The SQL Server team has released CU #10 for SQL Server 2012 RTM.
For most customers, this cumulative update hardly justifies the download, never mind patching and regression testing, at least IMHO. Of the four fixes, two involve SSAS, one involves SSRS, and one involves the database engine tuning advisor.
NOTE: In December, we will see CU #11 for SQL Server 2012 RTM. This will be THE LAST CU for the RTM branch. This should tell you two things: (1) SP2 is very likely on its way soon, and (2) if you're still on RTM, it's getting time to think about moving to SP1 (or SP2, when it arrives).
Relevant for builds 11.0.2100 -> 11.0.2419. Do not attempt to install on SQL Server 2012 SP1 (any build >= 11.0.3000) or any previous version.
