Hello,
I noticed that the NodeEditPolicy is gone. Is there a replacement policy for
deleting a node's connections?

The stategy of forwarding delete requests to other EditParts was
problematic, and was making it harder for people to learn GEF.
problems:
1) Outline view does not contain ConnectionEditParts, therefore you must
handle delete in the outline view using some other mechanism. Thus, it
probably makes sense to use the same mechanism everywhere, instead of two.
2) Filtering of connections in the graphical view would mean that certain
connections in the model don't have EditParts, so they wouldn't get deleted.
Of course we had to fix our logic example to work in both the outline and
the graphical view. See the class DeleteCommand in logic example. It still
has to traverse node->connections, but it does so in the *model*. I feel
that this is much safer and easier to understand than before. And, the same
process applies to both trees and graphical views.
