Release 11.0.0

Date	August 1, 2019
Status	Beta

Overview

Tom Sawyer Visualization, Java Edition, Release 11.0.0 adds many innovations since Release 10.0.0.

Tom Sawyer Visualization has been extended with an improved node growth model to better handle inside connector labels, connector constraints to control the order and positioning of connectors, the ability to rotate connector labels, and advanced swimlane support. Connector support has been improved to include fixed-size connectors with slope-end routing, variable-sized connectors that automatically grow with the number of edges that are attached to them, and connectors nested within other connectors. These additional forms of connector support allow for more customized drawings with complex structures. In addition, layout of connectors takes into account the labels of incident edges and connector labels and allows the connectors to grow accordingly.

In addition, this release brings significant performance improvement across all of the layout styles.
