I've set the 'Fix Version' to 5.5.28-galera just because there is no next one on the list. In fact, it's not urgent, I think we need a decision on this by GA.
Currently MariaDB-Galera builds have something like that in the %version% variables (example from a Centos 5 x86_64 RPM):
So, the version field does not say anything about Galera at all. One can still figure out it's a Galera package based on 'wsrep' in version_comment (although wsrep_23.7.rXXXX is not very nice and helpful, either).
1) do we want to mention Galera in @@version;
2) should we make the wsrep* part either more informative (the real revision) or shorter (remove rXXXX)
We briefly discussed (1) with Serg on IRC and came to conclusion that it's not critical, although possibly could make sense. So, we just need a decision.
