Root primitive supported in MayaUSD exports : When you export with MayaUSD, if you set a root primitive then that is taken into account for Arnold nodes (such as lights). MTOA-2067
Windows MSI to have the same naming conventions as other installers : The Windows MSI installer now has the same formatting as the other installers, including the operating system in the file name (MTOA-2261)
Arnold RenderView OpenColorIO updated to 2.4.1 : Arnold RenderView (ARV) now uses OpenColorIO version 2.4.1

The attribute aiHydra in the Arnold section of the mayaUSD proxy shapes was replaced with aiLegacyTranslation. Setting it to off triggers the hydra mode of the usd procedural (MTOA-2262)
Ass file exports are now always exported using the internal Maya internal units of centimeters. Units are now also correctly taken in to account when loading ass files created in other Arnold plugins into aiStandIn nodes.This can affect the look of some shader networks as they now will match the shading in scenes with different units.
