Michael Catanzaro 718af17905 info-overview: show only the GNOME major version 
What we have is the GNOME Shell version, which is NOT the same as the
GNOME version. I thought it'd be nicest to rename this to "GNOME Shell
Version" but it seems we want to keep that as an internal codename not
exposed to users. So instead, let's just show only the major version,
which should hopefully match. This is very generic and much less useful
but I don't see a better solution.

See previous discussion in:
