Microsoft Project Events Question

can anyone tell me the difference between the new argument “ByVal Info As EventInfo” and the old “Cancel As Boolean” in the new events in microsoft Project 2002/3. For example what extra functionality is gained by using ProjectBeforeTaskChange2(ByVal tsk As Task, ByVal Field As PjField, ByVal NewVal As Variant, ByVal Info As EventInfo)

instead of

ProjectBeforeTaskChange(ByVal tsk As Task, ByVal Field As PjField, ByVal NewVal As Variant, Cancel As Boolean)
