    (internal MR 2549)
  • New vendor extension: XR_ML_spatial_anchors
    (internal MR 2803)

    (internal MR 2804)
  • New vendor extension: XR_ML_system_notifications
    (internal MR 2946)
  • New vendor extension: XR_ML_world_mesh_detection
    (internal MR 2950)
  • New vendor extension: XR_ML_view_configuration_depth_range_change
    (internal MR 3036)
• Specification
  • New vendor extension specification: XR_HTC_body_tracking provides an
    interface for full-body joint tracking.
    (internal MR 2549)
  • New vendor extension specification: XR_ML_spatial_anchors introduces an API
    to interact with Magic Leap spatial anchors.
    (internal MR 2803)
  • New vendor extension specification: XR_ML_spatial_anchors_storage allows for

    (internal MR 2804)
  • New vendor extension specification: XR_ML_system_notifications provides
    control over suppressing system notifications.
    (internal MR 2946)
  • New vendor extension specification: XR_ML_world_mesh_detection provides
    access to a world mesh.
    (internal MR 2950)
  • New vendor extension specification:
    XR_ML_view_configuration_depth_range_change permits the clipping planes to be
    changed by the runtime during the lifetime of an instance.
    (internal MR 3036)
  • Fix: Corrected swapchain image layout requirements for XR_KHR_D3D12_enable,
    XR_KHR_vulkan_enable, and XR_KHR_vulkan_enable2 so that the runtime's
    guarantees are made after xrWaitSwapchainImage returns XR_SUCCESS, instead
    of after xrAcquireSwapchainImage. (Queue access rules are unchanged.)
    (internal MR 3353,
    internal issue 2269)
