treating single newlines as paragraph boundaries for precise highlighting.
Update TTS context to conditionally use EPUB splitting based on document type.
Enhance PDFViewer to clear highlights when current sentence is null.
Add comprehensive tests for the new functionality and refactor existing ones.
- Rename and enhance text processing functions in nlp.ts for better handling of oversized texts, sentence boundaries, and PDF artifacts
- Update PDFViewer to add layout-aware highlighting with retry logic for sentence and word highlights
- Adjust PDFContext and TTSContext to use new normalized text functions

- Add `ChevronLeftIcon` and `ChevronRightIcon` to icon library.
- Update Playwright tests to reflect new navigation button labels.
- Relocated all audiobook-related API routes from `/api/audio/convert/*` to `/api/audiobook/*`.
- This change affects endpoints for chapter conversion, retrieval, deletion, and overall audiobook status.
- Updated client-side calls in `AudiobookExportModal.tsx`, `EPUBContext.tsx`, and `PDFContext.tsx` to reflect the new API paths.
- Modified API tests (`api.spec.ts`, `export.spec.ts`) to target the restructured endpoints.
- The new API structure provides better organization and a clearer, more consistent interface for audiobook functionality.
- Removed `onProgress` callback from `regenerateChapter` and related functions across `TTS`, `EPUB`, and `PDF` contexts to simplify the chapter regeneration API.
- Updated `AudiobookExportModal` to align with the refined regeneration API, including removing granular chapter progress display and adding a hint about TTS caching behavior.
- Introduced `TTSAudiobookChapter` interface and renamed `ContinuationMergeResult` to `TTSSmartMergeResult` and `PageTurnEstimate` to `TTSPageTurnEstimate` for better type consistency and clarity.
- Applied minor styling adjustments to buttons and listbox components in modals for visual consistency.
- Added `'use client'` directive to several client-side components for Next.js 13+ compatibility.
- Updated Dockerfile build command from `pnpm run build` to `pnpm build`.
- Added Playwright tests to verify backend chapter state after regeneration.
Migrates scattered configuration items and last document locations
from the legacy `config` table to new, dedicated Dexie stores.
- Introduces a singleton `app-config` table (`AppConfigRow`) to standardize
and structure all application settings in a single object.
- Creates a `last-locations` table for efficient storage of document read positions.
- Updates `ConfigContext` to utilize `dexie-react-hooks`' `useLiveQuery`
for reactive and simplified state management.
- Implements a database upgrade path (from DB_VERSION 4 to 5) to migrate
all existing user settings seamlessly.
- Simplifies config access and updates with new `getAppConfig` and `updateAppConfig`
utility functions.
- Removes the deprecated `config` table after successful migration.
- Updates consumers like `SettingsModal` and test helpers to align with
the new config structure.
- Reduce Playwright worker allocation from 75% to 50% for better resource management
- Disable parallel test execution temporarily to isolate flaky test behavior
- Enhance audio utility to fail fast on user cancellation, preventing unnecessary retries
- Consolidate test-specific utilities within individual test suites for better isolation
- Introduce export functionality test coverage with new export.spec.ts suite
introduce configurable smart sentence splitting with persisted state,
UI toggle, and EPUB/PDF contexts that send continuation metadata.
enhance TTS pipeline to merge cross-page sentences, manage carryover,
and trigger visual page changes during playback for smoother narration.
update README with kokoro quick-start guidance, remove the legacy
issues mapping doc, and add deterministic TTS mocks plus sample audio
for Playwright tests.
Introduce an in-memory LRU cache for TTS audio with configurable
size and TTL via TTS_CACHE_MAX_SIZE_BYTES and TTS_CACHE_TTL_MS.
Return X-Cache headers (HIT/MISS) and set route runtime to nodejs.
Cache key includes provider, model, voice, speed, format, text,
and optional instructions.
Normalize non-Kokoro multi-voice input to the first token while
preserving full voice string in the cache key. Default Deepinfra
model to hexgrad/Kokoro-82M when none is provided.
Fix Deepinfra Kokoro behavior by enforcing single-voice selection:
- ui: only enable multi-select when provider supports >1 voices
- voice utils: Deepinfra max voices set to 1
- tests: gate provider selection and multi-voice tests by CI and
increase timeout for stability
- Introduce voice utils (model detection, voice parsing/weights, limits)
- Enable Kokoro multi-voice strings across OpenAI/Deepinfra/custom providers
- Normalize non-Kokoro voices to single token for SDK calls
- Expose full Kokoro voice list for custom-openai Kokoro models
- Update TTS API to return audio as ArrayBuffer and improve logging
- Add multi-select UI for Kokoro voices with provider-based clamping
- Preserve Kokoro voice strings in TTSContext and coalesce restarts
- Merge multi-sentence quoted dialogue in NLP sentence splitter
- Update tests for single and multi-voice selection flows
- Isolate concurrent LibreOffice runs with per-job profile directories
(soffice -env:UserInstallation) and per-job temp folders
- Poll for generated PDF and verify stable file size before reading
- Consolidate temp artifacts under docstore/tmp and clean up via rm -r
- Add headless/nologo flags and improve error handling
ui(accessibility):
- ConfirmDialog exposes proper dialog roles
- DocumentFolder toggle adds type, aria-expanded, aria-controls, and title;
associate content panel with an id
- HTMLViewer wraps content in .html-container for HTML/TXT views
test: add comprehensive Playwright specs and helpers
- Accessibility, API health, deletion flows, folders, navigation, playback,
and upload scenarios
- Add sample.md and unsupported.xyz; update sample.pdf; extend helpers
ci: run Playwright workflow on version1.0.0 branch
Add comprehensive multi-provider TTS support enabling users to choose between OpenAI, Deepinfra, and custom OpenAI-compatible endpoints. Implement provider-specific voice management with automatic voice restoration per provider-model combination, and migrate package manager to pnpm for improved dependency handling.
Key changes:
- Add TTS provider selection (OpenAI, Deepinfra, custom-openai) in settings UI
- Implement provider-specific model and voice lists with dynamic fetching
- Add voice persistence per provider-model combination in savedVoices
- Support Deepinfra models: Kokoro-82M, Orpheus-3B, Sesame-1B with their voice libraries
- Migrate to pnpm with frozen lockfile for reproducible builds
- Update Docker configuration to use pnpm and Deepinfra API defaults
- Add migration logic for existing users to infer provider from stored baseUrl
- Update test helpers and Playwright configuration for Deepinfra API
- Add example docker-compose.yml with Kokoro-FastAPI integration
BREAKING CHANGE: Voice selection is now provider-model specific. Previously saved voices will be migrated to the new savedVoices structure, but users may need to reselect voices if switching providers.
