Release	Release notes
Yokohama	Yokohama Patch 3 Add and edit flows in Now Assist for app generation Create a flow when creating an application in Now Assist for app generation. Enhance an existing application by adding a flow. Call a Now Assist skill from an action Run a published Now Assist skill from an action. Configure the Now Assist skill inputs and skill outputs from the step inputs and step outputs. Check for conversational compatible actions Run a compatibility check on new or all actions to determine if they are conversational compatible. Review the inputs of an action to determine if their data types are compatible. Check for conversational compatible subflows Run a compatibility check on new or all subflows to determine if they are conversation compatible. Review the inputs of a subflow to determine if their data types are compatible. Create a flow or subflow from an image Create a flow or a subflow from an image by using Now Assist. Capture the detailed process in an image and attach the image to Workflow Studio. Now Assist generates a preview of the flow that you can modify and regenerate. Display text descriptions of the data used by actions and flow logic See a natural language description of the data each component of a flow uses. Understand what data flow triggers, actions, and flow logic blocks use without having to open their configuration details. Generate skill and input descriptions for conversational actions Configure conversational settings for conversational actions by generating skill and input descriptions with generative AI. Generate skill and input descriptions for conversational subflows Configure conversational settings for conversational subflows by generating skill and input descriptions with generative AI. Set default values for action inputs Set a default value for a conversational action input. Hide action inputs that have a default value if you don't want users to change the input value in a conversation. Set default values for subflow inputs Set a default value for a conversational subflow input. Hide subflow inputs that have a default value if you don't want users to change the input value in a conversation. Summarize a flow or subflow Summarize what a flow or subflow does by using generative AI. Support additional input data types for conversational actions Support conversational actions that have Dynamic Choice and Array of Objects input types. Support additional input data types for conversational subflows Support conversational subflows that have Dynamic Choice and Array of Objects input types. Create the recommended automation type Answer a few questions about your automation and Workflow Studio displays recommendations on whether you should create a playbook, flow, subflow, action, or a data stream. Yokohama Patch 1 Configure conversational settings View the subflows and actions that are conversational compatible. Configure conversational settings to make a subflow or action available to conversational interfaces. Yokohama Early Availability Debug flows and subflows Debug flows and subflows from a dedicated Workflow Studio tab. Set breakpoints and step through a paused flow to review configuration and runtime values. Save a flow trigger for reuse in other flows Save a set of trigger definitions as a reusable trigger. Enable flow authors to select the saved trigger from some or all application flows. Specify whether flow authors can see the trigger details or add conditions to the trigger. Use the Flow API to send a message to a paused flow Send a specific message and payload response to a flow that is paused and waiting for a message. Wait for a specific message from the Flow API Pause a flow until it receives a specific message from the flow API. Specify the string message that resumes running the flow, and optionally provide a time out value to resume the flow if no message is received after a specific amount of time.
Zurich	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 Show subflow stages as part of the execution details of a parent flow. Save flows, subflows, and actions automatically Save flows, subflows, and actions automatically as you work on them. Support Now LLM Long Term Stable models (LTS) with Flow generation Support the Now LLM Long Term Stable models (LTS) for Flow generation. Support Now LLM Long Term Stable models (LTS) with Flow summarization Support the Now LLM Long Term Stable models (LTS) for Flow summarization. Use an AI agent action Use flow data to run an AI agent and configure the expected agent output for use later in the flow. Use your preferred LLM to generate descriptions for subflow or action skill, input, and output Leverage generative AI to generate descriptions for the subflow or action skill, inputs, and outputs. You can configure a default LLM to generate the descriptions. View flow history View and manage the history of a flow. See past configurations of a flow to copy, restore, or remove them. View subflow history View and manage the history of a subflow. See past configurations of a subflow to copy, restore, or remove them.
