API
----

* Complete rewrite of the Preview API with a new SPI which allows to extend the Preview with new renderers, item builders or render targets. The API also now offers better customization through a central property system and is optimized for external applications as well. The API is also now considered as stable.
* New DynamicStatistics SPI in the StatisticsAPI module. The interface extends Statistics and implement the calculation of metrics over time.
* Important changes in graph events breaking API compatibility. The ADD_NODES and ADD_EDGES are merged into a ADD_NODES_AND_EDGES event. Similarly REMOVE_NODES and REMOVE_EDGES are merged into a REMOVE_NODES_AND_EDGES event. GraphEventData remains the same and still contains both added/removed nodes and edges. Users may simply test if arrays returned by addedNodes(), addedEdges(), removedNodes() and removedEdges() are null before using them.
* Add new executeLayout(numIterations) method in LayoutController.
* The StatisticsController now supports synchronous algorithm execution through the execute(Statistics) method.
* Add new startAutoTransform() and stopAutoTransform() in Ranking API to control auto transformations. The model also allows to retrieve the ranking used in the auto transformation. An additional refreshRanking() method has been added in the RankingBuilder SPI for a smoother auto transformation support.
* Added a new AttributeRowsMergeStrategy interface to Data Laboratory API. This is a type of manipulator that defines and strategy for merging values of a row (node or edge) for an specific column. It should be used by other manipulators such as NodesManipulator MergeNodes
* Complete refactoring of the Ranking API to improve modularity and reach a stable version of the API. The API now also has a SPI for ranking builders and transformers. Instead of getNodeRanking() and getEdgeRanking in the model, we introduce the concept of element type and generalize methods to it. Use Ranking.NODE_ELEMENT to obtain a node ranking and Ranking.EDGE_ELEMENT for an edge ranking. Same idea for transformers, which are now defined by a unique name. Default transformers' name can be found in the Transformer interface. A RankingEvent has also been created. API users have to update to their client code to be compatible.
* Add a new interface nodes and edges share: Attributable. That allows to manipulate objects with attributes regardless if the object is a node or an edge. Node, Edge, NodeData and EdgeData now implements this interface, and a getAttributes() method has been added to Node and Edge to make development easier.
