We are starting beta tests of Flowchart.NET v5.6. The new features are:

Components
A new UI component system is now available for use in diagram nodes. The components represent graphical widgets similar to controls, which can be arranged in hierarchies and added to the diagram through instances of the new CompositeNode class. Flowchart.NET comes with various built-in components, such as layout panels, edit and button widgets. It is also possible to create custom component classes. Component hierarchies can be defined and loaded from XML, very much like WPF/XAML. A new tutorial section has been added to the help file describing various component features in a step-by-step examples.

Miscellaneous
~ SvgNodes now support SVG text and marker elements.
~ NodePointed and LinkPointed events are raised when the mouse hovers over a diagram item.
~ The Ruler.InchDivisions property specifies how many minor divisions to display when Unit is set to Inch.
