About this release

What’s new in 2108

App protection

The app protection feature is now fully functional.

App protection requires that you install an add-on license on your License Server. A Citrix Virtual Desktops license must also be present. For information on Licensing, see the Configure section in the Citrix Virtual Apps and Desktops documentation.

The app protection feature supports apps and desktop sessions and is enabled by default. However, you must configure the feature in the AuthManConfig.xml file to enable it for authentication manager and Self-Service plug-in interfaces.

Starting with this release, you can launch protected resources from Citrix Workspace app while Mozilla Firefox is running.

For more information, see App protection.

Audio configuration enhancement

Previously, the default value of the VdcamVersion4Support attribute in the module.ini file was set to True. With this release, the default is set to False. As a result, only the default audio device with the name Citrix HDX Audio appears in the session. This enhancement aims to minimize the audio issues that occur when the attribute is set to True.

To enable this feature, do the following:

  1. Navigate to the \<ICAROOT\>/config/ folder and open the module.ini file.
  2. Go to the clientaudio section and add the following entry:

    VdcamVersion4Support=True

  3. Restart the session for the changes to take effect.

What’s new in 2106

Chromium Embedded Framework (CEF) for Browser Content Redirection

CEF-based browser content redirection is now fully functional. The feature is enabled by default.

Note:

This feature is not supported on the armhf platform.

For more information, see Enabling CEF-based BCR.

Battery status indicator

The battery status of the device now appears in the notification area of a Citrix Desktop session.

Note:

The battery status indicator does not appear for server VDAs.

For more information, see Battery status indicator.

Service continuity (Public Technical Preview)

Note:

This feature is in public technical preview for Citrix Workspace app.

Service continuity removes or minimizes the dependency on the availability of components that are involved in the connection process. Users can launch their virtual apps and desktops regardless of the health status of the cloud services.

For information on requirements that support service continuity on Citrix Workspace app, see System Requirements.

For information on installing service continuity with Citrix Workspace app, see Installing Service Continuity.

For more information, see the Service continuity section in the Citrix Workspace documentation.

App protection enhancement experimental feature

Previously, the authentication manager and the Self-Service plug-in dialogs were not protected even when app protection was installed and enabled.

Starting with this release, Citrix Workspace app introduces an option to let you configure the anti-keylogging and anti-screen-capturing functionalities separately for both the authentication manager and Self-Service plug-in interfaces.

For more information, see App protection.

User Interface enhancement

Previously, the settings menu was available from the Preferences option in the Desktop Viewer.

Starting with this release, the settings menu appears in-line with the Self-Service plug-in. The menu options are now improved to align with the look and feel of the native Citrix Workspace. This results in a seamless and a better user experience.

Settings menu

Note:

This enhancement is available by default in Citrix Workspace app Version 2106 in cloud deployments.

To switch to the native and old style appearance, do the following:

Navigate to $ICAROOT/config/AuthManConfig.xml and set the value of WebUISettings to false.

Microsoft Teams enhancement

You can now configure the preferred network interface for media traffic.

Navigate to \HKEY_CURRENT_USER\SOFTWARE\Citrix\HDXMediaStream and create a key by the name of NetworkPreference (REG_DWORD).

Select one of the following values as required:

  • 1- Ethernet
  • 2- Wi-Fi
  • 3- Cellular
  • 4- VPN
  • 5- Loopback
  • 6- Any

By default, the WebRTC media engine choses the best available route.

What’s new in 2104

App protection support on Red Hat Package Manager (RPM) experimental feature

App protection is now supported on the RPM version of Citrix Workspace app.

For more information, see App protection.

Enhancement to HDX Enlightened Data Transport Protocol (EDT)

In earlier releases, when HDXoverUDP is set to Preferred, data transport over EDT is used as primary with fallback to TCP.

With session reliability enabled, EDT, and TCP are attempted in parallel during the initial connection, session reliability reconnection, and auto client reconnect. This enhancement reduces connection time when EDT is preferred but the required underlying UDP transport is unavailable and TCP must be used.

By default, after fallback to TCP, adaptive transport continues to seek EDT every five minutes.

Microsoft Teams Optimization

With this release, the echo cancellation feature is disabled by default. We recommend that you not use your built-in speakers and microphone for calls. Use headphones instead.

This fix aims to address choppy audio issues noticed on thin clients.

Service continuity (Technical Preview)

Note:

This feature is in Technical Preview. Citrix recommends using this feature only in non-production environments. To sign up, use the following Podio form: Sign up: Service continuity Tech Preview for Citrix Workspace.

Service continuity removes or minimizes the dependency on the availability of components that are involved in the connection process. Users can launch their virtual apps and desktops regardless of the health status of the cloud services.

For more information, see Service continuity section in the Citrix Workspace documentation.

What’s new in 2103

Pinning multi-monitor screen layout

With this release, you can save the selection for multi-monitor screen layout. The layout is how a desktop session is displayed. Pinning helps to relaunch a session with the selected layout, resulting in an optimized user experience.

As a prerequisite, you must enable this feature in the AuthManConfig.xml file. Navigate to $ICAROOT/config/AuthManConfig.xml and add the following entries to enable the pinning screen layout feature:


     <key>ScreenPinEnabled</key>
     <value> true </value>
<!--NeedCopy-->

Only after adding the key above, you can see the Screen Layout option in the App indicator.

Note:

This feature is not available on the web launch of Citrix Workspace app.

For more information, see Pinning multi-monitor screen layout.

Increase in the number of supported virtual channels

In earlier versions of the client, sessions supported up to 32 virtual channels.

With this release, you can use up to 64 virtual channels in a session.

Microsoft Teams enhancements

The VP9 video codec is now disabled by default.

What’s new in 2101

Client drive mapping (CDM) enhancement

With this release, access to mapped drives comes with an additional security feature.

You can now select the access level for the mapped drive for every store in a session.

To stop the access level dialog from appearing every time, select the Do not ask me again option. The setting is applied on that particular store.

Otherwise, you can set the access levels every time a session is launched.

App protection support on Debian package experimental feature

App protection is now supported on the Debian version of Citrix Workspace app.

For silent installation of the app protection component, run the following command from the terminal before installing Citrix Workspace app:

export DEBIAN_FRONTEND="noninteractive"
sudo debconf-set-selections <<< "icaclient app_protection/install_app_protection select no"
sudo debconf-show icaclient
* app_protection/install_app_protection: no
sudo apt install -f ./icaclient_<version>._amd64.deb
<!--NeedCopy-->

Microsoft Teams enhancements

  • The Citrix Workspace app installer is now packaged with the Microsoft Teams ringtones.
  • Audio output switches automatically to newly plugged-in audio devices, and an appropriate audio volume is set.
  • HTTP proxy support for anonymous authentication.

What’s new in 2012

Client drive mapping (CDM) enhancement

Previously, your setting for file access through CDM was applied on all configured stores.

Starting with this release, Citrix Workspace app allows you to configure per-store CDM file access.

Note:

The file access setting isn’t’ persistent across sessions when using workspace for web. It defaults to the Ask me each time option.

For more information, see Client-drive mapping.

App protection experimental feature

Note:

  • This feature is supported only when Citrix Workspace app is installed by using the tarball package. Also, x64 and armhf are the only two supported packages.
  • This feature is supported only on on-premises deployments of Citrix Virtual Apps and Desktops.

App protection is an add-on feature that provides enhanced security when you use 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 displayed on the screen. The feature prevents users and attackers from taking screenshots and from using keyloggers to glean and exploit sensitive information.

For information about how to configure app protection on Citrix Virtual Apps and Desktops, see the App protection section in the Citrix Virtual Apps and Desktops documentation.

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

Authentication enhancement experimental feature

We now present the authentication dialog inside Citrix Workspace app and show store details on the logon screen for a better user experience. We encrypt and store authentication tokens so that you don’t need to reenter credentials when your system or session restarts.

Note:

  • This authentication enhancement is available only in cloud deployments.
  • This authentication enhancement is not available on ARMHF platform.

Prerequisite:

You must install the libsecret library.

This feature is disabled by default.

For more information, see Authenticate.

Audio configuration enhancement

Starting with this release, the default value of the VdcamVersion4Support attribute in the module.ini file is set to True.

For more information, see Audio.

What’s new in 2010

Enhanced audio redirection

Previously, only the default audio device was mapped in a session even when many devices were available on the machine. The mapped device commonly appeared as Citrix HDX Audio.

With this release, Citrix Workspace app for Linux displays all local audio devices that are available in a session. Instead of Citrix HDX Audio, they now appear with their respective device names. You can switch to any of the available devices dynamically in a session. Unlike in earlier releases, now you don’t need to select the default audio device before launching the session. Sessions update dynamically when you plug in or remove audio devices.

For more information, see Audio.

Additionally, this release addresses issues to improve the Multi-Stream ICA feature.

What’s new in 2009

Enhancement to logging

Previously, the debug.ini and module.ini files were used to configure logging.

As of Version 2009, you can configure logging using one of the following methods:

  • Command-line interface
  • GUI (GUI)

Also as of Version 2009, the debug.ini configuration file is removed from the Citrix Workspace app installer.

Logging captures the deployment details, configuration changes, and administrative activities of Citrix Workspace app to a logging database. A third-party developer can use the logging SDK, which is bundled as part of the Citrix Workspace app Platform Optimization SDK.

You can use the log information to:

  • Diagnose and troubleshoot issues that occur after any changes. The log provides a breadcrumb trail.
  • Assist change management and track configurations.
  • Report administration activities.

Note:

This logging mechanism is applicable only on Retail build.

For more information about logging, see Logging.

What’s new in 2006

Optimization for Microsoft Teams

Optimization for desktop-based Microsoft Teams using Citrix Virtual Apps and Desktops and Citrix Workspace app. Optimization for Microsoft Teams is similar to HDX RealTime Optimization for Microsoft Skype for Business. The difference is that, we bundle all the necessary components for Microsoft Teams optimization into the VDA and the Citrix Workspace app.

Citrix Workspace app for Linux supports audio, video, and screen sharing features with Microsoft Teams optimization.

Note:

Microsoft Teams optimization is supported only on x64 Linux distributions.

For information on how to enable logging, follow the steps mentioned under Logging for Microsoft Teams.

For information on system requirements, see Microsoft Teams Optimization.

For more information, see Optimization for Microsoft Teams and Microsoft Teams redirection.

Support for NetScaler App Experience(NSAP) virtual channel

Previously available as an experimental feature, the NetScaler App Experience (NSAP) virtual channel feature is now fully functional. The NSAP virtual channel helps in sourcing HDX Insight data, which improves scalability and performance. The NSAP virtual channel is enabled by default. To disable it, toggle the NSAP flag NSAP=Off in the module.ini file.

For more information, see HDX Insight in the Linux Virtual Delivery Agent documentation, and HDX Insight in the Citrix Application Delivery Management service documentation.

Update to Citrix Analytics Service

Citrix Workspace app is instrumented to 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.

TLS version update

Previously, the minimum TLS version supported was 1.0, and the maximum TLS version supported was 1.2.

Starting with this release, the minimum and maximum TLS version supported is 1.2. To configure a different value for MinimumTLS, see TLS.

CryptoKit update

CryptoKit Version 14.2 is integrated with the OpenSSL 1.1.1d version.

What’s new in 2004

Language support

Citrix Workspace app for Linux is now available in the Italian language.

Improved logon and enumeration performance

With this release, cloud user accounts notice shorter logon and app enumeration time.

Audio optimization for Microsoft Teams experimental feature

As an experimental feature, Citrix Workspace app provides audio optimization for Microsoft Teams running within a Citrix Virtual Desktop session.

Note:

Microsoft Teams audio optimization is supported only on the x64 Linux distributions.

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

Support for NetScaler App Experience (NSAP) virtual channel experimental feature

As an experimental feature, HDX Insight data is sourced from the NSAP virtual channel and sent uncompressed, which improves scalability and performance. The NSAP virtual channel is enabled by default. To disable it, toggle the NSAP flag NSAP=Off in the module.ini file.

For more information, see HDX Insight in the Linux Virtual Delivery Agent documentation, and HDX Insight in the Citrix Application Delivery Management service documentation.

What’s new in 1912

Transparent user interface enhancement

Version 1910 introduced the transparent user interface (TUI) feature, including the VDTUI flag. The feature helps the client system to receive the TUI packets sent by the server, and the client can access the UI-related components. However, with the flag set to Off, the “Starting <Application>” dialog rendered on top of other application windows, covering the login prompt.

Now, the VDTUI flag, located in the module.ini file, is set to On by default. As a result, the “Starting <Application>” dialog box no longer appears when you launch an app. Instead, a “Connecting <Application>” dialog appears with a progress bar. The dialog also displays progress of the app launch.

GStreamer 1.x support experimental feature

In earlier releases, GStreamer 0.10 was the default version supported for multimedia redirection. Starting with this release, you can configure GStreamer 1.x as the default version.

Limitations:

  • When you play a video, the forward and the backward option might not work as expected.
  • When you launch the Citrix Workspace app on ARMHF devices, GStreamer 1.x might not work as expected.

For more information, see Enabling GStreamer 1.x.

Chromium Embedded Framework (CEF) for Browser Content Redirection (BCR) experimental feature

The BCR feature redirects contents of a web browser to a client device. The feature creates a corresponding browser that embeds within the Citrix Workspace app.

Previously, BCR used a WebkitGTK+ based overlay to render the content. Starting with this release, BCR uses a CEF-based overlay for better user experience. It helps offload network usage, page processing, and graphics rendering to the endpoint.

For more information, see Enabling CEF-based BCR.

For information about BCR, see Browser content redirection in the Citrix Virtual Apps and Desktops documentation.

Notes:

  • The pacexec binary is removed from the x86 version of Citrix Workspace app.
  • Citrix Files might not be compatible with the Workspace with Intelligence feature.

What’s new in 1910

Language support

Citrix Workspace app for Linux is now available in the Brazilian Portuguese language.

App indicator icon

The app indicator starts when you launch Citrix Workspace app. It is an icon that is present in the notification area. With the introduction of the app indicator, the Citrix Workspace app for Linux logon performance is improved.

You can observe performance improvement when you:

  • First launch of Citrix Workspace app
  • Close and relaunch the app
  • Quit and relaunch the app

Note:

The libappindicator package is required for the app indicator to appear. Install the libappindicator package suitable for your Linux distribution from the web.

Transparent user interface

The Citrix ICA protocol uses Transparent User Interface Virtual Channel [TUI VC] protocol to transmit data between Citrix Virtual Apps and Desktops and host servers. The TUI protocol transmits user interface [UI] component messages for remote connections.

Previously, Citrix Workspace app for Linux did not support the TUI VC feature. As a result, the client system could not handle UI component data from the server efficiently. So, when attempted to launch an app, the “Starting <Application>” dialog rendered on top of other applications.

Now, Citrix Workspace app for Linux supports the TUI VC feature. This feature helps the client to receive the TUI packets sent by the server, and the client can access the UI-related components. This functionality helps you to control the display of the default overlay screen. You can toggle the VDTUI flag in the module.ini file: VDTUI - On/Off

For more information on Virtual Channels, see Citrix ICA virtual channels in the Citrix Virtual Apps and Desktops documentation.

Known issues in earlier releases

Known issues in 2106

  • In a desktop session, after a page is redirected using CEF-BCR, the keyboard focus might remain on the BCR overlay (for example, YouTube Search). The keyboard focus does not shift to other open apps. The issue occurs only on Self-Service plug-in and StoreBrowse launches. As a workaround, to shift the focus to other apps, click the session toolbar and select the Home button. [RFLNX-7704]
  • In a desktop session, after a page is redirected using CEF-BCR, the keyboard focus shifts to the current mouse location. The issue is caused by a third-party limitation on open source CEF. [RFLNX-7724]
  • When you try to click on the BCR overlay (for example, YouTube Search) with another application in foreground, the browser page does not appear on the foreground. [RFLNX-7730]
  • After a page is redirected using CEF-BCR, when you close the redirected webpage, a segfault is captured in the error logs. [RFLNX-7667]
  • During Microsoft Teams peer-to-peer audio calls, audio might not work for the first 15 seconds of the call. As a workaround, in the module.ini file, set the VdcamVersion4Support attribute to False. [HDX-29526]

Known issues in 2104

  • On VDA Version 1912 LTSR CU2, sessions might get disconnected. The issue occurs when you enable the Multistream policy on the Delivery Controller. As a workaround, upgrade the VDA to Version 2012 or later. [RFLNX-6960]

Known issues in 2103

  • During a video call or screen sharing, Microsoft Teams might turn unresponsive and the call might end abruptly. [CVADHELP-16918]

Known issues in 2101

  • When playing lengthy videos, the audio stops but the video continues to play seamlessly. The issue occurs when you set the VdcamVersion4Support to True. As a workaround, disable the multi-audio option by setting VdcamVersion4Support to False. [RFLNX-6472]
  • During a Microsoft Teams meeting, audio might be choppy when on mute. The issue occurs on thin-clients. [RFLNX-6537]
  • Sometimes, Citrix Workspace app might not be able to render the incoming videos in Microsoft Teams. [RFLNX-6662]
  • When you use the cefenablemediadevices flag with Microsoft Teams, the microphone does not work as intended. The issue occurs when using CEF-based BCR feature with Microsoft Teams. [RFLNX-6689]

Known issues in 2012

  • When a session gets terminated or disconnected abruptly, the HdxRtcEngine.exe process might exit unexpectedly. [RFLNX-5885]
  • When you attempt to enter text, the cursor appears white. The issue occurs in a double-hop scenario when connected from a Linux end-point machine. For a workaround, see the Knowledge Center article CTX272423 and CTX131504. [CVADHELP-16170]
  • When you establish HDX Optimization for a Microsoft Teams video call, the video might become unresponsive and the audio stops playing. The issue occurs when you disconnect or reconnect a headset during the call. [CVADHELP-16186]

Known issues in 2010

  • Unable to view files in the Files tab. The issue occurs in cloud deployments. [RFLNX-5596]
  • In Microsoft Teams, you must select the audio device manually. The audio device is not set as default automatically. [RFLNX-5652 ]
  • Attempts to use drop-down menu in a session with full-screen mode might fail. The issue occurs when browser content redirection is enabled. [CVADHELP-13884]
  • The TCP fallback option might not work even when HDXoverUDP is set to Preferred. The issue occurs when you connect using Citrix Gateway. [CVADHELP-15526]

Known issues in 2009

  • The Multi-Stream ICA feature might not work correctly. [RFLNX-4286]
  • When you are running a video call or sharing the screen in Microsoft Teams, the screen might flicker. [RFLNX-4778]
  • Attempts to switch between desktop sessions might fail. [CVADHELP-15229]

Known issues in 2006

  • Occasionally, the Meeting view doesn’t restore during multitasking in Microsoft Teams. The issue occurs when a local window overlays the remote window. As a result, the remote window does not receive the mouse events. As a workaround, on the minimized screen, hover over the digital clock and double-click on the caller’s name. [RFLNX-4937]
  • Sometimes, session reconnection fails. The issue occurs when you configure the Multi-Stream ICA (MSI) protocol with a single port over TCP with SD-WAN. [RFLNX-4782]

Known issues in 2004

  • Citrix Workspace app for Linux might fail to identify certain smart cards. As a result, attempts to launch a session with the card fail.
  • When you launch a session after enabling the Multi-Stream ICA (MSI) protocol in Workspace app and on SD-WAN, the session exits unexpectedly. The following error message appears:

    “The connection to VDA was lost…”

    The issue occurs because single-port MSI is not supported. [RFLNX-4219]

  • Session launch might fail on CentOS 8.x, Fedora 29, 30, and 31 distributions. For a workaround, see Knowledge Center article CTX270926. [RFLNX-3114]

Known issues in 1912

  • While using CEF-based BCR, the keyboard focus does not point back to the main window if you redirect a URL. As a workaround, create a browser tab and toggle to access the main tab. [RFLNX-3871]
  • While using CEF-based BCR, you might observe a notification that the webcontainer process has stopped. The issue occurs when you close the browser instance. [RFLNX-3872]
  • When you use the self-service user interface, the Preferences window options might not work as expected, and the Workspace application becomes temporarily unresponsive. The issue occurs on the Ubuntu 19.10 distribution. [RFLNX-3720]
  • Workspace intelligence feeds are not supported on Citrix Workspace app Version 1912.
  • Webcam redirection does not work with Microsoft Teams. This is a limitation because Citrix does not support Microsoft Teams Optimization [MTOP] in Citrix Workspace app for Linux. [RFLNX-3674]

Known issues in 1910

  • When you use the self-service user interface, the Preferences window options might not work as expected. The issue occurs when the libwebkit1 package is unavailable as is the case with Debian 10 buster clients. As a workaround, remove the UIDialogLibWebKit.so library located inside the install/path/lib directory. [RFLNX-3596]
  • Due to architectural changes, you can no longer connect to the cloud store [cloud setup]. Citrix recommends that you use the latest Version of Citrix Workspace app.
