The ComfyUI-RMBG background-removal/segmentation node pack shipped v3.2.0 with substantial updates.

Two new nodes

Model unloading: every node that loads a large model now has an optional unloadmodel toggle that frees VRAM immediately after the node finishes.

Fixes: transformers 4.x compatibility (5.0 broke RMBG-2.0, SAM, SAM2, GroundingDINO), batch dimension mismatches, SDMatte crashes on unmasked input, new SAM3 Multiplex support with native safetensors, a fix for Apple Silicon nodes silently falling back to CPU, and startup time cut from 15s to under 0.1s.
