CanvasComponentthat moved the viewpoint too much when changing the zoom property.
@GraphMLeven if the
GraphML#singletonContainersproperty was not set.
TextEditorInputMode: The size calculation for the editing
#TextAreawas fixed to respect all properties of the
#LineBreakRecognizerno longer results in two new lines each time
DefaultLabelStyle: Fixed line breaks when text wrapping is enabled.
#updateVisualto take all style properties into account when determining whether or not the visualization has to be re-created.
AbstractJComponentStyle: Fixed a bug that prevented serialization of the
#ContextLookupproperty after obfuscating the library.
XmlWriter: Fixed JDK 9 only additional, undesired whitespace when writing
HitTestRadiusproperty instead of view coordinates:
ICanvasContext.createCanvasContextwhen passing a
CanvasComponent, but no hit test radius.
IInputModeContextpassed to adjacent handles when moving a bend handle.
InteriorStretchLabelModel#getMinimumNodeSizenow uses the correct insets for width calculation. Previously the top insets were erroneously used for the width.
NodeStyleStripeStyleAdapter#updateVisualmethod always created a new visual by delegating to the
#InputModein a key event handler no longer throws an exception.
MapperRegistry#addMapperno longer throws an exception when trying to replace a mapper for an existing key.
NinePositionsEdgeLabelModelnow disappear when the owner edge has no visible edge path. This can happen for example when nodes are moved onto each other. Previously they appeared at unexpected locations, including the origin (0,0) and the upper left corner of the source node.
nullif there is no tangent at the requested position. Previously, it returned a bogus tangent.
FreeNodeLabelModel#INSTANCEare now serialized correctly to GraphML when not used as part of their parameters (e.g. within
IGraph#calculateLabelPreferredSizewhich was thrown when the label owner was not part of the graph, but all optional parameters have been passed anyway. In that case there was no need to fetch the appropriate
LabelDefaultsand thus the question of whether the owner is in the graph or not is irrelevant.
CreateEdgeInputModedid not always start correctly for quick gestures on slow devices.
CreateEdgeInputModedid not trigger the
#EdgeCreationStartedevent for programmatic initialization of the edge creation gesture.
#CurrentHandleproperty could not always be obtained during the

ViewportAnimationthat sometimes moved the viewport a bit before the animation started.
DropInputModewhich occurred if a drag enter was recognized while another drag action was still running.
CreateEdgeInputModeno longer fires gesture cancel events if it has not been started before.
StripeDropInputModeno longer calls
StripeDropInputMode#ItemCreatedevent was not raised.
GeneralPath#isVisibleoften returned true for invisible paths.
UndoEnginenow uses the end time of the previous undo unit for automatic bracketing instead of the start time. This improves auto-bracketing to work as intended for undo units spanning a time greater than
Rectangle2D#contains(Rectangle2D)method. As a consequence, the results of various algorithms and automatic layouts could have been wrong.
PortPlacementStage: Fixed bug that caused
NullPointerExceptionwhen the ports of edges in the input graph were outside the node bounds.
BusRouter: Fixed rare
NullPointerExceptionthat could be triggered if there are buses with both fixed and movable edges at the same time.
AbstractLabelLayout: Fixed bug that the box returned by
AbstractLabelLayout#BoundingBoxwas not consistent with the bounding box of the oriented box (
AbstractLabelLayout#OrientedBox). This was the case when the mutable oriented box instance was changed.
LayeredNodePlacer: Fixed bug that caused node-edge overlaps for some configurations.
MultiPageLayout: Fixed bug that edge type
EdgeType#PROXYwas never used.
StraightLineerroneously rerouted all edges in the graph instead of just the ones that were required.
RuntimeExceptionthat could be triggered when the graph contained fixed edges (see
EdgeRouter#SphereOfAction) with very short segments.
IllegalArgumentExceptionthat could be triggered when the user specified both edge directedness (see
HierarchicLayout#EDGE_DIRECTEDNESS_DPKEY) and layering constraints.
OrthogonalLayout: Fixed rare bug that caused node-edge overlaps.
SimplexNodePlacer: Fixed rare
IllegalArgumentExceptionthat could be triggered when the input graph had a partition grid and
OrganicRemoveOverlapsStage: Improved adherence to the specified maximum duration.
HierarchicLayout: Improved port assignment for edges incident to group nodes that are routed directly (see
EdgeLayoutDescriptor#DirectGroupContentEdgeRouting). Previously, such edges were often reversed.
HierarchicLayout: Fixed bug that caused violation of specified
PortCandidates of edges with labels with preferred placement specifier
LabelPlacements#AT_TARGET_PORTwhen using an orientation other than top-to-bottom.
SeriesParallelLayout: Fixed bug that caused misplaced edge labels for graphs containing only a single edge.
HierarchicLayout: Improved adherence to the specified maximum duration by applying a suitable runtime restriction to class
PortCandidateOptimizer. Previously, this class didn't have any runtime restrictions.
OrthogonalLayout: Fixed rare bug that caused overlapping nodes.
OrthogonalLayout: Improved from-sketch mode (see
UseSketchDrawing) in conjunction with node labels or node halos. Previously, in the presence of the mentioned elements, the layout results did not always correctly resemble the sketch drawing, even if it was a good sketch.
HierarchicLayout: Fixed bug that caused that property
HierarchicLayout#ComponentArrangementPolicywas not correctly considered when there are undirected edges (see
HierarchicLayout: Fixed bug that lead to edge ports lying outside the node boundaries when using the edge thickness feature (i.e. edges with thickness greater than zero, see
HierarchicLayout#EDGE_THICKNESS_DPKEY) together with a (rather large) grid spacing value and the default port assignment
HierarchicLayout: Fixed bug that caused unnecessarily large layer distances in case that there exist empty partition grid rows with a minimum row height.
HierarchicLayoutwith partition grid: Fixed bug that in some cases caused an
IllegalArgumentExceptionwhen the layout algorithm was configured to stop after the layering or sequencing phase (see
DefaultNodePlacer: Fixed bug in
DefaultNodePlacer#MinimumLastSegmentLengththat caused that the value of
TreeLayout: Fixed bug in
DefaultPortAssignmentthat caused a memory leak.
TreeLayout: Fixed bug in the integrated edge labeling feature that caused that multiple edge labels were not always ordered correctly along the edge with respect to their preferred placement setting (i.e., place at source, center or target preference). For example, a source label should always come before a target label in the direction of the actual edge flow.
polyline.EdgeRouter: Fixed bug that sometimes caused a violation of the minimum first or last segment length if they were set to relatively large values.
OrthogonalLayout: Fixed rare bug that caused non-orthogonal line segments and bad edge end points.
CreateEdgeInputModenow triggers the
EdgeCreationStartedevent for programmatic edge creation with the
HierarchicLayout: Added support for port grouping, see
PortConstraintKeys#TARGET_GROUP_ID_DPKEY. Edges are bundled at their ports, but routed independently.
HierarchicLayoutnow allows to specify the directedness of edges, see
HierarchicLayout#EDGE_DIRECTEDNESS_DPKEY. This new feature enables to, for example, support mixed graphs that contain both directed and undirected edges: While for directed edges the layering step tries to find a solution where the source of an edge is placed above the target (with respect to the main layout direction), for undirected edges the direction doesn't matter and the edge may also be inserted as same-layer edge. This feature also enables to force some edges to specifically point against the main layout direction.
HierarchicLayout: Added support for edges with a specific thickness. Minimum distances in the layout will consider these thicknesses, see
LabelPlacements: Added preferred placement specifiers
#AT_TARGET_PORTfor edge labels which express that the label should be placed directly at the source/target port of the edge. Currently, the specifiers are only considered by the integrated labeling of the
HierarchicLayoutand can be specified with property
OrganicLayoutnow supports the detection of regular substructures in the graph (see methods
#setParallelSubstructureStyle(ParallelSubstructureStyle)and applies a specific layout style to them such that they can be better recognized.
TreeReductionStage: Added possibility to specify a custom labeling algorithm that places labels of non-tree edges. Now, users do not need to take care of such edge labels themselves after using a tree layout algorithm on a non-tree input graph in conjunction with the reduction stage. See properties
SeriesParallelLayout: Added possibility to specify a custom labeling algorithm that places labels of non-series-parallel edges. Such labels are now automatically handled. Users do not need to handle them after running the algorithm with a non-series-parallel input graph. See properties
IGraph: The default methods
#applyLayout(ILayoutAlgorithm, LayoutData)have been added.
FilteredGraphWrappernow no longer queries the node and edge predicates as often.
IMapperRegistry: Several overloads for the
#create*Mappermethods have been added that take more specific tags but allow to omit the keyType parameter.
#morphLayoutconvenience methods have been added that run a layout on the graph of the component and animate the results.
GraphComponent#GraphMLIOHandlerhas been added to set a custom
GraphMLIOHandlerto be used by the IO commands and convenience IO methods. Previously the lookup of the class needed to be decorated.
GraphComponent: The overloads
#exportToGraphML(java.io.Writer, java.net.URI)have been added.
Animator: A getter for the
CanvasComponent, which had been passed to the constructor, was added.
VoidStripeStyleRendererhave been changed to the concrete types instead of the interface types (e.g.
IconLabelStyle: A constructor has been added that only takes a custom renderer as argument.
DefaultPortCandidateDescriptor, which is used to visualize
IPortCandidates, now provides static
ResourceKeyfields that are used to lookup
IVisualTemplates for the different states of
IVisualTemplates can be used by either registering them via
CanvasComponent#putClientPropertyor by the new convenience method
CreateEdgeInputModenow respects the settings
GraphSnapContext. It also handles grid snapping according to the configuration for snapping.
#addXamlNamespaceMappingmethods for easier control of the XML namespace for certain types.
GraphMLIOHandlerhas two new events,
#QueryNamethat allow for fine-grained control over XML namespace writing and parsing for certain types.
GraphMLIOHandler: The overloads
#write(IGraph, java.io.OutputStream, java.nio.charset.Charset, java.net.URI)and
#write(IGraph, java.io.Writer, java.net.URI)have been added.
GraphMLParser: The overloads
#parse(IGraph, InputStream, IGraphElementFactory)have been added.
GraphML: The performance for parsing java enums and
FlagsEnumshas been improved.
GraphML: Parsing java enums and
FlagsEnumshas been refactored and now respects
HierarchicLayout: Slightly reduced the number of bends when integrated edge labeling is enabled.
HierarchicLayout: Fixed unstable from-sketch behavior for non-default layout orientations when group nodes are folded or expanded. Applies to orientations
LayoutOrientation#BOTTOM_TO_TOP. Geometry information registered with data providers with keys
HierarchicLayout#ALTERNATIVE_EDGE_PATH_DP_KEYis now automatically rotated according to the specified layout orientation.
HierarchicLayout: Improved support for
PortCandidates at group nodes. Previously, they were only obeyed if there was just a single candidate defined, which also applied to the opposite node (not necessarily a group node). Now, out of the given candidates, one is selected and considered for the routing. Still, fixed candidates are treated like free ones and are not supported at the side of group nodes.
HierarchicLayout: Routing of grouped edges that connect to nodes of different groups now assures that the whole bus segment remains outside the different group nodes. This avoids that group nodes get unnecessarily large and potentially makes drawings more symmetric.
HierarchicLayout: Improved edge grouping such that it is now possible to group incoming/outgoing edges as well as same-layer/backloop edges with common edges.
HierarchicLayout: Can now take the original edge route into account to determine the route of a self-loop.
MultiPageLayout: Added new option
#StrictClusterSeparationEnabledthat allows to specify whether or not nodes with different cluster IDs may be placed onto the same page.
AspectRatioTreeLayoutnow support custom selection of the root node of the tree.
BalloonLayout: Interleaved child placement now works in conjunction with from sketch-mode and custom child order comparators. This means that the settings
#Comparatorare no longer ignored when enabling the interleaved placement mode (see
TreeLayout: Now take into consideration the minimum group node size specified by the user with a
IDataProviderregistered with the graph with key
SeriesParallelLayout: Now takes into consideration the minimum node size specified by the user with a
IDataProviderregistered with the graph with key
EdgeRouterwhen routing edges that have
OrthogonalSegmentDistributionStageand thus also
ChannelEdgeRouterwhich by default uses the mentioned stage as edge distribution strategy.
ChannelRouter: Improved order of segments to avoid edge crossings when there are multiple segments that have one common end point.
PartialLayoutfor input graphs that feature a high number of large subgraph components. Does not apply for component assignment strategy
LayoutUtilities#applyLayoutnow supports layout of tables.
ItemMapping: The property
#Mapperis now automatically set on first read-access to the property, enabling more convenient use of the mapper without first having to instantiate a matching instance.
PartitionGridData: It is now sufficient to specify one of a row mapping or the column mapping. The unspecified one will automatically be set to 0, resulting in a single row or column being used.
TreeLayoutDatanow have an
EdgeLabelPreferredPlacementproperty which supports an
ItemMappingfor edge labels to provide a
PrefererredPlacementDescriptor. Can be used as alternative to mappers registered with
PlanarEmbeddinghas been added and allows to calculate and query an embedding of a planar graph.
IGraph#addLabelthat ignored an explicitly specified preferred size if folding is enabled.
FilteredGraphWrapper: The fail-fast mechanism to detect concurrent modification changes in the
IListEnumerablesdidn't detect all modifications correctly.
SandwichLabelModel: Fixed incorrect
DefaultValueannotation for some created parameters.
SmartEdgeLabelModel: An exception was thrown if the path of the corresponding edge contained bends that were close together or at the same location.
NinePositionsEdgeLabelModel: Fixed the placement for the positions
GeneralPath#equalsdoes no longer check for path equivalence (same coordinates etc.), but simply checks reference equality. This makes it consistent with the
#hashCodemethod. To check for path value equivalence, use the new method
#importFromGraphML(java.io.File)method to respect the
#ClearingGraphBeforeReadEnabledproperty. (All the other
#importFromGraphMLmethods already did so.)
ComponentOrientation#RIGHT_TO_LEFTis set on the
GraphOverviewComponent: Setting a new
#OverviewInputModeupdates now the
GraphModelManagerthat didn't update the child groups if a new
falsewas not respected when the graph changed or a group node was created first on a yet ungrouped graph.
IVisualactually has been removed instead of just before the removal.
NullPointerExceptionin the graph rendering code when items were removed from the graph during their style's
#updateVisualmethod. This could happen when removing graph items from a different thread (which is still not supported, but at least this particular case won't crash anymore).
GridVisualCreatorwith grid style
Controlkey anymore but the
Commandkey as modifier instead.
CreateEdgeInputMode: Fixed a bug that didn't show the edge preview when the edge would be created between a node and one of its ancestors or vice versa.
#EdgeCreatedevent triggered before the corresponding undoable edit was committed. This could result in a broken undo queue, if e.g. an animated layout was started during in the event listener. The event now triggers after the edit has been committed. With automatic undo unit merging, this should not make a difference for the end user, however from the perspective of the code there will be two subsequent edits, rather than one compound, if the code in the listener actually modifies the edge.
CreateEdgeInputMode: Fixed a bug that broke the edge preview after the input mode was uninstalled and reinstalled again.
ESC, the dragged bend was removed.
OverviewInputMode: Fixed a bug that could break the overview visualization if the overview has a specific very small width or height.
StripeDropInputMode: Fixed a bug that could result in nodes being moved to a wrong stripe when a new stripe was created or an existing one relocated.
NodeDropInputMode: Fixed a possible exception when snapping is enabled, but preview disabled.
SHIFTkey held down the node was erroneously reparented to the root.
FreeEdgeLabelModelcannot place the label correctly for self-loops. Labels previously always appeared at the port location in this case.
IBendSnapResultProviderfrom the lookup no longer leads to a crash when nodes or bends are moved.
ICommand#EDIT_LABELwould not work directly on labels when a
DefaultLabelStyle: Fixed vertical text alignment for instances with non-empty insets.
IconLabelStyle: Fixed a
NullPointerExceptionthat occurred when rendering the style while the
#Iconproperty is set to
@GraphML#contentPropertyof a class.
@GraphMLannotations for static fields.
ValueSerializerused for predefined
IArrows now also respects the
#addRegistryOutputMapper(String, String, Object, IEventListener)created multiple GraphML key definitions for the same mapper instance
@Obfuscationannotation to exclude the class from obfuscation. Excluding
Arrowfrom obfuscation is necessary for properly reading (and writing) GraphML files.
@DefaultValueannotations for the
SegmentRatioPortLocationModeland corresponding port location parameter instances.
HierarchicLayout: Fixed bug that caused a violation of the specified minimum distance or edge overlaps in the case of same-layer edges.
HierarchicLayout: Fixed rare bug that caused same-layer edge to cross through their source or target node, e.g., the port was at the top of the source node but the edge crossed through the source node to leave it at the bottom.
HierarchicLayout: Fixed bug that sometimes caused the route of back-loop edges with at least one endpoint incident to a group node to unnecessarily enter this group node.
HierarchicLayout: Fixed bug that sometimes caused superfluous bends in edge routes when integrated edge labeling was enabled.
HierarchicLayout: Fixed bug that caused that the directedness of edges incident to groups wasn't considered correctly (see
HierarchicLayout: Fixed bug that caused node-edge overlaps in conjunction with some complex edge grouping specifications.
RecursiveGroupLayoutwhen used with
HierarchicLayoutas core layout algorithm: Fixed
IllegalStateExceptionthat could be triggered when group nodes of the input graph have

CoreLayout) is an instance of class
SimplexNodePlacer: Fixed bug that caused overlaps between edges and nodes when enabling node compaction (see
#NodeCompaction) and having edges with either strong
OrganicLayout: Fixed bug that caused group nodes with zero height/width in the layout result. The bug appeared when having empty groups, group node insets smaller than one (defined via
GroupingKeys#GROUP_NODE_INSETS_DPKEY) and no minimum group node size specified (
ClassicOrganicLayout: Fixed bug that caused the algorithm to not consider the specified custom
IllegalArgumentExceptionthat was triggered due to
NaNvalues that could occur in case the input graph has a very large number of nodes.
RadialLayout: Fixed bug that caused that always all edges are bundled if bundling is enabled for at least one single edge. More precisely, property
EdgeBundleDescriptor#Bundledwasn't considered correctly.
CircularLayout: Fixed bug that in some cases produced self-intersecting edges when edge bundling is enabled.
SingleCycleLayout: Fixed bug that may lead to a
ClassCastExceptionif edge bundling is enabled and a custom node sequencer is specified (see
AspectRatioTreeLayout#ROOT_PLACEMENT_DPKEYis now of type
AspectRatioTreeLayout#SUBTREE_ROUTING_POLICY_DPKEYis now of type
AspectRatioTreeLayoutDatadid not register the correct values with the graph for the root placement and the subtree routing policy.

IsolatedGroupComponentLayout: Fixed bug that caused edge labels that intersect with group nodes even though option
EdgeRouter: Fixed rare
RuntimeExceptionthat appeared if there were fixed (see
#Scope) and grouped edges at the same time.
EdgeRouter: Fixed rare
IllegalArgumentExceptionthat was triggered when having multiple target port candidates, where at least one must be fixed. Furthermore, to trigger the exception it is necessary that the path search algorithm tries to perform an early exit due to maximum duration restrictions or a stop request via
EdgeRouter: Fixed bug that caused violations of minimum first/last segment lengths of grouped edges when using different edge layout descriptors and, second, made the layout algorithm remove a user-registered
EdgeRouter: Fixed rare node overlaps in conjunction with monotonic path restrictions (see
ChannelEdgeRouter: Fixed routing of self-loops that have both source and target end point at the same side of the node. Previously, when multiple such self-loops were present at the same node, the routing produced bad end points located outside of the node.
NullPointerExceptionthat occurred when the given maximum number of clusters was
NullPointerExceptions in some

#isIntegratedEdgeLabelingEnableddoes now always return
falseif the labeling algorithm is disabled (see
MultiStageLayout#isLabelingEnabled. In previous versions it was only required that an appropriate labeling algorithm was specified, but it was not necessary that it is enabled. Therefore, the integrated labeling state queried from the property might not have corresponded to what the layout algorithm actually did. The same behavior change applies for the following methods:
HierarchicLayoutmay now place source/target labels in layers that contain common nodes. In previous versions such labels were always placed in separate layers which often led to less compact drawings with superfluous bends.
#ALTERNATIVE_EDGE_PATH_DP_KEYis now automatically rotated according to the specified layout orientation. This fixes unstable from-sketch behavior in incremental layout mode when using an orientation other than top-to-bottom. User that
OrganicLayoutdoes no longer resize empty group nodes, possible ignoring a minimum group node size for them (see
GroupingKeys#MINIMUM_NODE_SIZE_DPKEY). The behavior with respect to empty group nodes is now in line with the behavior of other common layout algorithms.

LayoutStylesDemo: The bound restrictions of the Organic layout can now be specified explicitly.
LayoutStylesDemo: Fixed the configuration for the minimum node distance of the Organic layout that was not editable before.
Folding: Fixed a bug in the folding mechanism that could lead to an endless loop when loading a GraphML file containing
PathBasedEdgeStyleRenderer: Fixed bug that could leave visual artifacts when switching to an arrow that returned a
CanvasComponent: Fixed a bug in the mouse wheel scroll behavior that moved the viewport in the wrong direction when scrolling page-wise vertically.
java.lang.IllegalArgumentException: Comparison method violates its general contract!problems caused by calling
java.util.Comparatorimplementations that do not imply a total order.
HierarchicLayout: Fixed bug that caused a violation of the minimum first/last segment length for reversed/backloop edges which connect to group nodes.
HierarchicLayout: Fixed rare bug that may cause overlaps between labels and segments of edges with octilinear routes.
HierarchicLayout: Fixed possible infinite loop if there are critical edges (see
TreeLayout: Fixed possible group node overlaps in conjunction with some node placers, for example

DefaultEdgePathCropper: fixed an issue where
getIntersectionwould not be called when cropping an edge at the source end.
IInputModeContext: fixed a bug in
getGraphthat could cause a stack overflow.
PopupMenuInputMode: moved the default popup menu location one pixel to the right and one pixel down to prevent the mouse cursor from being positioned directly on the popup menu's border. (Mouse clicks on the popup menu's border do neither close the popup menu nor trigger any of the popup menu's entries.)
HierarchicLayout: fixed rare
AsIsSequencerfor edges incident to group nodes that have a sketch without bend points as well as port constraints.
HierarchicLayout: fixed bug that may cause non-orthogonal segments of grouped edges even though orthogonal edge routing is enabled.
HierarchicLayout: improved compactness of layouts that feature group nodes with insets and (group) nodes with halos (
NodeHalo). Previously, the specification of halos could enlarge the insets of group nodes by an unnecessary large amount.
HierarchicLayout: fixed an exception that sometimes got triggered when sequence constraints were used.

HierarchicLayout: Improved result if compact label placement is enabled (which is the default), see
SimplexNodePlacer.LabelCompaction. In previous versions the labels may have been placed in a stacked style even if this did not make the result more compact (e.g. if all labels are placed to the right of the edges).
GraphPartitionManager: Fixed functionality to hide edges when using methods
GraphPartitionManager.hide. Previously, edges were actually not hidden from the graph.
HierarchicLayout: Fixed distance between vertical (in a top-to-bottom layout) segments of same layer edges that connect to group nodes. This also applies to self-loops that connect to the top or bottom of a group node with both ends as well as same layer parts of other edges like back-loops.
HierarchicLayout: Fixed bug that caused the minimum edge-to-edge distance to be violated by edges with strong port constraints that cross each other.

CanvasComponent: Added an event
FitContentViewMarginsChangedthat gets invoked when the propery
#FitContentViewMarginshas been changed.
bower installand opening
CanvasComponent#FitContentViewMarginsis now initialized to (10,10,10,10) as mentioned in its documentation.
SerializationVisibilityannotation as well as the
SerializationVisibilityTypeenum that are used to customize the serialization behavior of properties are now public to work properly.
GraphMLannotations did not work.
CollapsibleNodeStyleDecoratordidn't handle the hit testing correctly when different button sizes for the collapsed and expanded state were used.
NodeStyleLabelStyleAdaptersometimes produced a
NodeStylePortStyleAdapterdidn't work well together with
AbstractComponentNodeStyleas inner style.
PortDefaultswasn't serialized correctly as 'AutoCleanup' due to a missing GraphML rename.
GenericPortLocationModelweren't serialized correctly.
ITable#setLabelModelParameterignored the provided style resp. label model parameter.
SeriesParallelLayout: Fixed possible
NullPointerExceptionwhen handling graphs with group nodes.
ParallelEdgeLayout: Fixed bug that caused wrong edge port coordinates.
SeriesParallelLayout: Fixed violations of the minimum first and last segment length and self-crossings of octilinear edges.
SeriesParallelLayout: Fixed bug that caused node-to-node or node-to-edge overlaps in the case where the graph contained group nodes and node/edge labels.
HierarchicLayout: Fixed bug that caused critical edges to not be aligned (see
BusRouter: Fixed rare
IllegalStateExceptioncaused by non-orthogonal edge segments.
TreeLayout: Fixed bug that occurs when edges with single port constraints are reversed during the layout.
Polyline.EdgeRouter: Fixed possible
NullPointerExceptionthat may appear if a specified
PortCandidatehas multiple directions.
OrganicLayout: Fixed a bug that may occur when using
FlagsEnummembers now respect
GraphMLannotations for renaming. Such members can't be read back in prior versions of the library. Reading older files with the current version still works.
This is the initial release of the 3.0 series that brings a modernized API, many new or improved library features and support for current Java language features.
