 - New error and exception handlers

 - Enhanced environment tuning  
+- Optimized startup and models lazy-loading  
+- Built-in performance profiler  
 - Updated libraries to latest known compatible versions  
 - Includes opinionated **System** and **Options** configuration  
 - Does not rely on `Accelerate` as it only affects distributed systems

   Gradio web server will be initialized much earlier which model load is done in the background  
   Faster model loading plus ability to fallback on corrupt models

 - Majority of settings configurable via UI without the need for command line flags

-### User Interface
-
-- Includes updated **UI**: reskinned and reorganized  
-  Black and orange dark theme with fixed width options panels and larger previews  
-
 ### Optimizations
 
 - Optimized for `Torch` 2.0  
 - Runs with `SDP` memory attention enabled by default if supported by system  
+  *Note*: `xFormers` and other cross-optimization methods are still available  
 - Auto-adjust parameters when running on **CPU** or **CUDA**  
   *Note:* AMD and M1 platforms are supported, but without out-of-the-box optimizations

-
-- Drops compatibility with older versions of `python` and requires **3.9** or **3.10**  
-- Drops localizations  
-- Drops automated tests
