BetterTTS v0.17.0

Premium production-workspace redesign for the web and Windows desktop app. Adds persistent workspace navigation, real Output/Queue/Library tabs, integrated output transport, compact properties controls, neutral dark/light themes, responsive mobile controls, expanded visual smoke coverage, and branded Windows packaging.

v0.15.0

Changed: Reworked the studio shell into a professional workstation layout with a six-tile command summary, side-by-side script/output workbench, tabbed waveform-style output deck, denser queue/library treatment, refreshed control-console modules, and responsive dark/light polish. Fixed: Updated the rendered smoke check to follow the current Script surface label after the interface copy refresh.

v0.14.0

Deep audit hardening release. Includes import/library/queue recovery guardrails, UI accessibility and contrast fixes, diagnostics privacy hardening, bounded article imports, safer service-worker cache keys, exact Kokoro voice-bin validation, BGM input guards, and queue export size preflights. Verification: npm test, npm run lint, npm run license:runtime, npm run build, npm run smoke.

v0.13.0

Roadmap drain release: adds experimental Piper-plus engine wiring, offline/runtime diagnostics hardening, document import and playback reliability improvements, queue editing, local smoke coverage, and v0.13.0 version sync. Verified locally with npm test, npm run lint, npm run license:runtime, npm run build, Playwright smoke, and synced Kokoro/Piper dist assets.

v0.12.0

Changed

• Reworked the main studio into a premium workstation interface with compact top chrome, runtime status, editor toolbar, output deck tabs, persistent queue/library empty states, inspector-style engine controls, a clearer generation module, and a bottom system rail.
• Refined dark and light theme tokens, table surfaces, empty states, mobile toolbar collapse, toast placement, and responsive queue/library layout.

Fixed

• Added an explicit captions track fallback for generated audio elements so local lint is clean and result playback keeps an accessibility-compatible media structure.

v0.11.0

v0.11.0

Added:

• Migrates the shared Transformers.js runtime to 4.2.0 with a root npm override so kokoro-js, Supertonic, timestamped Kokoro, and direct tensor paths resolve to v4.
• Adds KittenTTS WebGPU engine with Nano/Micro/Mini model selection and 8 English voices.
• Adds multilingual Kokoro voices for Spanish, French, Hindi, Italian, and Brazilian Portuguese.
• Adds word-level Kokoro timestamps, Supertonic, self-hosted Kokoro q8 assets, Signalsmith pitch shifting, and chaptered M4B export from the completed roadmap drain.

Changed:

• Download progress now prefers Transformers.js v4 aggregate byte totals.
• Tests now cover 114 assertions across 15 suites.

Verification:

• npm test: 114 passing
• npm run lint: baseline media-caption warning only
• npm run build: passed
• npm run sync:kokoro: synced 32 Kokoro assets
• Browser QA: Kokoro WASM q8, Kokoro WebGPU fp32, and KittenTTS generated playable WAV output locally.
