ANNOUNCE: gtkmm 2.91.2

parallel with the gtkmm-2.4 ABI, of which gtkmm 2.20 is currently the latest stable 
version. This allows application developers to start using it when they choose to, 
without being forced, and without breaking existing installed applications.

gtkmm-3.0 will be mostly API-compatible with gtkmm-2.4, though some small 
changes will be needed in application source code.

API additions.

gtkmm stays in-sync with GTK+ by following the official GNOME release schedule:

Bindings for the rest of the GNOME Platform are also available, and are also
