# OpenVR SDK 1.26.7

IVROverlay:
* Removed defunct GetOverlayTransformOverlayRelative and SetOverlayTransformOverlayRelative interfaces

EVREventType:
* Removed defunct VREvent_SceneFocusChanged

ETrackedDeviceProperty:
* Added Prop_Hmd_SupportsHDR10_Bool
* Added Prop_Hmd_EnableParallelRenderCameras_Bool (drivers can set this compensate for canted and/or clocked displays)
* Added Prop_DriverProvidedChaperoneJson_String (overrides Prop_DriverProvidedChaperonePath_String)
* Renamed Prop_Hmd_SupportsRoomViewDirect_Bool
* Renamed Prop_Hmd_SupportsAppThrottling_Bool
* Added Prop_Hmd_SupportsGpuBusMonitoring_Bool
* Added Prop_DSCVersion_Int32
* Added Prop_DSCSliceCount_Int32
* Added Prop_DSCBPPx16_Int32

VROverlayTransformType:
* Removed defunct VROverlayTransform_SystemOverlay
* Added VROverlayTransform_Subview

Compositor_CumulativeStats:
* Added m_nNumFrameSubmits
* Added m_flSumCompositorCPUTimeMS
* Added m_flSumCompositorGPUTimeMS
