Show full answer Show less ## Key Features * **OT CMDB Search and Device Import (Yokohama and Zurich):** Use the OT CMDB search function to quickly locate OT configuration items (CIs) and device information. Additionally, streamline your OT device inventory management by uploading, validating, and importing spreadsheets through the "Import OT device spreadsheet into OT CMDB" agentic workflow. * **Now LLM Service Deprecation (Zurich):** The Now LLM Service is no longer the default language model provider for new or inactive AI assets; a third-party LLM is selected by default, though manual selection of the Now LLM Service remains available. * **Now Assist Usage Measurement Updates (Yokohama Patch 5 and Zurich):** Usage reporting has shifted from a 365-day look-back model to a 365-day burn-down model resetting on the contract anniversary, providing more accurate consumption tracking for AI capabilities. * **Default Activation of Now Assist Skills and Agentic Workflows:** New installations automatically enable designated generative AI skills, agents, and workflows for appropriate user roles. For existing customers upgrading, any AI assets never configured and turned on before are now activated by default, while previously deactivated assets remain off. * **Role Masking for Security:** Agentic workflows and AI agents use role masking to control user access. When restricting access to specific roles, customers must configure security controls and data access settings accordingly to ensure proper permissions. * **Coral Theme Introduction (Zurich):** The new default theme for portals, web, and mobile experiences offers a modern, brand-neutral design with an optional dark theme to improve readability and reduce eye strain. * **ServiceNow Otto Conversational AI Platform (Zurich):** ServiceNow Otto is the integrated conversational AI platform powering agentic capabilities and multimodal interactions across channels, enabling autonomous orchestration of cross-system workflows. ## Upgrade and Activation Guidance * Before upgrading to Zurich, review and complete the documented pre- and post-upgrade tasks to ensure a smooth transition. * Operational Technology (OT) Manager Foundation is an AI Platform feature available by activating the Operational Technology Manager (com.snotfoundation) application. * The product is available through the ServiceNow Store for installation and activation. ## Changes and Considerations * No features or functionality were removed or deprecated between Xanadu and Zurich releases for OT Manager Foundation. * Some AI-related features and usage measurements have evolved, requiring customers to review their configurations and usage reporting expectations. * Ensure that roles and permissions are appropriately configured for newly enabled AI skills, agentic workflows, and role masking security to maintain compliance and secure access. * New Coral theme and dark mode options enhance the user experience but may require updates to branding or user preferences. ## Accessibility and Localization The Zurich release introduces a dark theme option to improve accessibility by reducing eye strain and enhancing readability for web and mobile users. No additional localization changes or specific browser requirements were noted for OT Manager Foundation across these releases. ## Practical Benefits for ServiceNow Customers * Improved efficiency in managing OT device data through enhanced search and import workflows. * More accurate and aligned AI usage measurement supports better cost and capacity planning. * Out-of-the-box activation of AI skills accelerates adoption and productivity gains. * Role masking ensures security and compliance in agentic workflows and AI access. * Modernized user interface with Coral theme and dark mode improves user satisfaction and accessibility.

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).
