at commit 41bdf05361007f8c5186f3df9944d86bb273ed13 (for/vtk).

ENH: Change pipeline usage pattern (under Examples and */Testing only) from old style a.SetInput(b.GetOutput()) to a.SetInputConnection(b.GetOutputPort())... Changes were made by automatic replacement via regular expression matching in tcl, py, cxx and java files. Files under Examples (especially tcl and py scripts) need more review since they don't automatically run on any dashboards. Additionally, some SetInput calls may still remain. Reason for making these changes: consistency, to be good examples to people trying to learn the new pipeline.
