-wxWidgets no longer supports GTK 1.0.x (as did some early
-snapshots) and support for GTK 1.2.x will be phased out
-over time. Nearly all work is now done on GTK 2.0.x and
-quite a few of the enhancements of GTK+ 2.4.x and even
-GTK 2.8.x are used.
+It is required to use at least GTK+ 2.6 and some features are
+only available when using GTK+ 2.8 or higher. Note that if you
+compile wxWidgets against GTK+ 2.8 your app will still work
+with older GTK+ version down to version 2.6 as wxWidgets
+tests for the presence of newer features at run-time and it
+will fall back to a generic implementation if these features
+are not present in the GTK+ version used.
+
+wxWidgets 2.9.4 adds support for GTK+ 3, which can be enabled
+with configure option --with-gtk=3. Note that this port is
+still in development and may have significant bugs or missing
+features, and should be considered experimental.
+
+wxWidgets 2.8 still supports GTK+ 1.2, but no developement
+is done on that port anymore and support for GTK+ 1.2 will
+probably be dropped entirely. Indeed, one of the major steps
+in the developement cycle leading up to wxWidgets 2.8 was
+that the codebase for GTK+ 1.2 and GTK+ 2.0 were separated
+so that improvements and clean-ups to the GTK+ 2.0 port
+could be done without caring for GTK+ 1.2.
