add call to retrieve api version
|Reported by:||Steffen Pingel||Owned by:||Alec Thomas|
It would be nice to have a call that returns the "API version" of the XmlRpc plug-in. The version could possibly have to parts where the first part would be increased on breaking api changes (e.g. an additional parameter in some method) whereas the second part would denote a non-breaking change (e.g. an additional method).
