Zotya,
You can find the list of changes here:http://www.datadynamics.com/forums/59193/ShowPost.aspx
The GroupFooterType functionality in DynamiCube 3 has been changed and improved from DynamiCube 2.5.When a GroupFooterType("x") = DCFCalculated you can supply your own formula using GroupFooterExpression("x"). If you do not specify a GroupFooterType for an intersection, DynamiCube will use the default setting depending on the AggregateFunc of the associated DataField.
