v2.0.13

What's New

v2.0.13 brings major reader experience improvements and comprehensive code quality enhancements. This release introduces continuous scrolling for seamless chapter transitions, advanced TTS synchronization features including per-novel settings and dual-context stitching, and improved backup management with versioned schemas. The codebase has undergone significant refactoring with 200+ new tests and enhanced type safety across critical TTS components.

✨ Features

• Continuous Scrolling: Chapters now transition seamlessly without page breaks, with configurable stitch and transition thresholds in settings
• Per-Novel TTS Settings: Each novel can now have its own TTS configuration (voice, speed, pitch) that auto-loads when opening a chapter
• TTS Stitched Chapters: Fixed TTS restart in stitched chapters with dual-context synchronization for uninterrupted playback
• Advanced Navigation Tab: New reader settings tab with continuous scrolling, chapter boundary, and stitch threshold options
• Backup Schema v2: Implemented versioned backup system with migration pipeline and improved auto/manual backup separation

🐛 Bug Fixes

• Filter FAB Crash: Resolved crash in library filter functionality and fixed duplicate key warnings
• EPUB TTS Sync: Fixed chapter title synchronization at Paragraph 0 for EPUB export
• WebView Debug Logging: Corrected DEBUG variable scope that was causing render freeze
• TTS-Triggered Trim: Completed trim functionality with getChapter() reload for clean state management
• Backup Pruning: Fixed logic to properly separate auto and manual backup pruning

🔧 Code Quality

• 200+ New Tests: Comprehensive test coverage for database queries (Category, History, Novel, Repository, Stats), TTS error paths, and backup schema validation
• Type Safety: Replaced any types with proper TypeScript types, added promise error handling to 10 unhandled promises
• TTS State Machine: Added TTSState.ts with explicit state transition validation and 26 state transition tests
• Rate-Limited Logger: New @utils/rateLimitedLogger replaces console.log calls to reduce dev log spam
• React Native Build: Fixed CMake autolinking issues for google-signin, edge-to-edge, and file-access modules

📜 Commits

• Core TTS Enhancements: Implemented continuous scrolling with DOM stitching, dual-context synchronization for TTS restarts in stitched chapters, per-novel TTS settings with auto-load on reader entry, and comprehensive TTS state machine with transition validation. Fixed multiple TTS race conditions and synchronization issues including scroll sync dialog enhancements.
• Reader Experience: Added invisible chapter transitions, auto-mark short chapters feature, configurable stitch/transition thresholds, and continuous scrolling modals. Fixed EPUB TTS synchronization with chapter title at Paragraph 0 and resolved DEBUG variable scope causing render freeze.
• Backup System: Implemented versioned schema v2 with migration pipeline, separated auto/manual backups with fixed pruning logic, and added comprehensive backup schema validation tests.
• Testing Infrastructure: Added 125+ database query tests (Category, History, Novel, Repository, Stats), TTS state transition tests (26 tests), TTSHighlight error path tests, and backup schema validation tests. Total of 200+ new tests across core services.
• Code Quality & Type Safety: Replaced any types with proper TypeScript definitions, added promise error handling to 10 unhandled promises, implemented rate-limited logger to replace console.log, fixed useEffect dependencies, and resolved lint warnings across hooks and styles.
• Bug Fixes: Resolved filter FAB crash, duplicate key warnings, follow/unfollow failure handling, and WebView console log property name issues.
• Documentation: Added JSDoc comments to TTSAudioManager, updated code review action plan with verification results, and added comprehensive specs for continuous scrolling, TTS features, and code quality audits.
