SysON 2026.7 and 2026.9 continue to expand SysML v2 modeling capabilities while making everyday modeling more fluid and expressive. Across these two releases, we improved expression editing, behavioral and requirements modeling, expanded the range of SysML v2 concepts available in diagrams, and made diagrams more representative of the complete model. These releases also highlight the growing invol...

Ce retour d’expérience est issu d’échanges avec une équipe d’Architecture d’Entreprise d’un grand service public français. Pour des enjeux de confidentialité, l’organisation et les interlocuteurs ont été anonymisés. Comment maintenir une cartographie fiable d’un système d’information composé de plusieurs centaines d’applications, tout en donnant aux équipes de transformation la liberté nécessaire ...

What if your Capella architecture could go straight into simulation? If you’ve ever designed a system architecture in Capella and wished you could simply press play to see how it behaves, let’s discover the Capella-Simulink® Connector 0.2.0 . As a result of a joint effort between Obeo and Thales , this connector is now available in Open Source . The Capella-Simulink Connector creates a practical b...

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 a...

For more than a decade, the MBSE Capella tool and the Arcadia method have helped systems engineers address the complexity of designing large and critical systems. Today, the systems engineering landscape is entering a new phase, shaped by two major evolutions: the emergence of SysML v2 and the growing adoption of web-based engineering environments. At Obeo, we believe that the principles that made...

 Capella 7.1.0 is more than a new release. It marks the first concrete milestone since Obeo strengthened its commitment to Capella and became actively involved in shaping and developing its future. Today we are proud to unveil the first results of this new momentum: Capella 7.1.0 , bringing stronger foundations and new capabilities to the platform, together with the Capella-Simulink® Connector Add...

Note: this message covers both the changes in Sirius Web 2026.5.0 and Sirius Web 2026.7.0 . Since Sirius Web 2026.3.0, we continued improving the modeling experience with a strong focus on richer diagrams, smoother day-to-day workflows, and a more robust platform.  This release introduces new diagram capabilities such as decorators, configurable layouts, and palette improvements, while making comm...
