Tom Sawyer Perspectives, Java Edition

Release 8.2.2

Overview

This release features added data integration support for JanusGraph and Stardog, as well as continued improvements to product quality and performance, with improved support for large graphs. In Graph and Data Visualization, the XML integrator updates data up to three times faster and commits data up to 100 times faster for large graphs. In web applications, rendering performance is up to twice as fast for large graphs, hit-testing is twice as fast, and the deletion speed of model elements is greatly improved for large models. It is now possible to resize columns within a table view in web applications. Additionally, there is improved labeling in symmetric layout.

Release 8.2.1

Overview

This release features continued performance tuning, improvements to product quality, and support for Apple macOS 10.14, Apache TinkerPop 3.3.3, and Neo4j 3.4.7. In Graph and Data Visualization, there is a 16% improvement in hierarchical layout performance, an 11% improvement in circular and symmetric layout performance, corrected hit-testing for rotated labels, and the automatic collapsing and expanding of tree nodes. In Graph Database Browser, there is a correction for reversed edge directions for Apache TinkerPop data sources. Release 8.2.1 also provides improved execution in Business Process and fixed links to Model-Based Engineering web projects so they can be shared and bookmarked.

Issues

• If you previously used orthogonal layout or hierarchical layout with orthogonal routing in your project, and updated that project to Release 8.2.0, the behavior of nodes being resized by layout might have changed. If you notice unexpected node resizing behavior in your application, contact Support for a resolution.
• Due to updates to security settings in Apple macOS 10.14, the Tom Sawyer Perspectives documentation does not load in Apple Safari Version 12.0. If Safari 12.0 is your default browser, open the documentation using a different browser, such as Chrome or Firefox.

Release 8.2.0

Overview

This release expands our data integration support with a new save-to-Neo4j capability and schema extraction for our SQL and Apache TinkerPop data integrators. Additional Graph and Data Visualization improvements include the addition of new graph analysis functions available from the Designer and improved performance for graph algorithm analysis integration.

This release brings improvements to orthogonal layout performance by up to 16% on server-class machines and improvements to drawing quality for nested orthogonal drawings. The number of crossings has been dramatically reduced for connectors with multiple edges per connector and nested connectors. Bend elimination and labeling have been improved as well.

Tom Sawyer Perspectives, Release 8.2.0 also includes new and improved features in Model-Based Engineering and Business Process. The ability to filter a diagram by its relationships has been added to both web and desktop applications, and the loading speed of Internal Block diagrams has improved by 20–30%. Model-Based Engineering diagrams are significantly more attractive with new color control options. In Business Process, you can add a service task for automated processing and a boundary event to handle an exception sequence flow.
