We have released version 1.3 of DiagramLite. It contains the following new features:

Undo / redo support
If the UndoEnabled property is set to true, DiagramLite tracks changes done on the diagram and allows undoing and redoing them later by calling the Undo and Redo methods respectively. Multiple changes could be recorded as a single undoable operation by enclosing them between StartCompositeOperation and CommitCompositeOperation calls. It is also possible to create custom undoable operations by deriving from the Command class and calling ExecuteCommand with the custom command as argument.

NodeListView control
NodeListView implements a palette -like control that lets the user create new nodes on the canvas via drag-and-drop. Its elements can be instances of any DiagramNode -derived class, including custom node types, as long as they implement the Clone method.

Miscellaneous
- Joins between segments of Cascading or Polyline links can be drawn as arcs by setting the RoundedLinks and RoundedLinksRadius properties.
- Grid points can be drawn as crosses by setting GridStyle to Crosses.
- Set the GridDashArray property to specify a custom dash style for grid lines.
- Size property added to the AnchorPoint class.
- The control sets the mouse cursor to show what operation would be started at the current mouse position.
TextBrush property added to the DiagramLink class.
- The control's assembly is now called MindFusion.Diagramming.Silverlight.dll;
