Citrix Receiver for Windows provides users with secure, self-service access to virtual desktops and apps provided by XenDesktop and XenApp.
Enhanced RealTime Media Engine (RTME) integration
This release introduces enhancements to the Citrix Receiver for Windows installation paradigm by incorporating RTME into a single download and installation package. Previously, users needed to install Citrix Receiver, then launch a separate MSI installation package to integrate RTME functionality in Receiver.
This created a less desireable user experience which impeded widespread adoption of the HDX RealTime Optimization Pack in some organizations; BYOD users (and remote workers) needed to install Citrix Receiver first, then return to the Citrix download page to invoke another separate installer for the HDX RTME. A single installer now combines the latest Citrix Receiver for Windows with the HDX RTME installer.
Refer to the installation article for information about using the latest Citrix Receiver installer with HDX RTME in a single executable.
Set the transparency level using session reliability group policy
This release introduces enhancements to session reliability group policy. When configuring session reliability group policy, you can now set the transparency level applied to a published app (or desktop) during the session reliability reconnection period. See Session reliability and group policy in the Configure Receiver with the Group Policy Object Template topic for more information.
Manual fallback to server rendering
At this release, Citrix Receiver implements manual fallback to server rendering on the client. In some situations when viewing Flash content, a client may experience a black screen and have no way to view the Flash video. In most cases, if Flash fails to render on the client, it will fall back to server-side rendering automatically. However, in some situations, client-side rendering fails and it also fails to fallback.
To resolve such situations, Citrix Receiver for Windows now provides an option for a user to manually refresh the screen and force server-side rendering of the Flash content. To manually fallback, place the cursor in the black Flash window and right click to display a context menu containing an option to "Reload content". The image below illustrates this new functionality.
Upgrade SSL SDK libraries to support NIST SP800-52
Citrix Receiver now provides an upgraded SSL SDK library to include support for NIST SP800-52. This functionallity allows Receiver to support the NIST SP800-52 compliance mode for TLS connections. For more information, see Enable NIST SP800-52 compliance mode in the To set client permissions topic. For additional information on session reliability, see Session reliability and group policy in the Configure Receiver with the Group Policy Object Template topic.
Improved upgrade process
This release of Citrix Receiver for Windows provides an updated installer that retains existing client settings, improving the user experience when moving from previous versions of Citrix Receiver. In addition, the updated installer seamlessly upgrades from previously installed versions.
Auto-client reconnect and session reliability improvements
These improvements enable better interoperability with CloudBridge and NetScaler Gateway. A session can reconnect using auto-client reconnect and session reliability regardless of the connection path. The specific improvements for this release are as follows:
Improved HDX performance
Citrix Receiver has been updated to enhance client-side hardware acceleration. This feature improves HDX 3D Pro performance on clients by enabling hardware acceleration. For more information about configuring this feature, refer to the Hardware Decoding section in the User Experience article.
Enhancements to the authorization platform
Citrix Receiver for Windows now integrates functionality that improves how you can verify how clients connect to servers using a specific TLS version, including verification about the specific encryption algorithm, mode, key size and whether SecureICA is enabled. Using this feature, you can also view the current authentication certificate used by the client during an active session. For more information, see the XenApp - XenDesktop article that discusses how cryptography is used.
Improved launch dialog messages
This version improves how Citrix Receiver for Windows uses launch dialogs when informing users about system-related changes and updates. It now provides simple notifications that replace bulky system level notifications when launching a session.
Enhanced diagnostic information collection
This release integrates an improved diagnostic tool you can use to quickly collect system information, and distribute the information by creating a single compressed package that can be easily transferred or uploaded to services such as CIS.
