First off, here's the Knowledge Base Article and the Download page.
A couple of big issues have been resolved with this update. The first of which is the Email Router Rule Deployment Wizard now supports Exchange 2010. Also, the Quick Find should be faster, as it no longer occasionally runs the search twice.
For those of you having trouble with Report Wizard Reports, the issue where the error "Query execution failed for data set DSMain." has been resolved!
A lot of good updates in this Rollup, I highly recommendinstalling it soon.
