What's new in 4.10.1

High DPI enhancement

With this release, Citrix Receiver for Windows allows the operating system to control the session resolution.

You can apply high DPI in a session but the feature is disabled by default. This means that session scaling follows the operating system resolution. You can configure this feature using the Group Policy Object template and Advanced Preferences dialog. 

For information about configuring DPI scaling, see Configure DPI scaling.

What's new in 4.10

Introducing Citrix Receiver for Windows Store edition

With this release, Citrix is introducing a Store edition of Receiver for Windows. You can download Citrix Receiver for Windows (Store) Version 4.10 from the Microsoft Store. Citrix Receiver for Windows (Store) supports many of the familiar features of the traditional version of Citrix Receiver for Windows, but not all. For a list of supported, unsupported, and partially supported features, see Feature Matrix.

For more information about Citrix Receiver for Windows (Store), see Citrix Receiver for Windows (Store) product documentation.

Expanded tablet mode in Windows 10 using Windows Continuum

Windows Continuum is a Windows 10 feature that adapts to the way the client device is used. Citrix Receiver for Windows Version 4.10 now supports Windows Continuum, including dynamic change of modes.

For touch-enabled devices, the Windows 10 VDA starts in tablet mode when there is no keyboard or mouse attached. It starts in desktop mode when either a keyboard or a mouse or both are attached. Detaching or attaching the keyboard on any client device or the screen on a 2-in-1 device like a Surface Pro toggles between tablet and desktop modes. For more information, see Tablet mode for touchscreen devices in XenApp and XenDesktop documentation.

The Windows 10 VDA detects the presence of a keyboard or a mouse on a touch-enabled client device when you connect or reconnect to a session. It also detects when you attach or detach a keyboard or mouse during the session. This feature is enabled by default on the VDA. To disable the feature, modify the Tablet mode toggle policy using Citrix Studio.

Tablet mode offers a user interface that is better suited to touchscreens:

  • Slightly larger buttons.
  • The Start screen and all apps you start open in a full screen.
  • The taskbar contains a Back button.
  • Icons are removed from the taskbar.
Desktop mode offers the traditional user interface where you interact in the same manner as using a PC with a keyboard and mouse.
 
Note: Web Receivers do not support Windows Continuum features.

Improved protocol driver error messages

With this release, the protocol driver error messages that appear during a connection and SSL-related error messages are improved to include details with appropriate error codes. You can use the error codes to get additional information on the error by running net helpmsg <error code> in the command prompt or refer to the Microsoft System Error codes.

In earlier releases, protocol driver errors were undefined and covered a wide range potential errors. This made it difficult to understand the messages and troubleshoot the errors.

Improved DPI support

Starting with this release, Citrix Receiver for Windows provides improved support for handling high DPI monitors in a session. You can now use multiple monitors with different DPI settings.

 Using this feature, you can scale the sessions to the monitor DPI settings or use the native session’s resolution. High DPI support is available in both application and desktop session.

You can scale the display to the required resolution based on the monitor DPI settings. Seamless applications are scaled as per the monitor DPI settings.

In case of multiple monitors with different DPIs, the seamless application snaps to the most appropriate monitor when moved. This is to avoid graphical conflicts that might occur when applications are running between differently scaled monitors.

By default, DPI scaling is set to enabled. You can configure this feature using the Group Policy Object template and Advanced Preferences dialog. 

For information about configuring DPI scaling, see Configure DPI scaling.

Support for H.265 video encoder mode

Starting with this release, Citrix Receiver for Windows supports the use of the H.265 video codec for hardware acceleration of remote graphics and videos. To benefit from this feature, it must be supported and enabled on both the VDA and Citrix Receiver for Windows. If the GPU on the endpoint does not support H.265 decoding using the DXVA interface, the H265 Decoding for graphics policy settings is ignored and the session falls back to using the H.264 video codec.

Prerequisites

  1. VDA 7.16 and later.
  2. Enable the Optimize for 3D graphics workload policy on the VDA.
  3. Enable the Use hardware encoding for video codec policy on the VDA.

Note: H.265 encoding is supported only on the NVIDIA GPU.

In Citrix Receiver for Windows, this feature is set to Disabled by default.

For information about configuring H.265 video encoding, see Configuring Citrix Receiver for Windows to use H.265 video encoding.

Enhancement to adaptive transport

In earlier releases, when HDXoverUDP is set to Preferred, data transport over EDT is used when possible, with fallback to TCP. 

Starting with this release and 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 but the required underlying UDP transport is unavailable and TCP needs to be used. 

By default, after fallback to TCP, adaptive transport continues to seek EDT every 5 minutes.

Configure NetScaler Gateway using the command line interface

Starting with this release, you can configure the NetScaler Gateway store URL using the command line interface. 

For more information, see Examples of a command line installation.

Option to hide the Advanced Preferences sheet and its contents

Starting with this release, you can customize the availability and the contents of the Advanced Preferences sheet that is present in the right-click menu of the Citrix Receiver icon in the notification area. Doing so ensures that users can apply only administrator-specified settings on their systems. Specifically, can:

  • Hide the Advanced Preferences sheet altogether
  • Hide the following, specific settings from the sheet:
    • Data Collection
    • Connection Center
    • Configuration Checker
    • Local Keyboard Layout Setting
    • DPI Settings
    • Support Info
    • Settings Option

For more information about how to hide the Advanced Preferences sheet and the contents that are present in the Advanced Preferences dialog, see Hiding the Advanced Preferences sheet.

Improved Self-Service plug-in performance

With this release, the Self-Service plug-in launch is improved. The application continues to run in the background even after you close the window.

Support for Workspace configuration

Citrix Receiver for Windows now supports configuring workspaces for subscribers, who might be using one or more services available from Citrix Cloud. 

A workspace is part of a digital workspace solution that enables IT to securely deliver access to apps from any device.
This screenshot is an example of what the workspace experience looks like to your subscribers. This interface is evolving and may look different to what your subscribers are working with today. For example, it might say "StoreFront" at the top of the page instead of "Workspace".
