AI Summary

Fixes Apple Silicon compatibility by automatically selecting the GGML backend when CUDA is unavailable and standardizing the inclusion of the Metal runtime.

Key Highlights

  • CLI now selects GGML when CUDA is unavailable on Mac
  • Standard install includes Metal runtime
  • Explicit backend selection remains available
  • Supports macOS 14+ on ARM64 Python

New Features

  • Auto-selection of GGML backend on Apple Silicon
  • Metal runtime inclusion 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.
