The System Center Config Mgr 2012 MP has been updated.
Unfortunately – it is undocumented what was changed from the previous release. 
We can make some guesses, however from the supported configurations page in the guide:
|
Configuration |
Support |
|
System Center 2012 Configuration Manager Service Pack (SP2) CU3 or later version |
Yes |
|
System Center 2012 R2 Configuration Manager CU3 or later version |
Yes |
|
System Center Configuration Manager 1602 or Later |
Yes |
|
Configuration Manager 2007 |
Not supported |
The previous ConfigMgr 2012 MP supported SCCM 2012, and SCCM 2012 SP1. It was never updated for SCCM 2012 SP2 or SCCM 2012R2…. but it worked for those versions.
However – this new MP now explicitly states support for:
- SCCM 2012 SP2 CU3+
- SCCM 2012 R2 CU3+
- SCCM build 1602+
