Version

"Version" returns the version of the data structure used in the evolution object. It will always be the same for the same version of SetReplace:

In[] := WolframModel[1 -> 2, {1}]["Version"]
Out[] = 2

Objects are automatically converted to the latest version when they are encountered by the newer version of SetReplace.
