Show full answer Show less ## New Features * **Guarded Script Evaluator Enhancements:** Introduced in Yokohama Patch 13, this feature enhances instance security by restricting JavaScript features and APIs in sandboxed scripts from untrusted sources. Incompatible scripts from guest users are now rejected by default, while scripts from authenticated users undergo phased enforcement, allowing detection and review before rejection. Administrators can manage incompatible scripts through an Incompatible Guarded Scripts list for rewriting or exemption. * **Dynamic Attributes in Dynamic Categories:** You can now add individual or grouped dynamic attributes to dynamic categories and establish dependencies between dynamic attribute store fields and attributes or attribute lists. * **Remote Table Data Editing:** Enables insertion, updating, and deletion of data in external data sources via remote tables on an instance. Script definitions controlling these operations are customizable to fit your integration needs. ## Changes * **Access Control Lists (ACLs) Updates:** ACLs for several Transaction Management and Session Management tables have been enhanced to improve security by combining Deny and Allow rules and introducing a security attribute required for ACL role assignment. This applies to tables such as syslog, sysaudit, and sysusersession, among others. * **TinyMCE HTML Editor Plugin:** The Accessibility Checker (a11ychecker) plugin is now available, helping identify WCAG and Section 508 accessibility violations with an auto-repair feature. Configuration options include adjusting WCAG levels and HTML versions. * **Configurable Workspace Support:** Additional field types such as Documentationfield, Domainpath, HTMLScript, and several numeric and selection fields are now supported in configurable workspaces. * **REST API Access Policy Enhancements:** You can now specify which tables a Table REST API access policy applies to directly within the API Access Policy form. * **FX Currency Field Type Update:** ISO 4217 three-digit numeric currency codes are now used with FX Currency field types, improving currency data handling. * **Session Language Sorting:** Sorting of string values in columns can be configured to respect the user's session language or default to English. * **Columnstore Index Type:** A new columnstore index type is available with RaptorDB Professional, optimizing data storage and retrieval performance. * **Help Content Access:** Help content is streamlined on the system events and job scheduling dashboard to provide context-specific assistance in each tab. ## Removals and Deprecations No features or functionalities were removed or deprecated between Xanadu and Yokohama for the ServiceNow AI Platform core features. ## Activation and Requirements * The ServiceNow AI Platform core features are active by default upon upgrade to Yokohama. * No additional requirements, browser constraints, accessibility, or localization changes were introduced between these releases. ## Practical Implications for ServiceNow Customers Upgrading to Yokohama brings enhanced security and manageability for scripts, improved data integration capabilities with remote table editing, and accessibility improvements via TinyMCE plugins. The ACL enhancements strengthen data protection on critical tables. The new indexing options and configurable workspace field types improve performance and customization. Customers should review and manage incompatible sandbox scripts proactively using the new guarded script features and adjust ACL role assignments to comply with the updated security attributes. Configuring the accessibility checker in TinyMCE can help maintain compliance with accessibility standards. Finally, take advantage of the new REST API policy configurations and currency code improvements to streamline integrations.
