About this release

What’s new in 2112

Support for cursor color inverting

Previously, the Citrix Workspace app displayed a dotted cursor that appeared the same in color to the black and white background of a text. As a result, it was difficult to locate the position of cursor.

With this release, the cursor color inverts based on the background color of a text. As a result, you can easily locate the position of the cursor in the text. By default, this feature is disabled.

Prerequisites:

  • If .ICAClient is already present in the home folder of the current user:

    Delete All_Regions.ini file

    Or,

    To retain the All_Regions.ini file, add the following lines at the end of the [Virtual Channels\Thinwire Graphics] section:

    InvertCursorEnabled=

    InvertCursorRefreshRate=

    InvertCursorMode=

If the .ICAClient folder is not present then it indicates a fresh install of the Citrix Workspace app. In that case, the default setting for the feature is retained.

To enable this feature, do the following:

  1. Navigate to the $HOME/.ICAClient/wfclient.ini configuration file.
  2. Go to [Thinwire3.0] section and set the following entry:

    InvertCursorEnabled=True

Note:

The cursor does not invert when the value for the Use video codec for compression policy in Citrix Studio is set to Do not use video codec.

Adaptive audio update

Adaptive audio now works when using User Datagram Protocol (UDP) audio delivery. For more information, see Adaptive audio.

Note:

This enhancement requires VDA version 2112 or later.

For information on UDP audio configuration using adaptive audio on Citrix Workspace app, see the Enabling UDP audio section in the Audio documentation.

Support for multiple audio devices (Technical Preview)

Starting with this release, Citrix Workspace app displays all available local audio devices in a session with their names. In addition, plug and play support for Bluetooth and HDMI audio devices is also provided.

This feature is disabled by default. To enable this feature, set the value for AudioRedirectionV4 to True in the module.ini file.

For more information, see Audio.

Note:

Starting with this release, the VdcamVersion4Support attribute in the module.ini file is renamed to AudioRedirectionV4.

UDP audio through Citrix Gateway (Technical Preview)

With this release, Citrix Workspace app supports Datagram Transport Layer Security (DTLS) protocol for UDP audio. As a result, you can access the UDP audio through Citrix Gateway.

To enable UDP audio through Citrix Gateway:

  1. Navigate to the <ICAROOT>/config folder and open the module.ini file.
  2. Go to the [WFClient] section and set the following entry:

    EnableUDPThroughGateway=True

  3. Go to the [ClientAudio] section and set the following entry:

    EnableUDPAudio=True

For more information, see the Enabling UDP audio section in the Audio documentation.

Note:

If you use the StoreFront default.ica configuration, the value of EnableUDPThroughGateway set in the [Application] section takes precedence over the value set in the module.ini file. However, you can set the EnableUDPAudio value in the [ClientAudio] section only using the module.ini file and it does not take precedence over the value set in the StoreFront default.ica configuration.

Enhancement on smart card support

Note:

This enhancement is generally available for Citrix Workspace app.

With this release, Citrix Workspace app supports the Plug and Play functionality for smart card reader.

When you insert a smart card, the smart card reader detects the smart card in the server and client. You can plug and play multiple cards at the same time, and all of these cards are detected.

Prerequisites:

Install the libpcscd library on the Linux client.

Note:

This library might be installed by default in the recent versions of most Linux distributions. However, you might need to install the libpcscd library in earlier versions of some Linux distributions, such as Ubuntu 1604.

To disable this enhancement:

  1. Navigate to the <ICAROOT>/config/module.ini folder.
  2. Go to the SmartCard section.
  3. Set the DriverName= VDSCARDV.DLL.

Enhancements to Microsoft Teams optimization

Note:

The following features are available only after the roll-out of a future update from Microsoft Teams. When the update is rolled-out by Microsoft, you can check CTX253754 for the documentation update and the announcement.

  • Request control in Microsoft Teams

    With this release, you can request control during a Microsoft Teams call when a participant is sharing the screen. Once you have control, you can make selections, edits, or other modifications to the shared screen.

    To take control when a screen is being shared, click Request control at the top of the Microsoft Teams screen. The meeting participant who’s sharing the screen can either allow or deny your request.

    While you have control, you can make selections, edits, and other modifications to the shared screen. When you’re done, click Release control.

  • Support for dynamic e911

    With this release, Citrix Workspace app supports dynamic emergency calling. When used in Microsoft Calling Plans, Operator Connect, and Direct Routing, it provides the capability to:

    • configure and route emergency calls
    • notify security personnel

    The notification is provided based on the current location of the Citrix Workspace app running on the endpoint, instead of the Microsoft Teams client running on the VDA. Ray Baum’s law requires the 911 caller’s dispatchable location to be transmitted to the appropriate Public Safety Answering Point (PSAP). Starting from Citrix Workspace app 2112 for Linux, Microsoft Teams Optimization with HDX is compliant with Ray Baum’s law. To support this feature, the LLDP library must be included in the Operating System distribution of the Thin Client.

What’s new in 2111

What’s new in 2109

Session reliability enhancement

Previously, with HDX Broadcast session reliability, you continue to see a published application’s window if the connection to the application experiences an interruption.

With this release, you can see the screen changes when session reliability begins. The session window is grayed out and a countdown timer shows the time until the next reconnection attempt.

Note:

This feature is supported only for Citrix Virtual Desktops.

Enhancement to logging

Previously, there was no tool available to collect log files in Citrix Workspace app. Log files were present in different folders. You had to manually collect log files from different folders.

Starting with this release, Citrix Workspace app introduces the collectlog.py tool, which lets you collect log files from different folders. You can run this tool using the command line. The log files are generated as a compressed log file. You can download this compressed log file from the local server. For more information see, Logging.

Service continuity

Note:

This feature is generally available 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.

Support for Service continuity with Citrix Workspace Web Extension for Google Chrome

Support for service continuity with the Citrix Workspace Web Extension for Google Chrome is in public technical preview. You can use Workspace Web Extension for Google Chrome with Citrix Workspace app for Linux 2109. This extension is available at Google Chrome web store. The Workspace app communicates with the Citrix Workspace Web extension using the native messaging host protocol for browser extension. Together, the Workspace app and the Workspace Web extension use Workspace connection leases to give browser users access to their apps and desktops during outages. For more information, see Service continuity.

Adaptive audio

With adaptive audio, you don’t need to manually configure the audio quality policies on the VDA. Adaptive audio optimizes settings for your environment and replaces obsolete audio compression formats to provide an excellent user experience. Adaptive audio is enabled by default. For more information, see Adaptive audio.

Note:

If UDP audio delivery is required for real-time audio applications, adaptive audio must be disabled on the VDA to allow fallback to UDP audio delivery.

Storebrowse enhancement for service continuity

Previously, the Workspace connection lease files were synced with files available on the remote server only if you connected using the Self-Service plug-in. As a result, the service continuity feature was not supported when you launched apps or desktop session using storebrowse. Most third-party thin-client vendors use storebrowse to connect to the Workspace platform and the service continuity feature was not enabled for them.

Starting with this release, the Workspace connection lease files sync with files available on the remote server when you connect using storebrowse as well. This feature helps the third-party thin-client vendors to access Workspace even when offline.

Note:

  • This enhancement is available only when service continuity is enabled in cloud deployments. For more information, see the Configure Service Continuity section in the Citrix Workspace documentation.
  • This enhancement is not available if you have set the value of AuthManLiteEnabled to True in the $ICAROOT/config/AuthManConfig.xml file. By default, this value is set to False.

Global App Config Service (Public Technical Preview)

The new Global App Configuration Service for Citrix Workspace allows a Citrix administrator to deliver Workspace service URLs through a centrally managed service.

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


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

For more information on Workspace service URLs settings, see Global App Configuration Service documentation.

Note:

Citrix Workspace app for Linux uses the Global App Configuration Service only to deliver Workspace service URLs.

Enlightened Data Transport (EDT) MTU discovery

Citrix Workspace app now supports Maximum Transmission Unit (MTU) discovery in Enlightened Data Transport (EDT). It increases the reliability and compatibility of the EDT protocol and provides an improved user experience. For more information see, the EDT MTU Discovery section in the Citrix Virtual Apps and Desktops documentation.

Creating custom user-agent strings in network request

With this release, Citrix Workspace app introduces an option to append the User-Agent strings in the network request and identify the source of a network request. Based on this User-Agent strings request, you can decide how to manage your network request. This feature allows you to accept network requests only from trusted devices.

Note:

This feature is supported on cloud deployments of Citrix Workspace app. Also, x86, x64, and armhf are the supported packages.

For more information see, Creating Custom User-Agent in Network Request.

Feature flag management

If an issue occurs with Citrix Workspace app in production, we can disable an affected feature dynamically in Citrix Workspace app even after the feature ships. To do so, we use feature flags and a third-party service called LaunchDarkly. You do not need to make any configurations to enable traffic to LaunchDarkly, unless you have a firewall or proxy blocking outbound traffic. In that case, you enable traffic to LaunchDarkly via specific URLs or IP addresses, depending on your policy requirements.

For more information, see Feature flag management.

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 the 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 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. However, 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 do 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 the 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

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 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 the 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 the 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 the 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 might 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.
