RBA Viewer from the toolkit no longer opens after the application of CU1 for SCCM 2012 R2 SP1. I show this VERY useful tool to almost every customer of mine as most of them struggle with creation of roles correctly. The viewer crashes with the following message in the debug.
Updated toolkit is here: http://download.microsoft.com/download/5/0/8/508918E1-3627-4383-B7D8-AA07B3490D21/ConfigMgrTools.msi

This seems to be fixed for me now with the Nov 25, 2015 release of the Toolkit.
