Introduce sentence and word highlighting for HTML/TXT/MD documents, including new config options (`htmlHighlightEnabled`, `htmlWordHighlightEnabled`) and synced user preferences. Update the HTML viewer to support these highlights using custom spans, and add corresponding CSS styles. Extend document settings to allow toggling these features. Implement block-level locator sorting and display improvements. Add audiobook export support for HTML documents, including adapter and pipeline integration.
- Add `htmlHighlightEnabled` and `htmlWordHighlightEnabled` to config, user state, and Dexie storage
- Update HTML viewer to apply and manage highlights for sentences and words
- Add CSS for HTML highlight classes and scroll margin
- Extend document settings UI for HTML highlight toggles
- Support HTML audiobook export in modal and pipeline
- Improve block locator sorting and sidebar display for HTML
- Add HTML audiobook adapter and block parsing utilities
Update multiple UI panels to use skeleton components instead of loading text or spinners.
Standardize loading states in AudiobookExportModal, AdminFeaturesPanel, AdminProvidersPanel,
DocumentSelectionModal, and SegmentsSidebar for improved visual consistency and user feedback.
Transition all TTS-related logic, types, and UI to use the new providerRef/providerType model in place of legacy ttsProvider fields. Introduce a centralized tts-provider-policy module to encapsulate provider/model capability checks, default value resolution, and compatibility logic. Update all API routes, contexts, hooks, components, and tests to use providerRef and providerType, ensuring consistent handling of built-in and shared TTS providers. Remove legacy defaultTtsModel config in favor of per-provider defaults and shared provider admin control. Add the showAllProviderModels runtime flag to restrict users to provider default models when desired.
BREAKING CHANGE: ttsProvider fields are replaced by providerRef/providerType throughout the codebase; defaultTtsModel config is removed in favor of per-provider defaults.
Introduce configurable segment preloading depth, sentence lookahead, and TTS segment max block length for both PDF and EPUB readers. Add new settings to user preferences, config context, and document settings UI. Refactor TTS segment splitting logic to support per-user max block length and propagate these options through PDF/EPUB adapters and TTS segment generation. Update API, manifest pagination, and segment deduplication for improved performance and correctness. Add tests for new NLP options and manifest logic.
BREAKING CHANGE: TTS segment splitting and manifest APIs now require max block length and preloading parameters; user config schema updated.
Introduce SegmentsSidebar component and supporting reader UI for segment-level
navigation and inspection. Add TTS segments manifest and clear API endpoints to
enable efficient retrieval and management of segment variants. Update TTS
segment schema to include settings_hash for improved lookup and indexing,
and adjust indexes to use settings_hash instead of settings_json. Update
contexts and types to support segment variant display and interaction.
This enhances document navigation and TTS segment management for end users.
- Updated environment variables documentation to include Replicate as a TTS provider option.
- Added Replicate to the sidebar for TTS provider guides.
- Included Replicate as a dependency in package.json and pnpm-lock.yaml.
- Enhanced audiobook chapter generation to normalize native speed settings based on the TTS provider.
- Improved error handling in TTS API routes to provide retry information for rate-limited responses.
- Updated AudiobookExportModal to reflect native speed support for Replicate models.
- Modified SettingsModal to set default model for Replicate.
- Enhanced SpeedControl component to conditionally render native speed controls based on provider support.
- Updated TTSContext to utilize effective native speed for TTS requests.
- Implemented Replicate request handling in the TTS generation logic.
- Added new documentation for configuring Replicate as a TTS provider.
- Introduce a shared tts-provider-catalog to centralize provider/model/voice defaults
and feature flags (supportsTtsInstructions, providerSupportsCustomModel, resolveProviderModels,
getDefaultVoices, etc.). Replace ad-hoc provider logic across server and client with catalog calls.
- Replace inline voice/model UI logic in SettingsModal, AudiobookExportModal, TTSContext,
generate server code, and voice hook to use catalog helpers (resolveTtsSettingsViewModel,
supportsTtsInstructions, getDefaultVoices).
- Extract audiobook generation responsibilities into a small client-side pipeline:
- Add createEpubAudiobookSourceAdapter and createPdfAudiobookSourceAdapter adapter modules
to prepare chapters from EPUB/PDF sources.
- Add runAudiobookGeneration and regenerateAudiobookChapter pipeline functions to handle
chapter preparation, progress tracking, request header construction, and retry/abort behavior.
- Wire adapters/pipeline into EPUBContext and PDFContext to simplify and centralize audiobook flow.
- Move config preference helpers out of ConfigContext into dedicated client modules:
- buildSyncedPreferencePatch (lib/client/config/preferences.ts)
- applyConfigUpdate and getVoicePreferenceKey (lib/client/config/updates.ts)
- Use these helpers in ConfigContext to keep update logic small and testable.
- Add TTS settings view model resolver (lib/client/settings/tts-settings.ts) and tests
for the tts-provider catalog and config helpers (tests/unit/tts-provider-catalog.spec.ts).
- Minor usages updated: AudiobookExportModal, SettingsModal, useVoiceManagement, TTSContext,
server tts generation, and various context files to consume the new modules.
Why: Reduce duplication, improve testability, and separate concerns for provider metadata,
UI view-model logic, and audiobook generation flow. Breaking changes: none.
- Removed unused imports and types from TTS route.
- Consolidated TTS buffer generation logic into a new module.
- Implemented caching for TTS audio buffers using LRU cache.
- Updated TTS request handling to support instructions for specific models.
- Refactored audiobook chapter creation to use new TTS generation logic.
- Simplified error handling and response management in TTS API.
- Enhanced client-side logic to manage TTS requests and retries.
- Updated types to reflect changes in TTS request payload structure.
- Introduce `USE_ANONYMOUS_AUTH_SESSIONS` to make guest access an opt-in feature.
- Transition root-level pages into `(app)` and `(public)` route groups for improved access control.
- Adopt Figtree as the primary typeface and implement a pre-render theme initialization script.
- Decouple audiobook chapter processing into a standalone API route and harden resource ownership logic.
- Replace the legacy footer with a unified layout and add skeleton loading states for document lists.
- Update environment documentation and test suites to align with the revised routing and auth flows.
BREAKING CHANGE: The audiobook generation API has been restructured, moving specific chapter logic to `/api/audiobook/chapter`.
Update modal components to start from top on mobile devices and center on larger screens, improving usability across screen sizes. Also refine transition handling in privacy popup for cleaner unmounting.
- Add scroll functionality to the chapter list to prevent content
overflow.
- Conditionally adjust the positioning of chapter action menus
to ensure they remain visible within the modal, preventing
them from being cut off for chapters at the top of the list.
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`.
- 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.
- Reorganized utility modules from `src/utils` to `src/lib` for clearer separation of concerns.

- 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.
