The updated VDA standalone package adds:

  • Support for Windows 10 Enterprise Edition, in the Standard VDA for Windows Desktop OS.

Universal Print Server

The updated Universal Print Server package adds:

  • Support for Windows Server 2012 R2.

HDX technologies

The following new and enhanced HDX technologies features are included in the Feature Pack 3 VDA and managed using the updated Group Policy Management package:

  • Enhancements to Thinwire Compatibility Mode. This mode uses an updated encoder that improves the display performance of simple graphical interfaces, for example in MS Excel and MS Word, without requiring the use of a resource-intensive video codec. For more information, see Thinwire Compatibility Mode.
  • Support for signature devices and drawing tablets. Administrators can set a policy to enable devices for client-side polling and set optimization modes as part of that policy. This means that users can work effectively in wide area networks with devices such as Wacom signature pads and tablets within XenApp and XenDesktop sessions. For more information, see USB devices policy settings.
  • Video fallback prevention policy. Enables administrators to have more control over server-side and client-side fetching and rendering of multimedia content. For example, if a user's device cannot play a video locally, a new setting allows the administrator to control whether the video is automatically rendered on the server, or prevented and a message displayed to the user. For more information, see Multimedia policy settings and Flash Redirection policy settings
  • Minimum version checking for Flash redirection. For client devices accessing VDAs using Receiver for Windows and Receiver for Linux. This gives administrators greater control over specifying minimum versions required for Flash redirection. For more information on how to specify minimum versions, see Flash Redirection
  • Smart card virtual channel improvements. Includes support for smart card reader plug-and-play with Receiver for Windows 4.3, virtual smart cards (Microsoft Windows Trusted Platform Module-based virtual smart cards), and performance improvements. For more information on deploying smart cards, see Smart cards, and Virtual Smart Card Overview in the Microsoft Windows TechCenter.
  • Framehawk virtual display channel integration with the VDA. The Framehawk virtual display channel is integrated into the standalone VDA package. With Framehawk integrated into HDX technology, Citrix provides a smooth and intuitive user experience in conditions where remote workspace users previously experienced poor interactivity, such as on wireless connections with high packet loss or congestion. For more information, see the HDX Framehawk virtual channel administrator guide.
  • Full-screen app support for HDX 3D Pro VDI. The Virtual Delivery Agent (VDA) for HDX 3D Pro supports full-screen apps including 3D and gaming apps within single monitor ICA sessions. 
  • Custom hotkey configuration for lossless compression. With HDX 3D Pro, the administrator can configure a registry setting to set a custom keyboard shortcut to override the default (ALT+SHIFT+1). Users can instantly switch between lossy and visually lossless compression, or between lossy and lossless compression using a custom hotkey. For more information, see GPU acceleration for Windows Desktop OS.
  • Call Home. In this version of Call Home, administrators can run a PowerShell cmdlet (Start-TelemetryUpload) to extract VDA diagnostic information. You can use the cmdlet to either create a local ZIP file, which you can email to your support representative, or you can use credential information combined with a Support Service Request (SR) number to automatically upload the information to Citrix Insights Services. This enables administrators and support representatives to identify and troubleshoot VDA-related issues. The PowerShell cmdlet is supplied with the VDA installer in FP3. 
  • Updated Policy templates. This feature pack delivers new policy templates for High Server Scalability and Optimized for WAN, and replaces the High Definition User Experience template with the Very High Definition template. For more information, see Policy templates.
  • 32-bit cursor support. Delivers an improved user experience in 3D applications which rely on custom cursors.

  • Desktop Composition Redirection (DCR). DCR is disabled by default.

For information, see HDX RealTime Optimization Pack 1.7 for Microsoft Lync.

XenApp 7.6 and XenDesktop 7.6

This product release includes the following new and enhanced features.

Session prelaunch and session linger

The session prelaunch and session linger features help users quickly access applications by starting sessions before they are requested (session prelaunch) and keeping application sessions active after a user closes all applications (session linger). These features are supported for Server OS machines only.

By default, session prelaunch and session linger are not used. A session starts (launches) when a user starts an application and remains active until the last open application in the session closes. You can enable the features for all users in a Delivery Group or only for specified users.

There are several ways to specify how long an unused session remains active if the user does not start an application: a configured timeout and two server load thresholds. You can configure all of them; the event that occurs first will cause the unused session to end.

For more information, see Configure session prelaunch and session linger.

Support for unauthenticated (anonymous) users

When creating or editing Delivery Groups containing Server OS machines, you can now allow users to access applications and desktops without presenting credentials to StoreFront or Citrix Receiver. For example, when users access applications through kiosks, the application may require credentials, but the Citrix access portal and tools do not.

When you configure the Delivery Group, you can grant access to authenticated users, unauthenticated users, or both. When you grant access to unauthenticated (anonymous) users, you must provide an unauthenticated StoreFront store.

For more information, see Users.

Connection leasing

To ensure that the Site database is always available, Citrix recommends starting with a fault-tolerant SQL Server deployment by following high availability best practices from Microsoft. However, network issues and interruptions may prevent Delivery Controllers from accessing the database, resulting in users not being able to connect to their applications or desktop.

The connection leasing feature supplements the SQL Server high availability best practices by enabling users to connect and reconnect to their most recently used applications and desktops, even when the Site database is not available.

Although users may have a large number of published resources available, they often use only a few of them regularly. When you enable connection leasing, each Controller caches user connections to those recently used applications and desktops during normal operations (when the database is available). If the database becomes unavailable, the Controller enters leased connection mode and "replays" the cached operations when a user attempts to connect or reconnect to a recently used application or desktop from StoreFront.

For more information, see Connection leasing.

Application folders

You can organize applications in folders, which makes it easier to administer large numbers of applications in Studio.

By default, applications in a Delivery Group appear in a single folder. From the Delivery Group display in Studio, you can create additional folders and move applications into them. Moving, nesting, and renaming folders are easy drag-and-drop operations; you can also use Actions menu items. Additionally, you can specify folder destinations and create new folders when you add applications to a Delivery Group.

For more information, see Manage application folders.

XenApp 6.5 migration

The XenApp 6.5 migration process helps you more efficiently and quickly transition from a XenApp 6.5 farm to a Site running XenApp 7.6 (or a later supported release). This is helpful in deployments that contain large numbers of applications and Citrix group policies, lowering the risk of inadvertently introducing errors when manually moving applications and Citrix group policies to the new XenApp Site.

After you install the XenApp 7.6 core components and create a Site, the migration process follows this sequence:
  • Run the XenApp 7.6 installer on each XenApp 6.5 worker, which automatically upgrades it to a new Virtual Delivery Agent for Windows Server OS for use in the new Site.
  • Run PowerShell export cmdlets on a XenApp 6.5 controller, which exports application and Citrix policy settings to XML files.
  • Edit the XML files, if desired, to refine what you want to import to the new Site. By tailoring the files, you can import policy and application settings into your XenApp 7.6 Site in stages: some now and others later.
  • Run PowerShell import cmdlets on the new XenApp 7.6 Controller, which import settings from the XML files to the new XenApp Site.
  • Reconfigure the new Site as needed, and then test it.

For more information, see Migrate XenApp 6.x.

Citrix Customer Experience Improvement Program

The Citrix Customer Experience Improvement Program (CEIP) gives you the opportunity to contribute to the design and development of Citrix products. When you enroll in the program, Citrix collects anonymous information about your deployment, which is used to improve product quality, reliability, and performance.

It's easy to enroll in the program after you create or upgrade a Site. You can also opt in or out of the program at any time by selecting Configuration in the Studio navigation pane and following the instructions.

For more information, see About the Citrix Customer Experience Improvement Program.

Enhanced connection throttling settings

To improve performance, you can now specify the maximum number of simultaneous actions, simultaneous Personal Storage inventory updates, and actions per minute that can occur on a host connection.

For more information, see Edit a connection.

Enhanced reporting in Studio

Studio displays more detailed status and error reporting when updating PvD images, and displays comprehensive licensing alerts when you are in the licensing node.

SSL/TLS

You can enable Secure Sockets Layer (SSL/TLS) connections between users and VDAs by configuring SSL/TLS on the machines where the VDAs are installed and in the Delivery Groups that contain the VDAs.

For more information, see SSL.

Virtual IP and virtual loopback

For published applications, you can enable and use the Microsoft virtual IP feature in machines running Windows Server 2008 R2 and Windows Server 2012 R2. Additionally, you can add new Citrix policy settings to manage virtual loopback. A preferred loopback option is also available.

For more information, see Virtual IP and virtual loopback.

Client and session clipboard write

You can restrict or enable sharing of data from the host clipboard to the client or from the client clipboard to the user session. In each case, when sharing is restricted, you can specify data formats that can be shared.

For more information, see ICA policy settings.

Remote PC Access

You can now prevent a local user from disconnecting a remote session without the permission of the remote user.

When disconnecting a remote session, moving the mouse or pressing a keyboard key wakes the local monitor. (In previous releases, pressing CTRL+ALT+DEL twice presented the logon screen.)

Icon locations are now preserved when connecting from a lower resolution device and then returning to a larger resolution device.

Generic USB Redirection

This release provides support for Generic USB Redirection for specialty USB devices for which there is no optimized virtual channel. This functionality redirects arbitrary USB devices from client machines to virtual desktops; with this feature, end users have the ability to interact with a wide selection of generic USB devices in the desktop session as if the devices were physically attached.

With Generic USB Redirection:

  • users do not need to install device drivers on the user device
  • USB client drivers are installed on the VDA machine

This feature requires Windows Server 2012 R2, and functions with existing Windows Receiver versions for published desktop sessions hosted on RDS hosts in single-hop scenarios. Using this feature, USB client drivers are installed on the host, so these drivers must be compatible with RDSH for Windows 2012 R2 platforms.

Citrix Director 7.6.100

Director 7.6.100 includes the following new and enhanced features. For download, installation, and upgrade information, see http://support.citrix.com/article/CTX200330.
