-This new version upgrades from Unity 5.5.1 to the latest 5.5.2 and introduces multithreaded rendering for faster performance (higher frame rates) on multi-core CPUs.
-The patch before this had a second camera in the scene which was intended for the Vive. The camera was supposed to be destroyed if you were not running VR, but mistakenly was left in the scene. This too was slowing down rendering performance when VR was not being used. This has been fixed, so performance might be significantly improved between this and the new multithreaded rendering.
-The foam cutting across the water when you first get to or reset a water scene has been fixed.
