 - **v0.42**: Better README with category nodes, changes some node titles
 - **v0.43**: Add control_after_generate to Ollama and allow to keep in VRAM for 1 minute if needed. (For chaining quick generations.) Add fallback to 0.0.0.0
+- **v0.44**: Allow ollama to have a cusom url in the file `ollama_ip.txt` in the comfyui custom nodes folder. Minor changes, add details/updates to README.

 When you use `combine image` node, you can actually also send many images at once, it will combine them all.  
 Here is an example with `Load images from folder` node, `Image details` node and `Combine images` node. (Of course it can't have `all_in_one` set to True in this situation because the images have different resolutions) :
