 ## [Unreleased]
 
+### Fixed
+- Added missing script and gizmo icon for `TrackedPoseDriver.cs` component ([case ISXB-262](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-262)).
 - Fix for mitigating symptoms reported in ([case UUM-10774](https://issuetracker.unity3d.com/product/unity/issues/guid/UUM-10774) effectively avoiding reenabling mouse, pen or touch devices in `InputSystemPlugin.OnDestroy()` if currently quitting the editor. The fix avoids editor crashing if closed when Simulator Window is open. Note that the actual issue needs a separate fix in Unity and this package fix is only to avoid running into the issue.
 - Fixed an issue where Input Action name would not display correctly in Inspector if serialized as `[SerializedProperty]` within a class not derived from `MonoBehavior` ([case ISXB-124](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-124).
 - Fix an issue where users could end up with the wrong device assignments when using the InputUser API directly and removing a user ([case ISXB-274](https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-231)).
