Please refer to the projects that I've attached in the previous topic, as I also have some issues with scroll and ruler alignment. Before the update Diagram was aligned at the center by default, with the scroll bar being attached to the right side of the ruler and coordinates of the ruler were bound to the diagram.
But in the latest version if I use DiagramView, it is aligned to the left, and if I change the alignment to center, the ruler coordinates will not synchronize, and the scroll bar will be attached to the diagram directly, not to the right side of the ruler.
Could you please tell me, how to get the same alignment as it was before the last version?

It would be also nice to know ETA of your next release.

Yeah, it works as expected. Thank you!

Try changing ruler's Unit:

<mindfusion:Ruler Unit="WpfPoint" ...
 

and I can't actually see this project changing diagram's width, so the diagram has default A4 size. You can change diagram's width by setting Bounds:

diagram.Nodes.Add(imageNode);
diagram.Nodes.Last().Move(random.Next(Bottom, Top), random.Next(Bottom, Top));

Debug.WriteLine(diagram.Bounds);
diagram.Bounds = new Rect(Bottom, Bottom, Top, Top);
Debug.WriteLine(diagram.Bounds);
