Show full answer Show less ## Important Upgrade Information * The **dynamic schema application framework** has been revised in Zurich. Existing dynamic schema implementations from Xanadu or Yokohama releases will be automatically migrated during upgrade. Customers should review the Dynamic Schema Zurich Migration Guide for details. * **Guarded script security** enhancements continue from Yokohama to Zurich. This feature restricts JavaScript APIs and features in sandboxed scripts to improve instance security by rejecting incompatible scripts from guest users by default and phasing enforcement for authenticated users. ## New Features * **Feature Preview Program:** Centralized access to discover, activate, and test pre-release capabilities on your instance, with notifications and feedback options. * **Automatic request definitions for scripted REST APIs:** Generate request headers, query parameters, and request schemas from sample API requests, improving API design and documentation. * **Schema-based API requests and responses:** Define request and response structures in schemas that are included in OpenAPI exports for REST APIs. * **Experimentation framework:** Enables early access to new ServiceNow feature variants for eligible customers, with options to opt out or disable experiments. * **Inbound API usage monitoring:** Track API usage rates for OAuth-registered applications and user accounts via a dashboard. * **Hierarchical queries in condition builders:** Simplify complex queries using hierarchical relationships within tables. * **Dynamic namespaces:** Define categories and attributes once and reuse them across multiple tables and fields, improving schema management. * **Audit Management Console:** Provides simplified audit data management with automated retention and deletion options. * **AI indicator in forms:** Visual cues identify fields updated with AI-generated content, improving transparency in configurable workspace and Core UI. * **Coral theme:** New default theme for portals, web, and mobile experiences with brand-neutral illustrations and optional dark theme for better accessibility and user comfort. * **ECMAScript 2021 (ES12) support:** Enables modern JavaScript features such as Promises and Async/Await in scripting. * **Stream multipart REST API responses:** Improves performance by streaming multipart/mixed responses instead of buffering them. * **Expanded field type support and layout options:** Additional field types supported in configurable workspaces, including vertical radio button layouts and enhanced dictionary attributes. * **New TinyMCE plugins:** Image editing and help plugins improve content editing and accessibility compliance. * **Enhanced scheduled job configurations:** New run types and advanced options allow more flexible scheduling and execution control. * **Export to Google Sheets:** Users can export lists directly to Google Sheets from the Export menu. ## Changes and Enhancements * **Updated ACLs for Transaction and Session Management tables:** Enhanced security using combined Deny and Allow ACLs with new security attributes. * **Accessibility improvements:** Accessibility Checker plugin added to TinyMCE editor to identify and auto-repair WCAG and Section 508 violations. * **Sorting configuration:** Ability to configure string sorting according to user session language. * **Removed dynamic groups:** Replaced by dynamic attributes in dynamic categories to streamline administration and improve user experience. ## Deprecations * **Application Insights:** No longer deployed or supported starting with Zurich. Customers are encouraged to use the Overview of Instance Observer for system performance monitoring. * **glide.script.use.sandbox system property:** Removed as the script sandbox is now enabled by default. ## Activation and Additional Notes * ServiceNow AI Platform core features remain **active by default** in both Yokohama and Zurich releases. * No additional browser requirements or localization changes were introduced in Zurich. * The new Coral theme includes a **dark theme option** to improve readability and reduce eye strain in web and mobile experiences. ## Practical Benefits for ServiceNow Customers * Improved **security** for sandboxed scripts reduces risk from untrusted code. * **Dynamic schema improvements** and namespaces simplify schema management and reuse. * **Feature Preview Program** allows early evaluation of upcoming features to plan adoption. * **Enhanced API tooling** automates request/ Consolidated page of all release notes for ServiceNow AI Platform core feature from Yokohama to Zurich. ## How to use this page To help you prepare for your upgrade, we have combined the cross-family ServiceNow AI Platform core feature release notes onto one page.

If you implemented dynamic schema in Xanadu or Yokohama, the application is automatically migrated to a new framework as part of the upgrade to the Zurich release. For details on the migration, see the [Dynamic Schema Zurich Migration Guide \[KB2146133\]](https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB2146133) article in the Now Support Knowledge Base. | [ ] ## New features Between your current release family and Zurich, new features were introduced for ServiceNow AI Platform core feature. {#dfrn3-servicenowaiplatformcorefeature-summary__entry__8} | Release | Release notes | |-|-| | Yokohama | [Enhance instance security for sandbox scripts with guarded script](https://www.servicenow.com/docs/access?context=guarded-script&family=yokohama&ft:locale=en-US) : The guarded script evaluator restricts the JavaScript features and APIs available to untrusted, client-generated scripts running in the script sandbox environment. Beginning with the Yokohama Patch 13 release, incompatible scripts sent to the server by guest users are rejected on all instances by default. Scripts sent by authenticated users are evaluated using a phased approach to enforcement that varies by the type of instance to provide time to detect and review incompatible scripts before rejecting them. Scripts that use unsupported features are recorded in the Incompatible Guarded Scripts list, where you can rewrite them or create exemptions for scripts that can't be rewritten.
