 ### [Unreleased]
 
+### Added
+
+- A new `FSGDebugVirtualHand::Draw()` overload has been added to allow visualizing `FSGDebugGizmoSettings` directly. This is used internally by the new `USGHandTrackerComponent` to visualize its `FXRHandTrackingState` if `bVisualize` is enabled.
+
 ### Fixed
 
 - Fix some copyright notices with wrong copyright owner. These propably has happend during bulk replaces with class or struct names.

 ### Changed
 
 - List existing SenseGlove components under `SenseGlove` `ClassGroup` inside Unreal's Blueprint Editor. This chagnes `ClassGroup` for `USGGrabComponent`, `USGTouchComponent`, `USGVirtualHandComponent`, and `USGWristTrackerComponent`.
-- Force `USGVirtualHandComponent` and `USGWristTrackerComponent` to update their XR hand-tracking state when their handedness is updated.
+- Force `USGVirtualHandComponent` and `USGWristTrackerComponent` to update their XR hand-tracking data when their handedness is updated.
 - Bumped the SenseGlove Unreal Engine Marketplace Packager to `v0.6.1-85c5a6e`.
 - Bumped the copyright years.
