We have released version 5.0.5 of NetDiagram. It contains the following improvements and bug fixes:

Canvas mode improvements
~ RoundedLinks and RoundedLinksRadius properties are now supported in Canvas mode.
~ LinkCrossings and CrossingRadius properties are now supported in Canvas mode.
~ Behavior.Pan is now supported in Canvas mode.
~ client-side ClickedScript event now raised when users click unoccupied point of the diagram.

Visio2013Importer improvements
~ The Item argument of ImportItem event handlers is now pre-set to a DiagramItem instance created for the imported Visio shape, letting you avoid parsing some standard data such as Bounds or Text. You can either modify this item's properties, or replace it with a new instance of a different type.
~ Fixed a crash when a shape master does not have a name attribute (this happens with custom stencils).
~ Fixed a crash when theme1.xml is missing from the imported vsdx archive (this happens with files converted from old Visio versions to 2013 format).
~ Fixed a parse exception for some non-English locales.
~ Fixed a bug where one-segment connectors were imported at wrong positions.

Registered customers with an active upgrade subscription can download the licensed version from the clients area on our site.
