Full Release Notes

# RealtimeTTS v0.6.0

### Features

- **New TTS Engines**
  - **Faster Qwen3 TTS**: Added `FasterQwenEngine` engine. See tests/faster_qwen_emotions.py and tests/faster_qwen_test.py for details how to implement. Demo video: https://www.youtube.com/watch?v=ZOKcUpJlrXQ
  - **Cartesia**: Added engine for Cartesia speech synthesis via WebSocket API. ([#348])
  - **MiniMax Cloud TTS**: Added `MiniMaxEngine` for MiniMax T2A v2 API with 2 models (`speech-2.8-hd`, `speech-2.8-turbo`), 12 voice presets, and runtime parameter control. ([#369])
  - **ModelsLab TTS**: Added `ModelsLabEngine` supporting 30+ voices in 9 languages, speed and emotion control, and lazy loading. ([#368])
  - **CAMB AI MARS TTS**: Added `CambEngine` and `CambVoice` for CAMB AI's MARS models, supporting 140+ languages and streaming output. ([#367])
  - **NeuTTS**: Added `NeuTTSEngine` for on-device TTS with voice cloning (3s reference audio, CPU/CUDA/MPS support). ([#359])
  - **PocketTTS**: Added `PocketTTSEngine` for CPU-optimized TTS (Kyutai Labs, 8 voices, voice cloning, low latency). ([#358])

- **WebSocket Streaming**
  - Real-time TTS streaming via WebSocket endpoint with multi-user support, bidirectional audio, and enhanced web UI. Includes Python demo client. ([#356])

### Improvements

- **Engine Usability**
  - Allow `OpenAIEngine` to accept API key as parameter (fallback to env var). ([#361])
  - Add language parameter to `ZipvoiceEngine` for output and prompt speech. ([#362])
  - Add `mpv_audio_device` option to `AudioConfiguration`/`TextToAudioStream` for MPV playback device selection. ([#327])
  - Add adjustable volume parameter (0.0–1.0) to `TextToAudioStream`. ([#335])
  - PiperEngine: Streamline synthesis and add samplerate detection from model config for better quality with larger models. ([#346], [#347])
  - Conditional logging: Only print "SYNTHESIS FINISHED" if logging is enabled. ([#332])

- **General**
  - Install `portaudio` for MacOS. ([#328])

### Fixes

- Correct typo in `requirements.txt` for `pypinyin` version. ([#355])
- Fix missing comma in `__all__` that affected engine exports. ([#367])
- Add audio format detection/conversion for non-Kokoro TTS engines. ([#356])
- Fix voice retrieval errors and improve engine initialization logic. ([#356])

### Other

- Updated documentation for new engines, playback options, and WebSocket usage.
- Added/updated test files and demo scripts for new engines.
- No breaking changes; all updates are backward compatible.
