Show full answer Show less ## Important Upgrade Information * **Pre- and Post-Upgrade Tasks:** Review and complete necessary tasks before upgrading to Brazil, especially regarding new protections for read-only fields. * **Read-Only Field Protections:** Brazil and Australia releases introduce a new "readonlyoption" field with granular control (e.g., "strictreadonly" and "clientscriptmodifiable") to enhance instance security while maintaining backward compatibility. * **Save-as-You-Go Feature:** Australia release restored save-as-you-go functionality that may have been disabled in Washington DC upgrades; instructions provided to reactivate. ## New Features * **Now Assist Integration:** Create and edit flows during app generation, call Now Assist skills from actions, and generate flows or subflows from images for simplified automation design. * **Conversational AI Enhancements:** Added compatibility checks for conversational actions and subflows, AI-generated skill/input/output descriptions, default input values with optional hiding, support for new input data types (Dynamic Choice, Array of Objects), and testing capabilities for conversational components. * **Flow Development and Management:** Enhanced Workflow Studio with flow debugging, breakpoint setting, flow input modification during debugging, and automatic saving of flows, subflows, and actions. * **Trigger Improvements:** Support for reusable saved triggers, domain-separated external triggers, scheduled triggers, and business calendar-based triggers that align automation with business schedules. * **Flow Execution and Troubleshooting:** Flow execution analysis tools, flow history comparisons, a flow troubleshooting agent for diagnosing errors conversationally, and the ability to publish system events on flow errors or interruptions. * **AI Agent Actions:** Use flow data to run AI agents and configure outputs for downstream steps in flows. * **External Event Sources:** Create and manage external event sources to trigger flows based on events outside the ServiceNow AI Platform®. * **User Experience Updates:** Coral theme adoption, enhanced UI elements for conversational settings, and new menus for event source management. ## Changes * Improved visibility of data usage in flows via natural language descriptions. * UI and navigation enhancements such as updated buttons for flow debugger and conversational settings access. * Introduction of the Coral default theme with dark mode support for portals and mobile. ## Deprecations and Removals * The `now.assist.creator` role is no longer required for generative AI features with Now Assist starting from Australia release. * No major removals of flows, subflows, or actions features between Yokohama and Brazil releases. ## Activation and Requirements * **Workflow Studio:** Active by default in both Australia and Brazil releases as part of the ServiceNow AI Platform®. Customers should update Workflow Studio via the ServiceNow Store to access the latest features. * No additional browser or localization requirements introduced between Yokohama and Brazil for Flows, subflows, and actions. ## Practical Benefits for ServiceNow Customers * Leverage enhanced automation tools and AI-driven flow creation to accelerate app development and process automation. * Improve security posture with granular read-only field controls without sacrificing flexibility. * Use conversational AI features to build more interactive, user-friendly automation interfaces. * Debug and troubleshoot flows more effectively with integrated tools and conversational agents. * Reuse triggers and events to streamline flow design and maintenance. * Align automation with business schedules and external systems through new trigger and event source capabilities. By upgrading to Brazil, customers gain access to improved automation, AI-driven design and troubleshooting, stronger security controls, and better management tools for flows, subflows, and actions, enabling more efficient and resilient automation workflows. Consolidated page of all release notes for Flows, subflows, and actions from Yokohama to Brazil. ## How to use this page To help you prepare for your upgrade, we have combined the cross-family Flows, subflows, and actions release notes onto one page.
