About this release

What’s new in 2009.6

Support for FIDO2 authentication

FIDO2 authentication lets users take advantage of the local endpoint FIDO2 components. Users can now authenticate using FIDO2 security keys or integrated biometrics. Devices must have Trusted Platform Module (TPM) 2.0 and Windows Hello. For more information, see FIDO2: WebAuthn & CTAP.

Microsoft Teams enhancements

  • Microsoft Teams now displays previously used peripheral devices in the Preferred devices list.
  • The WebRTC media engine accurately determines the maximum encoding resolution possible on an endpoint. The WebRTC media engine estimates multiple times a day and not only on first launch.
  • The Citrix Workspace app installer is now packaged with the Microsoft Teams ringtones.
  • Echo cancellation improvements - Reduced echo level when a peer has a speaker or microphone that generates an echo.
  • Screen sharing improvements - Now when you do screensharing, only the Desktop Viewer screen is captured in native bitmap format. Previously, client local windows that overlaid on top of the Desktop Viewer window were blacked out.

What’s new in 2009

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

What’s new in 2008

Group Policy Object (GPO) administrative template configuration for keyboard layout and language bar

In addition to the existing GUI method, you can now configure the keyboard layout and language bar using the Group Policy Object (GPO) administrative template.

For more information, see Keyboard layout and language bar.

CryptoKit update

Citrix Workspace app now supports Version 14.2.1 of the CryptoKit.

Language support

Citrix Workspace app for Windows is now available in the Portuguese (Brazil) language.

Authentication enhancement

To provide a seamless experience, the authentication dialog now appears inside Citrix Workspace app. The Store details appear on the logon screen. Authentication tokens are encrypted and stored so that you don’t need to reenter the credentials in case of a system reboot or session restart.

Note:

This authentication enhancement is applicable only in cloud deployments.

Enhancement to app protection

In earlier releases, when you are trying to take a screenshot of a protected window, the entire screen, including the non-protected apps in the background, are blacked out.

Now, when you are taking a screenshot using a snipping tool, only the protected window is blacked out. You can take a screenshot of the area outside the protected window.

However, if you are using the PrtScr key to capture a screenshot on a Windows 10 device, you must minimize the protected window.

Additionally, this release addresses issues to improve the app protection feature.

Enhancement to Browser Content Redirection

  • Cookies are now persistent across the sessions: When you exit and relaunch a browser, you are not prompted to reenter your credentials.
  • Browsers now honor the local system language.

What’s new in 2006.1

Support for Dual Tone Multi Frequency (DTMF) with Microsoft Teams

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.

Enhancement to Microsoft Teams screen sharing

With this release, the contents shared using Microsoft Teams are limited to the contents of the Desktop Viewer window. Areas outside the Desktop Viewer window are cropped, and the client’s local apps that overlap the Desktop Viewer appear blacked out.

For more information, see Screen sharing.

Update to Citrix Analytics Service

Citrix Workspace app is instrumented to securely 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.

What’s new in 2002

App protection

Disclaimer

App protection policies work by filtering access to required functions of the underlying operating system (specific API calls required to capture screens or keyboard presses). This means that app protection policies provide protection even against custom and purpose-built hacker tools. However, as operating systems evolve, new ways of capturing screens and logging keys emerge. While we continue to identify and address them, we can’t guarantee full protection in specific configurations and deployments.

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

Note:

Citrix recommends that you only use the native Citrix Workspace app to launch a protected session.

App protection is configured between StoreFront and the Controller using the Controller. For information about configuring app protection on the Controller, see App protection in Citrix Virtual Apps and Desktops documentation. This configuration is then applied to Citrix Workspace app by including the app protection component using any of the following methods:

  • GUI
  • Command-line interface

You can include the app protection component both during the Citrix Workspace app installation or on-demand installation.

Note:

  • This feature is supported only on Microsoft Windows Desktop operating systems such as Windows 10, Windows 8.1, and Windows 7.
  • This feature is not supported over Remote Desktop Protocol (RDP).

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

Installer enhancement

In earlier releases, if an administrator tried to install Citrix Workspace app on a system that has a user-installed instance of the app, the installation was blocked.

With this release, the administrators can now override the user-installed instance of Citrix Workspace app and continue with the installation successfully.

Enhancement to Citrix Workspace Updates

In earlier releases, if Citrix Workspace app is installed by an administrator, a non-administrator might not update it.

With this release, a non-administrator can update Citrix Workspace app on an admin-installed instance. You can do that by right-clicking the Citrix Workspace app icon in the notification area and selecting Check for Updates.

Note:

The Check for Updates option is now available on both the user-installed and the admin-installed instances of Citrix Workspace app.

Support for outbound proxy

SmartControl allows administrators to define granular policies to configure and enforce user environment attributes for Citrix Virtual Apps and Desktops using Citrix Gateway. For instance, you might want to prohibit users from mapping drives to their remote desktops. This can be achieved using the SmartControl feature on Citrix Gateway.

However, the scenario changes when Citrix Workspace app and Citrix Gateway belong to separate enterprise accounts. In such scenarios, the client domain cannot apply the SmartControl feature because the gateway does not exist on the client domain. Instead, you can use the Outbound ICA Proxy. Outbound ICA Proxy lets you use the SmartControl feature even when Citrix Workspace app and Citrix Gateway are deployed in different organizations.

Citrix Workspace app supports session launches using the Citrix ADC LAN proxy. Either a single, static proxy can be configured or the proxy server can be selected at runtime using the outbound proxy plug-in.

You can configure outbound proxies using the following methods:

  • Static proxy: Proxy server is configured by providing a proxy host name and port number.
  • Dynamic proxy: A single proxy server can be selected among one or more proxy servers using the proxy plug in DLL.

You can configure the outbound proxy using the Group Policy Object administrative template and the Registry editor.

For more information about outbound proxy, see Outbound ICA Proxy support in the Citrix Gateway documentation.

For more information about configuring the outbound proxy, see Outbound proxy.

Citrix Embedded Browser binaries

You can now exclude the Citrix Embedded Browser binaries so as to not use this feature.

This release introduces a command-line switch to exclude the Citrix Embedded Browser binaries. Run the /InstallEmbeddedBrowser=N switch from the Citrix Workspace app install location to discontinue the embedded browser feature.

You can exclude the Citrix Embedded Browser binaries only in the following cases:

  • Fresh install
  • Upgrade from a version that does not include the Citrix Embedded Browser binaries.

If your version of Citrix Workspace app includes the Citrix Embedded Browser binaries and you are upgrading to Version 2002, the embedded browser binaries are automatically updated during the upgrade.

Enhancement to desktop sharing with Microsoft Teams

When you share your workspace using Microsoft Teams, Citrix Workspace app displays a red border that surrounds the area of the monitor that is currently being shared. You can share only the Desktop Viewer window, or any local window overlaid on top of it. When you minimize the Desktop Viewer window, screen sharing is paused.

Endpoint encoder performance estimator on Microsoft Teams

When the HdxTeams.exe process (the WebRTC media engine embedded in Citrix Workspace app that handles Microsoft Teams redirection) is launched, it estimates the best encoding resolution that the endpoint’s CPU can sustain without overloading. Possible values are 240p, 360p, 720p and 1080p.

The performance estimation process (also called webrtcapi.EndpointPerformance) runs when HdxTeams.exe initializes. The macroblock code determines the best resolution that can be achieved with a particular endpoint. The highest possible resolution is then included during the codec negotiation between the peers, or between the peer and the conference server.

For information on configuring endpoint encoder, see Endpoint encoder performance estimator on Microsoft Teams.

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

Enhancement to Citrix Analytics Service

With this release, Citrix Workspace app is instrumented to securely transmit the public IP address of the most recent network hop to Citrix Analytics Service. This data is collected per session launch. It helps Citrix Analytics Service to analyze whether poor performance issues are tied to specific geographic areas.

By default, the IP address logs are sent to Citrix Analytics Service. However, you can disable this option on the Citrix Workspace app using the Registry editor.

To disable IP address log transmissions, navigate to the following registry path and set the SendPublicIPAddress key to Off.

  • On 64-bit Windows machines, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle.
  • On 32-bit Windows machines, navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Dazzle.

Note:

  • IP address transmissions are best-case efforts. Although Citrix Workspace app transmits every IP address that it is launched on, some of the addresses might not be accurate.
  • In closed customer environments, where the endpoints are operating within an intranet, ensure that the URL https://locus.analytics.cloud.com/api/locateip is whitelisted on the endpoint.

For more information on how Performance Analytics uses this information, see Self-Service for Performance.

  • You are upgrading from an unsupported version of Citrix Workspace app.
  • The installation or upgrade is unsuccessful.

Note:

/forceinstall switch is the replacement for /rcu switch.

For more information, see Common parameters in the Install section.

What’s new in 1907

Desktop sharing on Microsoft Teams

With this release, Citrix Workspace app supports screen sharing on desktop-based Microsoft Teams using Citrix Virtual Apps and Desktops.

You can share the Desktop Viewer window without sharing the local desktop. If the Desktop Viewer is set to Full Screen mode and is spanning across multiple monitors, the default monitor is shared.

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

Additionally, this release also addresses a number of issues that help to improve overall performance and stability.

What’s new in 1905

Managing Secure Browser cache with multiple users

When multiple users share device to log in, one user’s cache carries forward to the next user, thereby sharing browsing information across users.

To address this issue, Citrix Workspace app introduces a new Group Policy Object (GPO) administrative policy. This policy disallows the storing of the browser cache on the local device.

For more information, see SaaS apps

Support for Local Security Authority (LSA) protection

Citrix Workspace app now supports Windows Local Security Authority (LSA) protection, which maintains information about all aspects of local security on a system. This support provides the LSA level of system protection to hosted desktops.

Optimization for Microsoft Teams

Note:

This feature depends on a future Microsoft Teams release. We will update this description as information about the version and release date become available.

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, we bundle all necessary components for optimization for Microsoft Teams into the VDA and the Workspace app for Windows. For more information, see Optimization for Microsoft Teams and Policies.

Legacy TWAIN enhancements

We made significant enhancements to the overall code quality to bring more stability and reliability to the legacy TWAIN feature.

New time zone control policy

The Restore desktop OS time zone on session disconnect or logoff policy setting specifies the time zone behavior when a user disconnects or logs off from a single session. For more information, see Restore desktop OS time zone on session disconnect or logoff.

What’s new in 1904.1

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

What’s new in 1904

.NET Framework version upgrade

This release requires .NET Framework Version is 4.6.2 or later. If you are trying to install or upgrade to Citrix Workspace app 1904 or later and the requisite version of the .NET Framework is not available on your Windows system, the Citrix Workspace app installer will download and install the required version of the .NET Framework.

Note:

If you are trying to install or upgrade Citrix Workspace app with non-administrator privileges and .NET Framework 4.6.2 or greater is not present on the system, the installation fails.

Changes in the Citrix Workspace app installer package

In earlier releases, the Microsoft Visual C++ Redistributable binaries were packaged individually with the Citrix Workspace app installer. The binaries were copied locally inside the Citrix Workspace app installation folder during the Citrix Workspace app installation.

This release requires Microsoft Visual C++ Redistributable 14.16.27012.6 or later. Starting with Version 1904, Microsoft Visual C++ Redistributable individual binaries are no longer packaged with the Citrix Workspace app installer. Instead, the Citrix Workspace app installer includes the Microsoft Visual C++ Redistributable 14.16.27012.6 installer. When you install Citrix Workspace app, the Citrix Workspace app installer checks whether the Microsoft Visual C++ Redistributable package is present on the system and installs it if necessary.

Note:

If you are trying to install Citrix Workspace app with non-administrator privileges, and the Microsoft Visual C++ Redistributable package is not present on the system, the installation fails.

Only an administrator can install the Microsoft Visual C++ Redistributable package.

For troubleshooting issues with the .NET Framework or the Microsoft Visual C++ Redistributable installation, see Citrix Knowledge Center article CTX250044.

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.

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)
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013)

DTLS v1.0 supports the following cipher suites:

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
  • TLS_EMPTY_RENEGOTIATION_INFO_SCSV

DTLS v1.2 supports the following cipher suites:

  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
  • TLS_EMPTY_RENEGOTIATION_INFO_SCSV

What’s new in 1903

Updated framework

Updated the Citrix Secure Browser engine to include the latest security updates, to ensure better security and performance when accessing secure SaaS apps.

What’s new in 1902

Note:

This release of Citrix Workspace app for Windows is aligned with Citrix Virtual Apps and Desktop Version 7 1903 release.

Enhancement to relative mouse configuration

The relative mouse feature determines how far the mouse has moved since the last frame within a window or screen. The relative mouse uses the pixel delta between the mouse movements. For example, when you change the direction of the camera using mouse controls, the feature is efficient. Also, apps often hide the mouse cursor because the position of the cursor relative to the screen coordinates is not relevant when manipulating a 3-D object or scene.

So far, the user can enable or disable the feature from the Desktop Viewer and it is available on a per-session basis. Starting with this release, you can configure the feature both on a per-user and a per-session basis. This gives you more granular control on the availability of the feature.

For more information, see Relative mouse.

Introducing new SDK

The Certificate Identity Declaration (CID) SDK is being introduced with this release. The CID SDK lets developers create a utility using which Citrix Workspace app can authenticate to the StoreFront server by using the certificate installed on the client machine.

For more information, see Certificate Identity Declaration SDK for Citrix Workspace app for Windows documentation.

Support for copy and paste between sessions and clients

Using Citrix Virtual Apps and Desktops 1903 and the latest version of Citrix Workspace app for Windows, users can now copy and paste files, directories, or groups of files or directories between a session and a local client. Copy and paste functions work by using the right-click menu or keyboard shortcuts.

Limitations:

  • Cut is not supported. Requests to cut a file are treated as copy.
  • Drag is not supported.
  • If a copy is initiated from one direction (client to VDA or VDA to client) initially and the other is attempted, the first operation closes without any information to the user when the second one starts – irrespective of the same or different files.

DPI matching on Windows Server 2016 and Windows Server 2019

DPI matching allows the Windows Server 2016 or Windows Server 2019 desktop session to match the DPI of the endpoint when using Citrix Workspace app for Windows.

Note:

This setting is off by default. DPI matching is enabled whenever the DPI scaling setting is set to No. When using seamless apps, the DPI is set to 100% by default.

Fast smart card support

Fast smart card is an improvement over the existing HDX PC/SC-based smart card redirection. It improves performance when smart cards are used in high-latency WAN environments.

Fast smart cards are supported on Linux VDA only and by the following version of Citrix Workspace app:

  • Citrix Receiver for Windows 4.12
  • Citrix Workspace app 1808 for Windows and later

To enable fast smart card logon on Citrix Workspace app:

Fast smart card logon is enabled by default on the VDA and disabled by default on Citrix Workspace app. To enable fast smart card logon, include the following parameter in the default.ica file of the associated StoreFront site:

copy[WFClient]
SmartCardCryptographicRedirection=On

To disable fast smart card logon on Citrix Workspace app:

To disable fast smart card logon on Citrix Workspace app, remove the SmartCardCryptographicRedirection parameter from the default.ica file of the associated StoreFront site.

For more information, see smart-cards.

What’s new in 1812

Updated framework

The Chromium embedded framework on which Citrix Secure Browser is built is updated to Version 70. This results in a better user experience when accessing secure SaaS apps.

What’s new in 1811

Note:

Version 1811 of Citrix Workspace app is packaged with Citrix Virtual Apps and Desktops 7 1811. It is not available separately for download. All features and functionality of Version 1811 are also included in Version 1812.

Virtual display layout

This feature lets you define a virtual monitor layout that applies to the remote desktop and to virtually split a single client monitor into up to eight monitors on the remote desktop. You can configure the virtual monitors on the Monitor Layout tab in the Desktop Viewer. There, you can draw horizontal or vertical lines to separate the screen into virtual monitors. The screen is split according to specified percentages of the client monitor resolution.

You can set a DPI for the virtual monitors that is used for DPI scaling or DPI matching. After applying a virtual monitor layout, resize or reconnect the session.

This configuration applies only to full-screen, single-monitor desktop sessions, and does not affect any published applications. This configuration applies to all subsequent connections from this client.

Display graphics mode indicator

The Display graphics mode indicator policy has been updated to replace the display lossless indicator policy.

This setting configures the graphics mode indicator to run in the user session. It allows you to see details about the graphics mode in use, including graphics provider, encoder, hardware encoding, image quality, progressive display status, and lossless text.

By default, the Display graphics mode indicator policy is disabled. It replaces the Display lossless indicator policy of earlier releases, which was enabled by default.

DPI matching on Windows 10

DPI matching allows the Windows 10 desktop session to match the DPI of the endpoint when using Citrix Workspace app for Windows.

Note:

This setting is disabled by default. DPI matching is enabled whenever the DPI scaling setting is set to No. When using VM hosted apps, the DPI is set to 100% by default.

HDX adaptive throughput

HDX adaptive throughput intelligently fine-tunes the peak throughput of the ICA session by adjusting output buffers. The number of output buffers is initially set at a high value. This high value allows data to be transmitted to the client more quickly and efficiently, especially in high latency networks.

Providing better interactivity, faster file transfers, smoother video playback, higher framerate, and resolution results in an enhanced user experience.

Session interactivity is constantly measured to determine whether any data streams within the ICA session are adversely affecting interactivity. If that occurs, the throughput is decreased to reduce the impact of the large data stream on the session and allow interactivity to recover.

This is feature is supported only on Citrix Workspace app 1811 for Windows and later.

Important:

HDX adaptive throughput changes the way that output buffers are set by moving this mechanism from the client to the VDA. Therefore, adjusting the number of output buffers on the client as described in CTX125027 has no effect.

Client drive-mapping performance improvement

Client drive mapping now supports the transfer of data between the host and the client as a stream. This enhancement ensures that the file transfer adapts to the changing network throughput conditions. It also uses any available extra bandwidth to scale up the data transfer rate.

By default, this feature is enabled. These improvements require Citrix Workspace app for Windows 1811 or later.

To disable this feature, set the following registry key and then restart the server:

Path: HKEY_LOCAL_MACHINE\System\Currentcontrolset\services\picadm\Parameters Name: DisableFullStreamWrite Type: REG_DWORD Value: 0x01 - disables 0 or delete - enables

What’s new in 1810

Option to choose Citrix Files download location

Citrix Workspace app lets you select the download location for Citrix Files. Earlier, the download location for Citrix Files, by default, was set to the Downloads folder. Now, the download location is configurable.

You can set the download location using either the Advanced Preferences dialog or the Registry editor.

For information about configuring Citrix Files download location using the Registry editor, see Configure download location for Citrix Files using the Registry editor.

For information about configuring Citrix Files download location using Advanced Preferences dialog, see Configuring download location using Advanced Preferences in Citrix Workspace app for Windows Help documentation.

Additionally, this release address a number of fixes relating to installation, launch and Citrix Workspace app for Citrix Cloud.

What’s new in 1809

Support for Citrix Ready workspace hub for Citrix Casting

The Citrix Ready workspace hub combines digital and physical environments to deliver apps and data within a secure smart space. The complete system connects devices (or things), like mobile apps and sensors, to create an intelligent and responsive environment.

Citrix Ready workspace hub is built on the Raspberry Pi 3 platform. The device running Citrix Workspace app connects to the Citrix Ready workspace hub and casts the apps or desktops on a larger display. Citrix Casting is supported only on Microsoft Windows 10 Version 1607 and later or Windows Server 2016.

Using the Advanced Preferences dialog, you can configure whether you want to launch Citrix Ready workspace hub when Citrix Workspace app is launched.

Note:

  • Citrix Casting for Windows supports Citrix Ready workspace hub Version 2.40.3839 and later. Workspace hub with earlier versions might not get detected or cause a casting error.
  • The Citrix Ready workspace hub feature is not supported on Citrix Workspace app for Windows (Store).

For more information about Citrix Ready workspace hub in Citrix Workspace app for Windows, see Configuring Citrix Ready workspace hub.

For more information about Citrix Ready workspace hub, see the Citrix Ready workspace hub section in the Citrix Virtual Apps and Desktops documentation.

What’s new in 1808

Secure SaaS with embedded Citrix Secure Browser

Secure access to SaaS applications provides a unified user experience that delivers published SaaS applications to the users. SaaS apps are available with single sign-on. Administrators can now protect the organization’s network and end-user devices from malware and data leaks by filtering access to specific websites and website categories.

Citrix Workspace app for Windows support the use of SaaS apps using the Access Control Service. The service enables administrators to provide a cohesive experience, integrating single sign-on, and content inspection.

Delivering SaaS apps from the cloud has the following benefits:

  • Simple configuration – Easy to operate, update, and consume.
  • Single sign-on – Hassle-free log on with single sign-on.
  • Standard template for different apps – Template-based configuration of popular apps.

For information on how to configure SaaS apps using Access Control Services, see the Access Control documentation.

For more information about SaaS apps with Citrix Workspace app, see Workspace configuration.

Single sign-on support with Citrix Gateway

Single sign-on lets you authenticate to a domain and use Citrix Virtual Apps and Desktops delivered by that domain without having to reauthenticate to each app or desktop. When you add a store using the Storebrowse utility, your credentials are passed through to the Citrix Gateway server, along with the apps and desktops enumerated for you, including your Start menu settings. After configuring single sign-on, you can add the store, enumerate your apps and desktops, and launch the required resources without having to type your credentials multiple times.

For information about configuring single sign-on with Citrix Gateway, see Configuring single sign-on with Citrix Gateway.

Beacon test

With this release, Citrix Workspace app allows you to perform a beacon test using the Beacon checker that is available as part of the Configuration Checker utility. Beacon test helps to confirm if the beacon (ping.citrix.com) is reachable. This diagnostic test helps to eliminate one of the many possible causes for slow resource enumeration, that is beacon not being available.

To run the test, right-click the Citrix Workspace app in the notification area and select Advanced Preferences > Configuration Checker. Select Beacon checker from the list of Tests and click Run.

The test results can be any of the following:

  • Reachable – Citrix Workspace app is successfully able to contact the beacon.
  • Not reachable - Citrix Workspace app is unable to contact the beacon.
  • Partially reachable - Citrix Workspace app is able to contact the beacon intermittently.

Note:

  • The test results are not applicable on workspace for web.
  • The test results can be saved as reports. The default format for the report is .txt.

Storebrowse utility for Citrix Workspace app

Storebrowse is a lightweight command-line utility that is used to interact between the client and the server. It is used to authenticate all the operations within StoreFront and with Citrix Gateway.

Using the Storebrowse utility, administrators can automate the following day-to-day operations:

  • Add a store.
  • Enumerate the published desktops and applications from a configured store.
  • Generate an ICA file manually by selecting any published desktop or application.
  • Generate an ICA file using the Storebrowse command line.
  • Launch the published application.

The Storebrowse utility is part of the Authmanager component. After installing the Citrix Workspace, the Storebrowse utility is located in the AuthManager installation folder. For more information, see the Storebrowse section.

Support for PDF printing

With this release, Citrix Workspace app for Windows supports PDF printing in a session. The Citrix PDF Universal Printer driver allows you to print documents that are launched using hosted applications and desktops running on Citrix Virtual Apps and Desktops.

When you select the Citrix PDF Printer option from the Print dialog, the printer driver converts the file to a PDF and transfers the PDF to the local device. The PDF is then launched using the default PDF viewer for viewing and prints from a locally attached printer.

Citrix recommends the Google Chrome browser or Adobe Acrobat Reader for PDF viewing.

You can enable Citrix PDF printing using Citrix Studio on the Delivery Controller.

For information about how to configure PDF printing, see PDF printing.

Chrome enhancement to browser content redirection

Browser content redirection now supports the Google Chrome browser in addition to the previously supported Internet Explorer browser. Browser content redirection redirects the contents of a web browser to a client device, and creates a corresponding browser embedded within the Citrix Workspace app. This feature offloads network usage, page processing, and graphics rendering to the endpoint. Doing so improves the user experience when browsing demanding webpages, especially webpages that incorporate HTML5 or WebRTC video.

For more information, see Browser content redirection.

Better network throughput over high latency connections

The default number of ICA output buffers that are used to send and receive data has been raised from 44 (64 Kilobytes) to 100 (~145 Kilobytes). This change delivers improved throughput performance even on high latency connections. This enhancement applies to only Citrix Workspace app 1808 for Windows or later.

For more details, see CTX125027.

Client drive-mapping support for large file transfers

Client drive mapping now supports transfers of files larger than 4 Gigabytes. The required minimum version for Citrix Workspace app for Windows is 1808.

Support for Citrix Analytics

Citrix Workspace app is instrumented to securely transmit logs to Citrix Analytics. The logs are analyzed and stored on Citrix Analytics servers when enabled. For more information about Citrix Analytics, see Citrix Analytics.
