com.unity.xr.hands 1.5.0 Package Notes

Added `XRCommonHandGestures` and surfaced related data from the OpenXR Hand Interaction Profile extension.
Added public `subsystem` property to `XRHandTrackingEvents` to let users get the `XRHandSubsystem` that is the source of the hand tracking data. Also added public `subsystem` property to `XRHandJointsUpdatedEventArgs` so it is available in the `XRHandTrackingEvents.jointsUpdated` event callback.
Added support for a new `XRHandJointTrackingState.HighFidelityPose` flag to the XR Hands Subsystem.
- Added support for the HighFidelityPose tracking flag to the OpenXRHandProvider.
- Updated hand visualization sample to color debug joint cubes based on tracking fidelity: opaque white for joints which have a pose and are high fidelity; translucent red for joints which have a pose and are not high fidelity.
Added OpenXR callbacks `HandTracking.subsystemCreated` and `HandTracking.destroyingSubsystem` for lifecycle response.
Added OpenXR APIs `HandTracking.automaticallyInitializeSubsystem` and `HandTracking.EnsureSubsystemInitialized` to allow for delayed initialization of the `XRHandSubsystem`. To disable automatic creation in time, set `HandTracking.automaticallyInitializeSubsystem` to `false` in a `static` method decorated with `[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.SubsystemRegistration)]`, then call `HandTracking.EnsureSubsystemInitialized` when ready.

Allows for ignoring tip-most knuckle when calculating full curl when the `XRFingerShapeConfiguration`'s `minimumFullCurlDegrees3` or `maximumFullCurlDegrees3` is non-positive.

Fixed reference direction when using `XRHandUserRelativeDirection.NoseDirection` for gesture detection.
Fixed runtime invalidation, which resulted in crashes on some OpenXR runtimes. Runtime is invalidated when the `XrInstance` is destroyed.
Fixed threshold-checking on gesture conditions to allow for the full range in `XRFingerShapeCondition`.
`XRCommonHandGestures` data retrieval no longer GC.Allocs.
Updated app space change behavior for XR provider to no longer destroy hand trackers only to recreate them the next update.
Fixed issue where XrHands would try to update hand joints with an uninitialized XrTime value of XR\_INFINITE\_DURATION.
Fixed an issue with packaging that prevented MacOS compatible libraries from being included as part of the package.
