We have released version 4.0.6 of WPF Diagram control. It contains the following new features and improvements:

.NET 8 support
The distribution now includes assemblies and sample projects for .NET 8. Locally installed assemblies do not appear automatically in Visual Studio toolbox at this time; you can either add references manually or through Nuget package manager.

UI virtualization improvements

• The Overview control now virtualizes items when its ScaleMode is different from FitAll.
• Large ContainerNodes that cover several screens now create presenters only for Children inside current DiagramView viewport.

Miscellaneous

• Drag-and-drop ghost image now displays custom node templates.
• Fix for item interactions starting on mouse-down event, instead of first mouse-move as in version 3 of the diagram.

Installer for the latest version can be downloaded here, or from the clients area on our site:

Updated assemblies are also available as MindFusion.Diagramming.Wpf NuGet package.

Enjoy!
