Release Release 6.3.0 · cporcellijr/bookbridge

[6.3.0] - 2026-02-23

Storyteller API v2 Requirement: The bridge has fully transitioned to the Storyteller REST API v2 endpoints (/api/v2/). You MUST update your Storyteller container to the latest version to use Bridge v6.3.0. Legacy Storyteller versions are no longer supported and will result in 404 connection errors.
Docker Compose Volume Mounts for "Forge": The new Auto-Forge pipeline requires proper volume mapping for directory transfers. Ensure your docker-compose.yml includes mappings for STORYTELLER_LIBRARY_DIR, BOOKS_DIR, and any relevant processing directories for the Forge tab to function without "Directory not found" errors.
Database Migration: This update includes a major database schema upgrade (Alembic) to support the Tri-Link architecture. Highly Recommended: Backup your database.db and legacy JSON files before pulling this update. If you encounter a boot-loop due to a locked database, simply deleting the DB and letting it rebuild is the fastest fix, as the bridge can auto-match most entries automatically.
KOSync "Stuck" Progress on Old Links: Books matched under older versions of the bridge might lack the original_ebook_filename required by the new Tri-Link architecture. If an older book stops syncing progress to KOReader after this update, simply delete the mapping from the dashboard and re-match it to rebuild the link correctly.

Tri-Link Architecture: Maintain a three-way link between ABS audiobook, KOReader ebook, and Storyteller entries.
Auto-Forge Pipeline: Automated downloading, staging, and hand-off to Storyteller for processing.
Hardcover.app Audiobook Support: Link specific editions and sync listening progress (in seconds).
Booklore & CWA (OPDS) Integration: Fetch ebooks from Booklore and OPDS sources, including backward-compatible fallbacks for Booklore v2.
Split-Port Security Mode: Run sync and admin UI on separate ports.
New Transcription Providers: Support for Whisper.cpp Server, Deepgram API, and CUDA GPU acceleration.
Advanced Anchor Mapping: Implemented BS4-to-LXML Hybrid Anchor Mapping and SMIL Extractor Smart Duration Mapping for perfect KOReader xpath generation.

UI Redesign: Horizontal dashboard cards, overhauled match pages, and responsive settings UI.
Progress Suggestions: Smart auto-discovery and suggestions for potential matches.
Dynamic Configuration: ABSClient web UI settings now take effect dynamically without requiring a restart.
Optimized Workflows: Restored automatic addition of collections and shelves post Auto-Forge processing.
Logging Standardization: Consistent emoji prefixes and log levels across the entire codebase.

KOReader Sync: Fixed KOReader sync crashes caused by an XPath double body tag issue.
KOSync Sync Integrity: Prevented destructive progress pushes, preserved manual hash overrides, and fixed KOSync hash overwrites by Storyteller artifacts.
Storyteller Stability: Fixed race conditions in Storyteller ingestion and removed conflicting Storyteller fallback collection logic.
System Stability: Fixed special characters in filenames breaking glob searches, corrected Booklore shelf assignment issues during batch matching, and resolved legacy KOSync client headers, legacy exception types, and sync position payloads.
Database Persistence & Migrations: Forced absolute paths for SQLite connections to prevent ephemeral Docker data loss, auto-upgraded legacy DB-migrated books, and prevented legacy DB crashes on startup via Alembic stamping.
XPath Hardening: Defaulted Crengine-safe XPath suffixes, and hardened generation against fragile inline tags to prevent parsing drift.

Unified DB Architecture: Transitioned to SQLAlchemy for alignments, transcripts, and settings.
Alembic Migrations: Improved migration tracking and safety checks.
Storyteller API: Removed direct DB access in favor of strictly API-based communication; legacy Storyteller DB fallback has been deprecated.
