Ah, yes. I was meaning to link to the migration API, and I moved it at the end.

You still need to maintain a tutorial, unless it does cover
*everything* already — which is not the case.

The GTK 2.x tutorial, for instance, was a port of the 1.x tutorial,
which meant that it was both still using outdated concepts, and it was
never updated to reflect the changes that happened during the 2.x
development process. It does not talk about Cairo, for instance; or it
does not reflect changes in the GTK dependencies like GLib, GObject,
GIO, or Pango. It does not cover the accessibility API at all.

Just because the GTK+ 2.x API is frozen it does not mean that
everything around GTK+ is.

If you're writing new code and you're using GTK+ 2.x, you're sadly
Doing It Wrong™, as the kids say today.

The migration guide will, at the very least, help you *not* use
deprecated API in any case.

If you're using GTK+ 3.x, the API reference has a whole section on how
to write idiomatic GTK+ applications, and the GNOME developers website
— https://developer.gnome.org — has various guides on other components
of the stack; there are even guides on the wiki —
https://wiki.gnome.org/HowDoI — that explain how to use newer
concepts, like settings, actions, application menus, and gestures.

Ciao,
 Emmanuele.
