 - **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.
 - **v0.45**: Add a new node : Text scrambler (Character), change text randomly using the file `scrambler/scrambler_character.json` in the comfyui custom nodes folder.
 - **v0.46**: ❗ A lot of changes to Video nodes. Save to video is now using FLOAT for fps, not INT. (A lot of other custom nodes do that as well...) Add node to preview video, add node to convert a video path to a list of images. add node to convert a list of images to a temporary video + video_path. add node to synchronize duration of audio with video. (useful for MuseTalk) change TTS node with many new outputs ("audio_path", "full_path", "duration") to reuse with other nodes like MuseTalk, also TTS rename input to "connect_to_workflow", to avoid mistakes sending text to it.
+- **v0.47**: New node : Loop Load checkpoint (Model Selector).

+**Description:**  
+This is the loop version of node 41. (check there for similar details)  
+It will loop over all the selected checkpoints.  
+
+❗ The big difference with 41 is that checkpoints are preloaded in memory. You can run them all faster all at once.  
+It is a good way to test multiple checkpoints quickly.
