What’s new in Citrix Virtual Apps and Desktops 7 1811
This article describes information published with an earlier version of Citrix Virtual Apps and Desktops. For information on the current release, see the Citrix Virtual Apps and Desktops documentation.
About this release
This Citrix Virtual Apps and Desktops release includes new versions of the Windows Virtual Delivery Agents (VDAs) and new versions of several core components. You can:
Install or upgrade a Site
Use the ISO for this release to install or upgrade core components and VDAs. Installing or upgrading to the latest version allows you to use all the latest features.
Install or upgrade VDAs in an existing Site
If you have a deployment, and aren’t ready to upgrade your core components, you can still use several of the latest HDX features by installing (or upgrading to) a new VDA. Upgrading only the VDAs is often helpful when you want to test enhancements in a non-production environment.
After upgrading your VDAs to this version (from version 7.9 or later), you do not need to update the machine catalog’s functional level. The 7.9 (or newer) value remains the default functional level, and is valid for this release. For more information, see VDA versions and functional levels.
- If you are building a new site, follow the sequence in Install and configure.
- If you are upgrading a site, see Upgrade a deployment.
Citrix Virtual Apps and Desktops 7 1811
This product release includes the following new, modified, and enhanced features.
New product names and version numbers were introduced in Citrix Virtual Apps and Desktops 7 1808. That information is retained in this article for reference. For more information, see New product names at the end of this article.
Delivery Groups: New Studio interface for creating machine restart schedules
In earlier releases, you used Studio to create a restart schedule for machines in a Delivery Group. To create multiple schedules, you used PowerShell cmdlets. Now, the updated Studio interface enables you to create and manage one or more restart schedules. For details, see Create and manage restart schedules for machines in a Delivery Group.
Citrix Scout: AOT traces on network shares
In earlier releases, Always On Tracking (AOT) traces that were saved to network shares were not included in collected diagnostics. Now, those traces are included. For details, see Citrix Scout.
Machine catalogs: New functional level
A new machine catalog functional level has been added. The default remains 7.9 (or newer). Keep that default, unless all of the VDAs in the catalog are version 1811 or later supported versions. For more information, see VDA versions and functional levels.
Machine Creation Services (MCS) provisioning to AWS dedicated hosts
This release adds support for Machine Creation Services (MCS) provisioning to AWS dedicated hosts. An administrator can create a catalog of machines with host tenancy defined through PowerShell. See AWS host tenancy support.
Support for AWS IAM roles
Citrix Studio supports the ability to configure an AWS Hosting Connection to use IAM roles by entering role_based_auth as the value for the Access Key and Secret Key fields. An IAM Role defining the policy and permissions required by Citrix is required when attaching to AWS hosted Delivery Controllers or Cloud Connectors instances.
Logon Performance - Profile Drilldown
The Logon Duration panel in the User Details pages now includes information on the Profile load phase drill down of the logon process. Profile Drilldown provides useful information about user profiles for the current session that can help administrators troubleshoot high profile load issues. A tool tip with the following user profiles information is displayed:
- Number of files
- Profile size
- Number of large files
A detailed drill down provides information about the individual folders, their size, and the number of files. This feature is available on Delivery Controller version 7 1811 or later and VDAs 1811 or later. For more information, see Diagnose user logon issues.
Microsoft RDS license health
Director now displays the Microsoft RDS (Remote Desktop Services) license status on the Machine Details panel in the Machine Details and the User Details page for Server OS machines. An appropriate message is displayed for the license status. You can hover over the info icon to see further details. For more information, see the Microsoft RDS license health section in Troubleshooting Machines.
Hypervisor alerts monitoring
Director now displays alerts to monitor hypervisor health. Alerts from Citrix Hypervisor and VMware vSphere are supported. Hypervisor alerts help monitor the following states/parameters:
- CPU usage
- Memory usage
- Network usage
- Hypervisor connection unavailable
- Disk usage (vSphere only)
- Host connection or power state (vSphere only)
Hypervisor alerts monitoring is available for Premium licensed Sites. This feature requires Delivery Controller version 7 1811 or later. If you are using an older version of Director with the latest version of the Site, only the hypervisor alert count is displayed. To view the alerts, upgrade Director. For more information, see the Hypervisor alerts monitoring section in Alerts and Notifications.
Key RTOP Data display
Director now displays key RTOP (RealTime Optimization Pack) 2.6 data in the HDX panel of the User Details page. This helps monitor the following status of the RTOP pack for each user:
- Status (optimized, fallback)
- RTC version
- RTME version on user device
- Packet loss metrics
This feature requires Delivery Controller(s) 7 1811 or later, and VDA 1808 or later.
Application Probing access through Citrix Gateway
You can now use Director’s Application probing feature to probe Citrix Virtual Apps from anywhere. You can use this flexibility to run the Citrix Application Probe Agent on end point machines that are hosted in a different network. You can access the Site you want to probe through the Citrix Gateway. To do this, while configuring the Citrix Application Probe Agent, type the Citrix Gateway URL in the StoreFront URL field. Citrix Gateway automatically routes the request to the corresponding Site StoreFront URL. This feature is available for Citrix Gateway version 12.1 or later, and Delivery Controller(s) 1811 or later. For more information about Application probing setup, see Application probing.
Virtual Delivery Agents (VDAs) 1811
Version 1811 of the VDA for Windows Server OS and the VDA for Windows Desktop OS includes the following enhancements (in addition to the VDA installation and upgrade items listed above):
Graphics status indicator
The Graphics status indicator policy has been updated to replace the display lossless indicator policy.
This setting configures the graphics status 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 Graphics status policy is disabled. It replaces the Display lossless indicator policy of earlier releases, which was enabled by default.
For more information, see Graphics status indicator.
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.
This setting is off 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.
Client drive mapping performance improvements
Client drive mapping now supports the transfer of data from the host to 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:
0x01 - disables
0 or delete- enables
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 feature is supported only on Citrix Workspace app 1811 for Windows or later.
HDX adaptive throughput changes the way that output buffers are set by moving this mechanism from the client to the VDA, and no manual configuration is necessary. This new behavior requires both VDA version 1811 or later and Citrix Workspace app 1811 for Windows or later. It is not available in deployments with older versions of the VDA or of the client.
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 will be used for DPI scaling or DPI matching. After applying a virtual monitor layout, resize or reconnect the session.
This configuration applies to all subsequent applicable connections from this client, only to full screen single monitor desktop sessions, and does not affect any published applications.
Citrix Licensing 11.15
Federated Authentication Service logon evidence support
The Federated Authentication Service (FAS) is now able to receive logon evidence passed to it from Citrix Gateway and StoreFront. The evidence can be validated to ensure that it was issued by a trusted Identity Provider (IdP). A new FAS Assertion SDK is provided to support this feature. For more information about the logon evidence feature, see Citrix Federated Authentication Service Logon Evidence Overview.

- In-product content might still contain former names. For example, you might see instances of earlier names in console text, messages, and directory/file names.
- It is possible that some items (such as commands and MSIs) might continue to retain their former names to prevent breaking existing customer scripts.
- Related product documentation and other resources (such as videos and blog posts) that are linked from this product’s documentation might still contain former names.
- For Citrix Hypervisor: The new name will be used on the Citrix website and in informational product materials from September 2018. You will also see the new name in the administrator consoles of some Citrix products, such as Citrix Virtual Apps and Desktops. The XenServer product release and technical documentation materials will continue to use XenServer 7.x until early 2019.
Your patience during this transition is appreciated. For more detail about our new names, see https://www.citrix.com/about/citrix-product-guide/.
New product and component version numbers
In this release, product and component version numbers are displayed in the format: 7 YYMM.c.m.b.
- YYMM = Year and month when the product or component released. For example, a release in September 2018 appears as 1809.
- c = Citrix Cloud release number for the month.
- m = Maintenance version (if applicable).
- b = Build number. This field is shown only on the About page of the product, and in the OS’s feature for removing or changing programs.
For example, Citrix Virtual Apps and Desktops 7 1809.1.0 indicates that the product released in September 2018, is associated with Citrix Cloud release 1 in that month, and is not a maintenance version. Some displays show only the version’s year and month: for example Citrix Virtual Apps and Desktops 7 1809.
In earlier releases of this product (XenApp and XenDesktop 7.18 and earlier), version numbers were displayed in the format: 7.version, where the version value incremented by one for each release. For example, the release following 7.17 was 7.18. Those earlier releases will not be updated with the new numbering format.
