[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&version=yokohama&pubname=yokohama-operational-technology&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. ## Changed in this release {#now-assist-for-otm-rn__now-assist-for-otm-rn-changed-features} **[Yokohama Patch 11](https://servicenow-prod.fluidtopics.net/o~Ty6nl6ETxZAE_DIVoJJw "The Yokohama Patch 11 release contains important problem fixes.")** [Changes to Now Assist usage measurement](https://www.servicenow.com/docs/access?context=monitoring-now-assist-usage&version=yokohama&pubname=yokohama-platform-administration&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&version=yokohama&pubname=yokohama-intelligent-experiences&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. {#now-assist-for-otm-rn__ul_rdx_4xn_nhc} [Role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&version=yokohama&pubname=yokohama-intelligent-experiences&ft:locale=en-US) : [Role masking](https://www.servicenow.com/docs/access?context=aia-role-masking&version=yokohama&pubname=yokohama-intelligent-experiences&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&version=yokohama&pubname=yokohama-intelligent-experiences&ft:locale=en-US). ## Activation information {#now-assist-for-otm-rn__now-assist-for-otm-rn-activation} 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).
