Stable glibmm and gtkmm releases soon

[Murray Cumming <murrayc murrayc com>]

I will do the .0 releases of the current glibmm and gtkmm series in the
next few days, to try to be in sync with GNOME, who have their .0
release on March 27th:
https://live.gnome.org/ThreePointSeven

So, if you have added new API, please take an extra moment to make sure
that you don't need to fix it quickly, because you probably can't break
it later.
