2.6.1 is the previous release version. 15.11 is just year.month of the next release version, apparently they are moving to a new numbering scheme.

Not sure about 4.0, but I think it was the working number for the next release (to avoid confusion with Python 3, I guess they call that pypy3 and have a version number also).
