Key Highlights
- GGML CLI works by default on supported Mac
- Standard install includes Metal runtime on Apple Silicon
- CUDA hosts still default to Torch backend
- Explicit backend selection remains available
New Features
- Automatic backend selection on Mac
- Inclusion of Metal runtime in standard install
Full Release Notes
## Fixes - The CLI now selects GGML when CUDA is unavailable, so `faster-qwen3-tts custom ...` works on a supported Mac without `--backend ggml`. CUDA hosts still default to the Torch backend; explicit backend selection remains available. - A standard install on native Apple Silicon now includes `qwentts-cpp-python>=0.4.1` and its Metal runtime. Other platforms still use the optional `ggml` extra. Upgrade with `uv pip install -U faster-qwen3-tts`. The Metal wheel supports macOS 14+ on ARM64 Python; Intel Macs and Rosetta Python are outside its supported platforms. ## Changes - [Make Apple Silicon GGML CLI work by default](https://github.com/andimarafioti/faster-qwen3-tts/pull/140) - [Prepare release 0.5.1](https://github.com/andimarafioti/faster-qwen3-tts/pull/141) [Full changelog](https://github.com/andimarafioti/faster-qwen3-tts/compare/v0.5.0...v0.5.1)
