Refactor chapter API to use new coerceAudiobookGenerationSettings utility for
validating and migrating audiobook metadata. Add src/lib/server/audiobooks/settings.ts
with shared logic and introduce corresponding unit tests to ensure correct
settings migration and validation.
Move changelog version check effect from SettingsModal to a new
scheduleChangelogCheck utility for improved modularity and testability.
Add unit tests for changelog check scheduling behavior.
Integrate changelog version check on settings open, triggering the changelog
panel when a new app version is detected. Refactor user preferences storage to
support metadata via payload utilities, enabling version tracking and future
extensibility. Add API endpoint for changelog version check and related tests
for changelog and preferences payload logic.
Update SettingsModal to use conditional rendering for the changelog panel,
displaying the main settings navigation only when the changelog is closed.
Refactor mobile and desktop navigation layout to improve maintainability.
Add missing ChevronRightIcon import for icon consistency.
Introduce changelog feed manifest support, including client and shared
utilities for fetching and parsing changelog data. Add a new
Settings modal panel for viewing changelog entries, with version
detection based on the current app version. Expose a configurable
changelog feed URL in both environment variables and admin panel
runtime settings. Update documentation and deployment workflow to
support changelog feed generation and consumption. Include unit tests
for changelog 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.
Eliminate the showAllDeepInfraModels runtime/admin config and all code paths
that allowed restricting Deepinfra's model catalog. Deepinfra now always
shows the full model list regardless of API key or environment variable.
Update documentation, environment examples, admin panels, runtime config,
provider catalog logic, and tests to reflect this change.
Move shared button, input, and listbox styles to a new formPrimitives module
used across admin panels, settings, and document settings. Update admin and
settings components to import these styles from the new location. Refactor
DocumentSelectionModal to use a direct files prop with loading and error
states, removing fetcher logic and internal fetch state. Add a custom hook
for library document queries. Clean up legacy admin/ui primitives and
standardize segmented controls and section layouts.
Integrate @tanstack/react-query in SettingsModal to cache and prefetch library
documents, improving import modal responsiveness. Refactor SegmentsSidebar to
use infiniteQuery for TTS segments manifest, enabling pagination, cache
invalidation, and consistent data fetching. Remove legacy fetch state logic in
favor of react-query state management.
Adopt new layout files for app, epub, html, and pdf routes to standardize
Next.js nested layout structure. Refactor SegmentsSidebar to accept an explicit
epubBookRef prop, decoupling it from internal context. Enhance EPUB resize hook
to ignore initial baseline rect and avoid unnecessary TTS interruptions on load.
Simplify Providers by removing legacy context nesting and conditional logic.
Adopt @tanstack/react-query for data fetching and cache management in admin
settings, provider management, shared provider hooks, and context providers.
Replace legacy useState/useEffect data loading with react-query's useQuery and
useMutation patterns. Refactor document, rate-limit, and shared provider
contexts to use query keys and cache invalidation for consistent state across
the app. Add QueryClientProvider to root providers. Update package.json to
include react-query dependency.
Remove fallbackProviderRef usage from settings and config context to streamline
provider resolution. Adjust normalizeLegacyProviderRef to retain 'default-openai'
unless a non-default fallback is explicitly provided. Update provider listing to
enforce deterministic ordering by updatedAt, createdAt, and slug. Expand unit tests
to verify provider ordering, legacy ref normalization, and selection logic.
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.
Add a dedicated Admin Panel documentation page detailing management of shared TTS providers and site features via the admin UI. Update all TTS provider guides, environment variable references, and deployment docs to clarify the new runtime configuration model: environment variables serve as first-boot seeds only, with ongoing management handled through the admin interface. Revise sidebars and cross-links to include the new admin panel docs and clarify the distinction between legacy env-based and admin-managed configuration.
Add database-backed runtime configuration for feature flags and TTS provider credentials, editable via a new admin UI panel. Replace static NEXT_PUBLIC_* and TTS provider env vars with admin-managed settings stored in the database and injected at SSR for client access. Implement admin-only panels for managing shared TTS provider credentials (with encrypted API keys) and live site feature flags. Add schema migrations, API routes, React contexts, and hooks for SSR-injected runtime config and live updates. Update client and server logic to resolve configuration from the database at runtime, enforcing admin restrictions and supporting migration from legacy env-based config.
BREAKING CHANGE: Feature flags and TTS provider credentials are now managed at runtime via the admin UI. Environment variables are only used for initial seeding and are ignored after first boot. Existing deployments must migrate configuration to the admin panel.
Eliminate the deprecated `/api/tts` route and its client usage, consolidating TTS generation logic under chapter and segment endpoints. Update client API utilities to remove direct TTS buffer fetching and improve error propagation for chapter generation failures. Extend TTS segment error metadata to include upstream rate limit and retry details, and standardize error typing in shared types. Adjust tests and helpers to reflect the new TTS mocking approach and endpoint structure. This streamlines TTS API surface and enhances error reporting consistency.
Move daily quota exceeded problem response logic to a dedicated utility in `lib/server/rate-limit/problem-response`. Refactor API routes to use the new builder and remove duplicated formatting code. Update all relevant imports for consistency. This improves maintainability and ensures uniform error responses across TTS endpoints.
Move `epub-word-highlight`, `tts-epub-handoff`, and `tts-epub-preload` from shared to client/epub to clarify their usage and improve bundling. Update all imports to use new client paths. Extend TTS and sidebar logic to support HTML document progress tracking and restoration, introducing a new location format for HTML and consistent handling for non-EPUB readers.
BREAKING CHANGE: EPUB TTS utilities relocated to `lib/client/epub`; update import paths. HTML progress persistence now uses a new format incompatible with previous versions.
Redesign TTS segment storage by decomposing the `tts_segments` table into two normalized tables: `tts_segment_entries` for unique segment identity and locator projection, and `tts_segment_variants` for per-settings audio variants. Update schema, queries, and API routes to use the new structure, including manifest pagination and segment resolution logic. Refactor segment locator handling to use stable projections and manifest cursors. Migrate tests and data cleanup utilities to support the new model.
BREAKING CHANGE: Database schema for TTS segments is now split into entry and variant tables; all code and consumers must use the new structure. Persisted data and APIs relying on the old `tts_segments` table are incompatible.
Implement strict validation for EPUB TTS segment locators, requiring stable spine coordinates (`spineHref`, `spineIndex`, `charOffset`) and rejecting legacy CFI-only locators. Introduce `segmentKey` as a normalized identity derived from segment text, used for robust merging and deduplication of synthesized and persisted segments. Update database schemas, API routes, and manifest logic to support the new locator format and segmentKey. Add helpers for locator resolution and segmentKey construction, with comprehensive unit tests for identity, normalization, and manifest grouping.
BREAKING CHANGE: Persisted EPUB TTS segment locators must now include stable spine coordinates; legacy CFI-only locators are no longer accepted. Consumers must handle the new `segmentKey` field for segment identity and merging.
Refactor TTS segment identification to support canonical segment keys, decoupling segment IDs from locator and index for more robust deduplication and handoff. Add `segmentKey` to segment types, manifest, and ensure route. Implement natural sorting for EPUB CFI locations and segment locators using new comparison utilities. Update sidebar and manifest helpers to use locator-aware sorting. Add foundational modules for EPUB word highlighting, TTS segment planning, and EPUB handoff logic. Expand types and tests to cover new canonical segment and locator behaviors.
BREAKING CHANGE: TTS segment IDs now support canonical segment keys; APIs and manifest consumers must handle `segmentKey` and updated locator comparison logic.
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 logic to provide previous text context for TTS sentence splitting,
enabling more accurate prefix stripping and improved handling of segment
boundaries. EPUB and PDF providers now supply previous segment text, and
TTSContext leverages this context to avoid redundant continuation logic.
This enhances TTS playback continuity and reduces repeated or truncated
sentences across segment transitions.
Update segment manifest API to group segments by both index and locator
attributes, ensuring distinct segment variants are not merged incorrectly.
Adjust SegmentsSidebar logic to select the most relevant segment per index
based on locator match and recency, improving sidebar accuracy when
multiple locator variants exist for a segment.
Update TTSContext to track manual pause epochs, ensuring explicit user
pauses are respected during async sentence splitting and playback state
restoration. Adjust TTSPlayer button disabling logic to allow pausing
while processing. Move and improve pauseTTSAndVerify helper for robust
cross-browser TTS pause assertions, replacing local test implementations.
Update expectDocumentListed to use polling for document link visibility.
Standardize aria-labels in DocumentHeaderMenu and ReaderSidebarShell to use
"Hide" and "Close" phrasing for improved accessibility and user experience.
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.
Switch tts_segments schema to use settings_json (jsonb for Postgres, text for SQLite)
instead of settings_hash. Update related indexes and migration SQL. Regenerate
Drizzle snapshots to reflect the new structure. This improves flexibility for
storing TTS settings and enables more robust segment lookups.
Introduce `playbackRunIdRef` and `invalidatePlaybackRun` to ensure that playback
state is correctly reset on abort and content changes. Update abort and navigation
handlers to call `invalidatePlaybackRun`, preventing duplicate or stale playback
runs, especially in scenarios with rapid restarts or browser-specific audio event
quirks. This addresses issues where playback could become stuck or behave
unexpectedly due to outdated in-flight guards.
Remove legacy TTS segment manifest and audio endpoints in favor of new presigned and fallback audio URL approach. Update segment manifest structure to include `audioPresignUrl` and `audioFallbackUrl` fields, deprecating the previous `audioUrl`. Refactor segment ensure logic and TTS context to utilize the new playback source model. Add server utilities for generating presigned S3 URLs and introduce new API routes for presign and fallback audio retrieval. Clean up obsolete client API functions and types to reflect the new manifest format.
Expand and clarify documentation for TTS segment storage, including key layout, cleanup, and CLI access in object storage. Add details on the `tts_segments` schema and migration process. Revise local development and Docker quick start guides with improved prerequisites, platform-specific setup instructions, and updated TTS provider references. Document new usage of `AUTH_SECRET` for TTS segment text fingerprinting.
Introduce TTS segment support with new database tables and migrations for both Postgres and SQLite. Implement segment ensure, audio, and manifest API endpoints, segment storage in S3, and segment authorization logic. Update TTS context and client API to use segment-based synthesis and retrieval. Add server-side helpers for segment ID, settings hash, locator normalization, and audio probing. Extend user data cleanup and teardown logic to remove TTS segment objects. Add unit tests for segment helpers.
BREAKING CHANGE: TTS synthesis now uses segment-based storage and APIs; database migrations required.
Document observed S3 `InternalError` regressions with SeaweedFS 4.19 in
object storage, local development, and Docker quick start guides. Clarify that
version 4.18 is pinned in CI and Docker builds for reliability while
compatibility is investigated.
Update CI workflow and Dockerfile to use chrislusf/seaweedfs:4.18 instead of
latest. This avoids upload regressions observed with version 4.19 and ensures
consistent builds.
Introduce pauseActiveHowl to centralize audio pause logic, ensuring consistent
cleanup and media session state updates. Update pause and togglePlay to use the
new helper, enabling accurate resume of paused audio and improved error
handling. Enhance Howl onpause event to synchronize playback state and clear
timeouts.
