Release 2.1.0

Overview

This release upgrades the bundled pilot implementation to version 2026-03 and improves support for the SysML v2 graphical syntax, including rendering of n-ary connections. This release also supports improved edge and node spacing and ortholinear diagramming to preserve orthogonality of edge routing upon drop.

Tom Sawyer SysML v2 Viewer has been updated to use Tom Sawyer Perspectives 13.6.0, including improved aspect ratios for expanded nested drawings in Orthogonal layout.
