The SysML v2 Release repository contains the latest incremental release of the SysML v2 specification documents, example models and model library. It also provides instructions for user installation of SysML v2 Pilot Implementation editors. For developer installs, please see the development repositories also available from the Systems Modeling organization on GitHub.

The SysML v2 Submission Team (SST) was a joint team of over 200 individuals from over 80 industry, academia and government organizations, who worked together to develop the next major version of the Object Management Group (OMG) System Modeling Language (SysML). The goal was to deliver a SysML v2 specification validated by the user community, demonstrable with a pilot implementation and providing a smooth migration path for SysML v1 users and models.

In February 2023, the team submitted three specifications to OMG, which were adopted as beta specifications.

• Kernel Modeling Language (KerML), version 1.0
• OMG Systems Modeling Language (SysML), version 2.0
• Systems Modeling Application Programming Interface (API) and Services, version 1.0

These beta specification are now in the OMG finalization process, which is expected to be completed with the publication of corresponding formal specifications in 2024. The former SST development team plans to continue to publish incremental releases of the pilot implementation, in support of the work of the three finalization task forces, with the goal of eventually developing this into a reference implementation for all three specifications.
