I don't know of any updates but Microsoft can always change the exams without any further information. So I would always check the changes and make sure to know what was changed.
I just want to refer to all the confusion regarding the Windows Server 2008 exams which got updated to R2 with a deep impact (!!) to the exam and it took quite long till the changes was confirmed by different Microsoft employees (I think the thread can easily
be found. I think it was the 70-640 exam. Just search for some big threads with 40+ posts on that topic!)
With kind regards,
Konrad
