 ## Change history
 
+* 12/18 (v18.1) update:
+    - Add Stable Diffusion model conversion utility. Make sure to run `pip upgrade -U -r requirements.txt` after updating to this release as this introduce new pip requirements.
 * 12/17 (v18) update:
     - Save model as option added to train_db_fixed.py
     - Save model as option added to GUI
