- Added events (VREvent_TrackedDeviceUserInteractionStarted and VREvent_TrackedDeviceUserInteractionEnded) and a new interface method (IVRSystem:: GetTrackedDeviceActivityLevel) to hint an application about whether a device is being held or worn by a user.
- Added events (VREvent_FocusEnter and VREvent_FocusLeave). These are sent to overlays with automatic mouse processing when the cursor moves onto or off of an overlay. Use them to clean up hover states in your overlay UI.
- Dashboard overlays will now be send pressed and unpressed events when they are the current overlay.
- Added IVRSystem::GetRawZeroPoseToStandingAbsoluteTrackingPose(), which allows an application to transform between standing and the raw coordinate system.
- Added method (IVRChaperone::SetSceneColor) to let the app provide a hint to the compositor about the scene color so it can pick reasonable bounds colors.
- Added methods to (GetBoundsColor, AreBoundsVisible, ForceBoundsVisible) to let applications query the current state of the bounds.
- IVRCompositor::Submit now takes a flag parameter that allows an application to submit images that have already been distorted.
- Added methods (SetSkyboxOverride and ClearSkyboxOverride) to IVRCompositor to allow applications to control the skybox that will be visible when the compositor draws. This is useful for when an application knows it is not going to render for a while (because it is loading a level or doing some other blocking action.)
