-  (production remains on torch2.0.1+cuda11.8)
+  (production remains on torch2.0.1+cuda11.8)  
 - fully extend support of `--data-dir`  
-  allows multiple installations to share pretty much everything, not just models
-- add dark/light theme mode toggle
-- redo some `clip-skip` functionality
-- better matching for vae vs model
-- update to `xyz grid` to allow creation of large number of images without
-- fixes...amazing how many issues were introduced by porting new a1111 code without adding almost no new functionality
+  allows multiple installations to share pretty much everything, not just models  
+- redo api authentication  
+  now api authentication will use same user/pwd (if specified) for ui and strictly enforce it using httpbasicauth  
+  new authentication is also fully supported in combination with ssl for both sync and async calls  
+  if you want to use api programatically, see examples in `cli/sdapi.py`  
+- add dark/light theme mode toggle  
+- redo some `clip-skip` functionality  
+- better matching for vae vs model  
+- update to `xyz grid` to allow creation of large number of images without  
+- update `gradio` (again)  
+- more prompt parser optimizations  
+- better error handling when importing image settings which are not compatible with current install  
+  for example, when upscaler or sampler originally used is not available  
+- fixes...amazing how many issues were introduced by porting new a1111 code without adding almost no new functionality
