Breaking Changes

●Issue #1

Custom nodes can no longer accidentally overwrite global modules. If a custom node relied on overwriting a global module, it must be refactored to use local imports or other isolation techniques.

Migration Steps

  1. 1
    If you were relying on custom nodes overwriting global modules, refactor those custom nodes.
  2. 2
    If using InputTypeOptions, stop using InputTypeOptions.defaultInput and update usage accordingly.

Release Summary

This release introduces significant new model support, including HiDream and Wan variants, alongside performance optimizations like MLU memory optimization and Dependency Aware Node Caching. It also deprecates an old input option and enhances node isolation security.
