Released on: June 26. 2026


The 2026x Refresh1 release introduces improvements to client-side collaborative modeling capabilities. Partial Project Usages is now out of the technology preview phase and offers a smoother user experience for defining usage scope. Additionally, the feature for saving projects to an earlier version has been improved so that all used projects are saved together with the open project, and Teamwork Cloud projects can now be saved to an earlier version as .mdzip files.

Partial Project Usages

We are excited to announce that Partial Project Usages is now out of the technology preview phase, featuring a significantly improved overall user experience. As in previous releases, the feature allows you to define the usage scope by selecting a specific part of a project, and enables seamless switching between full and partial usages as well as easy adjustment of the usage scope at any time.

Partial project usage

Saving Projects to an Earlier Version

The previous release introduced the ability to save projects to an earlier major version—for example, from version 2026x to 2024x—making it easier to collaborate with teams using older versions of the modeling tool.

In version 2026x Refresh1, this functionality brings the following improvements:

  • If your project uses other projects, all used projects are saved together with the open project.
  • You can now save Teamwork Cloud projects to an older version as .mdzip files without first saving them locally.

SysML v2 Project Migration to Version 2026x Refresh1

The new release supports several options for migrating SysML v2 projects to version 2026x Refresh1. You can migrate all or selected projects on the Teamwork Cloud server in bulk via the Collaborate menu, or migrate standalone Teamwork Cloud or local repository projects by opening them and agreeing to update standard libraries.
