Scripted Renders - What Versions of 3Delight and Renderman does Daz Use?

Hello all,

I started looking into scripted rendering for 3Delight and I see in the Daz Scripting Documentation for the DzScriptedRenderer is says "Implements a scriptable RenderMan interface for the scene to render itself through the 3Delight renderer."

http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/scripting/api_reference/object_index/scriptedrenderer_dz

And then for the methods referenced points to a RenderMan 20 doc at (example for RiOption()): https://renderman.pixar.com/resources/RenderMan_20/options.html#rioption

What I don't see is what version of 3Delight does Daz use and does that version support all the features in the RenderMan 20 docs?

thanks
