Breaking Changes

●Issue #1

Removed unsafe pickle loading code that was used for older PyTorch versions (older than 2.4). If you are using PyTorch < 2.4, you may encounter issues.

●Issue #2

Removed workaround code that supported RMSNorm on old PyTorch versions.

Migration Steps

  1. 1
    If you rely on pickle loading for PyTorch versions older than 2.4, you must update your PyTorch installation.
  2. 2
    If you were using the "gpt-4o" model in API Nodes, you must select an alternative model.

Release Summary

This release introduces significant feature additions like the VideoSlice node, enhanced ControlNet support (Qwen 2512), and new API nodes for 3D and image background removal. It also includes numerous stability improvements, especially around dynamic VRAM management, training, and fixing issues with older PyTorch compatibility.
