Maybe another thing to explain to higher-level library developers, even if it looks obvious: using the same minor versions: 89 (unstable), 90 (semi-stable), 91, etc. So that there is some kind of consistency between libraries, even if the major version is not the same. -- Sébastien _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-devel-list
