Key Features

  • Help Content Access: Users can now directly access relevant help content within each tab of the system events and job scheduling dashboards, improving user guidance and support.
  • Remote Table Data Editing: Administrators can insert, update, and delete data in external data sources via remote tables when editing is enabled, with customizable script definitions to control these operations.
  • Guarded Script Enhancements: The guarded script evaluator restricts untrusted JavaScript features in sandbox environments to enhance security. Incompatible scripts from guest users are rejected by default, with phased enforcement for authenticated users and tools to manage incompatible scripts.
  • Dynamic Attribute Management: New capabilities allow adding individual or grouped dynamic attributes to categories and establishing dependencies between dynamic attributes.
  • Access Control List (ACL) Updates: Transaction and Session Management tables have updated ACLs introducing a security attribute requirement to bolster security through combined Deny and Allow rules.
  • TinyMCE HTML Editor Plugin: The Accessibility Checker plugin is now available, identifying WCAG and Section 508 compliance issues with auto-repair options, configurable via TinyMCE settings.
  • Configurable Workspace Field Support: Additional field types such as Documentationfield, HTMLScript, Radio, and others are now supported within configurable workspaces.
  • REST API Access Policy Enhancements: REST API access policies can now specify the exact tables they apply to, improving access control precision.
  • Currency Field Enhancements: FX Currency field types support three-digit ISO 4217 numeric currency codes, enabling standardized currency handling.
  • Language-Sensitive Sorting: Column sorting can now be configured to respect the user's session language rather than defaulting to English.
  • Columnstore Index Type: A new columnstore index type is introduced for optimized data storage and retrieval, available with RaptorDB Professional.

Key Outcomes

  • Improved Security: Enhanced sandbox script evaluation and updated ACLs provide stronger protection for your instance and data.
  • Greater Data Control: Editing capabilities for remote tables and refined REST API policies give administrators more precise data management tools.
  • Better Accessibility and Usability: Inline help access, accessibility checking in the HTML editor, and support for additional workspace fields improve user experience and compliance.
  • Optimized Performance: Advanced indexing options help optimize data handling for faster and more efficient operations.
  • Standardized Currency Handling: Use of ISO currency codes ensures consistency in financial data processing.

New in the Yokohama release

Enhance instance security for sandbox scripts with guarded script
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.
Add dynamic attributes to a dynamic category
Add individual attributes or a group of attributes to a dynamic category.
Reference a dynamic attribute or a list of dynamic attributes
Build a dependency between a dynamic attribute store field and either a dynamic attribute or a list of dynamic attributes.
Edit data in remote tables on an instance
Insert, update, and delete data in an external data source from a remote table on an instance when you enable editing for the table. Customize the script definitions that enable you to insert, update, or delete data from a remote table.

Changed in this release

Updated Access Control Lists (ACLs) for Transaction tables and Session Management tables
The ACLs for a number of Transaction Management tables and Session Management tables have been updated to enhance security using a combination of Deny and Allow ACLs. All new ACLs have a security attribute. You must have the security attribute to add to the role list of an ACL. For more information, see Configure an ACL rule, Deny-Unless ACL, and .
The updated Transaction Management tables include:
  • syslog
  • syslog_ajax
  • syslog_email
  • syslog_transaction

  • sys_audit
  • sys_security_acl
  • sys_user_auth
  • sys_user_session
Configuring plugins for the TinyMCE HTML editor
The Accessibility Checker (a11ychecker) plugin is now available in the TinyMCE HTML editor. The plugin identifies WCAG and Section 508 accessibility violations and provides an auto-repair feature where applicable. To configure the plugin, see Change the TinyMCE HTML editor plugins. Additional configurations to the accessibility rules, like changing the WCAG level and HTML versions can also be done via TinyMCEconfigscript script.
Field types supported in a configurable workspace
The following field types are now supported for use in a configurable workspace:
  • Documentation_field
  • Domain_path
  • HTML_Script
  • Long
  • Longint
  • multi_small
  • Order index
