All the additional tools you've come to depend on have been updated for ConfigMgr 2012 R2, plus some new additions join the pack.
The Microsoft System Center 2012 R2 Configuration Manager Toolkit is a group of 15 tools that extend ConfigMgr 2012 in some way, providing features for troubleshooting, monitoring, security, and management.
Here's what's included with this updated release:
As you can see from the table, there are three new tools: DP Job Manager, Collection Evaluation Viewer, and the Content Library Explorer.
DP Job Manager aids in troubleshooting and managing the jobs created to distribute content across the distribution points in the hierarchy.
Collection Evaluation Viewer gives details on collection evaluation to help admins troubleshoot issues.
Content Library Explorer gives deep insight into the content library to provide the ability to determine and solve problems.
