dcs puccini software upgrade

hi. i am a puccini owner and believe that "newer" is not always "better." for this reason i haven't installed the new software. forgive me if i have missed this in a prior thread but has anyone either: (1) had a chance to compare the puccini, pre- and post- software upgrade, if so how does it sound? Or (2) know where the details of the software upgrade are outlined? (couldn't find it on dcs website)

thank you and best wishes!
