 # Changelog

-## [3.5.0-beta.1] - 2026-02-06
+## [3.6.7] - 2026-02-13
+
+### Added
+
+- "Advanced Filename Templates" - new placeholders for custom track/disc formatting and date patterns
+  - `{track_raw}` and `{disc_raw}` - unpadded raw numbers
+  - `{track:N}` and `{disc:N}` - zero-padded to N digits (e.g. `{track:02}` → `01`)
+  - `{date}` - full release date from metadata
+  - `{date:%Y-%m-%d}` - date formatting with strftime patterns
+  - "Show advanced tags" toggle in Settings > Download > Filename Format to reveal these placeholders
+- Low-RAM / ARM32-only device profiling - detects constrained devices at startup and reduces image cache (120 items / 24 MiB) and disables overscroll effects for smoother performance
+- Responsive selection bar on artist screen - switches to compact stacked layout on narrow screens (< 430dp) or large text scale (> 1.15x)
+- Quality picker dialog before downloading individual tracks from artist screen (when "Ask quality before download" is enabled)
+- Project website with GitHub Pages deployment workflow
+  - Mobile burger menu navigation for all site pages
+- Go filename template test suite
+
+### Fixed
+
+- Fixed ICU plural syntax errors in DE, ES, PT, RU translations - incorrect `=1` clause was causing missing plural forms
+- Fixed featured-artist regex incorrectly splitting on `&` character (e.g. "Simon & Garfunkel" was being split) - removed `&` from separator pattern
+- Fixed `{date}` placeholder not working in filename templates - release date was not being passed to the template builder across all providers (Amazon, Qobuz, Tidal, YouTube, extensions)
+
+### Changed
+
+- Improved Go backend metadata handling - filename builder now supports fallback metadata keys and automatic type conversion for more robust template rendering
+- Extension providers now pass full metadata set to filename builder (track, disc, year, date, release_date)
+- Updated translations: added filename advanced tags strings (EN, ID), regenerated all locale dart files
+- Updated app screenshot assets
+
+---
+
+## [3.6.6] - 2026-02-12
+
+### Added
+
+- "Filter Contributing Artists in Album Artist" setting - strips featured/contributing artists from Album Artist metadata tag
+- Library scan notifications (Android and iOS) - shows progress, completion, failure, and cancellation status
+- Collapsible "Artist Name Filters" section in download settings UI
+
+### Fixed
+
+- Fixed downloads not working on iOS - missing `downloadByStrategy` and `downloadFromYouTube` method channel handlers in AppDelegate.swift
+- Fixed extended metadata (genre, label, copyright) lost during service fallback (e.g. Tidal unavailable, falls back to Qobuz) - Go backend now enriches metadata from Deezer by ISRC before download and preserves it through the fallback chain
+- Fixed local library showing incorrect "16-bit" quality label for lossy formats (MP3, Opus) - now displays actual bitrate (e.g. "MP3 320kbps")
+- Fixed inaccurate Opus/Vorbis duration calculation (e.g. 4:11 showing as 8:44) - now reads granule position from last Ogg page for precise duration
+- Fixed MP3 duration/bitrate inaccuracy for VBR files - added Xing/Info and VBRI header parsing with MPEG2/2.5 bitrate table support
+- Fixed Track Metadata screen showing scan date instead of file date for local library items
+- Fixed SAF content URI paths displayed as raw `content://` strings in Track Metadata - now shows human-readable paths
+
+### Changed
+
+- Removed legacy iOS download handlers (`downloadTrack`, `downloadWithFallback`, `downloadFromYouTube`) - iOS now uses `downloadByStrategy` only
+- Updated translations from Crowdin (all 14 languages)
+
+---
+
+## [3.6.5] - 2026-02-10

 ### Highlights
+
+- **Audio Format Conversion**: Convert between FLAC, MP3, and Opus directly from Track Metadata screen with full metadata and cover art preservation
+- **PC v7.0.8 Backend Merge**: Adopts several Go backend improvements from SpotiFLAC PC v7.0.8 including Amazon encrypted stream support, SpotFetch metadata fallback, and Qobuz API update
+- **Amazon Music Re-enabled**: Amazon provider back in service with new API
+
+### Added
+
+- "Use Primary Artist Only" setting: strips featured artists from folder names (e.g. "Justin Bieber, Quavo" becomes "Justin Bieber") for cleaner folder organization
+  - Supports separators: `, ` `;` `&` `feat.` `ft.` `featuring` `with` `x`
+  - Available in Settings > Download > below "Use Album Artist for folders"
+- Audio format conversion from Track Metadata screen
+  - Convert between FLAC, MP3, and Opus formats (any direction)
+  - Selectable bitrate: 128k, 192k, 256k, 320k
+  - Full metadata and cover art preservation during conversion
+  - Confirmation dialog before converting (original file deleted after)
+  - SAF storage support: copies to temp, converts, writes back via SAF
+  - Download history automatically updated with new file path
+- Unified download request contract (`DownloadRequestPayload`) for all providers/flows
+  - Includes full superset fields: lyrics mode, genre/label/copyright, provider IDs, SAF params, cover/quality settings
+  - Added strategy flags in payload: `use_extensions`, `use_fallback`
+- New Go unified router entrypoint: `DownloadByStrategy(requestJSON)`
+  - Routing priority: YouTube service -> extension fallback -> built-in fallback -> direct service
+- New Android method channel handler: `"downloadByStrategy"` -> `Gobackend.downloadByStrategy(...)`
+- SpotFetch metadata fallback integration for Spotify-blocked regions
+  - New backend client for `spotify.afkarxyz.fun/api`
+  - Automatic fallback in Spotify metadata fetch path when primary source fails
+- Lyrics extraction now supports MP3 (ID3v2) and Opus/OGG (Vorbis comments) in addition to FLAC
+  - Includes heuristic detection of lyrics stored in Comment fields
+- Edit Metadata now supports manual cover selection (pick/replace cover image) and embeds it into audio tags on save
+- Save Lyrics now shows an immediate in-progress snackbar (`Saving lyrics...`) so users know the operation has started
+
+### Changed
+
+- Merged several Go backend improvements from SpotiFLAC PC v7.0.8: Amazon new API with encrypted stream/decryption support, SpotFetch metadata fallback for Spotify-blocked regions, multi-format lyrics extraction (MP3/Opus/OGG), Qobuz Jumo API update.
+- Download queue execution now builds one payload and uses a single bridge entrypoint (`PlatformBridge.downloadByStrategy`) instead of branching into multiple bridge methods
+- Dart `downloadByStrategy` now sends a single request to Go (`downloadByStrategy` channel); routing concern is centralized in Go backend
+- Legacy Dart bridge methods (`downloadTrack`, `downloadWithFallback`, `downloadWithExtensions`, `downloadFromYouTube`) are now thin wrappers and marked `@Deprecated`
+- Qobuz downloader updated to latest Jumo API contract (`/get` endpoint, required headers)
+- Amazon download flow now returns `decryption_key` from Go and performs decryption in Flutter (local file + SAF paths)
+- Amazon now uses the new `amazon.afkarxyz.fun` API flow (ASIN-based track endpoint + legacy fallback) with encrypted stream support
+- Amazon ASIN extraction rewritten with robust URL/query-param parsing and regex fallback
+- Amazon provider re-enabled in download service picker and download settings (alongside Tidal, Qobuz, and YouTube picker flow)
+- Track Metadata cover UI now refreshes from the embedded file after Edit Metadata/Re-enrich, so the displayed art matches actual file tags
+- Edit Metadata cover section moved to the top of the form and now previews current embedded cover before replacement (plus selected replacement preview)
+- Edit Metadata cover preview enlarged (120px to 160px) with shadow, side-by-side layout for current vs selected cover, and label repositioned below image
+
+### Fixed
+
+- Fixed lyrics mode "External .LRC" still embedding lyrics into metadata - `lyrics_mode` was not being sent to Go backend for single-service downloads and YouTube provider, causing Go to default to "embed"
+- Fixed `flutter_local_notifications` v20 breaking changes - migrated all `initialize()`, `show()`, and `cancel()` calls from positional parameters to named parameters
+- Fixed SAF duplicate folder bug: concurrent batch downloads creating empty folders with `(1)`, `(2)`, `(3)` suffixes - added synchronized lock to `ensureDocumentDir` in Kotlin with duplicate detection and cleanup
+- Track Metadata lyrics section now hides "Embed Lyrics" when lyrics are already embedded in file, preventing redundant embed attempts
+- Fixed lyrics embed path to support FLAC/MP3/Opus consistently (including SAF files) without forcing unsupported parser paths
+- Inconsistent parameter parity across download paths
+  - `downloadWithExtensions` now carries `copyright`
+  - YouTube path now carries `embed_max_quality_cover` and metadata parity fields
+- Inconsistent success response metadata between direct/fallback flows
+  - Added shared Go response builder for `DownloadTrack` and `DownloadWithFallback`
+  - Success responses now consistently include `genre`, `label`, `copyright`, and `lyrics_lrc`
+- YouTube success response now also includes extended metadata fields (`cover_url`, `genre`, `label`, `copyright`) for parity with other providers
+- Fixed `Save Lyrics` crash on Android (`java.lang.Integer cannot be cast to java.lang.Long`) by normalizing `duration_ms` channel argument as `Number -> Long`
+- Fixed FLAC Re-enrich cover edge case where metadata could be written without cover when temp cover file creation failed; FLAC cover embed now uses in-memory bytes and verifies cover after write
+- Fixed FLAC picture-block embed robustness by detecting image MIME via magic bytes (JPEG/PNG/GIF/WEBP) instead of relying on filename extension
+- Fixed MP3/Opus metadata rewrite flows to preserve existing embedded cover when no new cover is available
+- Fixed Library tab cover not updating after manual cover edit/re-embed for downloaded tracks
+  - Queue/Library now prefers embedded cover art extracted from local files (not just cached `coverUrl`)
+  - Added per-track extraction cache with file-modification invalidation so updated embedded art is reflected in Library
+  - Extraction is now on-demand for edited tracks only (not full-library reload)
+  - Returning from Track Metadata now refreshes cover cache only for the affected track
+  - Cover refresh is now skipped when file modification time is unchanged, removing unnecessary flash when simply opening/closing metadata screen
+- Fixed repeated cover preview extraction in Track Metadata screen (`track_cover_preview_*`) causing visible flash when reopening
+  - Added in-memory preview cache keyed by file path so reopening metadata reuses existing preview without re-extract
+  - Cache validation uses file modification time for filesystem paths; SAF paths are refreshed only after successful edit actions
+  - Queue/Library now also compares SAF file last-modified (`getSafFileModTimes`) before refreshing embedded-cover cache
+  - Preview cache key is now stable per track item (not volatile temp SAF path), eliminating false cache misses on SAF-backed files
+  - Track Metadata no longer auto-extracts cover preview on every screen open; extraction now runs only after actual edit/re-enrich changes (or when explicitly forced)
+- Track metadata edits/re-enrich now sync updated tags back into `downloadHistoryProvider` + SQLite history rows
+  - Non-Library screens that read download history (Home/album/history views) now reflect updated title/artist/album/tags without manual rescan
+  - Track Metadata back-navigation now returns an explicit update result after successful edits/re-enrich, enabling History-tab cover refresh fallback when SAF timestamps are unreliable
+
+### Performance
+
+- Configured Flutter image cache limits (240 entries / 60 MiB) and added `ResizeImage` wrappers for cover art precaching across all screens, reducing peak memory usage on cover-heavy pages
+- Added LRU eviction to Deezer cache with configurable max entries per cache type (search/album/artist/ISRC) and periodic expired-entry cleanup to prevent unbounded memory growth in long sessions
+- Download progress notifications are now normalized (2-decimal progress, 1-decimal speed, 0.1 MiB byte steps) and deduplicated by track/artist/percent/queue-count, reducing notification overhead during batch downloads
+- Each queue item now uses a dedicated `ConsumerWidget` with per-item `.select()` instead of rebuilding the entire list on any item change; items are wrapped in `RepaintBoundary` for paint isolation
+- Queue/Library search indexes are now built on-demand per item instead of upfront for all items, with bounded LRU caches (max 4000 entries)
+- `copyWith` now preserves derived lookup indexes (ISRC map, track key set) when items list is unchanged, avoiding O(n) rebuild on every scan progress update
+- Scan progress polling now compares values before calling `setState`, skipping unnecessary widget rebuilds when nothing changed
+- Added in-flight flag to download progress and library scan polling to prevent concurrent timer callbacks from overlapping
+- New `DownloadedEmbeddedCoverResolver` service replaces per-screen cover extraction logic with a shared bounded cache (160 entries), mod-time validation, and throttled refresh checks
+- Multiple embedded cover change callbacks are now coalesced into a single frame via `addPostFrameCallback`, preventing redundant rebuilds
+- Downloaded album screen now caches filtered/sorted track lists and reuses them when the source data reference is unchanged
+- Home tab recent downloads now use single-pass aggregation instead of building full per-album lists, and store only IDs instead of full item objects for the clear-all action
+- Removed duplicate `_downloadedSpotifyIds` Set and `_isrcSet` (both now use existing map lookups), removed unused `_isTyping` state in home tab
+- Track cache pre-warming is now capped at 80 tracks per request to avoid excessive backend calls on large playlists
+- About page contributor avatars now use `memCacheWidth`/`memCacheHeight` to decode at display size instead of full resolution
+- Orphaned download cleanup now checks file existence in parallel (chunk 16) instead of sequentially
+- Local library `findByTrackAndArtist` now uses O(1) map lookup (`_byTrackKey`) instead of O(n) linear scan
+- Local library database load and SharedPreferences fetch now run in parallel
+- Legacy mod-time backfill now uses chunked parallel `File.stat` (chunk 24) with per-chunk cancel check
+- Downloaded album screen now caches disc grouping, sorted disc numbers, common quality, and embedded cover path with reference-identity invalidation
+- Local album screen common quality is now computed once during cache rebuild instead of per-build
+- Batch delete in album screens now uses O(1) map lookup (`tracksById`) instead of `.where().firstOrNull`
+- Cache management page now fires all async init calls in parallel and uses chunked async directory deletion (chunk 24)
+- Cover resolver preview file existence check is now throttled (2.2s interval) to reduce synchronous I/O in build path
+- History and library database DELETE operations are now chunked (500 per batch) to stay within SQLite variable limits
+- Library database `cleanupMissingFiles` now checks file existence in parallel (chunk 16) and deletes in batched SQL
+
+### Security
+
+- All logs (Go and Dart) now automatically redact Bearer tokens, access/refresh tokens, client secrets, API keys, and passwords using regex-based sanitization before storage
+- Extension auth URLs are now validated for HTTPS-only, no embedded credentials, and no private/local network targets before opening
+- Auth URLs in logs are summarized to scheme+host+path only (query params stripped) to prevent token leakage; token exchange error bodies are truncated and sanitized
+- Extension HTTP requests now block URLs with embedded credentials (`user:pass@host`)
+- Extension storage files changed from `0644` to `0600` (owner-only read/write)
+- All SAF relative directory paths are now sanitized per-segment with `.`/`..` filtering; all user-provided file names pass through `sanitizeFilename()` before use
+- Extension ID is sanitized before building download destination path
+- Log export device info now shows Build ID and Security Patch level instead of masked Device ID
+
+### Technical
+
+- Centralized request serialization in `PlatformBridge` via shared invoke helper and unified payload model
+- Go strategy router normalizes incoming service casing before dispatch
+- Extension runtime: `customSearch` now passes query/options via VM globals instead of string interpolation, preventing parser edge cases on certain devices
+- Extension runtime: JS panic handler now logs full stack trace for easier debugging
+- `DownloadQueueLookup` expanded with `byItemId` map and `itemIds` list for O(1) queue item access from UI
+- Non-error/non-fatal log entries are now skipped entirely (not just hidden) when detailed logging is disabled, reducing buffer growth and Go log polling overhead
+
+### Removed
+
+- Buy Me a Coffee references removed from donate page, FUNDING.yml, README, and all localization files (account suspended)
+
+---
+
+## [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
+
+## [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
