+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.
+
+* GDK will now set all matching virtual modifiers in the state field of
+ key events. Depending on your X modifier map, this can lead to more bits
+ in the state field being set than before. If you are manually matching
+ key events against key/modifier combinations you should make sure that
+ you properly mask away irrelevant parts of the state field. The
+ gdk_keymap_map_virtual_modifiers() function can help with matching
+ against virtual modifiers.
+
+Release notes for 2.18
+======================
+
+* 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,
+ but it breaks some long-standing assumptions that applications may
+ have about GDK windows. Setting the environment variable
+ 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.
-* GtkAdjustment now enforces 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.
+* 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
Otherwise, enter a new bug report that describes the patch, and attach
the patch to that bug report.
-Bug reports containing patches should include the PATCH keyword in their
-keyword fields. If the patch adds to or changes the GTK+ programming
-interface, the API keyword should also be included.
