• 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An earlier version of the save as you go feature was released and withdrawn from the Washington DC release.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.

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 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.

• 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

• 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.

• 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.

• 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.

• 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

• 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.

• 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.

Test a conversational subflow to verify it responds correctly to user inputs and performs the expected operations before deploying it in production.

• 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.
