==============================================

* Various deprecated APIs have been removed:
 - the GtkWidget::draw-border style property
 - the GtkEntry::state-hint style property
 - the GtkTreeView::row-ending-details style property
 - the GtkRange::trough-side-details style property
 - the GtkRange::stepper-position-details style property

 - the GDK_WINDOW_DIALOG window type
 - the GTK_SELECTION_EXTENDED selection mode
 - the GtkProgressBarOrientation, GtkAnchorType and GtkVisibility
   enumerations
 - GtkDialog separators, including the GtkDialog::has-separator
   property, including setter/getter, the GTK_DIALOG_NO_SEPARATOR
   flag and the GtkMessageDialog::use-separator style property
 - gtk_status_icon_set/get_blinking
 - gdk_window_et_deskrelative_origin
 - The GtkItem class has been removed. Its functionality has
   been merged into is sole subclass, GtkMenuItem

* The GtkIconView::orientation property has been renamed
  to ‘item-orientation‘

* GtkProgressBar and GtkCellRendererProgress implement GtkOrientable
  now, and their ‘orientation‘ property have been split into
  a ‘orientation‘ property of type GtkOrientation and a boolean
  ‘inverted‘ property

* GDK no longer exports variables: gdk_threads_lock, gdk_threads_unlock,
  gdk_threads_mutex and gdk_display are no longer available

* GTK no longer exports variables: gtk_major_version, gtk_minor_version,
  gtk_micro_version, gtk_binary_age, gtk_interface_age have been
  converted to functions. gtk_debug_flags has a getter and a setter.
  Misc. variables that had been exported by the semi-private text
  API have been removed.

* All GDK keysym names have been changed from GDK_keysym to GDK_KEY_keysym;
  the previous names are still available in gdkkeysyms-compat.h.

* GtkWrapBox is a new container, which distributes its children
  over multiple rows/columns

* GTK+ now uses standard icon names when looking up stock icons

* More widgets and cell renderers have been converted to support
  width-for-height: GtkCellRendererText, GtkAccelLabel, GtkCellView,
  GtkComboBox, GtkMenu, GtkMenuItem

* Button boxes are now semi-homogeneous.

* The directfb backend has been removed
