Materials will now be updated whenever possible instead of being recreated on every cook. This will significantly decrease HDA cook times for HDAs that import materials from Houdini. It will also prevent materials from being reset in the 3ds Max viewport.

The parameter user interface will now only update a parameter and cook the HDA if the parameter value has actually changed.

The attribute create and wedge TOP nodes will now issue a warning when they rename an attribute to make it a valid attrib name. An issue with the wedgeattribs attribute on wedge work items incorrectly storing invalid attribute names has also been fixed.

The TOP Deadline scheduler now supports work item export environment attributes. If the work item environment attribute contains PATH, it will override the local machine's PATH environment for the task.

Converting to and from LAB colorspace using ctransform will now correctly use the C reference white value. This means values may be different than before.

The Scene Import LOP now sets the "normalize" attribute on all created USD lights to "True", since this corresponds to how mantra treats lights created at the object level.

Improved performance of Edit Properties-based LOP nodes which create USD primitives. Also added explicit performance monitoring of copying USD layers within a cook, to help discover when the size of the active layer is a limiting factor in the performance of a LOP network.
