Because I do not see how a version can be removed.

Configuration is version-less so if you can remove it there, or just change it... e.g.

~~~~~

Name: ConfigurationOfRoassal2-AlejandroInfante.37

Author: AlejandroInfante

Time: 2 June 2015, 6:48:30.901514 pm

UUID: 6257332e-2902-4cd0-ba0f-0d9180ac6e65

Ancestors: ConfigurationOfRoassal2-AlejandroInfante.36

Fixed version 1.51 and 1.52 to be 1.5.1 and 1.5.2.

Not sure if it is good approach, but even in git you can remove tags/versions and rewrite history, but if you know about it it's rarely a problem.
