Thanks in general for you reply t.petrov. I have a couple of further questions.
Would it be possible to get some notes (when its released) that specifies which features are missing in comparison to the nightlies?
Ive downloaded the vray_adv_23002_maya2011_x64 (we currently run most of our productions in 2011) installer from the downloads section.
At a glance I cant see any changelog in there at all. The Zip install doesnt contain anything either.
Is it part of the actual windows installer?
Fair enough 
I will script myself out of it, was just wondering.
Btw, as a sidenote. Would it be possible to get the nightly builds also just as a simple zip(instead of a windows installer).
We tend to not install vray strait on the machine and instead use environment variables to control the installation location (on the server or whatever).
The official releases have a nice little zip file with all the files needed and that one is much easier to deploy for us (instead of making a local install and then stripping out the needed files).
