You may have to fix your existing SysON models/projects by your own means to still be able to open them with SysON. Please download all your models/projects before upgrading to 2024.9.0. The changes are:

Refactor and simplify the implementation of the Interconnection View diagram, the following classes have been deleted, renamed, or merged:

Switch to Sirius Web 2024.7.1: all diagrams must be deleted and created again, due to the fix of this Sirius Web bug.

Add tool to create an ExhibitState from a StateUsage, the following classes & methods have been deleted or modified to simplify the handling of ExhibitStates

Migrate frontend to MUI 5, if you contributed React components that use MUI, you should upgrade them to use MUI 5.

Ensure that dropped nodes are always collapsed, the following methods have been moved to support this feature

Fix Add Existing Elements tool for start and done actions, the following methods have been moved to UtilService to make them reusable by different services (they are now used by ViewNodeService and ViewToolService):

Fix an issue that revealed the documentation compartment when dropping an element on itself, the following method’s contract has been updated as part of the fix:

Allow to create an Action Flow View diagram on an ActionDefinition or ActionUsage in addition to Package, the tool Create Package is not available in Action Flow View diagrams anymore.

Switch to Sirius Web 2024.9.0

Switch to Spring Boot 3.3.1

Add a dependency to CycloneDX to compute the backend software bill of materials during the build

Prevent nested part to be rendered as border nodes in the Interconnection View diagram.

Fix an issue where a click on inherited members inside compartments was raising an error instead of displaying the palette.

Fix an issue where non-containment references in standard libraries weren’t correctly imported into the project’s editing context.

Remove owning Usage memberships from inherited memberships of Usages. Memberships of a Type are inherited via Specialization or Conjugation, not by composition.

Fix an issue that allowed to drop an element from the explorer or the diagram on one of its children. Doing so deleted both the dropped element and its children from the diagram, and could delete the representation if one of the element was the root element of the representation.

Fix an issue that made the direct edit not working on Constraint and Requirement elements.

Fix an issue that made the addExistingElements not work properly for start and done actions inside actions and parts.

Fix an issue on constraint expression name resolution that prevented from referencing elements in other containing namespaces than the direct owner of the constraint. It is now possible to reference an element in any of the containing namespaces of the constraint.

Fix an issue that deleted the content of an action when it was dropped from the diagram to an action flow compartment.

Fix an issue where it was impossible anymore to set the cardinality of an Element as graphical node through direct edit.

Fix an issue where ConjugatedPortDefinition labels were rendered as null instead of their actual name.

Fix an issue that made direct edit of names not working on nodes in the Interconnection View diagram.

Fix an issue that revealed the documentation compartment when dropping an element on itself. The drop isn’t allowed anymore, and a warning message is displayed.

Fix an issue that deleted feature typing specialization when nesting a PartUsage in a PartDefinition.

Fix an issue that prevented the drop of the root element of a diagram on its background.

Fix an issue that made all the elements references when imported by the SysMLParser.

The second one called "New ExhibitState with referenced State" shows a dialog allowing to select an existing State to associate to the new ExhibitState.

Display qualified names in diagrams nodes' labels in case of standard libraries elements.

Handle the representation of actors on the General View diagram. Actors are represented with a stick figure image, with their label displayed below the image.

Add support for edges between actors and their containing UseCase/Requirement in the General View diagram. The source of the edge (the UseCase or Requirement) can be reconnected to another UseCase or Requirement, but the target (Actor) cannot be reconnected.

Allow to select existing RequirementUsage and RequirementDefinition on Objective tool.

Add a check to make the build fail if a Cypress test contains it.only.

Improve the drop from the explorer to ensure that dropped nodes are always collapsed.

Display prefix keywords in labels of Definitions and Usages graphical nodes.

Ensure that dropping an element from the explorer on the diagram reveals the corresponding node if it is already on the diagram and hidden. A warning message is now displayed when attempting to drop an element which is already displayed and visible in the target container.

Ignore keywords order during direct edit of prefixes labels of Definitions and Usages graphical elements.

DirectEdit on graphical node or list item authorized only to modify keywords which can be displayed in each label.

The embedded syside-cli.js is copied in a system temp folder and executed from there (with node). But, if you encounter execution rights problem, you can still copy syside-cli.js in a place where you have the appropriate rights and use the org.eclipse.syson.syside.path application option.
