AI Summary

This release adds significant performance and usability improvements including CPU MPS support, SafeTensors model format migration, optional Classifier-Free Guidance, and Min_P sampler support. The release also includes bug fixes, updated example scripts with sample audio files, and documentation improvements.

Key Highlights

  • Added CPU MPS (Metal Performance Shaders) support for Apple Silicon Macs
  • Migrated models from PyTorch (.pt) to SafeTensors format for better performance and security
  • Made Classifier-Free Guidance (CFG) optional, giving users more control over inference
  • Added Min_P Sampler support with modified sampler settings
  • Fixed CUDA error #72 and updated example scripts with sample wavs and watermarking info

Breaking Changes

  • Model format changed from .pt to .safetensors - existing .pt models may need to be re-converted

New Features

  • CPU MPS support for Apple Silicon Macs
  • SafeTensors model format support
  • Optional Classifier-Free Guidance (CFG)
  • Min_P Sampler and configurable sampler settings
  • Updated example scripts with sample audio files
  • Watermarking information and documentation
  • Clarified OS and Python version requirements
  • Adjusted dependencies
