+* gtk_tooltip_set_custom now accept a NULL custom_widget to unset the
+ old custom_widget. Custom_widget does not get destroyed when the
+ tooltip goes away.
+
+* JPEG2000 support is no longer enabled by default. It must be
+ explicitly turned on, by passing --with-libjasper to configure.
+
+* GDK has been reworked to implement 'client-side windows'. This offers
+ exciting new possibilities, such as transformed, offscreen rendering,
