gridsize setting has been removed from the PrmanGlobalStatements node.
All displays that are using the channel "rgba" in the RenderOutputDefine node now use "Ci" for live and preview renders. This should remove this warning: R09025 {WARNING} Additional display cannot be mode rgba.
DeepEXR displays now use "Ci,a" rather than "Ci" to conform with the DeepEXR specification. RfK will automatically generate the Ci and a DisplayChannels for deepexr if they are not manually created.

Using a CameraImagePlaneCreate node to view a textured image plane no longer breaks textured light visualization in the Viewer.
Fixed a Katana crash when viewing a light with a 16k texture.
Fixed 'Error: Subdivide failed at 'unknown scenegraph location' that could appear on pruned scenegraph locations.

Light linking edits are not currently supported.
Lights can be added during live rendering however, due to a bug in Katana 2.1, a newly-added light is not automatically 'live' and does not inherit its live state from the parent. When adding a light you will need to manually activate that light in the Scene Graph. Newly added lights work correctly in Katana 2.0 and Katana 2.5v5+.
Adding mesh lights during live rendering creates duplicate geometry, upon re-render this is solved.
Changes to light filters are not processed unless the associated lights are also marked 'live'.
Alembic geometry mesh light transform edits (i.e. Transform3D changes) are not updated correctly during live rendering.
Muting a PxrDomeLight with PxrPortalLight children does not successfully mute the portal lights.
"Disable Local Assignment" does not work during live rendering with parameters of OSL shaders (e.g. PxrLayer and PxrLayerMixer).
Disabling and re-enabling layers in PxrLayerMixer can cause instability in Live Rendering.
Texture changes are not currently supported during live rendering.

If an object is assigned a material that has been disabled or does not exist the geometry will not render at all.
If you are rendering to 'it' the Monitor tab must be open for the Render Log tab to receive output from Katana and prman.
Although direct non-identity scaling has been removed from the PxrDomeLight and PxrDistantLight it is still possible to get an indirect scale via a constrained or inherited location. If the indirect scale is negative the Pxr light will flip to a reverse orientation.
Bake renders only work as Disk Renders. The render will fail for Live and Preview Renders.
