While not available for download yet, Canon Digital Photo Pro Version 3.9.0 is shipping in the box with the new Canon cameras.
Notable new features include two additional check mark levels (4 & 5), a ratings system (Unrated, * through ***** and Reject) with simple hotkey access and Unsharp Mask added to the RAW Tools Tab.
