 # Changelog
 
+## [3.3.5] - 2026-02-01
+
+Same as 3.3.1 but fixes crash issues caused by FFmpeg.
+
+### Added
+
+- **Export Failed Downloads**: Export failed downloads to TXT file for easy lookup on other platforms
+- **Auto-Export Setting**: Option to automatically export failed downloads when queue finishes
+
+### Fixed
+
+- **FFmpeg Crash**: Fixed crash issues during M4A to MP3/Opus conversion
+- **Service Selection Ignored**: Fixed bug where selecting Qobuz/Amazon from service picker was ignored and always used Tidal instead
+- **iOS iCloud Drive Permission Error**: Block iCloud Drive folder selection on iOS (Go backend cannot access iCloud due to sandboxing)
+
+### Changed
+
+- **Amazon Fallback Only**: Amazon Music is now grayed out in service picker and can only be used as fallback provider
+
+---
+
+## [3.3.1] - 2026-02-01
+
+### Added
+
+- **Clear All Queue Button**: Cancel all queued downloads with one tap ([#96](https://github.com/zarzet/SpotiFLAC-Mobile/issues/96))
+- **IDHS Fallback**: Fallback link resolver when SongLink fails (rate limited 8 req/min)
+- **Lossy Bitrate Options**: MP3 (320/256/192/128kbps), Opus (128/96/64kbps)
+- **Search Filters**: Filter results by type (Tracks, Artists, Albums, Playlists)
+- **Album/Playlist Search**: Deezer search now includes albums and playlists
+- **New Languages**: Turkish (Kaan, BedirhanGltkn), Japanese (Re*Index.(ot_inc))
+- **Optional All Files Access**: Android 13+ no longer requires full storage access; enable in Settings if needed
+- **Improved VPN Compatibility**: Better HTTP/2 support for users behind VPN or restricted networks
+
+### Changed
+
+- **Amazon Download API**: Switched to AfkarXYZ API
+- **Qobuz Download API**: Added Jumo API as fallback
+- **Search Results**: Reduced artist limit from 5 to 2
+
+### Fixed
+
+- **MP3 Download Error 403**: Fixed 403 Forbidden error when downloading MP3 files ([#108](https://github.com/zarzet/SpotiFLAC-Mobile/issues/108))
+- **Opus Cover Art**: Implemented METADATA_BLOCK_PICTURE for proper cover embedding
+- **Deezer Pagination**: Fixed >25 tracks only showing first 25 ([#112](https://github.com/zarzet/SpotiFLAC-Mobile/issues/112))
+- **Duplicate Embed Lyrics Setting**: Removed from Options page ([#110](https://github.com/zarzet/SpotiFLAC-Mobile/issues/110))
+
+---
+
+## [3.2.1] - 2026-01-22
+
+### Added
+
+- **Artist/Album + Singles Folder Structure**: Singles go inside artist folder (`Artist/Album/`, `Artist/Singles/`)
+- **Embed Lyrics Button**: Manually embed online lyrics into tracks from Track Info screen (preserves synced timestamps)
+- **Pause/Resume Button**: Added pause and resume controls next to "Downloading" header in History screen
+- **Instrumental Detection**: Tracks marked as instrumental on lrclib.net now show "Instrumental track" instead of "Lyrics not available"
+
+### Fixed
+
+- **Lyrics**: Multi-artist tracks now search by primary artist first, then full string
+- **Lyrics**: Metadata tags (`[ti:...]`, `[ar:...]`, `[by:...]`) no longer shown in display
+- **Lyrics**: Embed button now correctly appears for tracks with online lyrics
+- **Lyrics**: Manual embed preserves original timestamps instead of plain text
+- **iOS**: Fixed "File not found" after 3.1.x → 3.2.0 update (container UUID migration)
+- **Home Feed**: Greeting now uses device local time
+- **Deezer**: Track position fallback to index+1 when API returns 0
+- **Localization**: Fixed 16 ICU plural syntax warnings in Spanish & Portuguese
+
+### Performance
+
+- **Home Feed**: Precomputed Quick Picks section flag and reduced per-page allocations; explore state now watched by field to cut rebuilds
+- **Home Recent**: Cached recent-access aggregation and limited list allocations for recent downloads
+- **Settings/Theme/Recent**: Cached SharedPreferences instance to avoid repeated `getInstance()` calls
+- **History/DB**: Batched iOS path migration updates to reduce write overhead
+- **Download Queue**: Reduced polling allocations and avoided double-load scheduling for history
+- **Misc**: Precompiled regex in share intent, update dialog, extensions error parsing, log analysis, and LRC cleanup; faster palette cache hits and log filtering
+
+---
+
 ## [3.2.0] - 2026-01-22
 
 > **Note:** Starting from v3.2.0, changelogs will be concise.
