List of changes since Clutter 1.10

For detailed announcements see:

Add ClutterScrollActor
ClutterScrollActor is an actor that provides a scrollable viewport to show a portion of its children.
Add ClutterTransitionGroup and ClutterKeyframeTransition
Two ClutterTransition subclasses that provide grouping and keyframe-based transitions to the explicit animation API of ClutterActor.
Add new transformation API to ClutterActor
ClutterActor now provides a ‘pivot point’ that is used for all transformations: scaling, rotation, translation; also, any actor can be transformed by providing a 3D matrix, bypassing the decomposed transformations; finally, any actor can apply an initial transformation to its children. All matrix-based properties are also animatable.
Add multi-touch gesture recognizers
ClutterPanAction, ClutterZoomAction, and ClutterRotateAction are gesture recognizers that can be used to detect common multi-touch gestures. The ClutterGestureAction class has been modified to make it easy to create new gesture recognizers.
Layout manager improvements
ClutterGridLayout is a new layout managed implementing a flexible grid; setting the allocation of an actor will respect the actor’s easing state, making animatable layout managers easy to write; any actor can automatically expand in both the horizontal and vertical directions, and the expansion will bubble up to its parent.
ClutterCairoTexture (replaced by ClutterCanvas); ClutterTexture (replaced by ClutterImage); ClutterMedia (replaced by clutter-gst API); ClutterAnimation, ClutterAnimator, ClutterState (replaced by the implicit and explicit actor animation API); ClutterLayoutManager’s animation API (replaced by the implicitly animatable ClutterActor:allocation property); ClutterActor’s paint and pick signals have been deprecated.
List of changes since Clutter 1.11.16
Fix the device tracking for core X11 pointers
If a master input device can emit both touch and pointer events we end up in an inconsistent state; we should account for this case when tracking the stage that contains the events of each input device.
Respect text direction in BinLayout
The text direction of the children of an actor using the BinLayout layout manager should be taken into account, both when using the Actor’s align flags and when using the legacy BinAlignment flags.
Translations updates
Hindi, Telugu, Catalan, Malayalam, Japanese, Bulgarian, Kannada.
