Show full answer Show less ## New Features * **OT CMDB Search Function:** Enables users to quickly locate OT configuration items (CIs) and device information within the OT CMDB tables, improving efficiency in asset and configuration management. * **Import OT Device Spreadsheet Workflow:** Introduces an agentic workflow to upload, validate, and import OT device inventory spreadsheets directly into the OT CMDB, simplifying and automating device data management within ServiceNow. ## Changes * **Now Assist Usage Measurement:** Starting with Yokohama Patch 5, usage measurement transitions from a 365-day look-back model to a 365-day burn-down model, resetting usage at the contract anniversary date. This affects how usage is tracked and reported. * **Default Activation of Now Assist Skills and Workflows:** From Yokohama Patch 11 onward, certain Now Assist skills, agents, and agentic workflows are automatically enabled for users with relevant roles (e.g., ITIL). Existing customers upgrading will have unconfigured skills automatically turned on, while previously configured and deactivated skills remain off. * **Role Masking for Agentic Workflows:** Provides enhanced security by limiting the roles and privileges assigned to agentic workflows during execution. Customers must configure security controls and data access settings to include the necessary roles to ensure proper operation. ## Activation Information Operational Technology (OT) Manager Foundation is an AI Platform feature available with the activation of **Operational Technology Manager (com.snotfoundation)**. It can be installed through ServiceNow and is also available via the ServiceNow Store. Proper activation is required to leverage the full capabilities of the OT Manager Foundation. ## Additional Notes * There were no removed or deprecated features between Xanadu and Yokohama releases. * No changes to browser requirements, accessibility, localization, or additional requirements were noted for Yokohama. * Upgrade preparatory and post-upgrade tasks should be reviewed to ensure a smooth transition. ## Practical Benefits for ServiceNow Customers * Faster and more accurate searching of OT configuration data enhances operational efficiency. * Streamlined import workflows reduce manual data entry errors and save time managing OT device inventories. * Improved usage tracking and default skill activation simplify management of Now Assist capabilities. * Enhanced security controls via role masking ensure that agentic workflows operate within defined privilege boundaries.

[Upload, validate, and import your OT device inventory spreadsheet using the Import OT device spreadsheet into OT CMDB agentic workflow](https://www.servicenow.com/docs/access?context=upload-import-validate-ot-device-inventory-spreadsheet&family=yokohama&ft:locale=en-US) : Use the Import OT device spreadsheet into OT CMDB agentic workflow to begin the process for uploading, validating, and importing your OT device inventory into ServiceNow. | [ ] ## Changes Between your current release family and Yokohama, some changes were made to existing Operational Technology (OT) Manager Foundation features. {#dfrn3-operationaltechnologyotmanagerfoundation-summary__entry__14} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | [Changes to Now Assist usage measurement](https://www.servicenow.com/docs/access?context=monitoring-now-assist-usage&family=yokohama&ft:locale=en-US) : Starting with Yokohama Patch 5, Now Assist 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: 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). | [ ] ## Removed Between your current release family and Yokohama, some Operational Technology (OT) Manager Foundation features or functionality were removed. {#dfrn3-operationaltechnologyotmanagerfoundation-summary__entry__20} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | No updates for this release. | [ ] ## Deprecations Between your current release family and Yokohama, some Operational Technology (OT) Manager Foundation features or functionality were deprecated. {#dfrn3-operationaltechnologyotmanagerfoundation-summary__entry__26} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | No updates for this release. | [ ] ## Activation information Review information on how to activate Operational Technology (OT) Manager Foundation. {#dfrn3-operationaltechnologyotmanagerfoundation-summary__entry__32} | Release | Release notes | |-|-| | Xanadu | No updates for this release. | | Yokohama | Activation information : Operational Technology (OT) Manager Foundation is a ServiceNow AI Platform feature that is available with activation of the Operational Technology Manager (com.sn_ot_foundation).
