+# Custom Hires Fix (webui Extension)
+## Webui Extension for customizing highres fix and improve details (currently separated from original highres fix)
+
+
+#### Update 16.10.23:
+- added ControlNet support: choose preprocessor/model in CN settings, but don't enable unit
+- added Lora support: put Lora in extension prompt to enable Lora only for upscaling, put Lora in negative prompt to disable active Lora
+
+#### Update 02.07.23:
+- code rewritten again
+- simplified settings
+- fixed batch generation and image saving
+
+#### Update 13.06.23:
+- added gaussian noise instead of random
+
+#### Update 29.05.23:
+- added ToMe optomization in second pass, latest Auto1111 update required, controlled via "Token merging ratio for high-res pass" in settings
+- added "Sharp" setting, should be used only with "Smoothness" if image is too blurry
+
+#### Update 12.05.23:
+- added smoothness for negative, completely fix ghosting/smears/dirt on flat colors with high denoising
+
+#### Update 02.04.23:
+ ###### Don't forget to clear ui-config.json!
+- upscale separated from original high-res fix
+- now works with img2img
+- many fixes
+
