PAS 26.0 Release Notes

PAS 26.0 (19.01.2026)

Migration Note

With this release, the persistent state schema version is updated to version 17 (18.1 for MariaDB). This means that - once you have updated - a downgrade to an older Runtime version is only possible if the persistent state database is empty.

New Features

Administration

  • Kubernetes: New AI Agent Configuration Panel
    As with xUML services, the PAS Administration now offers to see and edit the service configuration of AI agent workloads. This section also shows in which service the agent has been created.

  • Kubernetes: AI Agent Overview in xUML Service Details
    The new AI Agents section has also been integrated into the details of xUML services, displaying all agents created within a service with their name and description. From here, you can open the new configuration panel for AI agents via a direct link:

  • Docker & Kubernetes: New “Update Runtime” Feature
    If you have multiple versions of our PAS Runtime available on your PAS installation, you now have the option to easily change the Runtime version used in an xUML service. Use Update Runtime in the service details to access the new user interface:

Designer

  • Automatically Applied Extension on Adapter Operation
    If you drag and drop an adapter operation like e.g. REST, OData, SAP RFC Operation onto an activity diagram, the necessary extension is applied automatically.
