Microsoft has released SQL Server 2012 Service Pack 1 CU12 (Build 11.0.3470) and SQL Server 2012 Service Pack 2 CU2 (Build 11.0.5548). Both of these CUs (which were released on the same day) have a significant number of valuable hotfixes. SP1 CU12 has 14 hotfixes, and SP2 CU2 has 50 hotfixes.

Needless to say, I think you should be planning on getting to the SQL Server 2012 SP2 branch if you are not already there. You should not just go to SP2 RTM (Build 11.0.5058), but all the way to SP2 CU2.

I am hoping that more and more of the CU-averse individuals and organizations will be convinced to start to install SQL Server Cumulative Updates after seeing this new Microsoft KB article:
