FlowChart.NET version 6.3.4 adds the following new features and fixes:

Street maps
MapNodes can render street maps in OpenStreetMap format. Call MapContent.FromXml to load an .osm file. The pens and brushes used for drawing the map are stored within the StreetMapPens and StreetMapBrushes collections in the static StreetMapFeatures class. You can define additional pens and brushes for drawing and painting certain map features by using the MapContent's AddPen and AddBrush methods.

Miscellaneous
~ distribution now includes a set of digitally-signed assemblies;
~ undo/redo records for in-place edit operations are now created automatically;
~ CompositeNode supports vertical scrolling in EditComponent (only via keyboard);
~ support for FromPage and ToPage properties of PrinterSettings;
~ CreateBarcodeNode methods added to Diagram.Factory;
~ improved speed when dragging large hierarchies of grouped nodes;
~ fix for not restoring Column.AutoWidth value when cancelling or undoing TableNode column resize operations;

This release drops support for .NET 2 and the minimum supported .NET framework version now is 3.5.
