored download history items - now saves to temp then writes to SAF tree via `createSafFileFromPath`
+- Fixed `_getFileDirectory()` crash when called with `content://` URI by adding SAF guard
+- Fixed `readAudioMetadata` Kotlin handler not handling SAF URIs - now copies to temp for reading
+- Added metadata summary log in Re-enrich flow showing all fields before embedding (title, artist, album, track#, disc#, date, ISRC, genre, label)
+
+---
+
+## [3.5.3] - 2026-02-09
+
+### Added
+
+- CSV import flow now includes a new option: **Skip already downloaded songs** before enqueueing tracks
+- Added regression test suite for cross-script matching behavior in Go backend (`go_backend/matching_test.go`)
+
+### Changed
+
+- CSV import confirmation dialog now supports filtering out tracks already present in download history (matched by Spotify ID and ISRC)
+- CSV import enqueue feedback now reports added/skipped counts when duplicate downloads are skipped
+- Home search now prioritizes **Recent Access** when search field is focused with empty input, even if old search results still exist in memory
+- Search filter/result sections are now hidden while Recent Access mode is active to avoid stale-result overlap
+- Recent Access now shows a localized empty-state message when no recent items are available
+- Normalized collapsing AppBar top inset across iOS/Android so header height/animation stays visually consistent on Apple devices
+- Storage & Cache UX improved: `Clear all cache` now preserves web/runtime cache by default (optional), with explicit warnings/actions for runtime cache resets
+- Local library settings now include a display count for tracks excluded because they already exist in download history
+- Responsive layout tuning applied across key screens to reduce hardcoded-height overflow issues on smaller devices
+
+### Fixed
+
+- Fixed false-positive cross-script matching in Qobuz/Tidal where unrelated titles/artists in different scripts could be incorrectly accepted
+- Cross-script title/artist matching now requires transliteration-aware normalization and strict similarity checks instead of auto-accepting script differences
+- Qobuz metadata fallback no longer scans all results when zero title matches are found; title verification is now required
+- Qobuz metadata final validation now rejects results when title does not match expected track name
+- Fixed Home search regression where Recent Access panel could disappear after previous searches
+- Fixed Local Library card/layout crash caused by `Flex` usage under unbounded height constraints
+- Hardened FFmpeg metadata embedding temp-file naming to prevent rare collisions during parallel downloads/fallback flows (Qobuz → Tidal) that could cause missing embedded metadata
+- Fixed SAF external lyrics naming where some providers saved `.lrc` files as `.lrc.txt`; LRC export now uses neutral MIME to preserve `.lrc` extension
+
+## [3.5.2] - 2026-02-08
+
+### Performance
+
+- Home tab search result sections are now virtualized with `SliverList` (lazy item build) instead of eager `Column` rendering, reducing frame drops on large result sets
+- Home tab now narrows Riverpod subscriptions using field-level `select(...)` for search/provider state to reduce unnecessary full-tab rebuilds
+- Search provider dropdown now watches only required fields (`searchProvider`, `metadataSource`, `extensions`) instead of full provider states
+- Track row rendering in Home search now receives precomputed thumbnail sizing/local-library flags from parent to avoid repeated per-item provider watches
+- Removed thumbnail `debugPrint` calls inside track row `build()` to reduce runtime overhead during scrolling/rebuilds
+- Queue tab root subscription no longer watches full queue item list; it now watches only queue presence (`items.isNotEmpty`) to avoid full Library UI rebuilds on every progress tick
+- Queue download header/list rendering has been isolated into dedicated `Consumer` slivers; header now watches only queue length (`items.length`) while item list watches queue item updates
+- Queue filter/sort computations are now centralized and memoized per filter mode within a build pass (`all`/`albums`/`singles`), reducing repeated list transforms for chip counts and page content
+- Selection bottom bar content is now computed only when selection mode is active, removing hidden-state heavy list preparation
+- File existence checks in queue/library rows now use per-path `ValueNotifier` + `ValueListenableBuilder` updates instead of triggering global `setState`, reducing unnecessary whole-tab repaints
+
+### Changed
+
+- Replaced date range filter with sorting options in Library tab: Latest, Oldest, A-Z, Z-A
+- Sorting applies to all views: unified items, downloaded albums, and local library albums
+- Local library items now use file modification time (`fileModTime`) for sorting instead of scan time, providing more accurate chronological ordering
+- Removed redundant manual "Export Failed Downloads" button from Library UI (auto-export setting in Settings is sufficient)
+- Library filters (quality, format, source) now correctly apply to album tabs and update tab chip counts (All/Albums/Singles)
+
+### Fixed
+
+- Fixed local library scan crashing on Samsung One UI devices due to MediaStore URI mismatch in SAF tree traversal
+- Added MediaStore URI fallback in SAF file reader: when SAF permission is denied for Samsung-returned MediaStore URIs, automatically retries using READ_MEDIA_AUDIO permission
+- Hardened SAF scan with per-directory and per-file error handling: scan now skips problematic files instead of aborting entirely
+- Added visited directory tracking to prevent infinite loops from circular SAF references
+- Fixed metadata enrichment cascading failure after one queued download fails: metadata APIs (Deezer, SongLink, Spotify) now use isolated `metadataTransport` so failed download connections cannot poison metadata requests
+- Added immediate connection cleanup on every download failure path (error response and exception), not only periodic cleanup every N downloads
+- Fixed incremental SAF scan edge case where `lastModified()` failure could misclassify existing files as removed (`removedUris`)
+- Fixed tracks marked "In Library" still showing active download button - download button now shows as completed (checkmark) for local library tracks across all screens (album, playlist, artist, home/search)
+- Fixed FFmpeg M4A-to-FLAC conversion erroneously triggered on already-existing FLAC files when re-downloading duplicates via Tidal
+- Fixed SAF download creating empty artist/album folders when re-downloading duplicate tracks; directory is now only created after confirming the file does not already exist
