Discover SysON 2026.1.0

[AxelRICHARD]

On behalf of the team and all the contributors, we are pleased to announce the release of SysON 2026.1.0.

This new version brings several enhancements and new features:

• Duplicate object: a duplicate action is now available in the Explorer view to duplicate semantic Elements. It is also available from the palette to duplicate a graphical node and its semantic Element.
• Connection usages: in diagrams, a new graphical edge tool is available to create binary ConnectionUsage between Usages.
• Improved direct edit: when using direct edit tool on an AttributeUsage value, you can more easily use symbols from the SI standard library.
  For example you had to import the SI library to use N and m symbols like this attribute t1 = 10.0 [N*m] or prefix the symbols if the library was not imported like this t1 = 10.0 [SI::N*SI::m].
  We are now auto importing the library automatically if we detect the use of a symbol from the SI library.
• New tools: among many new tools, on General View diagrams, it is now possible to create Comment graphical nodes from the diagram background.
• Improved performances: improved performances of textual export on big SysMLv2 models.

You can find the full list of bug fixes, improvements and new features in the Release Notes.

Also please remember only YEAR.MONTH.0 versions are stable and suitable for production deployments.
Other versions, such as intermediate releases, are intended solely for testing purposes.
