Exchange 2013 CU 10 and Enterprise Vault 10

I believe that the Exchange 2013 CU 10 certification is still pending for EV 10.0.4. 

And I wanted to know if anyone has already upgraded their Exchange to cummulative update 10,and is their anything that breaks as a consequence.

We are currently on Exch 2013 CU 8 and to complicate matters we are using a DAG over two nodes and so will at some point have them running at different versions.
