- switch better-auth to drizzleAdapter, add auth helpers (`getAuthContext`, `requireAuthContext`, `requireAudiobookOwned`), and make `useAuth`/`useAuthSession` safe no-ops when auth is disabled
- persist documents/audiobooks in DB with ownership checks, unclaimed fallback, and ref-counted deletes; add FS scan helper for no-auth mode
- gate docx-to-pdf, library, voices, whisper, and migration endpoints behind auth when enabled
- add unclaimed data scan/claim flow with `/api/user/claim`, `ClaimDataModal`, and server-side scan/claim helpers
- refactor rate limiting and account deletion to use Drizzle tables (`user_tts_chars`, `user`)
- run migrations via `scripts/migrate-if-auth.mjs` (auto on `pnpm start` + `pnpm migrate`), remove Docker entrypoint and old better-auth migration file
- update README and lockfile for the new migration workflow and dependencies
- Add device ID and IP-based rate limiting to prevent abuse
- Refactor UI components for better header menus and settings

- Add rate limiting for TTS API with daily character limits for authenticated and anonymous users
- Integrate SQLite and PostgreSQL database support for user sessions and data persistence
- Update UI components to include authentication flows, user menu, and privacy popup
- Modify Dockerfile and package.json for new dependencies and entrypoint script
- Bump version to v1.3.0
- Add logic to split oversized sentences in `splitTextToTtsBlocksEPUB` using `splitOversizedText` to ensure blocks stay within `MAX_BLOCK_LENGTH`
- Remove `extractRawSentences` and `processTextWithMapping` functions as they are no longer needed
- Update tests to reflect the changes, including a new test for oversized sentence splitting and removal of related test suites
Introduce `splitTextToTtsBlocksEPUB` function to handle EPUB text splitting,
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
- Expand unit tests for new splitting behaviors, including long texts and punctuation preferences
- Introduces `DocumentPreview` component to display rich previews for documents.
- PDFs generate a thumbnail of their first page.
- EPUBs extract and display their cover image.
- HTML, TXT, and Markdown files show a text snippet.
- Refactors document list and folder views to a responsive grid layout.
- Expands main content areas to accommodate the new grid.
- Updates Dockerfile to use Node.js LTS image.
- Updates various development and runtime dependencies.
Abstracted direct fetch calls across components and contexts into new functions within `src/lib/client.ts`. This provides a consistent and centralized interface for interacting with backend APIs.
- Introduced `src/lib/client.ts` to encapsulate API request logic.
- Standardized audio buffer types (`TTSAudioBuffer`, `TTSAudioBytes`) in `src/types/tts.ts`.
- Moved client-specific request types (`TTSRequestPayload`, `TTSRequestHeaders`, `TTSRetryOptions`) to `src/types/client.ts`.
- Updated API routes and consumer components/contexts to leverage the new client library functions and type definitions.
- Removed `src/utils/audio.ts` as its utility functions are now part of `src/lib/client.ts`.
- Introduce `/api/whisper` endpoint which uses `whisper.cpp` (via a `WHISPER_CPP_BIN` executable) and `ffmpeg` to generate word-level audio alignments from provided audio and text.
- Integrate word-level alignments into `TTSContext`, tracking the currently spoken word based on audio seek position and provided timestamps. Alignments are cached in-memory and fetched asynchronously.
- Add new configuration options (`pdfWordHighlightEnabled`, `epubWordHighlightEnabled`) to `ConfigContext` and `Dexie` for enabling/disabling the feature.
- Implement visual word highlighting in both `PDFViewer` and `EPUBViewer` by mapping TTS-aligned words to rendered text elements.
- Enhance `EPUBContext` and `PDFContext` with new `highlightWordIndex` and `clearWordHighlights` functions, utilizing fuzzy string matching (`cmpstr`) to robustly align spoken words with displayed text for accurate highlighting.
- Update `DocumentSettings` to include user-facing toggles for the new highlighting modes.
- Reorganized utility modules from `src/utils` to `src/lib` for clearer separation of concerns.
- Introduced new, dedicated type definitions in `src/types` for improved type safety in configuration and TTS API interactions.
- Replaced `src/types/appConfig.ts` with `src/types/config.ts`.
- Added `src/types/tts.ts` for TTS request payloads, error structures, and retry options.
- Updated module imports across several contexts (`Config`, `EPUB`, `HTML`, `PDF`, `TTS`) and components to reflect the new `lib` and `types` locations.
- Enhanced TTS API request and error handling in `src/app/api/tts/route.ts` and TTS-consuming contexts with explicit types.
- Simplified `ProgressCard`, `ProgressPopup`, and `AudiobookExportModal` components by removing the `isProcessing` prop, centralizing processing state management.
- Streamlined `HTMLContext` by removing `createFullAudioBook` and `isAudioCombining` properties, focusing its scope.
