Important: HandTracking Smoothing has been removed as smoothing is now done on the platform and no longer needed in the MRTK layer.

Added a Wireframe General Rendering option to the MagicLeap Spatial Mesh Observer.
Additional Logic to better support the "Air-Tap" Gesture.
Added Support for System Voice Commands in the Speech Input Profile Important: Scenes using Speech Commands will need to update their profiles from the DefaultmixedRealitySpeechCommandsProfile to the Magic Leap Speech profile located at Assets/Create/Mixed Reality/Toolkit/Profiles

Handtracking Performance issues when interacting with other objects. Continuous Improvements made each Sprint.
To use the simulator when running MRTK, you must set the Script Changes While Playing setting to Stop Playing and Recompile or Recompile and Continue Playing in the Unity Preferences.
The logs may show a single false Permission Denied error when running meshing.

Instead of copying a configuration file, clone the DefaultMixedReality version and make adjustments. We have found copying an MRTK configuration file can cause issues such as Input Data Providers not loading or visualizers not attaching properly.
Controller Visualizer sometimes stops positioning and the logs say: Left_ControllerModel(Clone) is missing a IMixedRealityControllerVisualizer component! This happens sporatically, we have found adding the MixedRealityControllerVisualizer component to the model itself resolves this.
If your application builds and results in a blank/empty scene, you must adjust your projects quality settings. (Known issue in editors 2021.1 and older) To resolve this, remove all but one of the quality presets in your projects quality settings (Edit>Player Settings>Quality).
Users may need to add the tracked pose driver to the camera themselves.
