Release notes

2025.1.0

Key highlights

  • New palette in diagrams: The complete redesign of this contextual palette brings:

    • draggable it.

    • "Search Tool" section allowing you to quickly search and found element/tool you want to use

    • quick access to the latest element/tool used.

    • all elements/tools are organized in sections by their name.

New palette tool
  • New command palette: With "CTRL + k" or on the top right side of SysON, a search command window will be displayed to help you to quickly process any tool command.

For the moment, only "search element" command is available. But this will help you to quickly found any element in your model

Command Palette
  • New explorer view: Rework the structure of standard and user libraries in the Explorer view. The Explorer view now contains the following directories for libraries:

    • Libraries: top-level container for all the libraries used in the project

      • KerML: KerML standard libraries

      • SysML: SysML standard libraries

      • User Libraries: User-imported libraries

Libraries Directories in the explorer

Breaking changes

No breaking changes.

Bug fixes

  • Fix textual export of LibraryPackage: the exported file now correctly contains library package <Package Name> instead of package <Package Name>.

  • Fix an issue that made the expand action of the explorer not work on specific filter combinations. The explorer now correctly allows to expand elements when the Hide Root Namespaces filter is disabled and the Hide KerML/SysML Standard Libraries filter is enabled.

  • Fix an issue where some error messages were displayed when an element with implicit Specialization was selected and the Related Elements View was displayed.

  • Fix deletion of imported models from the explorer. Users can now delete imported library models (i.e. models with a LibraryPackage element), but they cannot edit them nor delete elements inside them. Imported models that do not contain libraries can be modified as regular models created in the project.

  • Ensure that a non-library imported model is not moved into the User libraries directory when a LibraryPackage is created in it.

New features

  • Handle imported package elements in diagrams.

Namespace import node
  • A new palette is available in SysON, all tools have been organized in sections.

New palette tool

This new palette contains a search bar, allowing to easily retrieve tools by their name.

  • New SysMLv2 Project Data Versioning-related REST APIs. The new endpoints are:

    • getCommits (GET /api/rest/projects/{projectId}/commits): Get all commits in the given project. There is only one commit per project in SysON for now, and its Id is the same as the project Id. It represents the current state of the project, without taking care of data created/updated/deleted since the creation of the project.

    • createCommit (POST /api/rest/projects/{projectId}/commits): Create a commit in the given project. There is only one commit per project in SysON for now, so the default implementation of this method does nothing.

    • getCommitById (GET /api/rest/projects/{projectId}/commits/{commitId}): Get the commit represented by its Id for the given project. There is only one commit per project in SysON for now, and its Id is the same as the project Id. It represents the current state of the project, without taking care of data created/updated/deleted since the creation of the project.

    • getCommitChange (GET /api/rest/projects/{projectId}/commits/{commitId}/changes): Get all changes of the commit represented by its Id for the given project. There is only one commit per project in SysON for now, and its Id is the same as the project Id. The default implementation retrieves all elements containing in the project, without taking care of data created/updated/deleted since the creation of the project.

    • getCommitChangeById (GET /api/rest/projects/{projectId}/commits/{commitId}/changes/{changeId}): Get the changes associated to the given change Id for the commit represented by its Id for the given project. There is only one commit per project in SysON for now, and its Id is the same as the project Id. The default implementation retrieves all changes containing in the project, without taking care of data created/updated/deleted since the creation of the project. The change Id parameter should be randomly generated but constant for an unlimited period. We decided to generate this Id from it’s commit Id and element Id, to be able to compute it.

Improvements

  • OccurrenceUsage#portionKind is now unsettable and its default value is null in the SysMLv2 metamodel to conform to the specification.

  • Improve the code in import module, by making it more generic. It now reports (on the server side) more messages to understand the scope of what is imported and the errors encountered.

  • Add support of OccurrenceDefinition and OccurrenceUsage in export from model to textual SysMLv2.

  • Remove 'New objects from text' contextual menu entry for libraries.

  • Allow to import .kerml textual files.

  • Remove 'New object' and 'New representation' contextual menu entries for libraries.

  • Remove Sirius Web default explorer. The SysON Explorer is now the default explorer for SysON, and the Sirius Web explorer cannot be used anymore.

    • Nested usages that are composite are connected by a filled diamond edge

    • Nested usages that are references are connected by an empty diamond edge

Nested Usage edge for composite and reference Usage

The first one called "New ExhibitState" creates a simple ExhibitState. 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.

Qualified names for standard libraries elements
  • Allow to select existing Action on Perform tool.

  • Allow to set measurement units via direct edit. It is now possible to configure the measurement unit for the value of an element, e.g. mass = 10 [kg].

  • Allow to select existing Type on Subject tool.

  • Display prefix keywords in label for Usage compartment element

  • Display multiplicity suffix property keywords in label for Usage element

  • Allow direct edit of prefix keywords and multiplicity suffix for Usage elements

    • Prefixing or not the name of an Usage attribute with direction or "abstract" or "variation" or "readonly" or "derived" or "end" (this order counts) sets its matching property with the correct value

    • Suffixing or not the name of an Usage attribute with "ordered" or "nonunique" (this order counts) sets its matching property with the correct value

  • Add support for constraint expressions in the general view. Constraints with expressions such as mass >= 10 [kg] are now correctly parsed and the corresponding semantic objects are created in the constraint.

  • Improve the support of root Namespaces in SysON documents.

    • Root Namespaces are now implicitly created at the root of SysON documents.

    • Creating an element at the root of a SysON document now creates it in its root Namespace.
