+Overview of Changes from GTK+ 2.17.2 to 2.17.3
+==============================================
+
+* GtkFileChooser:
+ - Shows the size column by default now
+
+* GtkStatusIcon:
+ - Has a title property, which can be used by ATs when they
+   read status icons
+
+* GtkInfoBar:
+ - The default theme now includes color definitions for infobars
+ - The ::use-tooltip-style style property has been removed
+
+* The client-side windows branch has been merged; GDK now maintains
+  its own window hierarchy client-side, and only uses X windows where
+  unavoidable. Some of the benefits of this change are
+  - Reduced flicker
+  - The ability to do transformed and animated rendering of widgets
+  - Easier embedding of GTK+ widgets e.g. into Clutter scene graphs
+  This is a fundamental change to the way GDK works, so watch out for
+  regressions.
