What’s new in Citrix Workspace app for Linux

What’s new in 1903

Cryptographic update

This feature is an important change to the secure communication protocol. Cipher suites with the prefix TLS_RSA_ do not offer forward secrecy and are considered weak. These cipher suites were deprecated in Citrix Receiver version 13.10 with an option for backward compatibility.

In this release, the TLS_RSA_ cipher suites have been removed entirely. Instead, this release supports the advanced TLS_ECDHE_RSA_ cipher suites. If your environment is not configured with the TLS_ECDHE_RSA_ cipher suites, client launches are not supported due to weak ciphers. This release supports 1536-bit RSA keys for client authentication.

The following advanced cipher suites are supported:

  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)

For more information see, Configuring cipher suites.


From version 1903 and later, DTLS is supported from Citrix Gateway 12.1 and later. For information on DTLS supported cipher suites for Citrix Gateway, see Support for DTLS protocol

Bloomberg audio redirection

This feature allows the use of Bloomberg v4 audio interfaces across multiple sessions. The audio from the sessions now goes through the optimized channel to the Bloomberg interface. The fingerprint interface is redirected to a single session as before.


By default, this feature is disabled for the x86, x64, and for ARMHF platforms.

For more information on how to configure Bloomberg audio redirection, follow the steps mentioned under Bloomberg v4 keyboard redirection through generic USB and with selective redirection support.

Sign-on page

This release introduces a new sign-on page in the self-service user interface.

Disconnect time

This release addresses issues that help to significantly improve the disconnect time.

What’s new in 1901

Support for Citrix Analytics

Citrix Workspace app for Linux is instrumented to securely transmit logs to Citrix Analytics when certain events are triggered by the app. The logs are analyzed and stored on Citrix Analytics servers when enabled. For more information about Citrix Analytics, see Citrix Analytics.

Workspace launcher with Citrix Gateway

Citrix introduced Workspace launcher (WebHelper) in version 1809. In version 1901, Citrix Workspace launcher works not only with direct connections to StoreFront, but also through Citrix Gateway. This feature helps to launch the ICA file automatically and to detect the Citrix Workspace app installation.

Logging enhancements II

Logging enhancements II is an extension of the Logging enhancements and Better logging features. The feature introduces support for logging for many modules and simplifies the process of collecting logs. It helps users troubleshoot, and - in cases of complicated issues - facilitates support by providing detailed logs.

For information about enabling logging, see Enabling logging.

Keyboard layout synchronization between client and VDA

Previously, the keyboard layouts on the Windows or Linux VDA and on the client device were synchronized manually. For example, when the keyboard layout changed from English to French on the client device but not on the VDA, key mapping issues could occur and persist until the keyboard layout on the VDA was changed to French too.

Starting with this release, Citrix is addressing the issue by automatically synchronizing the keyboard layout of the VDA with that of the client device. Anytime the keyboard layout on the client device changes, the layout on the VDA follows automatically.


This feature requires version 7.16 or later of the VDA.

For more information, see Keyboard layout synchronization between client and VDA.

What’s new in 1810

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

What’s new in 1809

Connecting this version of Citrix Workspace app for Linux to Citrix Workspace services is an experimental feature.

Introducing Workspace launcher

Previously, the browser plug-in provided along with Citrix Workspace app for Linux enabled users to launch published desktops and applications. This plug-in was based on the Netscape Plugin Application Programming Interface (NPAPI).

Mozilla Corporation has announced that NPAPI support is deprecated as of version 52 of the Firefox browser. Other browsers, too, have deprecated support for NPAPI.

As a solution, Citrix is introducing Workspace launcher (WebHelper). To enable this feature, configure StoreFront to send requests to Workspace launcher in order to detect the Citrix Workspace app installation.

For information about configuring StoreFront, see Solution – 2 > a) Administrator configuration in Knowledge Center article CTX237727.


Citrix Workspace launcher currently works only with direct connections to StoreFront. It is not supported in other cases such as connections through Citrix Gateway.

Disabling new workspace web UI mode

When you launch the Citrix Workspace app for Linux using self-service executable file from third-party thin client vendors, the application can become unresponsive due to 100% CPU utilization.

As a workaround, to switch back to the old UI mode:

  1. Remove cached files by using the command:

    rm -r ~/.ICAClient

  2. Go to $ICAROOT/config/AuthManconfig.xml file.
  3. Change CWACapableEnabled key value to false.
  4. Launch Citrix Workspace app for Linux. Observe that the self-service executable file loads the old UI.

What’s new in 1808

Citrix Workspace app

Citrix Receiver is now Citrix Workspace app. Citrix Workspace app extends the user experience you have enjoyed with Citrix Receiver, making it easier for you to stay productive. Citrix Workspace app incorporates the full capabilities of Citrix Receiver and lays the groundwork for new capabilities for future Citrix Virtual Apps and Desktops releases as well as the comprehensive Citrix Workspace.

Citrix Workspace app has simplified versioning based on the YYMM format, which makes this release of Citrix Workspace app 1808. The previous release had file version number

Existing users or endpoints of Citrix Receiver for Linux can seamlessly transition to this new version of Citrix Workspace app for Linux by doing an in-place upgrade.

Upgrading to Citrix Workspace app:

  • Download the Citrix Workspace app from the Citrix download page and install the app to upgrade from Citrix Receiver to Citrix Workspace app.

Citrix Workspace app has a new icon set in a blue theme. It replaces the earlier Citrix Receiver icon that had a black theme.

The Citrix Workspace screen overlay appears on the first launch of the app or when you upgrade and when you uninstall and reinstall the app, to inform you about the transition. You can either click Got it to continue using the Workspace app, or click Learn more to find out more details.

Connecting this version of Citrix Workspace app for Linux to Citrix Workspace services is an experimental feature.

Bloomberg v4 keyboard selective redirection support

This feature allows the use of the Bloomberg v4 keyboard interface across multiple sessions. This functionality provides flexibility to use the keyboard in all remote sessions except the fingerprint and audio interfaces. The fingerprint and audio interfaces are redirected to single sessions as before.


By default, this feature is enabled for x86 and x64 platforms and is disabled for ARMHF platforms.

For more details, see Bloomberg v4 keyboard selective redirection support.
