It is designed to assist in upgrade preparation and to highlight key capabilities introduced in Yokohama. Show full answer Show less ## Important Upgrade Information * **Role-Based Execution Details Access (Xanadu):** After upgrading, the `fdreadoperations` role limits users to basic execution details only. To grant full visibility of execution details including input configuration and runtime values, assign the new `fdreadoperationsall` role. * **No additional upgrade tasks required for Yokohama release.** ## New Features * **From Xanadu:** * Automatic generation of data pill values during flow creation to improve accuracy of flow triggers and action inputs. * Capability to run Workflow Studio actions and subflows directly from Now Assist conversations, integrating virtual agents with workflow automation. * Flow generation supports referencing specific tables via hash tags with auto-complete for smoother flow development. * Annotations showing how textual directions map to generated flow components, enhancing transparency during flow generation. * Control over user visibility of execution details through role assignments. * Support for signing and validating flows, subflows, and actions to ensure authenticity and integrity. * **From Yokohama:** * Create and edit flows directly within Now Assist when generating or enhancing applications. * Run published Now Assist skills from Workflow Studio actions with configurable inputs and outputs. * Compatibility checks for conversational suitability of actions and subflows, ensuring seamless integration with conversational interfaces. * Generate flows or subflows from process images using Now Assist, enabling visual process capture and automated flow generation. * View natural language descriptions of data used by flow components without opening their configurations, improving flow understandability. * Use generative AI to auto-generate skill and input descriptions for conversational actions and subflows. * Set and optionally hide default input values for conversational actions and subflows to streamline user interactions. * Support for new input data types in conversational actions and subflows, including Dynamic Choice and Array of Objects. * Receive automation type recommendations based on answers to guided questions, helping choose between playbooks, flows, subflows, actions, or data streams. * Debug flows and subflows in a dedicated Workflow Studio tab with breakpoints and step-through capabilities to analyze runtime values. * Save flow triggers for reuse across multiple application flows, with control over trigger visibility and conditions. * Pause flows awaiting a specific message via the Flow API and send messages to paused flows to resume execution. ## Changes * **Xanadu:** Flow generation now configures action and flow logic inputs using data pills, improving flow accuracy and automation. * **Yokohama:** Added natural language text descriptions for data used by flow triggers, actions, and logic blocks to enhance comprehension without configuration inspection. ## Removed Features * The system property `com.snc.processflow.reporting.iteration.lastn` controlling loop iteration reporting was removed; use flow execution settings records instead. * The user preference to include draft actions in available action lists was removed; custom actions must be published to be visible during flow design. * No removals occurred in Yokohama. ## Activation and Additional Information * Workflow Studio is active by default as part of the ServiceNow AI Platform in both Xanadu and Yokohama. * Keep Workflow Studio updated via the ServiceNow Store to access the latest features. * No additional or changed browser requirements or accessibility compliance levels beyond improvements in ARIA labels, keyboard navigation, and zoom support up to 400% for better usability in Yokohama. * No new localization considerations were introduced. ## Practical Outcomes for ServiceNow Customers * Enhanced security and role-based access to sensitive execution details protect data while allowing appropriate visibility. * Improved integration with conversational interfaces through Now Assist skills and conversational compatibility checks streamlines automation in virtual agent workflows. * Generative AI capabilities simplify flow documentation and conversational skill configuration, reducing manual effort. * Visual flow creation from images and enhanced debugging tools accelerate flow development and troubleshooting. * Reusable triggers and Flow API messaging increase flexibility and control over flow execution and orchestration. * Accessibility enhancements and better user interface support improve usability for all users, including those with disabilities.
