Summary

This release introduces initial support for the ACE-Step model, improves memory estimation for LTXV models, and resolves several bugs related to ACE functionality and character encoding. Torchaudio is no longer a hard dependency.

⚠️ Breaking Changes

  • Loading of api nodes will fail if the installed pyav version is too old. Users must update pyav to a compatible version to continue using api nodes.

Migration Steps

  1. Ensure your pyav installation is up-to-date to prevent failures when loading api nodes.

✨ New Features

  • Implemented initial ACE-Step model support.
  • Added experimental lyrics strength control for ACE features.
  • Improved detection logic to allow ltxv models without configuration files to load.

🐛 Bug Fixes

  • Fixed an issue where chroma was using an incorrect shift; now uses Flux shift.
  • Improved memory estimation specifically for the LTXV 13B model.
  • Adjusted memory estimation code to correctly handle ACE VAE.
  • Ensured Japanese hiragana and katakana characters function correctly with ACE.
  • Fixed an issue preventing ACE VAE tiling from working.
