Added new values to the BoundingBoxClassifications enum: Keyboard, Mouse, and Laptop.
Added constructors and defaultValue properties to XRSaveAnchorResult, XRLoadAnchorResult, and XREraseAnchorResult structs.
Added a constructor to Result<T> that enables more convenient construction of successful results.
Added a parentId property to ARTrackable with a public getter.
Added conversion operators between XRResultStatus and the new OpenXRResultStatus type introduced in OpenXR Plug-in 1.16.0-pre.1.
Added a new enum member XRResultStatus.StatusCode.Unsupported.
Added a constructor to XRAnchor that allows you to initialize all the struct fields.
Added XRAnchorBuilder, which provides a fluent API for constructing XRAnchor instances.
Added a constructor to TrackableChanges<T> that allows you construct an instance given IEnumerable<T> input collections.

Changed ARRaycastManager to always support physics-based ray casts as a fallback implementation, even if the provider doesn't implement the XRRaycastSubsystem. For more information, refer to Fallback ray casts.

Changed how trackable GameObjects are spawned to support parent-child hierarchies of any depth, allowing trackable GameObjects to have other trackable GameObjects as their parent.
