Show full answer Show less ## New features * **OT CMDB Search Function:** Enables users to quickly find OT configuration items (CIs) and OT device information within OT CMDB tables. * **Import OT Device Spreadsheet Workflow:** Introduces an agentic workflow to upload, validate, and import OT device inventory spreadsheets into ServiceNow, streamlining device data management. * **Now LLM Service Deprecation (Zurich):** The Now LLM Service is no longer the default large language model provider for new or inactive AI assets. A third-party LLM is now selected by default, though Now LLM Service remains available for manual selection. * **Coral Theme (Zurich):** A fresh, brand-neutral Coral theme is now the default for new portal, web, and mobile experiences using Next Experience or Core UI, including an optional dark mode to improve readability and reduce eye strain. ## Changes * **Now Assist Usage Measurement:** Transition from a 365-day look-back model to a 365-day burn-down model with usage resetting at the contract anniversary date, improving AI usage tracking accuracy. * **Default Activation of AI Skills and Workflows:** Some generative AI skills, agents, and agentic workflows are automatically enabled for appropriate user roles, simplifying initial setup. This applies to new installations and certain upgrades. * **Role Masking for Agentic Workflows:** Security is enhanced by restricting access to agentic workflows and AI agents based on specific user roles. Customers must configure security controls accordingly to manage role-based access. * **Renaming:** "Now Assist for OTM" is renamed to "OT Manager Foundation" to reflect the product identity more clearly. ## Removed and Deprecated Features No features or functionalities were removed or deprecated between Yokohama and Zurich releases. ## Activation and Additional Requirements * Operational Technology (OT) Manager Foundation is an AI Platform feature activated via the Operational Technology Manager (com.snotfoundation) plugin. * The product is available for activation through the ServiceNow Store. * No new additional or browser-specific requirements were introduced. ## Accessibility and Localization * The new Coral theme includes an accessible dark mode option to support various user needs. * No specific localization updates were noted. ## Important Considerations for ServiceNow Customers * Review pre- and post-upgrade tasks to prepare for the Zurich upgrade. * Leverage the OT CMDB search function and import workflow to improve operational efficiency in managing OT devices. * Understand the impact of Now LLM Service deprecation and configure AI model selections as needed. * Ensure proper role configurations are applied to agentic workflows and AI agents for secure access control. * Take advantage of the updated Coral theme and its dark mode to enhance user experience across web and mobile platforms.

For more information, refer to [KB KB2704710: Now Assist Usage - Overview \& New Measurement Logic](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2704710). [Some Now Assist skills, agents, and agentic workflows are turned on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&family=yokohama&ft:locale=en-US) : The skills are automatically available to appropriate role users for the application, such as ITIL roles on incident forms or change forms. This change simply activates the skill and does not touch the roles that may be needed to use the skill. The new default behavior works as follows: * New customers: When you install a Now Assist product, designated skills and agentic workflows are turned on automatically. * Existing customers who are upgrading (starting with Yokohama Patch 11): Any previously unconfigured skill, agent, or agentic workflow is turned on automatically (the AI asset was never configured and turned on, then turned off again). Previously configured skills and agentic workflows that were turned on, then off, remain inactive. [Role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&family=yokohama&ft:locale=en-US) : [Role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&family=yokohama&ft:locale=en-US) enables users to limit the roles and privileges of agentic workflows during tool execution. Agentic workflows and their AI agents that get installed with Now Assist applications are assigned pre-defined roles. If you select Users with specific roles for user access, you must configure the security controls to include these roles. Data access settings must also include these roles. For the instructions to change the security controls, see [Define security controls for an agentic workflow](https://www.servicenow.com/docs/access?context=define-sec-controls-aw&family=yokohama&ft:locale=en-US). | | Zurich | [Now Assist for OTM was renamed to OT Manager Foundation](https://www.servicenow.com/docs/access?context=now-assist-for-otm-landing&family=zurich&ft:locale=en-US) : Now Assist for Operational Technology Manager (OTM) was renamed to Operational Technology (OT) Manager Foundation. [Changes to Now Assist usage measurement](https://www.servicenow.com/docs/access?context=monitoring-now-assist-usage&family=zurich&ft:locale=en-US) : Starting with Australia Early Access, AI usage measurement is transitioning from a 365-day look-back model to a 365-day burn-down model, with usage resetting at the contract anniversary date. For more information, refer to [KB KB2704710: AI Usage - Overview \& New Measurement Logic](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2704710). [Some generative AI skills, AI agents, and agentic workflows are turned on by default](https://www.servicenow.com/docs/access?context=now-assist-skills-on-by-default&family=zurich&ft:locale=en-US) : The skills are automatically available to appropriate role users for the application, such as ITIL roles on incident forms or change forms.

Previously configured skills and agentic workflows that were turned on, then off, remain inactive. [Role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&family=zurich&ft:locale=en-US) : Agentic workflows and their AI agents use [role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&family=zurich&ft:locale=en-US) to determine which users can access them. Ones installed with your applications have specific roles that come included with the application. If you select Users with specific roles for user access, you must configure the security controls to include these roles. For the instructions to change the security controls, see [Define security controls for an agentic workflow](https://www.servicenow.com/docs/access?context=define-sec-controls-aw&family=zurich&ft:locale=en-US).
