We have released version 2.8.2 of WpfDiagram. It adds the following new features and improvements:

Rotation improvements
~ Attached nodes can rotate together with their master node if the group's FollowMasterRotation property is set to RotateChildren.
~ The Text of a ShapeNode can be rotated independently from the node by setting the TextRotationAngle property.
~ Fixed a bug where links did not follow the rotation of their target TreeViewNode.
~ The scroll buttons shown in the caption bar of a TableNode can now be used when the table is rotated.

Miscellaneous
~ The SaveToXml method now saves the definition of a custom Shape if a node's Shape has not any Id specified.
~ If NegatedY is set, the vertical Ruler scale displays negated Y coordinates.
~ The Ruler control scales now start from the origin of the diagram's Bounds instead of (0,0).
~ Fixed a bug where GroupAnchorStyles attachments did not preserve the correct distance for some values.
~ The TextBox control used for in-place editing now wraps text to multiple lines by default.
~ The Diagram control can be automatically added to the Visual Studio toolbox by the installer.
