+• It it not necessary any more to provide implementations for the
+  ClutterActor::map() and ClutterActor::unmap() virtual functions, even
+  for composite actors not implementing the ClutterContainer interface.
+
+• ClutterTimeline now guarantees that the ::new-frame signal will be
+  emitted at the beginning of the timeline, as well as guaranteeing that
+  the ::completed signal will be emitted at the end of the timeline.
+
+• ClutterActor will check for the enabled property of ClutterActorMeta
+  instances (actions, constraints and effects), and will not invoke
+  ClutterActorMeta functions on disabled instances. This removes the
+  requirement for checking the property inside the ClutterActorMeta
+  sub-classes.
+
+• ClutterActorBox, ClutterGeometry and ClutterVertex install a progress
+  function for ClutterInterval, allowing the interpolation of properties
+  using them as storage types.
+
+• ClutterColor's clutter_color_from_string() function accepts CSS3 color
+  specifications.
+
+• The previously unused "axes" field in the ClutterButtonEvent,
+  ClutterScrollEvent and ClutterMotionEvent structures is now used on
+  the X11-based backends with XInput support.
+
+• ClutterListModel will honour the filter function when calling
+  clutter_model_get_iter_at_row().
+
+• ClutterClickAction does not use a pointer grab any longer, and uses
+  a capture on the stage instead.
+
+• On all platforms which allow it, ClutterStage will ask the windowing
+  system for an explicit key focus when showing the stage window. This
+  can be disabled using clutter_stage_set_accept_focus().
