 - Text on the toggle button in the UI Input example scene now shows On or Off based on the toggled state
 - Clients were not able to subscribe to the events on the PinchDetector and GrabDetector scripts as the properties were exposed as readonly. 
 - GrabDetector detection logic was inverted, so open hands were interpreted as grabs. Now fixed.
+- Fixed issue with scale of outline in GenericHandShader if hand model normals are not a normalized length 
 
 ### Known Issues
 - Pose detection scene does not illuminate all poses in green if built for mobile headsets when using URP (2022.3), spotlights don't work as intended on Unity 6.
