API

• Add a needsItemBuilder method to Renderer in Preview API. This helps to avoid building unnecessary items while refreshing preview.
• Preview API changes: Added a getDisplayName to Renderer and support for extending default preview renderers. Added a renderer manager to preview controlled with new methods in PreviewModel and PreviewController.
• Add a local scale flag in Ranking API. The value can be set from theRankingController.
• Add RangeFilter interface in Filters API to help create range filters. The filter system now automatically manages the range values and bounds. The Range object now also supports exclusive intervals.
• Add a new AttributableFilter filter type. This is useful for filters manipulating Attributable objects regardless whether they belong to a node or edge. Also note new useful abstract plugin implementations have been added to the FiltersPlugin module. Use AbstractFilter for any filter and AbstractAttributeFilter for filters based on attributes. Filter builders are also provided.
• Update to Netbeans Platform 7.1 and it's new perspective system. The PerspectiveMember SPI has to go away and will break compatibility. Top components now directly declare the perspective they belong to in the @TopComponent.Registration annotation, for instance roles = {"overview"} for the Overview perspective.
• Add a REPLACE_COLUMN event type in AttributeEvent.
• New Timeline API exposed as a stable API. Th API controls the Timeline UI component and the animation framework.
• Add a new TIME_FORMAT event in DynamicModelEvent. The event is triggered when the time format is initialized.
• Add a getGraphTable() in the AttributeModel. The GraphView elements can also have attributes using the same system as nodes and egdes. The data can be accessed through the Graph.getAttributes() method.

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.

Gephi 0.8alpha (Apr 08 2011)

New features

• Spanish and French localization (Menu Tools > Languages)
• GEXF 1.2 support (partial)
• Integrate Email Spigot - create network from emails
• Add Neighbour Filter
• Improve support of meta-edges in Statistics and Filters
• Improve usability of Filters
• Edge weight option in PageRank, which can now be used by the algorithm

• Graph files now supports GZ compression
• Better Filters support in .gephi files
• VNA Import (Thanks to Vojtech Bardiovsky)

Performance

• Label Adjust algorithm 3 times faster
• Saving/Loading projects is faster and use less memory

Removed features

• Degree Power Law metric. Reason: this is not a metric but a fit on a model. The produced chart is not sufficient to link building service determine if data fits the model correctly.
• Watts-Strogatz generator, a brand new 'Scientific Generators' plugin is about to be released, including Watts-Strogatz and many others
• 'Open project' menu has been merged in simply 'Open'

Bugfixes

(not copied)

API

• Add setCurrentQuery() method on FilterController
• Important change how modules save/load data into project files. The WorkspacePersistenceProvider interface from - ProjectAPI now uses StAX instead of DOM. The writeXML() method now uses XMLStreamWriter and readXML() XMLStreamReader. Backward compatibility can't be assured, modules have to use switch to StAX.
• Added support of shortcut keys, availability of items and sub-items creation to Data Laboratory context menu actions (NodesManipulator and EdgesManipulator). Also now Visualization API has an SPI for adding context menu actions (GraphContextMenuItem) to nodes like DataLaboratory does with NodesManipulator. Note that they share the interface ContextMenuItemManipulator from Data Laboratory API, so they are compatible, being able to reuse actions on nodes for Overview and Data Laboratory.
• Add removeMetaEdge(Edge) to manually remove meta edges. Add getTotalEdgeCount() method to globally count the number of edges, regardless if the edge is proper or meta.
• Add methods in Graph API to better combine edges and meta edges features. Add getEdgesAndMetaEdges(Node) and getTotalDegree(Node) methods, as well as their in and out variants for HierarchicalDirectedGraph.
