Comment (by ryandesign@…):

 Yes we could hardcode the 0.91 branch in the livecheck, but the point of
 livecheck is to inform the maintainer when a newer version is available;
 hardcoding 0.91 would prevent us from learning when a later version such
 as 0.92 is stable. In my message I will ask the developers about this as
 well.
