Citrix Workspace app for Windows 2508 - Preview

Note:

  • If.NET isn’t installed on the system or a version less than 8.0.16 is installed on the system, Citrix Workspace app installs .NET version 8.0.16.

  • If you install any supported higher version of .NET, Citrix Workspace app is compatible with the highest available .NET version (up to 8.x).

What’s new

The following is a list of features that are available in Citrix Workspace™ app 2508 for Windows:

Enhanced self-service troubleshooting and user experience

Starting with Citrix Workspace app for Windows 2508, users now receive intelligent, contextual error recommendations that:

  • Provide specific, actionable guidance based on the precise error condition
  • Enable self-service resolution for common connection issues
  • Reduce dependency on administrator intervention
  • Improve the overall connectivity experience, particularly in persistent VDA environments

These enhancements help address session connectivity issues that can be difficult to diagnose and resolve, empowering users to troubleshoot launch failures independently.

Extends long-term support to Windows 11 IoT enterprise LTSC

Citrix Workspace app for Windows now supports Windows 11 IoT Enterprise Long-Term Servicing Channel (LTSC), offering vital stability and reliability for these devices. This crucial enhancement supports fixed-function, special-purpose devices, ensuring a 10-year long-term support lifecycle, providing essential and lasting stability. This support particularly benefits industries like banking, quick-service restaurants, healthcare, hospitality, manufacturing, and retail, requiring consistent equipment operation.

Automated Endpoint Analysis client installation

The Endpoint Analysis client for Windows now automatically installs with Citrix Workspace app, providing significantly easier deployment than previous GACS-only automatic installation options. This auto-installation greatly aids deployment for customers using BYOD and unmanaged devices, streamlining processes for administrators and boosting overall efficiency.

Note:

Starting with Endpoint Analysis client version 25.8.1.2, support for 32-bit systems has been discontinued.

Service continuity enabled without self-service mode

Disabling self-service mode removes the user interface, allowing users to launch applications and desktops exclusively through shortcuts.

Service continuity is now supported even when self-service mode is disabled in Citrix Workspace app for Windows.

Enhanced storebrowse session handling

Starting with this release, storebrowse’ session handling is improved with the following enhancements, optimizing user experience and critical resource management within high-availability environments to boost efficiency:

  • Storebrowse intelligently ignores existing sessions when launching virtual applications - This option prevents reconnects to sessions actively being torn down by the system now, improving stability. This ensures seamless, error-free access to critical business applications, especially during client updates, simplifying management by reducing complex configuration needs. To enable intelligent session handling, administrators must add the -I true parameter to existing storebrowse commands. This parameter integrates seamlessly with all existing launch types while maintaining current syntax structure.

    Command example:

    Quick Launch:

    Previous syntax:

     .\storebrowse.exe -U {Username} -P {Password} –D {Domain} -q {Launch_URL_of_published_ apps and desktops} <https://cwa-ddc2c.cwa.com/Citrix/Store/resources/v2/Q29udHJvbGxlci5DYWxjdWxhdG9yLVRTVkRBMTk-/launch/ica> < https://cwa-ddc2c.cwa.com/citrix/store/discovery>
     <!--NeedCopy-->
    

    Enhanced syntax with intelligent session handling:

     .\storebrowse.exe -U {Username} -P {Password} –D {Domain} -I true -q {Launch_URL_of_published_ apps and desktops} https://cwa-ddc2c.cwa.com/Citrix/Store/resources/v2/Q29udHJvbGxlci5DYWxjdWxhdG9yLVRTVkRBMTk-/launch/ica> < https://cwa-ddc2c.cwa.com/citrix/store/discovery>
     <!--NeedCopy-->
    
  • Storebrowse API support for returning session lists - This option provides valuable visibility into active user sessions, enabling more contextualized and efficient session launches. This improved visibility decreases user-impacting errors and delays during application access, ensuring a smoother, more reliable experience for all users.

Support for GACS claimed URLs for the US Gov region

Starting with version 2508, Citrix Workspace app supports discovery of Global App Config Service (GACS) claimed URLs for the US Gov region alongside commercial cloud deployments.

You can select the region from which Citrix Workspace app retrieves discovery endpoints using the GACS Discovery Region policy setting.

  1. Open the Citrix Workspace app Group Policy Object administrative template by running gpedit.msc.

Modular Browser Content Redirection

Starting with the Citrix Workspace app 2508 for Windows, the Browser Content Redirection (BCR) component is now managed as a modular component, separate from the main Citrix Workspace app installer.

This new modular and evergreen model allows the Browser Content Redirection component to be updated independently and uninstalled independently. This feature provides the following key benefits:

  • Enhanced security: The BCR Chromium Embedded Framework component can receive security patches and updates as soon as they are available, without waiting for a full Citrix Workspace app release.
  • Simplified Management: Customers no longer need to update entire Citrix Workspace app to receive the latest Browser content redirection features.
  • Accelerated Innovation: Faster deployment of new BCR features, enhancements, and bug fixes is now possible, delivering continuous value to customers

To ensure a consistent user experience, the Modular BCR component is installed by default in Citrix Workspace app.

Installation and management:

When you install or upgrade to Citrix Workspace app 2508 or later, the installer includes the latest BCR component and installs it by default. No additional action is needed to install the BCR component.

For environments that do not use Browser Content Redirection, you can prevent its installation using the ADDLOCAL command-line switch during setup. When specifying ADDLOCAL components, do not include “BCR Client” to prevent BCR installation. For more information, see the Install and Uninstall section.

Manual installation and uninstallation:

  • To install: If you exclude the BCR component during initial setup, you can install it anytime by downloading the standalone installer from the Citrix Downloads page.
  • To uninstall: The BCR component can be uninstalled separately from Citrix Workspace app anytime by uninstalling the Citrix Browser Content Redirection Plug-in from the Windows Settings > Apps >Installed Apps section.

Automatic updates:

Once the modular and evergreen BCR component is installed, it keeps itself up-to-date automatically. The component periodically checks for new versions and silently installs them in the background. This automatic update ensures you always have the latest features and security updates without manual upgrades.

Note:

Once you upgrade Citrix Workspace app to 2508 or later Current Releases, the BCR experience is consistent across releases. There is only one BCR package regardless of Current Release or LTSR.

Upgrading to Citrix Workspace app 2508:

The transition from the older, integrated BCR is designed to be seamless. When you upgrade an existing Citrix Workspace app version to 2508 or later, the installer automatically replaces the old component with the new modular version. Users continue to have Browser Content Redirection functionality without any change to their experience.

Zoom 64-bit plug-in management support

Zoom has announced that Version 6.2.10 is the last version to support a 32-bit plugin. For more information, see Zoom documentation.

Starting from 2508 version onwards, Citrix Workspace app installs the Zoom plug-in management based on the endpoint architecture. If endpoint OS is 64-bit, then Citrix Workspace app installs 64-bit plugin management and keep it updated through auto-update service.

uberAgent add-on support for managed devices in Citrix Workspace app

The uberAgent add-on delivers advanced monitoring and diagnostics for Citrix Workspace app, providing detailed insights into user experience and application performance. This integration is available exclusively on managed devices, streamlining deployment and reducing administrative overhead.

Command-line Installation:

  • Use /InstallUberAgent to install or upgrade the uberAgent plugin.
  • Use /InstallUberAgent /SkipUberAgentUpgrade to install the plugin without upgrading it if uberAgent is already present. This option is ideal for VDAs or devices where uberAgent deployment is managed separately from Citrix Workspace app.

Enhanced background blur persistence for webcam

Starting with version 2508, the background blur setting persists between sessions and reconnects. Citrix Workspace app remembers your preference automatically. You can enable the background blur feature by navigating to Preferences > Connections and select Enable background blur.

Background blur

Your background blur setting remains active across all future sessions until you change it.

Enhanced keyboard layout settings notification

Starting with this release, the keyboard layout settings UI displays a warning that informs you that a session relaunch is required for changes to take effect.

Keyboard layout

License telemetry upload using Citrix Workspace app

With this release, you can upload license telemetry data to Citrix Analytics Service through client connections when the license server cannot reach Citrix Analytics service directly.

When your license server loses connectivity to Citrix Analytics service, the feature automatically routes telemetry data through the Virtual Desktop Agent (VDA) and client connection. This ensures continuous license reporting regardless of Customer Experience Improvement Program (CEIP) settings.

Benefits:

  • Maintains uninterrupted license telemetry reporting
  • Helps preserve compliance requirements
  • Provides consistent usage analytics for your Citrix environment
  • Works independently of CEIP configuration

Enable noise suppression

Starting with the 2508 version, Citrix Workspace app now offers improved audio redirection with enhanced noise suppression. This feature reduces background noise, ensuring clearer and more accurate speech, improving the overall communication experience.

Note:

This feature is disabled by default.

To enable this feature, do the following:

  1. Navigate to the Preferences > Connections section. The Noise Suppression screen appears.

    Noise supperession

  2. Select one of the following levels:

    • None: This level is the default setting and doesn’t use or affect resource consumption.
    • Low: Noise reduction is minimal and uses the least resource consumption.
    • High: Noise reduction is applied at maximum intensity with the best performance and uses higher resource consumption than the Low setting.
  3. Click OK. The selected configuration is applied.

Note:

Changes apply only to the current session and reset once the session ends.

Browser Profile Sharing in Browser Content Redirection (Technical Preview)

Browser Content Redirection (BCR) now offers a streamlined user experience with the new Profile Sharing feature, enabling VDA-side authentication and cookie sharing. This enhancement eliminates redundant logins, boosting productivity by maintaining authentication and cookie persistence across BCR sessions, even after the BCR window is closed. This seamless experience further enhances security by ensuring authentication originates from the VDA, not the client.

Example:

  • Previous experience: Previously, opening an authenticated page within BCR required users to re-enter their credentials each time, breaking SSO persistence. SSO was only maintained while the BCR window remained open. Closing and reopening the window forced users to repeat the login process.
  • New experience: With Profile Sharing, users are no longer prompted for credentials. SSO is seamlessly preserved from the VDA browser, providing a significantly improved and uninterrupted experience.

For information on versions from which Tech Preview is available, see Citrix Virtual Apps and Desktops documentation.

HDX graphics superresolution upscaling (Preview)

Starting with the Citrix Workspace app for Windows 2508 version, the HDX graphics superresolution upscaling feature enhances session performance and significantly reduces bandwidth consumption.

HDX Graphics Superresolution upscaling seamlessly downscales video regions on the Virtual Desktop Agent (VDA) and utilizes a compatible endpoint Graphics Processing Unit (GPU) to upscale them back to their original resolution without noticeable quality degradation or performance impact.

For more information, see HDX graphics superresolution upscaling (Preview).
