    Key Features

    • Enhanced Try-Catch Component (Patch 7): Allows selective inclusion of actions within Try-Catch blocks to refine error handling and improve workflow stability.
    • Role-Based Access Control (Patch 4): Only users with the snrpafdn.rpaadmin role can create, update, or delete Robot License Distribution records, enhancing security governance.
    • Long-Term Support (LTS) Models: Stable AI models within Now LLM Service provide extended stability suitable for regulated industries, supporting governance and compliance.
    • New AI Model Providers (Patch 1): Integration with Google Gemini and Anthropic Claude on AWS expands AI options for RPA bot generation alongside Now LLM Service and Azure OpenAI.
    • Python Connector: Enables execution of custom Python scripts within automation workflows in RPA Desktop Design Studio, complementing existing VB.NET, C#, and JavaScript connectors.
    • Smart Card Authentication: Supports secure unattended robot logins using physical smart cards, facilitating automation on machines requiring smart card credentials.
    • Enhanced Access Controls: Restricts RPA bot generation skill access to users with RPA developer or admin roles, aligning with AI security directives.

    Upgrade and Activation

    RPA Hub is available for installation via the ServiceNow Store. Customers upgrading from San Diego or Tokyo releases to Zurich must set the system property glide.rollback.blacklist.TableParentChange.change to false prior to upgrade to avoid table extension issues. Upgrading requires updating Microsoft Software Installers (MSIs) for RPA components to Zurich versions to ensure compatibility.

    Post-upgrade, bot process definitions transition to a new configuration structure requiring manual update if the system property is not set correctly.

    Hardware and Software Requirements

    • Unattended Robot: Minimum 2-core 1.8 GHz CPU, 4 GB RAM, 50 GB free disk; recommended 4-core 2.4 GHz CPU, 8 GB RAM, 100 GB disk; supports Windows 10 and Server 2016/2019/2022; .NET Framework 4.7.1+ required; DPI scaling disabled.
    • High-Density Robots: Hardware specs scale with the number of concurrent runtimes; VMs must be persistent and continuously running.
    • Attended Robot: Minimum Intel 1 vCPU, 4 GB RAM, 20 GB disk; recommended 4 vCPU, 8 GB RAM, 50 GB disk; Windows 10 or Server 2016/2019 supported; .NET Framework 4.7.1+ required; DPI scaling disabled.
    • RPA Desktop Design Studio: Minimum Intel Core i5, 4 GB RAM, 20 GB disk; recommended Core i7, 8 GB RAM, 50 GB disk; Windows 10 or Server 2016/2019 supported; .NET Framework 4.7.1+; 1920x1080 resolution monitor; DPI scaling disabled.

    See Robotic Process Automation (RPA) Hub for more information.

    Important:
    RPA Hub is available in the ServiceNow Store. For details, see the "Activation information" section of these release notes.

    Important information for upgrading RPA Hub to Zurich

    Upgrade any of these currently installed Microsoft Software Installers (MSIs) by downloading the RPA applications:
    • RPA Desktop Design Studio
    • Attended Robot
    • Unattended Robot
    • Unattended Robot Login Agent
    For more information, see Download the RPA applications from RPA Hub.

    The following upgrade information is applicable only when you’re upgrading from San Diego or Tokyo to Zurich.

    Based on the number of records in the application file table, you may experience a delay while upgrading the RPA Hub applications from Tokyo or earlier releases to Zurich.

    Before upgrading RPA Hub to Zurich, you must set the value of the glide.rollback.blacklist.TableParentChange.change system property to false. If this property doesn't exist in the System Property [sys_properties] table, add the property and set its value to false. For more information on how to add a property, see Add a system property.

    After you upgrade to Zurich, the bot process definitions change to the new structure, which is the bot process configuration.

    Although the bot process configuration doesn't replace the bot process completely, most fields are moved from the bot process to the bot process configuration. If you upgrade to Zurich without updating the system property value, the tables don’t extend the Application File [sys_metadata] table. To update the table changes manually, see the Restructuring RPA Hub tables to sys_metadata in Utah and beyond release [KB1223629] article in the Now Support Knowledge Base.

    New in the Zurich release

    Zurich Patch 7
    Try catch component enhancement
    You can now precisely control the scope of Try-Catch blocks by selecting which actions (components) to include within exception handling and which to manage outside it. This enhancement provides better control over error handling logic and improves workflow reliability.
    Zurich Patch 4
    Role changed for creating, updating, and deleting the Robot License Distribution records
    Role for Create, Update, and Delete ACLs in the Robot License Distribution table is changed from admin to sn_rpa_fdn.rpa_admin.
    Long term stable models
    Long term stable (LTS) models are part of Now LLM Service and provide longer model stability windows for regulated industries. These models can integrate with tools to provide governance, monitoring, and compliance controls.
    Zurich Patch 1
    New third-party AI model provider options available for all AI applications
    Google Gemini and AWS Claude are available for RPA bot generation skill in addition to Now LLM Service and Azure OpenAI.
    Python connector
    Execute custom Python scripts or files as part of an automation workflow in the RPA Desktop Design Studio.
    The connector comprises two methods:
    • Execute: Runs Python scripts set up in the configuration window.
    • InvokeScript: Runs Python script on local computers and gets the output.
    Ensure to install the Scripting plugin from the Plugins Manager as a prerequisite. Along with Python, VB.NET, C#, and Javascript connectors are available with this plugin.
    Smart Card authentication
    Use a physical smart card instead of a username and password for logging into a Windows machine.

    You can run unattended automations on the machines that use smart cards for authentication. While configuring a robot credential, you can store the smart card username and password to allow the unattended robot to log in to machines that use smart card.

    Enhanced ACLs for security measures
    Enhanced access controls for RPA bot generation skill for Now Assist for RPA Hub in compliance with AI security directives.

    Access to RPA bot generation skill is now restricted to users with the RPA developer or RPA admin role. These roles contain the RPA Hub Admin user role (sn_nowassist_admin.user).
