Max 2017 new viewport features documentation

Looking for some hard documentation (help file or other) on the new viewport features introduced in Max 2017. These include the "quality" viewport label menu and new "viewport preferences and settings" dialog. I have not been able to locate anything about them in the 2017 help file or, more to my needs, the MaxScript help. Has anyone located documentation on these features other than the online videos? Any links, info or recommendations would be welcome!
Specifically, I have a script that controls my viewports and need to adapt it for 2017. Some things can be accomplished using the ActionManager as shown with the MacroRecorder but this is not ideal and I find it hard to believe there is no MaxScript access to these features.
