@martenson merged the patch to show the versions  https://bitbucket.org/galaxy/galaxy-central/commits/8d8bce91a289e040d47f9b757aae4051a0501743.

I think that is a better solution than baking the word `galaxy` into the version number (I try to argue these things aren't or shouldn't be coupled to Galaxy at all) and setting the version backwards in this case. At some point I intend to implement mechanisms for hosting multiple versions of tools that depend on the tool version instead of the tool shed linage - so I think setting the version backward is mistake.
