It highlights new features, changes, and important upgrade considerations to ensure smooth transitions and enhanced automation capabilities within the ServiceNow AI Platform®. Show full answer Show less Key upgrade advice includes reviewing pre- and post-upgrade tasks, restoring the "save as you go" functionality if previously disabled, and understanding new security enhancements for read-only fields that improve instance security while maintaining flexibility. ## Key Features * **Now Assist Integration:** Create and edit flows during app generation, call Now Assist skills from actions, and generate flows or subflows from images using AI assistance. * **Conversational Compatibility:** Check and configure actions and subflows for conversational compatibility, generate skill and input descriptions via generative AI, and set default or hidden input values to streamline user interactions. * **Automation Recommendations:** Receive automation type suggestions (playbook, flow, subflow, action, data stream) based on simple inputs to optimize workflow creation. * **Enhanced Debugging and Reusability:** Debug flows and subflows with breakpoints and step-through features, save reusable flow triggers, and pause flows awaiting specific messages or email replies. * **External Event Sources and Triggers:** Create domain-separated external event sources and reusable scheduled triggers to integrate external systems and align automation with business calendars, holidays, and operating hours. * **AI Agent Actions:** Use flow data to run AI agents within flows, configuring expected outputs for dynamic automation. * **Flow and Subflow Management:** Automatically save work, view and compare flow histories side-by-side, analyze flow executions for errors with suggested fixes, and display subflow stages within parent flows for better visibility. * **User Experience Improvements:** Adoption of the Coral theme as default, updated UI buttons for debugger and conversational settings, and natural language descriptions of data used in flows improve usability and clarity. ## Important Upgrade Information * Restore the "save as you go" feature if disabled during earlier releases (Washington DC). * New granular read-only field protections enhance security without breaking compatibility; consult KB2718122 for technical guidance. * The role `now.assist.creator` is no longer required to use generative AI features with Now Assist. * Workflow Studio is active by default and receives continuous updates via the ServiceNow Store. ## Changes and Enhancements * Improved error messaging in conversational actions and subflows to provide more specific feedback. * Ability to filter reference fields in inputs to limit records for better control. * New Event Sources menu simplifies management of external event sources. * Flow recommendations now appear in the flow diagramming view to assist in next-step decisions. ## Removals and Deprecations No features or functionalities related to Flows, subflows, and actions were removed in the upgrade from Yokohama through Australia. However, note the deprecation of the `now.assist.creator` role for generative AI usage. ## Practical Outcomes for ServiceNow Customers * **Increased Automation Efficiency:** Enhanced AI-driven automation capabilities allow for quicker flow creation, debugging, and conversational integration. * **Improved Security:** Granular control over read-only fields strengthens instance security while maintaining workflow flexibility. * **Better User Experience:** Updated UI elements and themes, along with natural language descriptions, facilitate easier flow management and comprehension. * **Seamless Integration:** External event sources and scheduled triggers enable tighter integration with external systems and business calendars. * **Enhanced Testing and Troubleshooting:** Tools for flow execution analysis, conversation-enabled action testing, and error identification improve reliability before production deployment. Consolidated page of all release notes for Flows, subflows, and actions from Yokohama to Australia. ## 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. Read this summary of the new features, changes, and updated information for your product from Yokohama to Australia. Tip: If there were no updates for a release notes section in a certain family release, we included a short note for your reference. For example, if a product did not have any updates in Tokyo, the row says "No updates for this release." ## Important information for upgrading Flows, subflows, and actions to Australia Before you upgrade to Australia, review these pre- and post-upgrade tasks and complete the tasks as needed. {#dfrn3-flowssubflowsandactions-summary__entry__2} | Release | Release notes | |-|-| | Yokohama | No updates for this release. | | Zurich | No updates for this release. | | Australia | Upgrade information : 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](https://www.servicenow.com/docs/access?context=restore-save-as-you-go-functionality&family=australia&ft:locale=en-US). The Australia release introduces enhanced protections for read‑only fields across the ServiceNow AI Platform®. These changes include a new "read_only_option" field with granular control levels, including "strict_read_only" and "client_script_modifiable". The changes occur in the back end and maintain backward‑compatible behavior. This update helps strengthen your instance security while preserving the flexibility you need. Refer to [KB2718122](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2718122) for additional technical details on how to identify affected fields and adjust their settings. For more information about granular read-only security options, see [Configuring read-only security options](https://www.servicenow.com/docs/access?context=read-only-option&family=australia&ft:locale=en-US). | [ ] ## New features Between your current release family and Australia, new features were introduced for Flows, subflows, and actions. {#dfrn3-flowssubflowsandactions-summary__entry__10} | Release | Release notes | |-|-| | Yokohama | [Add and edit flows in Now Assist for app generation](https://www.servicenow.com/docs/access?context=sns-app-gen-add-flow&family=yokohama&ft:locale=en-US) : Create a flow when creating an application in Now Assist for app generation.
