Citrix Workspace app for Linux 2106 - Technology Preview

Note: This is an Early Access Build shared for the purpose of testing/validation with the intent to make organizations ready for the upcoming release and is NOT advised to be deployed in production environments. 

We are excited to share with you the Early Access Release of our next version of Citrix Workspace app for Linux.

Please provide your feedback here before 7th June 2021.

What’s new with EAR build:     

Chromium Embedded Framework (CEF) for Browser Content Redirection (BCR) changes.

The CEF-based BCR is now fully functional. By default, CEF-based BCR is enabled. 

Customers can replace libffmpeg.so provided in the Workspace app package with a suitable libffmpeg.so that has the required codecs, in the path $ICAROOT/cef/libffmpeg.so. 

Battery status indicator

The battery status of the device is now displayed in the notification area of a Citrix Windows Desktop session. 

Note: Battery status indicator is not displayed for server VDA 

By default, the battery status indicator is enabled. 

To disable the battery status indicator: 

Navigate to the \<ICAROOT\>/config/module.ini folder. 

Go to the ICA 3.0 section. 

Set the MobileReceiver = Off 

App protection enhancement (Experimental)

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 

Configuring app protection for authentication manager: 

Navigate to $ICAROOT/config/AuthManConfig.xml and edit as required:

/opt/Citrix/ICAClient/config$ cat AuthManConfig.xml | grep -I authmananti -A 1 

<key>AuthManAntiScreenCaptureEnabled</key> 

<value>true</value> 

<key>AuthManAntiKeyLoggingEnabled</key> 

<value>true </value> 

Configuring app protection for the Self-Service plug-in interface: 

Navigate to $ICAROOT/config/AuthManConfig.xml and edit as required:  

/opt/Citrix/ICAClient/config$ cat AuthManConfig.xml | grep -I protection -A 4 

<!-- Selfservice app protection configuration--> 

<Selfservice> 

<AntiScreenCaptureEnabled>true</AntiScreenCaptureEnabled> 

<AntiKeyLoggingEnabled>true</AntiKeyLoggingEnabled> 

</Selfservice> 

Microsoft Teams enhancement

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

Navigate to  

\HKEY_CURRENT_USER\SOFTWARE\Citrix\HDXMediaStream  

And create the key by name NetworkPreference (REG_DWORD). 

Select one of the following values as required: 

1- Ethernet 

2- WiFi 

3- Cellular 

4- VPN 

5- Loopback 

6- Any 

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

Service continuity (Technical Preview)

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.
