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: 1 export DEBIAN_FRONTEND=”noninteractive” 2 sudo debconf-set-selections <<< ”icaclient app_protection/ install_app_protection select no” 3 sudo debconf-show icaclient 4 * app_protection/install_app_protection: no 5 sudo apt install -f ./icaclient_<version>._amd64.deb Microsoft Teams enhancements • The Citrix Workspace app installer is now packaged with the Microsoft Teams ringtones. • 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. • Audio output switches automatically to newly plugged-in audio devices, and an appropriate audio volume is set. • HTTP proxy support for anonymous authentication. © 1999-2021 Citrix Systems, Inc.

Starting with this release, Citrix Workspace app allows you to configure per-store CDM file access. Note: The file access setting isnt’ 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 Desk- tops. 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 cre- dentials 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. © 1999-2021 Citrix Systems, Inc. All rights reserved. 4 Citrix Workspace app for Linux 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 dynami- cally 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 Cit- rix 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: © 1999-2021 Citrix Systems, Inc. All rights reserved. 5 Citrix Workspace app for Linux • 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 forMi- crosoft Skype for Business. The difference is that, we bundle all the necessary components forMi- crosoft 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 © 1999-2021 Citrix Systems, Inc. All rights reserved. 6 Citrix Workspace app for Linux 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 sec- tions 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 un- compressed, 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. © 1999-2021 Citrix Systems, Inc. All rights reserved. 7 Citrix Workspace app for
