Today Microsoft called me with the news that Cumulative Update 2 (CU2) for ConfigMgr 2012 R2 SP1 and 2012 SP2 is released. This because I had some issues at customer location with Intune extensions not working in a hybrid ConfigMgr environment. With CU2 those issues must be gone now! KB3100144 (CU2) solves a lot of issues and is therefore highly recommended. It contains 34 (!) fixes and improvements and some additional changes too.
More about that can be found in another blogpost. No need to install KB3074857 (CU1) anymore after installation. This because it's integrated in CU2 now.
During installation (which is default as always) update packages will be created for site servers, ConfigMgr consoles and clients. When having Intune integrated in ConfigMgr (hybrid configuration), extensions will be updated as well. Great that CU2 is available now, and hope that ConfigMgr vNext will released soon too.
After installation you will see Console version 5.0.8239.1301 now, which is the latest release. Just install it in your environment when experiencing problems described in this article. When not affected by these problems, Microsoft recommends to wait for the next service pack that contains this update.
Update: There was a minor bug in the first CU2 release. The product group has released a new build now. If you are installing using the new build, the console version will be 5.0.8239.1302
