Exchange 2010 Sp3 AD Schema Changes

I am looking for a listing of Active Directory Schema Updates that Exchange 2010 SP3 makes.  We are currently on SP1, and we will most likely end up at SP2 RU6, but if the changes are minimal to SP3, we may go ahead and extend the AD Schema to SP3 just so we don't need to involve the AD Team again.  Does anyone know where to find a complete list of AD Schema updates from Exchange 2010 SP3? I've checked:

Exchange Server changes to the Active Directory Schema webpage, but it does not have SP3, only Sp2.

Any help would be GREATLY appreciated.

Thanks!
