    Deprecations and Removals

    Activation and Installation

    • CSM Configurable Workspace is available through activation of the Customer Service plugin (com.sncustomerservice).

    Browser and Accessibility Considerations

    • ServiceNow workspaces, including Agent experience for CSM, do not support mobile devices, Internet Explorer, or the legacy Microsoft Edge. Supported browsers include Microsoft Edge Chromium and others listed in ServiceNow’s Browser support documentation.
    • Xanadu introduced template updates supporting reflow for accessibility, enabling page zoom up to 400% without loss of functionality, aiding users with low vision. This reflow can be disabled via system property if needed.

    Why This Matters

    Upgrading to Yokohama with the outlined features and improvements enables agents to interact more efficiently through enhanced chat and voice capabilities, better customer context visibility, and streamlined UI components. The deprecation of older workspaces directs customers towards a more modern, supported experience. Following activation and upgrade tasks ensures that Customer Service Management operates smoothly and that agents benefit from the latest productivity and usability enhancements.
