### Added
1212
- Experimental Meta compatibility mode for the OpenXR provider
1313
- Added support to upgrade the plugin's Built In Render Pipeline materials (and as a result the example scenes) to the Universal Render Pipeline. This can be set to automatically prompt when the materials don't match the current render pipeline. It does not support downgrading.

- Changed LeapC PInvoke signatures to support iOS

### Changed
1617
- Removed warning suggesting use of both input systems for OpenXR + Ultraleap compatibility now the new input system is fully supported
