You are either on 0.25.1 or 0.25-fixes. 0.25.1 is just a snapshot of
0.25-fixes at a particular time.

If you use the mythbuntu repos you will get 0.25 fixes and it is
compiled and released to the repo every day, provided there have been
some commits. Therefore if you keep up to date with mythbuntu repos
you will have the latest o.25-fixes.
