Sirius Web 2026.9

With Sirius Web 2026.9, we build on our efforts to make every modeling interaction more consistent, efficient, and predictable.

This release focuses on two complementary goals: providing a unified palette experience across diagrams and trees, and refining the small interactions that matter when editing complex diagrams. It also gives application builders more control over how tools are organized and presented to users.

• A unified palette experience, now including connector tools
• More ways to customize palettes in Sirius Web-based applications
• Faster group actions for selected diagram nodes
• More precise lasso selection and fewer accidental moves
• Numerous fixes for more predictable diagram editing
