The C-based GTK+ cross platform toolkit has now reached version 2.0. This version is the
basis of Gnome 2.0 as well and its libraries are not compatible in
either source or binary form with previous GTK+ applications.
FAQ and
release notes. The C++ bindings for GTK+ 2.0, called Gtkmm, is
expected to be released very soon too.
