    Important Upgrade Information

    • Workflow Studio Installation: Installed automatically on instances starting with Xanadu, but as a ServiceNow Store application, Workflow Studio requires manual updates to access the latest features.
    • Automatic Dependency Updates: Starting with Washington DC Patch 3, updating Workflow Studio also updates its dependencies (Workflow Studio, Playbook, Decision Builder) automatically. Individual dependency updates or visibility are no longer available via the ServiceNow Store or plugin lists.
    • No New Updates in Yokohama: The Yokohama release includes no new features, changes, removals, or deprecations for Decision tables in Workflow Studio.

    Key Features Introduced in Xanadu

    • Create Decision Tables Directly in Flows and Subflows: Enables rapid addition of decision logic using inputs from the flow or subflow context.
    • Create Decision Tables in Playbooks: Allows managing complex business logic by adding Decision tables in Playbooks with the "Make a Decision - First Match" activity, using playbook inputs to control subsequent actions.
    • Ranking and Reordering Decision Table Rows: Provides control over the evaluation order of decision rules by typing new rank values and reordering rows to fine-tune decision logic flow.

    Enhancements and Usability Improvements

    • Theme Updates: Decision table UI was enhanced to align with standard ServiceNow AI Platform themes for consistent user experience.
    • Scrolling in Large Decision Tables: Improved usability by enabling scrolling within large decision tables while keeping headers fixed for better navigation.

    Localization Considerations

    The Localization Framework is integrated into decision tables; however, editing decision tables in Excel does not support localization. Consequently, instances using languages other than English cannot utilize Excel editing features for decision tables.

    Additional Notes

    • No features or functionality were removed or deprecated between Xanadu and Yokohama.
    • No updates regarding activation, additional system requirements, browser requirements, or accessibility were introduced in this upgrade path.

    Practical Impact for ServiceNow Customers

    When upgrading from Xanadu to Yokohama, you can expect a stable Decision tables experience with no new updates in Yokohama but benefit from the foundational enhancements introduced in Xanadu. To leverage the latest capabilities, ensure Workflow Studio is updated manually via the ServiceNow Store, noting that dependencies update automatically post-Washington DC Patch 3. The ability to create and manage decision tables directly inside flows, subflows, and playbooks simplifies workflow logic design and maintenance. Usability improvements like scrolling and UI theme consistency enhance user experience during decision table configuration.

    Xanadu

    Workflow Studio is automatically installed on your instance.

As of Washington DC Patch 3, updating Workflow Studio automatically updates all its application dependencies such as Workflow Studio, playbook, and Decision Builder.
