New Features

OT CMDB Search Function: Introduced in Yokohama Patch 10 and continued in Zurich, this feature allows you to quickly search for OT configuration items (CIs) and OT device information within the OT CMDB tables, improving device record findability.
Import OT Device Spreadsheet Workflow: Also introduced in Yokohama Patch 10 and supported in Zurich, this agentic workflow automates the process of uploading, validating, and importing OT device inventory spreadsheets into ServiceNow, simplifying data management tasks for your OT assets.

Changes

Now Assist Usage Measurement: Starting with Yokohama Patch 5 and refined through Zurich Patch 5, usage measurement transitioned from a 365-day look-back model to a 365-day burn-down model with resets at contract anniversaries. This change affects how consumption is tracked and reported.
Default Activation of Skills and Workflows: Since Yokohama Patch 11 and continuing in Zurich Patch 4, certain Now Assist skills, agents, and agentic workflows are enabled by default for appropriate roles (such as ITIL roles on incident or change forms). For new customers, these are activated upon installation; for existing customers upgrading, unconfigured components are automatically enabled, while previously turned-off components remain inactive. Additional role configuration may be required to fully utilize these features.
Role Masking: This feature was removed in Zurich Patch 4.

Removals and Deprecations

No features or functionalities were removed or deprecated between Yokohama and Zurich releases.
