Question for Theta Casablanca II configurations...

I planning for purchasing a pre-owned CBII, questions are:
Casablanca II -
1. Does it able to decode DTS ES, DD EX or even PLIIx for a 7.1 speaker setup?
2. does it require certain software version and is it free to get and upgrade my myself? There are no release notes on theta download site, but a latest software is available there, wonder if all CBII no matter what firmware can be upgraded?
p.s. I have extreme card, and 2 x superior card with L/R/C/SR/SL/SUB
