Release Notes - 7.13.0

BookBridge has a New interface (beta), Suggestions grows into Discover for every
reader, and reader apps get a Device API for word-level read-along. Classic stays
the default, and you can switch between the two at any time without losing anything.

Discover finds audiobook/ebook pairs, ebooks without an audio match, and any book in
your libraries, and each reader now sees only their own scans and queue. A book you
download from CWA in KOReader matches on its own, even if you never added it.

What's New

• New interface (beta). Choose New interface beside the account menu to try
  it; Classic | New switches back. It has a redesigned Library (Covers, Spines
  and List), a strip on each cover showing where the book is linked and which app
  led its last sync, your progress right on the cover, a book drawer that shows
  your current audiobook chapter (#428), search with Ctrl K / ⌘K, day and night
  themes, and phone navigation.

• Discover replaces Suggestions and Add Book. Three tabs: Pairs (audiobook +
  ebook matches to review), Ebook Only (ebooks with no audiobook match, with
  Find audiobook, Create ebook-only, Hide for now and Ignore), and Search (the
  old Add Book). Books group by series, filters are remembered per tab, and a scan
  that could not read every source says so. Every reader can use it and sees only
  their own results. A new admin setting, Ignore local files in Suggestions,
  leaves locally scanned files out of Pairs and Ebook Only.

• Device API for reader apps (#579). An app that pairs an ebook with its
  audiobook can find a book by its Grimmory or BookOrbit id, download a word map to
  highlight words as the narrator reads them, and ask BookBridge to sync one book
  right away. Apps sign in with the reader's KOSync account. Contributed by
  @adam-fox.

• Transcription pre-flight (#528). Before a long Whisper fallback, Processing
  shows the EPUB's words per audiobook minute, and how it compares with your other
  books once five are measured, so a wrong pairing (an omnibus with one narrated
  volume) stands out early. It never pauses work.

• Stats is open to every reader for their own reading and listening.

Fixed

• CWA downloads match without adding them first (#582). A book downloaded
  through KOReader's CWA (OPDS) catalog now finds its EPUB in your Calibre library
  and is matched on your first sync. Requires CALIBRE_LIBRARY_PATH under
  BOOKS_DIR or EXTRA_EBOOK_DIRS.
• Forced alignment respects a CPU-limited container (#580). QuartzNet uses the
  CPUs the container can actually use; ALIGN_THREADS overrides it. Contributed by
  @eschatus.
• BookOrbit: an ebook you have not opened yet now receives its first synced
  position instead of failing with a 403.
• Hardcover: a matched book missing from your Hardcover library is added back as
  Want to Read and its progress syncs, instead of being skipped every sync.
• Ebooks and read-alongs: EPUBs whose navigation page has no table of contents
  read normally, and read-along EPUBs build for books saved with Windows line endings.
• Audiobookshelf collections: adding a book that is already in a collection is no
  longer a failure, and books land in the right collection when two libraries share
  a name.
• Diagnostics no longer include your ebook file names.
• Processing: removing a job while it runs no longer brings it back.
• Multi-user: one reader's automatic matching no longer re-points an audiobook
  another reader already matched.

Upgrading

Back up your /data directory, then pull the new image and restart:

docker compose pull && docker compose up -d

This release adds three database migrations, applied automatically on start: a
per-reader owner for suggestions, stored pre-flight measurements, and the leader of
each reader's last sync. Nothing needs to be rebuilt beyond the usual image pull.
BridgeSync is unchanged (0.9.10).

Operational Notes

• Classic stays the default. Nothing changes for a reader until they choose
  New interface; each reader's choice is their own.
• Discover results are now kept per reader. Existing suggestions carry over to
  the admin; other readers click Scan Library on Discover to get their own.
• Known issue (already in 7.12.0): a targeted sync of a book nobody has started,
  whose audiobook narrates its parts in a different order from the EPUB (for example
  an anthology), can move the ebook to the middle of the book. It can be triggered by
  a KoSync update at 0%, Sync Now, or a reader app's sync request. A fix is
  planned for the next release.
