com.unity.xr.meta-openxr 2.1.0-pre.1 Package Notes

Added a validation rule to warn you that soft shadows can negatively affect performance for Meta Quest.
Added Scene setup documentation to clarify best practices for requesting Android system permissions.
Added support for running scenes in the editor via [Quest Link](xref:meta-openxr-link).
Added a public class [MetaOpenXRFeature](xref:UnityEngine.XR.OpenXR.Features.Meta.MetaOpenXRFeature) as the new base class for OpenXR features in this package.
Added the Meta Quest Boundary Visibility feature, which enables you to suppress the visibility of the boundary so users can move freely with Passthrough enabled. Refer to [Boundary visibility](xref:meta-openxr-boundary-visibility) for more information.
Added support for [Occlusion](xref:meta-openxr-occlusion).

Changed the **Meta Quest: Bounding boxes**, **Meta Quest: Anchors**, **Meta Quest: Meshing**, and **Meta Quest: Planes** features implementation to replace the use of `XR_FB_spatial_entity_query` and `XR_FB_spatial_entity_storage` with newer OpenXR extensions from Meta. This is a backwards-compatible change with no effect on your code.
Changed the **Meta Quest: Camera (Passthrough)** feature to no longer enable the `XR_FB_composition_layer_alpha_blend` OpenXR extension. This is a backwards-compatible change with no effect on your code.
Changed the severity level of validation rules for features that depend on **Meta Quest: Session** from Warning to Error. These features are unusable at runtime if **Meta Quest: Session** is not enabled, so Error is the appropriate severity level for the validation rules.
Changed the dependency version of XR Core Utilities from 2.4.0 to 2.5.1.

Removed a validation rule that warned you if your currently open scene did not have an `ARCameraManager` component while the **Meta Quest: Camera (Passthrough)** feature was enabled. Too often this warning was a false positive for valid project setups, so it wasn't helpful.

Fixed an issue with [BoundedPlane.nativePtr](xref:UnityEngine.XR.ARSubsystems.BoundedPlane.nativePtr), [XRBoundingBox.nativePtr](xref:UnityEngine.XR.ARSubsystems.XRBoundingBox.nativePtr), and [XRAnchor.nativePtr](xref:UnityEngine.XR.ARSubsystems.XRAnchor.nativePtr) so they now return a pointer to a struct with a version number and a pointer to the `XrSpace` handle of their respective trackable type. Refer to [Plane native pointer](xref:meta-openxr-planes#Native-pointer), [Bounding box native pointer](xref:meta-openxr-bounding-boxes#Native-pointer), and [Anchor native pointer](xref:meta-openxr-anchors#Native-pointer) for more information.
Fixed Android Manifest setup for builds so that if your app uses Bounding Boxes or Meshing but not Planes, your app's Android Manifest will now correctly declare the `com.oculus.permission.USE_SCENE` permission.
Fixed the **Meta Quest: Display Utilities** feature so that it works correctly even when **Meta Quest: Session** is disabled. (MOXRB-70)
Fixed the **Meta Quest: Anchors** and **Meta Quest: Passthrough** features so they gracefully fail to create their subsystems if the OpenXR runtime does not support the required system properties.
