- Introduce a toggleable grid/list view for the document list, enhancing organization and display flexibility. This involved updates across `DocumentList`, `DocumentFolder`, `DocumentListItem`, and `SortControls`.
- Add a new `CodeBlock` component and integrate detailed Docker-based self-hosting instructions into the footer.
- Enhance privacy policy popover with clearer details on Deepinfra usage and strongly recommend self-hosting for secure experience.
- Implement conditional rendering and feature gating based on the `isDev` environment variable, differentiating features between the production demo and self-hosted instances. Affected components include `page.tsx`, `DocumentSettings.tsx`, `SettingsModal.tsx`, and `config.ts`.
- Clarify that advanced features like audiobook export and word-by-word highlighting via `whisper.cpp` are exclusive to self-hosted setups and are disabled in the demo.
- Expand the list of supported document types on the homepage to include MD and TXT.
- Integrate new `ListIcon`, `GridIcon`, and `CopyIcon` to support UI enhancements.
- Add a custom `xs` breakpoint in `tailwind.config.ts` for improved responsive design.
- Implement custom previous/next page buttons for EPUB viewer.
- Display current page number out of total pages.
- Introduce an in-viewer, toggleable table of contents (TOC) for quick chapter navigation.
- Hide default `react-reader` navigation arrows and title bar to prevent redundancy.
- Adjust `react-reader` styles to optimize content area and ensure custom controls are visible.
- Update description for EPUB theme setting in document settings.
- Add `ChevronLeftIcon` and `ChevronRightIcon` to icon library.
- Update Playwright tests to reflect new navigation button labels.
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.
- 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.
- Offload computationally intensive text matching for real-time highlighting to a dedicated Web Worker, ensuring the main thread remains responsive during playback.
- Implement a new overlay-based highlighting system that renders independently of the PDF's text layer, providing smoother and more reliable visual feedback without interfering with document rendering.
- Introduce a new setting allowing users to enable or disable real-time text highlighting in PDFs, offering personalized control over the reading interface.
- Upgrade the underlying text comparison algorithm to Dice similarity for more accurate and context-aware matching of spoken words to on-screen text, improving synchronization precision.
- Improve sentence boundary detection, especially for quoted dialogue and complex structures, by enhancing the NLP processing logic, leading to a more natural audio-text flow.
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.
