This version adds support for Sankey diagrams with their characteristic thick edges to the
Hierarchic layout and brings improved support in the Hierarchic layout algorithm to maintain
a user's mental map when collapsing and expanding group nodes in a diagram.
There is also new support for layout of regular substructures in the Organic layout style and
a new edge routing style in the Circular layout, Radial layout and the Tree layout algorithms,
where edge paths are bundled to prevent visual clutter in diagrams.
With this version the feature set of the automatic layouts in the 1.x technology line
of yFiles for HTML is on a par with yFiles for HTML 2.0.
