Thanks for the information Werner. 
Currently we have planned to install DS4.0, but I went thru the link https://bobj-board.org/t/165271 where you have posted that only for the customers nominated for 4.0, will be given the installation. My question here is, has DS4.0 released? cos u had mentioned it will be released around December. If not, I will have to nominate to get it?
My other doubt is, our test and production environments run on Unix solaris server. Will 4.0 install in them without any issues?
