Product Documentation

What’s new

A goal of Citrix is to deliver new features and product updates to XenApp and XenDesktop Service customers when they are available. New releases provide more value, so there’s no reason to delay updates. Rolling updates to the service release approximately every three weeks.

This process is transparent to you. Initial updates are applied to Citrix internal sites only, and are then applied to customer environments gradually. Delivering updates incrementally in waves helps ensure product quality and maximize availability.

For details about the service level goal for cloud scale and service availability, see Service Level Goal. To monitor service interruptions and scheduled maintenance, see the Service Health Dashboard.

Virtual Delivery Agents (VDAs): VDAs for Windows machines often release on a different schedule than other components, features, and technologies. Generally, VDAs release at the same time as the on-premises product.

  • For information about new VDA and HDX features, see the What’s new and Known issues articles for the current on-premises XenApp and XenDesktop product.
  • For information about VDA platforms and features that are no longer supported, see Deprecation. The Deprecation article also includes platforms and features that are scheduled to be unsupported in a future release (such as which operating systems support VDA installation).

August 2018

  • Deprecation of TLS versions. To improve the security of the XenApp and XenDesktop Service, Citrix will block any communication over Transport Layer Security (TLS) 1.0 and 1.1, effective December 31, 2018. For details, see Deprecation of TLS versions.
  • Google Cloud Platform virtualization environment. The XenApp and XenDesktop Service supports the ability to manually power cycle XenApp and XenDesktop VMs on the Google Cloud Platform (GCP). For more information, see Google Cloud Platform virtualization environment.

June 2018

  • Azure Resource Manager connections. In the Studio connection creation wizard, the Azure environment selection on the Connection page includes all Azure Clouds that are valid for your Azure subscription. General availability for Azure US Government Cloud and Azure Germany Cloud replaces the preview versions of those two environments in earlier releases.

May 2018

  • Azure Quick Deploy. When your resource location uses Azure Resource Manager machines to deliver applications and desktops, you can now choose a deployment method:

    • Full Configuration: This existing method uses the Studio management console, which guides you through creating a machine catalog and then creating a Delivery Group.
    • Azure Quick Deploy: This new option offers a simpler interface that offers faster deployment of apps and desktops.

    For details, see Azure Quick Deploy.

  • Citrix Health Assistant link. The Machine Details page of an unregistered machine in the Monitoring console now contains a Health Assistant button. Currently, the button links to the Troubleshoot machines article in and to the Knowledge Center article, Citrix Health Assistant - Troubleshoot VDA Registration and Session Launch where you can download the tool. Citrix Health Assistant is a tool to troubleshoot configuration issues in unregistered VDAs. The tool automates a number of health checks to identify possible root causes for common VDA registration, session launch, and time zone redirection configuration issues.

  • Interactive Session drill-down. In the monitoring console, the User Details view > Logon Duration panel now includes information on the Interactive Session stage of the logon process. To provide more granular troubleshooting and remediation of this phase of the logon, Interactive Session now has three sub-phases: Pre-userinit, Userinit, and Shell. In this release, hovering over Interactive Session displays a tooltip showing the sub-phases and a link to the documentation. For a description of the sub-phases and how to improve the performance of each phase, see Diagnose user logon issues.

March 2018

  • Application instance prediction (Preview feature). This is the first monitoring feature based on predictive analytics. Predicting resource usage patterns is important for administrators to organize resources and the required number of licenses on each resource. The Application instance prediction feature indicates the number of hosted application instances that are likely to be launched per Site or Delivery Group over time. Machine learning algorithms based on data models created with existing historical data are used to do the prediction. Tolerance level indicates the prediction quality.

    For more information see Application instance prediction in Director. Submit your feedback regarding the usefulness and usability of this feature in the Citrix Cloud discussion forum.

  • Delivery Groups APIs - Tech Preview

    The Delivery Groups APIs Tech Preview provides a set of REST APIs that you can use to automate the management of Delivery Groups. The complete set of available APIs can be viewed and tried out in the Citrix Cloud APIs documentation at

  • Web Studio authentication

    The service management console on Citrix Cloud now uses a bearer token to authenticate customers. The bearer token is needed to authenticate access to the Delivery Groups REST API.

  • Access Monitor Service data using OData Version 4 API (Preview feature)

    You can create your customized monitoring and reporting dashboards based on the Monitor Service data by using the OData V.4 endpoint. OData V.4 is based on ASP .Net Web API and supports aggregation queries. Use your Citrix Cloud user name and bearer token to access the data with the V4 endpoint. For more information and examples, see Access Monitor Service data using the OData v4 endpoint in Citrix Cloud.

    Share your feedback on the utility of this feature in the Citrix Cloud discussion forum.


  • You can rename, move, and delete application folders. [#STUD-2376]

January 2018

  • RDS license check. Creation of machine catalogs containing Windows Server OS machines now includes an automatic RDS license check. Any RDS license issues found are displayed, so that you can take the appropriate steps to prevent a gap in service. For details, see Create machine catalogs.

  • Access to machine console from Monitor. The Machine Details panel from Monitor now provides access to consoles of machines hosted on the XenServer hypervisor version 7.3. You can now troubleshoot issues in VDAs directly from Monitor. For more information, see Machine Console access in Troubleshoot machines.

December 2017

New and enhanced features

  • Citrix Workspace. Citrix Workspace is now available for new XenApp and XenDesktop Service customers. For more information, see Workspace Configuration.

  • Applications Analytics. You can now analyze and monitor the performance of applications efficiently with the new Application Analytics page available from Monitor > Applications tab. The page provides a consolidated view of the health and usage of all applications published on your Site. It shows metrics such as the number of instances per application, and faults and errors associated with the published applications. This feature requires VDAs Version 7.15 or later.

    For more information, see Application Analytics section in Director.

November 2017

New and enhanced features

  • (Currently not available) Local Host Cache. Local Host Cache enables connection brokering operations to continue when a Cloud Connector in a resource location cannot communicate with Citrix Cloud. For details, see Local Host Cache.
  • Azure Managed Disks. Azure Managed Disks are now used by default for MCS-provisioned VMs in Azure Resource Manager environments. Optionally, you can use conventional storage accounts. For details, see Microsoft Azure Resource Manager virtualization environments.
  • Help desk administrator. When managing service administrators for a Citrix Cloud customer account, you now have a new choice: Help Desk Administrator. A help desk administrator can access the Monitor functions in the service. For details, see Manage.


  • You can now use the service management console wizard to create a Remote PC Access machine catalog. In earlier releases, you had to use a PowerShell cmdlet to create a catalog (as documented in CTX220737). Then, you had to return to the management console to create a Delivery Group. Now, you create the catalog and the Delivery Group sequentially in the management console.
  • MCS-created catalogs can use existing Active Directory machine accounts. [#DNA-24566]
  • When monitoring a deployment, scrolling in a sorted Trends > Sessions table displays accurate results. [DNA-51257]
