SpotifyBU 1.7.0

SpotifyBU 1.7.0

SpotifyBU 1.7.0 promotes Plex playlist sync from the dev track to the stable
release. Spotify playlists can now sync matched local tracks into Plex playlists
alongside the existing Navidrome workflow.

Added

• Settings now stores optional Plex server URL, token, and music library key
  values for playlist sync.
• Playlist views can replace, append, or full-sync a same-named Plex playlist
  from matched Spotify tracks.
• Plex playlist sync now carries Spotify playlist artwork into Plex when
  artwork is available.
• Plex matching checks scanned, accessible, and playable files before adding
  tracks to a playlist, and reports skipped tracks in the UI.
• Music library organize ignores can be added and removed when a matched file
  should intentionally stay outside the canonical layout.

Changed

• Provider downloads and identity-tag backfills now add Navidrome-compatible
  release tags in addition to SpotifyBU identity metadata.
• Identity-tag backfill progress handling is more resilient for existing
  libraries.
• Organize matching is stricter about the expected source and destination paths.

Verified

• TypeScript check passes with tsc --noEmit.
• Production build passes with next build.
• Unit tests pass with npm test.
