Breaking Changes

●Issue #1

The dependency on the 'soundfile' package has been removed, as torchaudio load or save operations are no longer used for audio handling. If your workflow relied on 'soundfile' directly, you may need to adjust your setup.

Migration Steps

  1. 1
    If you were using 'soundfile' directly for audio operations, you must now use alternative methods as it has been removed as a dependency.
  2. 2
    Users on AMD systems should review the updated instructions in the readme for installing nightly PyTorch builds and using the new .bat file to disable smart memory if necessary.

Release Summary

This release focuses heavily on migrating existing nodes to the V3 schema, introduces support for the hunyuan vae, and includes several bug fixes related to VRAM leaks and API nodes. The 'soundfile' dependency has also been removed.
