The new version introduces improved support in the Hierarchic layout algorithm to maintain a user's mental map when collapsing and expanding group nodes in a diagram.
Also, it supports 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 new version the feature set of the automatic layouts in the yFiles for Java 2.x technology line is on a par with yFiles for Java 3.0, which 2.13 is available in parallel to.
