Sergey, just to follow up on this:

The download page mentions that "In addition to fixes to the core product, this patch contains significant enhancements to the Reporting features". Where those changes are documented? Shouldn't such document be a part of SP2?

The changes in the ReportBuilder are going to be pretty self-evident. Additional docs would be a nice-to-have for the beta, I agree, but you are going to find most things quickly.

The underlying ReportListener enhancements (both to support the features exposed in the Builder, and other stuff not exposed) is a little harder to get to, but remember that the class libraries are in the FFC directory, and the PEMs have comprehensive comments so you can get additional info with a little digging.
