The names of the node binaries changed from 3 to 4, so you will need to load the versions of basic and simple from v4.x to run the graph, or you will need to re-link the binaries to the old name.
There have been some minor changes to behavior, but generally, these things can be worked out fairly straightforwardly, and do not require a complete re-work of a graph.
