Tom Sawyer Perspectives, Java Edition

Releases

Release 13.2.0

DateFebruary 26, 2025
StatusGeneral

Overview

This release highlights improvements to the Modern web client framework, which is now the default framework for Perspectives applications, featuring rearranged default toolbars in our views and updated action icons. Key updates include that our chart and timeline views now have a React-based underlying framework. Other improvements are: REST support, Print Preview support, Cancel Layout operation, invokable view dialogs, and HTML dialogs. New tutorials show how to use Tom Sawyer Web Components in Angular or plain HTML web applications. End users now have the ability to enter custom Cypher or Gremlin queries directly in their application. Performance speed of schema extraction has been significantly improved for graph databases.

Hierarchical layout has been improved to reduce edge crossings up to 30-50% on average, and also improved node placement and edge routing given the flow of edges in the drawing. The implementation of Closeness Centrality has also been improved for disconnected graphs.

Perspectives has been upgraded to Spring Framework 6.2.2 and Spring Boot 3.4.2. Also, many third-party libraries have been updated to eliminate potential vulnerabilities.
