- Tidal: use actual API track_number/disc_number when request values are 0
(fixes search/popular downloads having no track position in metadata)
- Extension enrichment: copy TrackNumber/DiscNumber back from enriched results
- Extension fallback download: add request metadata fallback for non-source
extensions (Album, AlbumArtist, ReleaseDate, ISRC, TrackNumber, DiscNumber)
- FFmpeg: add -v error -hide_banner to all commands (embed, convert, CUE split)
to eliminate banner, build config, and full metadata/lyrics dump in logcat
- ebur128: add framelog=quiet to suppress per-frame loudness measurements
while keeping the summary needed for ReplayGain parsing
- Track metadata screen: separate embedded lyrics check from online fetch,
show file-only state with manual online fetch button
ReplayGain (track + album):
- Scan track loudness via FFmpeg ebur128 filter (-18 LUFS reference)
- Duration-weighted power-mean for album gain computation
- Support for FLAC (native Vorbis), MP3 (ID3v2 TXXX), Opus, M4A
- Album RG auto-finalizes when all album tracks complete
- Retryable gate: blocks finalization while failed/skipped items exist
- SAF support: lossy album RG writes via temp file + writeTempToSaf
- New embedReplayGain setting (off by default) with UI toggle
APEv2 tag support:
- Full APEv2 reader/writer with header+items+footer format
- Merge-based editing with override keys for explicit deletions
- Binary cover art embedding (Cover Art (Front) item)
- Library scanner support for .ape/.wv/.mpc files
- ReplayGain fields in APE read/write/edit pipeline
Bug fixes (26):
- setArtistComments wiping fields on empty string value
- APEv2 rewrite corrupting files with ID3v1 trailer
- APE edit replacing entire tag instead of merging
- ReplayGain lost on manual MP3/Opus/M4A metadata edit
- Editor metadata save losing custom tags (preserveMetadata)
- Album RG accumulator not cleaned on queue mutation
- Album gain using unweighted mean instead of power-mean
- writeAlbumReplayGainTags return value silently ignored
- SAF album RG writing to deleted temp path
- Cancelled tracks polluting album gain computation
- APE ReplayGain not wired end-to-end
- APE field deletion not working in merge
- APE cover edit was a no-op
- Album RG duplicate entries on retry
- APE apeKeysFromFields missing track/disc/lyrics mappings
- Album RG entries purged by removeItem before computation
- FFmpeg converters discarding empty metadata values
- _appendVorbisArtistEntries skipping empty value (null vs empty)
- Album RG write-back fails for SAF lossy files
- Album RG partial finalization on failed tracks
- FLAC ClearEmpty flag destroying tags on partial callers
- clearCompleted not retriggering album RG checks
- ReadFileMetadata MP3/Ogg missing label and copyright
- Cover embed on CUE split destroying split artist tags
- Album RG gain format inconsistent (missing + prefix)
- FLAC reader/editor missing tag aliases (ALBUMARTIST, LABEL, etc.)
- dart:math log shadowed by logger.dart export
Add singleFilenameFormat setting so singles/EPs can use a different filename template than albums. The format editor is reused with custom title/description. Dart selects the correct format based on track.isSingle before passing to Go, so no backend changes needed. Also fix isSingle getter to include all EPs regardless of totalTracks. Closes#271
Add a bottom sheet dialog that lets users choose which metadata field
groups to update during bulk re-enrich (cover, lyrics, album/album
artist, track/disc number, date/ISRC, genre/label/copyright).
Backend (Go):
- Filter FLAC Metadata struct and FFmpeg metadata map by selected
update_fields so non-selected groups preserve existing file values
- Guard Deezer extended metadata fetch with shouldUpdateField(extra)
- Title/Artist are never overwritten by re-enrich (search keys only)
- enrichedMeta response only includes selected field groups
Frontend (Dart):
- New re_enrich_field_dialog.dart bottom sheet with checkboxes
- FFmpegService embed methods gain preserveMetadata param that uses
-map_metadata 0 instead of -1 to preserve non-selected tags
- Hide selection overlay/bar before showing dialog, restore on cancel
- Fix setState-after-dispose guard in cancel branches
Cleanup:
- Remove dead code in library_tracks_folder_screen.dart
- Fix use_build_context_synchronously in main_shell.dart
- Suppress false-positive use_null_aware_elements lints
- Update l10n label from 'Title, Artist, Album' to 'Album, Album Artist'
- Delete dead metadata client and extract shared types to metadata_types.go
- Remove Yoinkify download fallback from Deezer, use MusicDL only
- Clean up retired settings fields and metadataSource
- Remove dead l10n keys for retired provider
- Add migration to strip retired provider from existing users' lyrics config
- Add artist_tag_mode setting (joined / split_vorbis) for FLAC/Opus multi-artist tags
- Split 'Artist A, Artist B' into separate ARTIST= Vorbis comments when split mode is enabled
- Join repeated ARTIST/ALBUMARTIST Vorbis comments when reading metadata
- Propagate artistTagMode through download pipeline, re-enrich, and metadata editor
- Improve library scan progress: separate polling intervals, finalizing state, indeterminate progress
- Add initial progress snapshot on library scan stream connect
- Use req.ArtistName consistently for Qobuz downloads instead of track.Performer.Name
- Add l10n keys for artist tag mode, library files unit, and scan finalizing status
