+Release notes for 2.20
+======================
+
+* GtkStatusbar now has a message area (see gtk_status_bar_get_message_area)
+ which makes it easy to place additional widgets inside the statusbar
+ frame or to replace the label widgets. Previously, this was only possible
+ by accessing the innards of the statusbar widget directly. Applications
+ which are doing so may need some adjustments, since the addition of the
+ message area changed the internal widget hierarchy.
+
+* GtkBuilder no longer sets the "name" property of widgets to the ID
+ attribute of the <object>. Use gtk_buildable_get_name() instead of
+ gtk_widget_get_name() to obtain the ID.
+
+* GTK+ now includes introspection data, as a consequence, it gained a
+ dependency on gobject-introspection. It is possible to build without
+ introspection by passing --disable-introspection to configure.

Release notes for 2.18
======================
GDK_NATIVE_WINDOWS makes GDK create a native X11 window for each
GDK window, which might make problematic applications work better.
+* GTK+ calls signal (SIGPIPE, SIG_IGN) during initialization, to ignore
+ SIGPIPE signals, since these are almost never wanted in graphical
+ applications. If you do need to handle SIGPIPE for some reason, reset
+ the handler after gtk_init(), but notice that other libraries (e.g.
+ libdbus or gvfs) might do similar things.
Release notes for 2.16
======================
to GTK_SENSITIVITY_ON, so that the button is always sensitive or
GTK_SENSITIVITY_OFF to make it insensitive respectively.
-* In the early 2.14.x releases, GtkAdjustment was changed to enforce
- that values are restricted to the range [lower, upper - page_size].
- This has always been the documented behaviour, and the recommended
- practice is to set page_size to 0 when using adjustments for simple
- scalar values, like in a slider or spin button.
- Due to the large number of applications that are affected by this
- change, the behaviour has been reverted to the old behaviour in
- 2.14.3, with an explicit warning that this change will be
- reintroduced in 2.90.

* gdk-pixbuf will use GIO for mime type detection if possible. For
this to work, shared-mime-info needs to be installed and XDG_DATA_DIRS
