Ah that’s an interesting case.  The ‘gnome’ updater checks for odd minor
release numbers already.  But in this case, it’s the ‘generic-html’
updater that kicks in, which is nice, except it doesn’t know about the
odd/even scheme.

So yes, we could have a property like you suggest that the
‘generic-html’ and ‘generic-git’ updaters (at least) would honor.
