And to spell that out even more, it's not a problem that gtkmm 2.4 has small
API breaks compared to gtkmm 2.2, because different versions of the API are
parallel installable (just like gtkmm 1.2 and gtkmm 2.2 are parallel
installable). You use the new API when you want, and it doesn't affect your
application until then.
