• Fixed a performance issue in SchemaElementType.toString() by pre computing the hierarchy on initialisation. SchemaElementType.getHierachy() is a slow method and was being called too many times. The performance improvement has made it about 1.7 times faster to load, save and work with graphs.

• Fixed the views that have not been upgraded to the new View Framework to have the font size applied to the Top Component on load.

• Updated SchemaElementType.isSubTypeOf to take overridden types into account.

Changes in September 2018

• Renamed ColorValue to ConstellationColor to make it clearer what it should be used for and to avoid conflicts with external classes.

• Renamed TemporalFormatting.DATE_TIME_FORMATTER to TemporalFormatting.UTC_DATE_TIME_FORMATTER and TemporalFormatting.DATE_TIME_WITH_MILLISECONDS_FORMATTER to TemporalFormatting.UTC_DATE_TIME_WITH_MILLISECONDS_FORMATTER in the Core Utilities module. These DateTimeFormatter constants are now build using the DateTimeFormatterBuilder ensuring they convert dates to UTC correctly.

• Updated the support package generation to ignore the heapdump file as it is likely to be several gigabytes in size.

Changes in May 2018

• Added FilterPlugin to the Core Data Access View module.

• Added PasswordParameterType into the Core Plugin Framework module. This change has also removed the capability of StringParameterType to support passwords.

• Added strict DateTimeFormatter's based on DateTimeFormatter.ISO_INSTANT to the TemporalFormatting class in Core Utilities.

• Fixed a performance issue by reducing the amount of “Find State” saves made to the graph as it’s causing graph write lock contention for a trivial GUI state that will be already covered when you run a search, switch graphs or save the graph.

• Fixed an issue handling invalid Glyphs.

• Fixed some performance issues with the Map View.

• Removed deprecated methods being PluginGraph.executePluginLater, PluginGraph.executePluginNow and PluginGraph.updateGraph.

• Renamed Plugin.id to Plugin.ID

• Updated JOGL to 2.3.2 and Processing to 3.3.6 to resolve OpenGL issues with the Map view.

• Updated default node and transaction colors in order to ensure overlay colors stand out more.

• Updated default node z2 value.

• Updated password obfuscation to use a service lookup to get the key. To use it implement PasswordKey in the Core Security module.

Changes in April 2018

• Added New Nebula into th Experimental->Tools menu

• Added an FPS counter OpenGL renderer that can be enabled from the Debug preference tab.

• Added new MatrixUtilities class for constructing useful matrices from a graph.

• Added simple icon shaders for rendering basic icons on the graph.

• Removed the REST API endpoints /forward (forwarding a request to another HTTP server), /resources (offering embedded web resources), and /static (serving resources from a specified local directory) have been removed.

• Renamed ApplicationPreferenceKeys.DEFAULT_FREEZE_GRAPH_VIEW to ApplicationPreferenceKeys.FREEZE_GRAPH_VIEW_DEFAULT in the Core Preferences module.

• Renamed SharedDrawable.getIconShader to SharedDrawable.getVertexIconShader to differentiate it from SharedDrawable.getSimpleIconShader.

• Updated Core Web Server code so the workings out of the web servlets into separate \*Impl.java classes. This makes the workings transport independent, in preparation for adding a non-HTTP transport. In theory, there should be no change in functionality.

• Updated the Core Web Server module to add a filesystem REST transport.

• Updated the constructor for Decorators to expect its parameters in a clockwise order: north-west, north-east, south-east, south-west.

• Updated the various \*Preference panels to follow and more of an MVC pattern.

Changes in March 2018

• Added FactColorTranslator and FactToSizeTranslator to the Core Analytics View module.

• Added FirstAnalyticPlugin to the Core Analytics View module.

• Added FirstFactAggregator in the Core Analytics View module.

• Added a new attribute called isLabel to SchemaAttribute in the Core Graph Module with the intention of allowing the schema to decide if the attribute should appear as a GraphLabel on a vertex or transaction.

• Added a new isLabel and isDecorator attributes to SchemaAttribute with the intention of allowing the schema to decide if the attribute should appear as a GraphLabel or Decorator on a vertex or transaction.

• Added equivalent method to SchemaAttribute allowing you to compare with an Attribute object.

• Renamed ClusterAggregator to FirstClusterAggregator in the Core Analytics View module.

• Renamed MultiScoreResult.getUniqueNames to MultiScoreResult.getUniqueScoreNames in the Core Analytics View module.

• Renamed COLOR_BLAZE in the CorePluginRegistry to ADD_CUSTOM_BLAZE.

• Updated entries within the Tools and Experimental menu.

• Updated ListeningTopComponent to allow for the update and removal of change handlers.

  • addAttributeChangeHandler was renamed to addAttributeValueChangeHandler.

  • addGlobalChangeHandler, addStructureChangeHandler, addAttributeCountChangeHandler and addAttributeValueChangeHandler now return the Monitor objects associated with that handler.

  • updateGlobalChangeHandler, updateStructureChangeHandler, updateAttributeCountChangeHandler and updateAttributeValueChangeHandler have been added to allow modification to the behaviour of a handler.

  • removeGlobalChangeHandler, removeStructureChangeHandler, removeAttributeCountChangeHandler and removeAttributeValueChangeHandler have been added to allow removal of a handler.

  • removeIgnoredEvent has been added to allow removal of an ignored event.

Changes in December 2017

• Added forward slash (/) to the list of special characters to escape in LuceneUtilities in the Core Utilities module.

• Removed extra FindStatePlugin calls from the ColorCriteriaPanel which will help reduce unnecessary write locks on the graph and reduce overall threads being forked.

• Moved au.gov.asd.tac.constellation.schema.analyticschema.concept.SnaConcept to au.gov.asd.tac.constellation.algorithms.sna.SnaConcept in the Core Alogorithms module.

• Moved some centrality plugins to au.gov.asd.tac.constellation.algorithms.sna.centrality in th Core Alogorithms module.

• Moved the social network analysis plugins into a new parent package au.gov.asd.tac.constellation.algorithms.sna in the Core Alogorithms module.

• Updated the ControlsFx library to version 8.40.13 so that it is compatible Java 8u144.

• Updated to NetBeans 8.2 and Java 8u144.

Changes in August 2017

• Added new module Core Web Server to hold all the classes related to managing local web servers and the Constellation REST API.

• Added ConstellationApiServlet to abstract away the idea of checking a secret for each api call.

• Added TypeServlet to allow operations related to types in the Constellation REST API.

• Added SchemaVertexTypeUtilities.getTypeOrBuildNew() and SchemaTransactionTypeUtilities.getTypeOrBuildNew() to the Core Graph module.

• Added an ImageConcept to the Core Analytic Schema module.

• Fixed a bug with types serialisation. Types are now loaded exactly the way they were saved to the graph file by properly serialising types in VertexTypeIOProvider and TransactionTypeIOProvider.

• Renamed all *Popup classes that implement ContextMenuProvider to end in *ContextMenu.

• Removed AnalyticVertexType from the Core Analytic Schema module.

• Removed ApplicationPreferenceKeys.SCRIPTING_LANGUAGE and ApplicationPreferenceKeys.SCRIPTING_LANGUAGE_DEFAULT from the Core Preferences module as we have made a design choice to use Python as our scripting language.

• Removed the topLevelType attribute from SchemaElementType as it can be calculated.

• Updated AnalyticConcept to build types using SchemaVertexType and SchemaTransactionType.

• Updated SchemaElementType by removing the setIncomplete() method which means that Types are now immutable.

• Updated SchemaVertexType and SchemaTransactionType to be final. Any type object has to be either one of these which simplifies types.

• Updated the Content ContentConcept in the Core Analytic Schema module with more attributes.

• Updated the properties map in SchemaElementType to be a Map of String to String so that serialisation is simplified.

Changes in July 2017

• Renamed package au.gov.asd.constellation.utilities.geo to au.gov.asd.constellation.utilities.geospatial.

• Renamed the ChangeSelection plugin in the Data Access View module to SelectAll.

• Updated the Map View to allow for custom overlays by extending the MapOverlay class. The current info and tool overlays have been converted to this framework.

• Updated the SchemaAttributeUtilities class so that any schema attribute lookup requires a GraphElementType to be specified. This is to avoid dealing with conflicts where a vertex and transaction attribute with the same name exist.

Changes in June 2017

• Fixed a bug detecting graphics card compatibility.

• Moved all *AttributeUpdateProvider classes in ‘au.gov.asd.tac.constellation.graph.io.versioning’ to ‘au.gov.asd.tac.constellation.graph.io.providers.compatability’.

• Removed the @Deprecated tag for classes in *compatibility packages. These classes will need to remain to support backward compatibility and can not be deprecated. To avoid them being used a comment has been added at the top of each class.

• Renamed package ‘au.gov.asd.tac.constellation.schema.simpleschema.update’ to ‘au.gov.asd.tac.constellation.schema.simpleschema.compatibility’.

Changes in May 2017

• Added RawData.isEmpty().

• Added ScoringAnalyticPlugin and MultiScoringAnalyticPlugin to simplify the addition of analytics to the Analytic View for the case where the analytic simply needs to run a plugin and read the resulting scores.

• Added SelectTopN to the Data Access View module to select the top n nodes based on the transaction count and type.

• Added TextPluginInteraction in the Core Plugin Framework module that will be useful in unit tests.

• Added a MultiScoreResult result type to the Analytic View, as well as aggregators and translators allowing calculations and visualisation. This result type is designed to support any analytic which produces multiple scores as output.

• Added ability to override the foreground icon associated with a type by adding custom icons named the full hierarchy of that type.

• Fixed bugs with the SimpleSchemaV*UpdateProvider classes that caused the wrong icons to be set.

• Moved the DEFAULT_FONT constant from the FontUtilities class in Core Visual Support to ApplicationPreferenceKeys in Core Preferences.

• Removed DebugUtilities from the Core Preferences module as the convention is to use different java.util.logging.Logger levels.

• Removed StringBuilderOutputStream due to its implementation being fundamentally wrong. Using ByteArrayOutputStream and toString(StandardCharsets.UTF_8.name()) is a better approach.

• Removed the representation() method in SchemaElementType and replaced it with the getHierarchy method which is now called by the toString() method in SchemaElementType.

  • When setting types in RecordStore objects, you should no longer use getName() it now returns the name of the type. Given toString() has been overridden, it will return the type’s hierarchy as a string.

• Renamed 'getChoices' (and similarly named methods) to 'getOptions' and 'getChecked' to 'getChoices' in the MultiChoiceParameterType class.

• Renamed 'getChoices' (and similarly named methods) to 'getOptions' in the SingleChoiceParameterType class.

• Renamed GenericTopComponent to AbstractTopComponent in the Core Functionality module.

• Renamed package ‘au.gov.asd.tac.constellation.core.composites’ to ‘au.gov.asd.tac.constellation.core.composite’.

• Renamed the VisualConcept.VertexAttribute.UNIQUEID attribute to VisualConcept.VertexAttribute.IDENTIFIER.

• Updated XmlUtilities to optionally handle XML namespaces. Namespaces can be enabled by setting the 'namespaceAware' flag in the constructor for XmlUtilities, and then you can use any method suffixed with ‘NS’ to take advantage of namespaces.

• Updated all font references in CSS files to use em instead of px so that fonts scale based on the screen resolution.

• Updated how schema element types are stored in a .star file, where instead of the type name, the entire type hierarchy is now used. This is a backwards compatible change.

• Updated the DataAccessPane to factor in the category position along with the plugin’s position which ensures that the favourites category is sorted similarly.

• Updated the implementation of the resolveVertex and resolveTransaction methods in the AnalyticSchema class to allow for hierarchical names specified by multiple types separated by the “.” character.

• Updated the SimpleSchemaV*UpdateProvider and AnalyticSchemaV*UpdateProvider classes by rearranging the logic so that each update provider is now responsible to manage the update of the concept it uses first. That is for example, SimpleSchema*UpdateProvider handle’s the label attribute whilst the AnalyticSchema*UpdateProvider handles updates to the Type attribute.

  • The update provider no longer runs a Complete With Schema

  • The responsibility of the UpdateProviders is to only handle mandatory changes that would otherwise break the graph to said change. It will be up to the graph’s schema rules to update all elements on an old graph to be up to date with the latest look and feel. This can be done via Tools -> Complete with Schema or F5.

Changes in April 2017

• Added GeoUtilities.dmsToDd to convert a Degrees-Minute-Seconds formatted geospatial coordinate to Decimal Degrees.

• Added DownloadImageUtilities to the Core Utilities module.

• Added HttpsUtilities.readErrorStreamAndThrow in the Core Utilities module to make reporting errors from services consistent.

• Added IntegerObjectAttributeInteraction, LongAttributeInteraction and LongObjectAttributeInteraction classes so that the corresponding attribute types are properly represented in the user interface.

• Added LongObjectAttributeDescription class for completeness.

• Added a “Start Jupyter notebook” capability.

• Added the ability to add plugins to your favourites in the Data Access View.

• Fixed a bug in ConsolidatedDialog that would not deselect correctly.

• Fixed a major performance issue where table view state updates where running on the EDT causing CONSTELLATION to lock up.

• Fixed a serious bug when extending Types and calling VertexTypeAttributeDescription.getString() causing a mis-representation of the type as a string. This was evident when retrieving the type value from a RecordStore. This is a temporary fix until the Types design is reviewed and possibly overhauled.

• Fixed bugs with quick search, advanced find and recent search queries.

• Renamed AbstractCalculatorUtility to AbstractCalculatorUtilities in the Core Scripting module.

• Renamed ClipboardUtility to ClipboardUtilities in the Core Functionality module.

• Renamed ConsolidatedMultipleMatchesDialog to ConsolidatedDialog in the Core Functionality module.

• Renamed DebugUtility to DebugUtilities in the Core Preferences module.

• Renamed GraphUtil to GraphUtilities in the Core Arrangements module.

• Renamed SimpleStringUtilities in the Core Utilities module to StringUtilities and added new functionality.

• Renamed StringUtilities in the Core Utilities module to OldStringUtilities and deprecated it.

• Updated HttpsConnection in the Core Utilities module to use the UTF-8 charset by default for application/json and application/xml content types.

• Updated all references to UTF-8 to use StandardCharsets.UTF_8.

• Renamed ArrangementRegistry to ArrangementPluginRegistry for consistency with other plugin registry classes.

• Added ability to set custom context menu items on the SeletableLabel class used in the Conversation View.

• Moved resources for rendering pill buttons in JavaFX from the conversation view module to the visual support module so they can be used anywhere in the application.

• Renamed AlgorithmsRegistry to AlgorithmPluginRegistry for consistency with other plugin registry classes.

• Renamed references to plugins which extend NetworkxCentralityPlugin, NetworkxImportancePlugin and NetworkxSimilarityPlugin in the AlgorithmPluginRegistry. They are all now appended with '_NX' to differentiate them from java implementations of the same algorithms.

Changes in February 2017

• Added CreateCompositesFromDominantNodesPlugin.

• Added SetDrawFlagPlugin.

• Added SetVibilityAboveThresholdPlugin which can be used to toggle the visiblity status instead.

• Added VisibleAboveThresholdPlugin which will update the draw flags based on whether the count of nodes has exceeded the threshold.

• Added a new module called Core Graph Utilities.

• Added au.gov.asd.tac.constellation.graph.utilities.io.CopyGraphUtilities.

• Added au.gov.asd.tac.constellation.graph.utilities.io.SaveGraphUtilities. The method saveGraphToTemporaryDirectory can be used to save graphs in unit tests.

• Added au.gov.asd.tac.constellation.utilities.io.StringBuilderOutputStream as a alternative to java.io.StringWriter which uses StringBuilder instead of StringBuffer as the underlying implementation. Using StringBuilderOutputStream in say com.fasterxml.jackson.core.JsonFactory.createGenerator() can avoid an OutOfMemoryError.

• Fixed a bug where the graph visibility above threshold was no longer working.

• Fixed a major bug with GraphRecordStoreUtilities.getSelectedVerticesBatches() where the selected nodes were not correctly being added to the Recordstore.

• Moved au.gov.asd.tac.constellation.schema.analyticschema.utilities.SubgraphUtilties to au.gov.asd.tac.constellation.graph.utilities.SubgraphUtilties

• Moved the DeleteAllPlugin and DeleteSelectionPlugin to au.gov.asd.tac.constellation.core.delete.

• Moved the Dim plugins to au.gov.asd.tac.constellation.core.dim in the Core Functionality module.

• Moved the PermanentMergePlugin to au.gov.asd.tac.constellation.core.merge in the Core Functionality module.

• Removed ArrangeInComponentGridPlugin which was a duplicate of ArrangeComponentsInGridPlugin

• Removed ToggleVisibleAboveThresholdPlugin.

• Removed undo() and redo() methods from Graph. GraphCommits are tied to UndoableEdit objects, which are managed by a Swing UndoManager. The manager may call undo() or redo() on these edit objects at will, noting that they run asynchornously, because the EDT may not get a lock on the graph. No Future<?> to wait upon is available for these methods, meaning that it no longer makes sense to interact with the undo manager from the Graph in a programmatic way. Reimplementing these methods is desirable, but would require that something internal to CONSTELLATION code also keeps track of the UndoableEdit objects and has some way of knowing when a given edit has completed its undo/redo method.

• Renamed CorePluginRegistry.COPY_SELECTED_ELEMENTS to CorePluginRegistry.COPY_TO_NEW_GRAPH.

• Renamed HLGraph in the Core Graph module to SGraph.

• Renamed HLReadableGraph in the Core Graph module to SReadableGraph.

• Renamed HLWritableGraph in the Core Graph module to SWritableGraph.

• Renamed composites package in the Core Functionality module to composite.

• Renamed dialogs package in the Core Functionality module to dialog.

• Renamed selection package in Core Arrangements to select.

• Renamed the drawing package in the Core Functionality module to draw.

• Renamed the view package in the Core Functionality module to display.

• Updated the “visual_state” attribute to be an attribute called “camera”, of type “camera”, that is a GRAPH rather than META attribute. A SchemaUpdateProvider and an AttributeUpdateProvider will automatically make this change when old graphs are loaded. To access the camera attribute, use VisualConcept.Graph.CAMERA.

  • GraphVisualAccess.getX(vertex) already uses this pattern. Note that as with any default values in the VisualDefault class, these x,y,z defaults need to be respected when interacting with the CONSTELLATION's visualisation framework. Higher level plugins/views are free to do whatever makes sense in the absence of x,y,z attibutes (for example arrangements would probably just throw a plugin exception).

  • In the absence of x, y, or z vertex attributes, the default visual values of these attributes are now considered to be equal to the id of the vertex. The correct pattern to get an x, y, z value in the application for visualisation purposes is:

  final int `xAttribute` = `VisualConcept.Vertex.X.get(readableGraph);`
  final float x = `xAttribute` != `Graph.NOT_FOUND` ? `readableGraph.getFloatValue(vertexId)` : `VisualDefaults.getDefaultX(vertexId);`

• Updated GraphVisualAccess explicitly checks for null values of the Camera attribute on the graph and returns VisualDefaults.DEFAULT_CAMERA instead. Note that the Camera shouldn’t ever really be null, but as it is possible to set it programmatically (through scripting view), it is considered safer and more convenient to prevent the Visualisation framework itself from having to deal with null cameras.

Changes in January 2017

Major Changes to Rendering and Event Handling

• COSNTELLATION's visualistion and event handling framework has been reimplemented from the ground up. Performance, stability, correctness, extensability, and the design concept underlying it have all been greatly improved. The user experience should remain mostly the same.

• There is now a separation between three main components that were previously highly coupled: event handling, visualisation, and the graph. The class VisualManager handles all communication between these components.

• VisualProcessor is an abstract base class for any component that provides a visualisation of the graph.

  • GLVisualProcessor is an implementation which models the old open GL renderer.

  • A lot of high level stuff in the GL Renderer has been rewritten as well, but low level stuff like the Vector/Matrix utility classes and the shaders themselves are mostly the same.

  • A simpler lightweight renderer (using Swing for example) could be implemented with relative ease as a subclass of VisualProcessor.

• VisualAccess is an interface that VisualProcessors must now use to access the graph. They are not allowed to have reference to the graph directly.

  • GraphVisualAccess is the default implementation for CONSTELLATION graphs.

  • Theoretically VisualProcessors could visualise other ‘graph-like’ data structures if they implement VisualAccess

• InteractionEventHandler is an interface for responding to mouse and keyboard gestures (as generated by AWT) on a CONSTELLATION graph.

  • DefaultInteractionEventHandler is the default implementation in CONSTELLATION. It contains code that performs a similar function to the event handling code that used to be in GraphRenderer.

  • VisualAnnotator and VisualInteraction are two interfaces that InteractionEventHandler depends on in order to help it translate gestures into graph actions/visualisations.

  • InteractiveGLVisualProcessor extends GLVisualProcessor to satisfy the VisualAnnotator and VisualInteraction interfaces so that the DefaultInteractionEventHandler can respond to gestures on CONSTELLATION graphs rendered in OpenGL.

• Updates to a VisualProcessor from something like the event handler arrive in the form of VisualChange objects that are sent to a VisualManager (wrapped in VisualOperations).

  • The VisualChange/VisualOperation framework’s purpose is to allow components to update the visualisation of a graph efficiently and without having to commit their changes first.

  • The previous GraphRenderer achieved this, but only by being highly coupled with a Graph, and it had lots of logical flaws in its processing model. The new framework is rigorous and stable by separating data from its visualisation.

  • Whilst the event handler is the primary client of this model, other components could be written to take advantage of it.

  • Animation has been rewritten to use this model. Previously they directly maniuplated specific buffers on the GL context, which meant they were highly coupled with the renderer, and could not be used by alterate visualisations.

• A few features have been removed or now behave slightly differently:

  • Animations are now slower on large graphs. They may be able to be optimised in the future but this is considered low priority.

  • Some experimental animations have been removed.

  • You can no longer interact with an animation. This may also be fixed in the future, but it would be require a decent amount of work and is currently low priority.

  • Direction indicators no longer move when the mouse cursor moves (only when you rotate/pan the graph). They should be re-implemented as an animation, which would require a reasonably simple expansion of the animation framework to cater for utilising non-graph visual operations.

  • Lines and nodes are no longer Anti-Aliased. The old method, however, was slow, deprecated and caused artifacts when AA was turned off in the graphics card settings. Graphs now render correctly regardless of the AA settings on the card (although currently enabling AA gives no visual improvement). AAing may be implemented in the future by multisampling the graph texture.

  • On large graphs, the renderer will update slightly later than the rest of the views (when creating nodes etc.). The display always took (at least) this long to update, but other views used to wait. This may be tricky to fix, but is not considered critical.

  • Note that whilst the graph will display that it is busy and prevent interaction during a write lock, the same will not occur during read locks. When a read lock is in progress, events will be queued and the display will not be updated until the read lock is released at which point all queued events will be processed in quick succession so that the event handler ‘catches up’. This effect can be seen by running “Experimental > Five Second Read Lock” and then trying to rotate/pan the graph. While this looks bad in this instance, in practice due to the brevity of read locks (but also their potential to be obtained at any point in time during the possession of a write lock), holding up but not terminating the event handler’s main loop is the most sensible course of action.

• Fixed all known memory leaks.

• Fixed failing unit tests.

• Fixed some dialogs fading to the back.

• Fixed the Plugin Reporter from causing JavaFX to use up all the memory by removing PluginReporterPane's after they reach MAXIMUM_REPORT_PANES.

• Fixed various bugs.

• Renamed the Country utility class package name from countries to geo.

• Reviewed and finalised icon set.

• Updated the format when saving a graph file to use json objects for the color and the decorations attribute.

• Double escaping strings in the decorations no longer occur.

Changes in November 2016

• Added JMultiChoiceComboBox class to the Core Utilities module. This class provides a Swing alternative to JavaFX's MultiChoiceComboBox.

• Added MarkerCache class which manages markers on the Map View and can be looked up. This grants the Data Access View the ability to query locations from the Map View.

• Added REST API functionality for RecordStore, static files and icons.

• Added the ability to blend a color with an icon image on creation.

• Added the ability to delete a vertex or transaction from a GraphRecordStore by setting the DELETE_KEY key.

• Fixed the bug in ValueInputPanes which was causing old entry to appear after the text was modified.

  • The recent values combo was updated when a plugin was run, causing its selection model to update, which in turn caused the parameter it was managing recent values for to change right at the point of plugin execution. Temporarily disabling the listener from Recent Values -> Parameter whilst inside the RecentValues updating listener solved the problem.

• Removed FreezeGraphViewPreferencePlugin because it is only a preference change and does not need to be a plugin.

• Renamed get GraphReadMethods.getAttributeLabel() to GraphReadMethods.getAttributeName() for consistency.

• Updated GraphRecordStoreUtilities.getVertices() to return singleton vertices.

• Updated Python REST client which can now be downloaded.

• Updated the majority of built-in icons available to Constellation to have a more flat, iconic style with transparent backgrounds. This makes the core icon set consistent and allows us to make better use of background icons for analytic purposes.

Changes in October 2016

• Added LogAction to show the CONSTELLATION logs to the user.

• Added a “Support Package” menu item under help which zips the CONSTELLATION logs.

• Added a DataAccessState object which currently saves the String parameter values in the “Gobal Parameters” section of the Data Access View when you press Go. This parameters are saved with the graph so that they can be loaded when the graph opens.

• Added an option for RecordStoreServlet to return JSON suitable for Pandas.DataFrame.from_items(). The DataFrame JSON parser is much faster.

• Added missing type qualifiers in GraphRecordStoreUtilities methods.

• Added support back for attr_list attribute type which were found in legacy graphs. The attr_list attribute is converted to the currently supported Graph attributes in SimpleSchemaV1UpdateProvider.

• Modified the WritableGraph.flush() method to take a boolean parameter indicating whether or not GraphChangeListeners will be notified.

  • The use case for this is performing a series of quick updates on the graph that new ReadableGraphs need to be able to see, but that views don’t need to respond to - for example animations, event handling, etc. In this case, all views will still respond to the series of changes when commit() is called at the end of the WritableGraph's lifecycle.

• Renamed ParameterIO to ParameterIOUtilities.

• Updated ConstellationDialog to dispose when the hideDialog is called which should free up resources.

Changes in September 2016

• Added a new Map View based on the third party libraries 'Unfolding Maps’ and 'Processing'.

  • Maps are rendered using OpenGL through Processing allowing for greater performance and flexibility in what can be drawn.

  • Provides two-way interaction between the graph and the map by making use of the new generic top component framework.

  • Provides ability to add custom maps by extending the MapProvider class.

  • Provides an information overlay which displays the location of the mouse pointer, the current zoom level and a scale bar.

  • Provides ability to place map providers in debug mode by overriding MapProvider.isDebug. This will extend the information overlay to also provide debug information.

  • Provides support for point, line, polygon and multi markers. Shape-based markers can be added to the graph by inserting GeoJSON into the 'Geo.Shape' attribute. You can build GeoJSON for 'Geohash' type nodes using Geohash.getGeoJSON.

  • Currently limited to rendering maps in the Web Mercator projection only.

• Added SchemaElementType class as common base class for the SchemaVertexType and SchemaTransactionType classes.

• Added a REST API. Initially this allows a RecordStore to be added to the active graph.

• Added a ScriptingAction lookup to allow more actions to be added to the Scripting view Actions drop-down menu.

• Fixed various bugs.

• Renamed FeedbackHandler to SupportHandler and changed the menu name from “Feedback…” to “Support”

• Renamed IconManager.getIconObjects to IconManager.getIcons.

• Updated SaveResultsFileWriter.writeRecordStore to be memory efficient which fixes a java.lang.OutOfMemoryError exception and removed SaveResultsFileWriter.write.

• Updated plugins to provide their own arrangements after being run by overriding RecordStoreQueryPlugin.completionArrangement(). By default any RecordStoreQueryPlugin will now finish with an Grid arrangement (which is fast). This is a breaking change which replaces RecordStoreQueryPlugin.arrangeOnCompletion().

• Updated some Alert dialogs to use the Netbeans DialogDisplayer API to enforce modality.

• Updated the internal web server to listen on only the loopback address instead of all addresses, and has a default port instead of being dynamically assigned.

Changes in August 2016

• Added Analytic View v2 framework.

  • Any plugin can now be used as an analytic using the AnalyticPlugin class.

  • Pre-canned questions are now extensible using the AnalyticQuestion class.

  • Both internal and graph visualisations are now extensible using the InternalVisualisation and GraphVisualisation classes respectively.

  • Note that adding new analytics may require the definition of a new result type using the AnalyticResult class, as well as the construction of an AnalyticTranslator class to translate between your result and any visualisations you wish to enable.

• Added IntegerObjectAttributeDescription to handle integer type attributes which could also be null.

• Added generic JavaFxTopComponent and ListeningTopComponent classes to abstract away the creation of new views in CONSTELLATION.

• Assigned names to common threads to assist with debugging.

• Fixed various bugs.

• Fixed various performance enhancements to type lookups.

• Improved the type hierarchy used by the Analytic dominance calculator.

• Moved au.gov.asd.tac.constellation.graph.GraphChangeEvent to au.gov.asd.tac.constellation.graph.monitor.GraphChangeEvent.

• Moved au.gov.asd.tac.constellation.graph.GraphChangeListener to au.gov.asd.tac.constellation.graph.monitor.GraphChangeListener.

• Moved utilities for interacting with schemas from the SchemaFactory class to the SchemaFactoryUtilities class.

• Removed SchemaFactory.getPosition in favour of using a ServiceProvider position annotation.

• Removed the CoreExtFx module.

• Renamed SimpleSchemaFactory.SIMPLE_SCHEMA_NAME to SimpleSchemaFactory.SIMPLE_SCHEMA_ID.

• Renamed arrow icons from UP to ARROW_UP, DOWN to ARROW_DOWN etc.

• Replaced ControlsFX dialogs with JDK's Alert class.

• Updated module short and long descriptions.

• Updated platform to use Java8u92 and Netbeans 8.0.2

• Updated regular expressions used for the Phone Number, Email IPv6 Address, Country and Geohash types.

• Updated various menu item positions.

Changes in July 2016

• Added “Templates” which allow users to save multiple custom visualisations. Templates are essentially constellation files in disguise - however only the graph attributes are saved, no graph element data.

  • Menu items (including icons) have been added to allow easy creation of graphs from templates, saving templates, and management of templates.

  • Management of templates allows templates to be deleted, and also set as the default graph to open when the user selects New Graph (or hits control+N).

• Added HttpsUrlConnection class, a builder pattern to create a HttpsUrlConnection with sensible defaults like using GZIP compression and the user agent string set to ‘CONSTELLATION’.

• Added HttpsUtilities class, a utility class to safely retrieve streams from a HttpsUrlConnection.

• Added ObjectAttributeDescriptions class which allows you to quickly define an attribute description for any attribute backed by a class extending Object.

• Added a lot of Javadocs and fixed Javadoc warnings.

• Added org.apache.poi and org.apache.commons.lang as dependencies.

• Added the GraphLabels and Decorators classes for specifying labels and decorators on a graph.

• Added the ability for graph attributes to provide an attribute merger so that you can decide what happens when attributes merge.

• Fixed memory leak in Data Access View.

• Fixed minor bugs relating to attributes, including correctly saving and loading default values for icon attributes, and fixing the previously non-functioning ‘set default value’ option when creating/modifying a new attribute in the attribute editor.

• Fixed various bugs.

• Moved some preferences from the ApplicationPreferenceKeys to DebuggingPreferenceKeys.

• Removed ability to set default values for visual attributes through preferences in favour of the new template system. The changes have been explained in a what’s new entry to avoid user confusion.

• Removed bespoke editors such as “Edit > Labels” in favour of using the streamlined approach provided by the attribute editor.

• Removed the CorePluginGuide module.

• Renamed VisualConcept.TransactionAttribute.COLOR_REFERENCE to VisualConcept.GraphAttribute.TRANSACTION_COLOR_REFERENCE.

• Renamed VisualConcept.VertexAttribute.COLOR_REFERENCE to VisualConcept.GraphAttribute.NODE_COLOR_REFERENCE.

• Renamed all attribute name constants e.g. HierarchicalState.ATTR_NAME renamed to HierarchicalState.ATTRIBUTE_NAME.

• Renamed package au.gov.asd.tac.constellation.attributeeditor.handler to au.gov.asd.tac.constellation.attributeeditor.editors.

• Renamed package au.gov.asd.tac.constellation.attributeeditor.handlerimplementation to au.gov.asd.tac.constellation.attributeeditor.editors.operations.

• Renamed the PreferenceKeys class to ApplicationPreferenceKeys.

• Renamed the Rule class to QualityControlRule.

• Updated StringUtilities class to streamline the serialisation of the reworked visual attributes such as labels and decorators.

• Updated UpdateProvider class to convert from old graphs to new graphs have been included (meaning that the old graph labels and decorators framework still exists in a compatibility package).

• Updated various menu item positions.

• Updated visual attributes (and visual properties previously not exposed as attributes) so they can be used as regular graph attributes.

Changes in June 2016

• Fixed a dormant graph locking bug.

• Fixed various bugs.

• Improved Schema API.

  • The way in which graph schemas are created and controlled within CONSTELLATION has been overhauled, resulting in a more consolidated, and overall simpler API.

  • The most notable change is the introduction of “Schema Concepts” which collect related attributes, vertex types and transaction types into conceptual groups which can then be registered to a schema. Schema concepts will replace “Attribute Providers”, “Vertex Type Providers”, and “Transaction Type Providers” and are now hierarchical by default, making it easier to extend an existing concept.

  • Other changes include the simplification of “Schema” and “Schema Factory”, and new utility classes for interacting with schema concepts, vertex types and transaction types. In addition to this, we also now have a new convention where schemas should no longer extend each other, but rather inheritance should be limited to schema concepts.

• Improved performance of IconManager and added new icons, BAGEL_BLUE, BAGEL_GREY and CHART.

• Improved the Scripting View API by adding support for LINK and EDGE types.

• Moved the WhatsNewProvider from au.gov.asd.tac.constellation.core.tutorial.whatsnew to au.gov.asd.tac.constellation.core.whatsnew.

• Updated CoreImportExport now using Apache Commons CSV to parse CSV files.

Changes in May 2016

• Added a new module called CoreMapView which contains the Map View framework.

• Added versioning to attribute description classes.

• Fixed various bugs.

• Fixed a dormant graphics bug.

• Improved the Rule.executeRule method by forcing it to take a copy of the graph.

• Renamed the ResetPlugin class to ResetViewPlugin.

Change in February 2016

• Added an icons API so that developers can add custom icons programmatically using the IconProvider class.
