  • More sample scenes from MRTK2. (11710, 11733, 11734, 11736, 11740, 11744, 11748)

Changed

  • MRTK3 now requires com.unity.inputsystem version 1.6.1 to address mouse input issues on HoloLens. (11661)
  • The CameraSettingsManager component is now on the MRTK XR Rig prefab. This component auto configures the main camera's settings based on the device's display type (Transparent or Opaque). (11684, 11685)
  • Refactored duplicate LocateTargetHitPoint methods to a common, shared location. (11699)
  • Moved some misplaced control prefabs to proper directories. (11707)
  • The UnboundedTrackingMode component was added to the MRTK XR Rig prefab. This change only impacts HoloLens 2 applications. (11750)
  • Changed how applications can create custom reticles in MRTK3. It should be easier now. (11758, 9)
  • All namespaces have had Microsoft removed, so to align with new MRTK organization. (1)
  • MRTK3 is now licensed under BSD 3-Clause. (2, 30)

Deprecated

  • The com.microsoft.* packages are now deprecated. Switch to the org.mixedrealitytoolkit.* packages instead. (#31, #32, #34)

Removed

  • Removed the SpatializationMixer property from MRTK3 settings. This property wasn't used in the MRTK3 packages, so was removed for now. This property can be added later, once it has a well-defined use within the MRTK3 packages. (11681, 11694)
  • Removed IVariableReticle and replaced with IReticleVisual and IVariableProgressReticle. Depending on the scenario, applications should implement one or both of the new interfaces. (11758, 9)
