About this release

What’s new in 2103.1

Enhancement to keyboard layout configuration

The keyboard layout configuration now includes a Don’t sync option. The option is available for both the Group Policy Object (GPO) policy and the GUI configurations.

When you select the Don’t sync option, the server keyboard layout is used in the session and the client keyboard layout is not synced to the server keyboard layout.

For more information, see Keyboard layout and language bar.

Option to disable storing of authentication tokens

Authentication tokens are encrypted and stored on the local disk so that you don’t need to reenter your credentials when your system or session restarts.

With this release, Citrix Workspace app introduces an option to disable the storing of authentication tokens on the local disk. For enhanced security, we now provide a Group Policy Object (GPO) policy to configure the authentication token storage.

Note:

This configuration is applicable only in cloud deployments.

For more information, see Authentication tokens.

Microsoft Teams enhancements

  • The VP9 video codec is now disabled by default.
  • Enhancement to echo cancellation, auto gain control, noise suppression configurations: If Microsoft Teams configures these options, Citrix-redirected Teams honors the values as configured. Otherwise, these options are set to True by default.
  • DirectWShow is now the default renderer.

    To change the default renderer, do the following:

    • Launch the Registry editor.
    • Navigate to the following key location: HKEY_CURRENT_USER\SOFTWARE\Citrix\HDXMediaStream.
    • Update the following value: "UseDirectShowRendererAsPrimary"=dword:00000000

      Other possible values:

      • 0: Media Foundation
      • 1: DirectShow (Default)
    • Relaunch the Citrix Workspace app.

What’s new in 2102

Proxy authentication support

Previously, on client machines configured for proxy authentication, if the proxy credentials were not stored in Windows Credential Manager, you could not authenticate to Citrix Workspace app.

Now, on client machines configured for proxy authentication, if the proxy credentials are not stored in Windows Credential Manager, an authentication prompt appears, asking you to enter the proxy credentials. Citrix Workspace app then saves the proxy server credentials in Windows Credential Manager. This results in a seamless login experience because you do not need to manually save your credentials in Windows Credential Manager before accessing Citrix Workspace app.

Microsoft Teams enhancements

  • Improved video rendering.
  • Performance and reliability improvements.

What’s new in 2012.1

This release addresses issues that help to improve overall performance and stability.

What’s new in 2012

Support for Italian language

Log collection

Log collection simplifies the process of collecting logs for Citrix Workspace app. The logs help Citrix to troubleshoot, and, in cases of complicated issues, facilitate support.

You can now collect logs using the GUI.

For more information, see Log collection.

Support for the domain pass-through authentication on Citrix Workspace

This release introduces support for the domain pass-through authentication on Citrix Workspace, along with the existing support for StoreFront.

Silent authentication for Citrix Workspace

Citrix Workspace app introduces a Group Policy Object (GPO) policy to enable silent authentication for Citrix Workspace. This policy enables Citrix Workspace app to log in to Citrix Workspace automatically at system startup. Use this policy only when domain pass-through (single sign-on) is configured for Citrix Workspace on domain-joined devices.

For more information, see Silent Authentication.

Enhancement to app protection configuration

Previously, the authentication manager and the Self-Service plug-in dialogs were protected by default.

This release introduces a Group Policy Object (GPO) policy that lets you configure the anti-keylogging and anti-screen-capturing functionalities separately for both the authentication manager and Self-Service plug-in interfaces.

Note:

This GPO policy is not applicable for ICA and SaaS sessions. ICA and SaaS sessions continue to be controlled using the Delivery Controller and Citrix Gateway Service.

For more information, see Enhancement to app protection configuration.

Microsoft Teams enhancements

  • Peers can now see the presenter’s mouse pointer in a screen sharing session.
  • The WebRTC media engine now honors the proxy server configured on the client device.

What’s new in 2009.6

Support for FIDO2 authentication

FIDO2 authentication lets users take advantage of the local endpoint FIDO2 components. Users can now authenticate using FIDO2 security keys or integrated biometrics. Devices must have Trusted Platform Module (TPM) 2.0 and Windows Hello. For more information, see FIDO2: WebAuthn & CTAP.

Microsoft Teams enhancements

  • Microsoft Teams now displays previously used peripheral devices in the Preferred devices list.
  • The WebRTC media engine accurately determines the maximum encoding resolution possible on an endpoint. The WebRTC media engine estimates multiple times a day and not only on first launch.
  • The Citrix Workspace app installer is now packaged with the Microsoft Teams ringtones.
  • Echo cancellation improvements - Reduced echo level when a peer has a speaker or microphone that generates an echo.
  • Screen sharing improvements - Now when you do screensharing, only the Desktop Viewer screen is captured in native bitmap format. Previously, client local windows that overlaid on top of the Desktop Viewer window were blacked out.

What’s new in 2009

This release addresses issues that help to improve overall performance and stability.

What’s new in 2008

Group Policy Object (GPO) administrative template configuration for keyboard layout and language bar

For more information, see Keyboard layout and language bar.

CryptoKit update

Citrix Workspace app now supports Version 14.2.1 of the CryptoKit.

Language support

Citrix Workspace app for Windows is now available in the Portuguese (Brazil) language.

Authentication enhancement

To provide a seamless experience, the authentication dialog now appears inside Citrix Workspace app. The Store details appear on the logon screen. Authentication tokens are encrypted and stored so that you don’t need to reenter the credentials in case of a system reboot or session restart.

Note:

This authentication enhancement is applicable only in cloud deployments.

Enhancement to app protection

Previously, when you are trying to take a screenshot of a protected window, the entire screen, including the non-protected apps in the background, are blacked out.

Now, when you are taking a screenshot using a snipping tool, only the protected window is blacked out. You can take a screenshot of the area outside the protected window.

However, if you are using the PrtScr key to capture a screenshot on a Windows 10 device, you must minimize the protected window.

Additionally, this release addresses issues to improve the app protection feature.

Enhancement to Browser Content Redirection

  • Cookies are now persistent across the sessions: When you exit and relaunch a browser, you are not prompted to reenter your credentials.
  • Browsers now honor the local system language.

What’s new in 2006.1

Support for Dual Tone Multi Frequency (DTMF) with Microsoft Teams

Support for Dual-Tone Multifrequency (DTMF) signaling interaction with telephony systems (for example, PSTN) and conference calls in Microsoft Teams. This feature is enabled by default.

Enhancement to Microsoft Teams screen sharing

With this release, the contents shared using Microsoft Teams are limited to the contents of the Desktop Viewer window. Areas outside the Desktop Viewer window are cropped, and the client’s local apps that overlap the Desktop Viewer appear blacked out.

For more information, see Screen sharing.

Update to Citrix Analytics Service

Citrix Workspace app is instrumented to securely transmit data to Citrix Analytics Service from ICA sessions that you launch from a browser.

For more information on how Citrix Analytics uses this information, see, Self-Service for Performance and Self-service search for Virtual Apps and Desktops.

What’s new in 2002

App protection

Disclaimer

App protection policies work by filtering access to required functions of the underlying operating system (specific API calls required to capture screens or keyboard presses). This means that app protection policies provide protection even against custom and purpose-built hacker tools. However, as operating systems evolve, new ways of capturing screens and logging keys emerge. While we continue to identify and address them, we can’t guarantee full protection in specific configurations and deployments.

App protection is an add-on feature that provides enhanced security when using Citrix Virtual Apps and Desktops. The feature restricts the ability of clients to be compromised by keylogging and screen capturing malware. App protection prevents exfiltration of confidential information such as user credentials and sensitive information that is displayed on the screen. The feature prevents users and attackers from taking screenshots and from using keyloggers to glean and exploit sensitive information.

Note:

Citrix recommends that you only use the native Citrix Workspace app to launch a protected session.

App protection is configured between StoreFront and the Controller using the Controller. For information about configuring app protection on the Controller, see App protection in Citrix Virtual Apps and Desktops documentation. This configuration is then applied to Citrix Workspace app by including the app protection component using any of the following methods:

  • GUI
  • Command-line interface

You can include the app protection component both during the Citrix Workspace app installation or on-demand installation.

Note:

  • This feature is supported only on Microsoft Windows Desktop operating systems such as Windows 10, Windows 8.1, and Windows 7.
  • This feature is not supported over Remote Desktop Protocol (RDP).

For information about configuring app protection in Citrix Workspace app, see App protection.

Installer enhancement

In earlier releases, if an administrator tried to install Citrix Workspace app on a system that has a user-installed instance of the app, the installation was blocked.

With this release, the administrators can now override the user-installed instance of Citrix Workspace app and continue with the installation successfully.

Enhancement to Citrix Workspace Updates

In earlier releases, if Citrix Workspace app is installed by an administrator, a non-administrator might not update it.

With this release, a non-administrator can update Citrix Workspace app on an admin-installed instance. You can do that by right-clicking the Citrix Workspace app icon in the notification area and selecting Check for Updates.

Note:

The Check for Updates option is now available on both the user-installed and the admin-installed instances of Citrix Workspace app.

Support for outbound proxy

SmartControl allows administrators to define granular policies to configure and enforce user environment attributes for Citrix Virtual Apps and Desktops using Citrix Gateway. For instance, you might want to prohibit users from mapping drives to their remote desktops. This can be achieved using the SmartControl feature on Citrix Gateway.

However, the scenario changes when Citrix Workspace app and Citrix Gateway belong to separate enterprise accounts. In such scenarios, the client domain cannot apply the SmartControl feature because the gateway does not exist on the client domain. Instead, you can use the Outbound ICA Proxy. Outbound ICA Proxy lets you use the SmartControl feature even when Citrix Workspace app and Citrix Gateway are deployed in different organizations.

Citrix Workspace app supports session launches using the Citrix ADC LAN proxy. Either a single, static proxy can be configured or the proxy server can be selected at runtime using the outbound proxy plug-in.

You can configure outbound proxies using the following methods:

  • Static proxy: Proxy server is configured by providing a proxy host name and port number.
  • Dynamic proxy: A single proxy server can be selected among one or more proxy servers using the proxy plug-in DLL.

You can configure the outbound proxy using the Group Policy Object administrative template and the Registry editor.

For more information about outbound proxy, see Outbound ICA Proxy support in the Citrix Gateway documentation.

For more information about configuring the outbound proxy, see Outbound proxy.

Citrix Embedded Browser binaries

You can now exclude the Citrix Embedded Browser binaries so as to not use this feature.

This release introduces a command-line switch to exclude the Citrix Embedded Browser binaries. Run the /InstallEmbeddedBrowser=N switch from the Citrix Workspace app install location to discontinue the embedded browser feature.

You can exclude the Citrix Embedded Browser binaries only in the following cases:

  • Fresh install
  • Upgrade from a version that does not include the Citrix Embedded Browser binaries.

If your version of Citrix Workspace app includes the Citrix Embedded Browser binaries and you are upgrading to Version 2002, the embedded browser binaries are automatically updated during the upgrade.

Enhancement to desktop sharing with Microsoft Teams

When you share your workspace using Microsoft Teams, Citrix Workspace app displays a red border that surrounds the area of the monitor that is currently being shared. You can share only the Desktop Viewer window, or any local window overlaid on top of it. When you minimize the Desktop Viewer window, screen sharing is paused.

Endpoint encoder performance estimator on Microsoft Teams

When the HdxTeams.exe process (the WebRTC media engine embedded in Citrix Workspace app that handles Microsoft Teams redirection) is launched, it estimates the best encoding resolution that the endpoint’s CPU can sustain without overloading. Possible values are 240p, 360p, 720p and 1080p.

The performance estimation process (also called webrtcapi.EndpointPerformance) runs when HdxTeams.exe initializes. The macroblock code determines the best resolution that can be achieved with a particular endpoint. The highest possible resolution is then included during the codec negotiation between the peers, or between the peer and the conference server.

For information on configuring endpoint encoder, see Encoder performance estimator.

For information, see Optimization for Microsoft Teams in Citrix Virtual Apps and Desktops documentation.

Enhancement to Citrix Analytics Service

With this release, Citrix Workspace app is instrumented to securely transmit the public IP address of the most recent network hop to Citrix Analytics Service. This data is collected per session launch. It helps Citrix Analytics Service to analyze whether poor performance issues are tied to specific geographic areas.

By default, the IP address logs are sent to Citrix Analytics Service. However, you can disable this option on the Citrix Workspace app using the Registry editor.

To disable IP address log transmissions, navigate to the following registry path and set the SendPublicIPAddress key to Off.

  • On 64-bit Windows machines, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle.
  • On 32-bit Windows machines, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Dazzle.

Note:

  • IP address transmissions are best-case efforts. Although Citrix Workspace app transmits every IP address that it is launched on, some of the addresses might not be accurate.
  • In closed customer environments, where the endpoints are operating within an intranet, ensure that the URL https://locus.analytics.cloud.com/api/locateip is whitelisted on the endpoint.

For more information on how Performance Analytics uses this information, see Self-Service for Performance.

The auto-enroll feature is in Technical Preview. Citrix recommends using technical preview features only in test environments.

Citrix Workspace app now allows Windows 10 devices to automatically enroll in Endpoint Management.

Note:

  • This feature is supported only on Windows 10 devices.
  • This feature is applicable only on cloud deployments.

What’s new in 1909

New installer switch

  • You are upgrading from an unsupported version of Citrix Workspace app.
  • The installation or upgrade is unsuccessful.

Note:

/forceinstall switch is the replacement for /rcu switch.

For more information, see Common parameters in the Install section.

Fixed issues

Fixed issues in 2103.1

Logon/Authentication:

  • Even after you enable the keep me signed in and don’t ask again for 60 days policies, Microsoft Azure Multi-Factor Authentication might still prompt for authentication.

    Note:

    We recommend that users exit their stores rather than log off from their stores. If users log off from stores using webview authentication, they might be prompted for authentication again because Internet Explorer cookies are cleared in such scenarios. By default, the fix is enabled (cookies are stored). You can disable the fix by using the GPO option. If you disable the fix, the cookies are not stored and are cleared during logoff.

    [CVADHELP-14814]

  • On Azure Active Directory (AD) joined devices, when Citrix Workspace app attempts to access a store and then passes through endpoint logon credentials, users might not be authorized to log on. Also, there is no option to log on with a different user account. [CVADHELP-14844]

  • With the Vprefer option enabled in Citrix Workspace app, published applications might launch locally, but you might experience the following two issues:
    • The system environment is not expanded, For example, %computername% as a command-line parameter is not expanded at the local client to PC12345. System environment variables do not expand. For example, %computername% as a command-line parameter does not expand to PC12345 on the local client machine.
    • Command-line parameters are not passed back to the client. For example, when using selfservice’.exe -qlaunch IE11 http://www.citrix.com, the command-line parameter is passed as “Iexplore.exe %*” instead of being passed back to the client.
