JDiagram version 4.1.4 contains the following new features and fixed bugs:

Resize table columns and rows
Columns and rows of a TableNode can now be resized interactively if its AllowResizeColumns or AllowResizeRows properties are enabled. In order to resize, move the mouse pointer to the border line on column's right side or row's bottom side until it shows resize cursor and start dragging. The control raises TableColumnResizing and TableRowResizing events to let you validate new size or prevent resizing some elements. The TableColumnResized and TableRowResized events are raised after the operation completes.

License keys
There is no separate trial build of the control's .jar file anymore. Instead, call the setLicenseKey method of DiagramView to disable the component's evaluation mode and stop displaying trial messages. setLicenseKey is static and you can call it just once before creating any views. License key strings are now listed on the Keys & Downloads page at MindFusion's customer portal.

Miscellaneous
~ NodeConstraints.KeepInsideDiagram prevents a node from leaving diagram boundaries during user interaction (the older RestrictItemsToBounds property does not stop nodes from leaving diagram area but returns them to original position if dropped outside).
~ dashed selection frames are now drawn in two colors and should be visible on both the default white background and custom darker backgrounds. You can change the second dash color via HandlesVisualStyle.DashBackground property.
~ improved mouse capture for composite controls hosted inside ControlNodes.

Fixed bugs
~ fixed text clipping problem when magnifier is over TreeViewNode.
~ links to contained nodes were left visibly disconnected from them after deleting a folded ContainerNode.
~ lasso selection could not select strictly horizontal or vertical straight-line links when Selection.IncludeItemsIfIntersect is disabled.
