Tom Sawyer SysML v2 Viewer, Web Edition

Release 2.0.0

Overview

This release upgrades the bundled pilot implementation to version 2025-12 and improves support for the SysML v2 graphical syntax, including rendering of Time Slices, Snapshots, Portion Membership elements, and Require Constraints compartments. This release also has several layout improvements including slope-end routing to ports, improved expand and collapse behavior, and an option to consider directions of edges in sequence diagram layout.

Tom Sawyer SysML v2 Viewer has been updated to use Tom Sawyer Perspectives 13.5.0. Layout improvements enhance clarity and reduce visual disruption when expanding nodes. Disconnected nodes now have improved placement upon the expansion of nodes. In addition, incremental layout is applied more effectively, minimizing unnecessary movement so existing nodes stay closer to their original positions. You can see more details about Perspectives 13.5.0 here. Also, many third-party libraries have been updated to eliminate potential vulnerabilities.
