We have released version 3.6.3 of WPF Diagram control. It contains the following new features and improvements:

Lasso zoom tool
The control now supports several ways to zoom using lasso tool:

• Set the Behavior property to Zoom to always draw zoom lasso.
• Set the Zoom flag for one of the keys in ModifierKeyActions to let users draw zoom-lasso with respective modifier key pressed and the left mouse button.
• Assign Zoom value to RightButtonActions or MiddleButtonActions property to zoom using respective mouse button.

Layout improvements

• Automatic layout classes now process DiagramLinks connected to TreeViewItems.
• Set CompactLaterally property of LayeredLayout to create more compact layouts.

Miscellaneous

• ImageAlign supports new FitLeft, FitTop, FitRight and FitBottom alignment styles, which resize Image to fit node's boundaries and align it to respective border.
• The InitializeLasso event lets you customize appearance of selection lasso before it shows on screen.

API changes
The Behavior property setter no longer clears current selection. Call the SetBehavior method with true argument instead if you need selection cleared too.
