Previously there was a Connectivity* structure for both the control environment and the execution environment. This was necessary before because the connectivity is explicit to the from and to topology elements, so you would get this structure from the appropriate call to CellSet*. However, the symantics are changed so that the type of connectivity is selected in the worklet's dispatcher. Thus, it is now much cleaner to manage the CellSet structure in the CellSet class itself and just have a single set of Connectivity* classes in the execution environment.
