What changed

  • Local model support: Fibo 2.0 image generation (with a fix for text-to-image negative prompts), MOSS-Image edit LoRAs, colour-depth control, attention bias conditioning, rope scaling and a model-specific merge node.
  • New core nodes: a Branch node, and a Pad Image node with mirror padding and padding to a multiple; ACEScg is added to Convert Image Color Space and the advanced EXR Save Image node.
  • New partner (API) nodes include Kling 4.0, FLUX 3 Max plus 2K and 4K FLUX 3 Video resolutions, PixVerse V6-Max, Ideogram Vector Generate SVG, HeyGen voice cloning and text-to-speech, and Mirelo SFX; partner-node sign-in tokens are now renewed and the client respects proxy environment variables.
  • Hardware and performance: PyTorch attention is enabled in the VAE on AMD, it is not used for head dimensions above 256 on gfx11, and the notes list Qwen 3.x speed work (adaptive tree MTP) and the first part of dynamic VRAM KV caches.
  • Fixes include a corrected top-p sampling threshold, Gemma 4 31B global attention, and a minimum Pillow version in the requirements.

What we have not verified

  • We did not run this release or any of the new nodes.
  • Partner nodes call paid third-party APIs; the release notes do not list their prices.
  • Performance changes are described only by pull request titles; we did not measure them.
