We have released version 5.6.4 of FlowChart.NET. It adds several customer-requested features and small improvements:

Link auto-snapping
Now links can automatically connect to the nearest diagram node without the mouse pointer reaching the node. This is enabled by setting the AutoSnapLinks property. The maximum distance at which auto-snap works can be specified through AutoSnapDistance. The LinksSnapToBorders property, which implemented similar functionality when the mouse is directly over a node, has been removed.

Components serialization
CompositeNode components are now automatically serialized when saving in binary or XML format. It is also possible to serialize custom components by overriding the SaveTo, LoadFrom, SaveToXml, LoadFromXml methods of ComponentBase. Saving all components along with their attributes could lead to a lot of wasted space for node types derived from CompositeNode that have the same component hierarchy. In such scenarios, override the SerializeComponents method and return false to stop component serialization, and save only the relevant node properties by overriding the SaveTo, LoadFrom, SaveToXml, LoadFromXml methods of CompositeNode.

Miscellaneous
~ WmfExporter now also renders the LaneGrid in the exported WMF drawing.
~ GetNearestNode returns the node that is closest to the specified point.
~ NodeClicked and LinkClicked are raised for items shown in DiagramView3D.
~ 3D positions of items specified via LayoutTraits[View3D.Position] are now serialized, both in binary and XML format.
~ GetProjectionOrigin method added to DiagramView3D.
