    Key Features

    • Scheduled and External Triggers: Create reusable scheduled triggers applicable across multiple flows and define external event sources that listen to events outside the ServiceNow AI Platform, triggering flows accordingly.
    • Automatic Saving and History Management: Flows, subflows, and actions are saved automatically during editing. Users can view and manage historical versions to copy, restore, or delete past configurations.
    • Conversational Enhancements: Create multiple skills for conversational subflows and actions, configure default Large Language Models (LLMs) for metadata generation, and display specific error messages to improve conversational clarity.
    • Flow Execution Improvements: Flows can pause and wait for email replies, and subflow execution stages are visible within parent flows for better monitoring.
    • AI Integration: Support for Now LLM Long Term Stable (LTS) models enables AI-powered flow generation and summarization. AI agent actions use flow data to run agents and handle their outputs within flows.
    • UI and Accessibility Updates: Introduction of the Coral theme as the default UI, a dark theme option, enhanced flow recommendations, improved debugger launching, and accessible canvas components supporting zoom and reflow for users with low vision.
    • Event Sources Menu: A new menu under the Integrations tab allows management of external event sources directly within Workflow Studio.

    Important Considerations for ServiceNow Customers

    • Workflow Studio is available and updated via the ServiceNow Store; customers should update the app to access Zurich features.
    • Customers upgrading from the Washington DC release might need to restore the "save as you go" functionality if previously disabled manually.
    • Workflow Studio is active by default as part of the ServiceNow AI Platform.

    Practical Benefits

    With these enhancements, ServiceNow customers can design more flexible, reliable, and AI-augmented workflows that integrate external events and conversational capabilities. Automatic saving and version history improve efficiency and reduce risks during development. The UI and accessibility improvements ensure a better user experience for diverse users.

    Important information for upgrading flows, subflows, and actions to Zurich

    An earlier version of the save as you go feature was released and withdrawn from the Washington DC release. If you're upgrading from the Washington DC release, you might have manually turned off the save as you go features by setting a system property. To restore the save as you go features, see Restore save as you go functionality.

    New in the Zurich release

    Create and manage external event sources
    Create an external event source on your ServiceNow instance that listens to events occurring in an application or system outside of the ServiceNow AI Platform®. Based on the external event source, you can define one or more external trigger definitions in your instance and then associate the external trigger definitions with the external event source. When an event that you specified in the external trigger definition occurs, the external trigger definition executes one or more flows. You can update or remove external event sources that you create.
    Create a domain-separated saved external trigger
    Create a domain-separated saved external trigger. Configurations that you make to the trigger are auto-saved. After the trigger is published, you can edit only the Label field values.
    Create a reusable scheduled trigger
    Create a scheduled trigger that starts your flow when you need. Use the trigger across your flows.
    Create a skill for conversational subflows and actions
    Create a skill for the conversational subflow and action and make the skill discoverable in conversations. You can have multiple skills for the same subflow or action.
    Enhancements in the subflow and action conversational settings
    To make the error messages more useful in a conversation, you can show specific error messages from the subflow or action rather than showing generic error messages. Additionally, if you override an input with reference, you can apply a filter to limit the number of records in the Reference field.
    Make a flow wait for an email reply
    Pause a flow until an email reply is received to an outbound email record
    Show subflow stages in a parent flow
