What’s new in 7 1808
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.
Important notice about Citrix Virtual Apps and Desktops 7 1808.2
Shortly after its initial posting, the Virtual Apps and Desktops 7 1808 ISO and standalone VDA packages were replaced with a newer version that contains a bug fix for Studio. The newer version contains 1808_2 in the ISO name, and 1808.2 in the standalone VDA package name.
If you downloaded an 1808 version before September 4, 2018, check the version.
If you have not used that version to install or upgrade components
Check the name of the download file.
- If the name ends with 1808_2.iso (or 1808.2.exe for standalone VDAs), you can ignore the remainder of this notice.
- If the name does not contain _2 or .2, discard those files and download the latest version from the Citrix website.
If you already used the download to install or upgrade components
Check the version number in your Windows Programs and Features display.
- If the version number contains 1808.2, you can ignore the remainder of this notice.
If the version number contains 1808.1, use the guidance in CTX237835 to install or upgrade the Delivery Controller, Studio, and Director, and your VDAs, to version 1808.2.
Upgrade all of those components to the 1808.2 version, regardless of whether or not you encountered issues with the original 1808 software. Version 1808.2 contains a bug fix for only Studio. Other components did not change between 1808.1 and 1808.2, except for version numbering. However, upgrading all of your components from 1808.1 to 1808.2 will ensure consistency for support.
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 all 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 default (7.9 (or newer …)) remains the current functional level. For 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 Files for Windows allows you to access your Content Collaboration files directly through a mapped drive, providing a native Windows Explorer experience.
- Citrix Hypervisor: The technology from XenServer for virtualization infrastructure, based on the XenProject hypervisor, is now Citrix Hypervisor.
Here’s a quick recap:
|Citrix Virtual Apps and Desktops||XenApp and XenDesktop|
|Citrix Workspace app||Incorporates Citrix Receiver and extensive enhancements|
|Citrix SD-WAN||NetScaler SD-WAN|
|Citrix Secure Web Gateway||NetScaler Secure Web Gateway|
|Citrix Gateway||NetScaler Unified Gateway|
|Citrix Content Collaboration||ShareFile|
|Citrix Files for Windows||ShareFile Desktop App, ShareFile Sync, ShareFile Drive Mapper|
|Citrix Provisioning||Citrix Provisioning Services|
Implementing this transition in our products and their documentation is an ongoing process.
- 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.
Install VDAs: More options that affect what is installed
In earlier releases, the Environment page of the VDA installer indicated only whether or not the machine would be used as a master image. Now, you can indicate which tool you’ll use to provision VMs, if any. Your choices are:
- This machine is a master image to be used with Citrix Machine Creation Services to provision VMs. (Server or desktop)
- This machine is a master image to be used with Citrix Provisioning Services or a third-party provisioning tool (such as Microsoft SCCCM) to provision VMs. (Server or desktop)
- This machine is to be used for brokered connections. (Server only)
- This machine is to be used in a Remote PC Access deployment. (Desktop only)
Your selection affects which Citrix provisioning software is installed. That selection also affects the default values of items on the Additional Components page.
For details, see Install VDAs.
Install and upgrade VDAs: Change in additional component defaults
In earlier releases, when you selected Enable connections to a server machine on the Environment page for a server OS catalog, the Citrix User Profile Manager, Citrix User Profile Manager WMI Plugin, and Citrix Machine Identity Service components were installed by default, even though they did not appear on the Additional Components page in the wizard.
Now, when you selected Enable connections to a server machine on the Environment page for a server OS catalog, the Citrix User Profile Manager and Citrix User Profile Manager WMI Plugin components appear on the Additional Components page. They are not selected by default.
Install and upgrade VDAs: Removal of option to install Machine Identity Service
The Machine Identity Service no longer appears on the Additional Components page. If you select the MCS master image option on the Environment page, the Machine Identity Service is installed automatically. It is not installed if you select any other option on the Environment page. (Although you can prevent (exclude) its automatic installation in a command-line installation, keep in mind that MCS does not work correctly without the Machine Identity Service.)
Install and upgrade VDAs: New command-line option to install additional components
When installing or upgrading a VDA using the command line, you can now use the
/enableadditional option to include an additional component in the installation. For details, see Command line options for installing a VDA.
Install and upgrade VDAs: New option to install Citrix Files for Windows feature
When installing or upgrading a VDA, you can now indicate on the Additional Components page whether to install Citrix Files for Windows (formerly ShareFile). This choice allows users to connect to their Citrix Files account and interface with Citrix Files through a mapped drive in the Windows file system, without performing a full sync of their content. By default, this option is disabled. For information about Citrix Files, see the ShareFile documentation. For installation information, see Install VDAs.
Install and upgrade VDAs: Citrix Workspace app not installed by default
In earlier releases, Citrix Receiver for Windows was installed or upgraded by default when you installed or upgraded a VDA. Now, Citrix Workspace app for Windows is not installed by default when using the full product or VDAWorkstationSetup.exe installer. In a command-line installation, if you omit the
/components option, only the VDA is installed (not the Citrix Workspace app for Windows). To install the Citrix Workspace app with the VDA, select the check box on the Core Components page in the graphical installer, or specify
/components vda plugins on the command line.
Install and upgrade VDAs: Install MCSIO write caching driver and MCSIO default
In earlier releases, the MCSIO write caching driver was installed automatically when you installed a VDA. This driver was used by Machine Creation Services for configuring cache for temporary data (known as MCSIO). Now, when you indicate on the Environment page that you will be using MCS, the Features page contains an entry to enable installation of the MCSIO write caching driver. For details about this option, see Install VDAs.
MCSIO is now disabled by default: the driver installation check box is cleared by default, as are the memory allocation and disk cache size check boxes in the catalog creation wizard. For more information, see Storage shared by hypervisors and Configure cache for temporary data.
Applications: Limit per machine
You can now limit the number of application instances per machine. This limit applies to all machines in the Site. This limit is an addition to the existing application limit for all users in the Delivery Group and the limit per user. This capability is available only through PowerShell, not in Studio. For details, see Configure application limits.
Desktops: Maximum instances per Site
You can now limit how many concurrent instances of a desktop are allowed in a Site. This feature helps service providers control the number of workloads in the Site. This capability is available only through PowerShell, not in Studio. For details, see Create Delivery Groups > Step 6. Desktops.
Windows Server 2019
Upgrading Insider Preview builds of this OS is not supported.
Citrix Scout: Saving AOT traces
In earlier releases, Always On Tracking (AOT) traces were saved to memory. Now, AOT traces are saved to a local disk by default. For details, see Citrix Scout.
Citrix Smart Scale deprecated
Citrix Smart Scale is deprecated in on-premises deployments as of this release. For information about what this means, see Deprecated. As an alternative to Citrix Smart Scale, use the Studio power management feature. For details, see Power manage machines in a Delivery Group.
Machine historical data available using OData API
The following historical data containing machine analytics is now available through the OData API. This data is collected on an hourly basis and rolled up for the day.
- Number of powered on machines (for power managed machines)
- Number of registered machines
- Number of machines in maintenance mode
- Total number of machines
The data is aggregated for the time period during which the Monitoring Service is running. For more information on the usage of the OData API and examples, see Citrix Monitor Service 7 1808. The database schema is available at Monitor Service Schema.
Citrix NetScaler Insight Center has reached its End of Maintenance date as of 15th May 2018. See the Citrix Product Matrix. Integrate Director with Citrix NetScaler MAS for network analysis. To migrate your NetScaler Insight Center to NetScaler MAS, see Migrate from NetScaler Insight Center to NetScaler MAS. For instructions to integrate with MAS, see Configure network analysis.
Export of Filters data
You can now export real-time monitoring data in the Filters tab to CSV format files. The export feature is available from the Machines, Sessions, Connections, and Application Instances Filters pages. You can select a predefined custom filter or select suitable filter criteria, choose required columns in the table, and export the data. Data of up to 100,000 records can be exported. The exported CSV files give a comprehensive view of the real-time data, and help ease analysis of large data sets. This feature is available on Delivery Controller version 7 1808 or later and VDAs 1808 or later. For more information, see Filter data to troubleshoot failures.
Logon Performance - Interactive session drill-down
The Logon Duration panel in the User and Session Details view includes information on the Interactive Session phase of the logon process. The time taken for each of the three subphases (Pre-userinit, Userinit, and Shell) is displayed in the Interactive Session bar as a tooltip. This provides more granular troubleshooting and remediation of this phase of the logon. The cumulative time delay between the subphases and a link to the documentation is also provided. This feature is available on Delivery Controller version 7 1808 or later and VDAs 1808 or later. The Interactive Session drilldown bar shows the time duration for the current session only. For more information, see Diagnose user logon issues.
Logon Performance - GPO drill-down
The Logon Duration panel in the User and Session details view contains the GPO (Group Policy Objects) duration. This is the total time taken to apply the GPOs on the virtual machine during the logon process. Now, you can see the drill-down of each policy applied as per CSEs (Clients-Side Extension) as a tool tip in the GPO bar. For each policy application, the drill-down displays the status and the time taken. This additional information eases troubleshooting and remediation of issues involving high GPO duration. The time durations in the drilldown represent the CSE processing time only and do not add up to the total GPO time. This feature is available on Delivery Controller version 7 1808 or later and VDAs 1808 or later. For more information, see Diagnose user logon issues.
Virtual Delivery Agents (VDAs) 1808
Version 1808 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):
Better network throughput over high latency connections
We raised the default number of ICA output buffers that are used to send and receive data from 44 (64 Kbytes) to 100 (~145 Kbytes). This change delivers improved throughput performance even on high latency connections. This enhancement applies to only Citrix Workspace app 1808 for Windows or higher. For more details, see CTX125027.
Client drive mapping support for large file transfers
Client drive mapping now supports transfers of files larger than 4 Gbytes. Citrix Workspace app for Windows minimum version 1808 is required.
Chrome enhancement to browser content redirection
Browser content redirection now supports the Chrome browser in addition to the previously supported Internet Explorer browser. Browser content redirection redirects the contents of a web browser to a client device, and creates a corresponding browser embedded within the Citrix Workspace apps. This feature offloads network usage, page processing, and graphics rendering to the endpoint. Doing so improves the user experience when browsing demanding webpages, especially webpages that incorporate HTML5 or WebRTC video. This enhancement applies to only Citrix Workspace app 1809 for Windows or higher and requires the browser content redirection extension from the Chrome Web Store. For more information, see Browser content redirection.
Redirection of encrypted hardware USB storage devices
We now support generic USB redirection of encrypted hardware USB storage devices into VDA for Server OS sessions, as well as the previously supported VDA for Desktop OS sessions. After the device is redirected, none of its drives appear on the local client. If unlocking the drive is required, perform that in the session. Ensure that you install Windows update KB4074590 installed on the VDA before using this new feature.
PDF printer support
Printer support for PDFs has been added to users of Citrix Workspace app for Windows.
NVENC video encoding support on Server OS VDAs
The XenApp and XenDesktop 7.17 release introduced Desktop VDA support for selective H.264/H.265 encoding with NVIDIA NVENC GPUs. In this release, the similar capabilities have now been extended to Server OS VDAs equipped with NVIDIA NVENC GPUs.
Support for opening files in Citrix Workspace and editing in a published app
Citrix Workspace app has full integration of Citrix Content Collaboration (formerly ShareFile). After you enable this integration, all your data is accessible within Citrix Workspace app and can be opened and edited in a published application. Users now have access to the tools and data they need regardless of whether they are on their local machine or using the Workspace web experience.
To enable support for opening files in Citrix Workspace, choose the Citrix Files for Windows option on the Additional Components configuration page on the VDAs that provide the published apps. Citrix Files for Windows allows you to access your Content Collaboration files directly through a mapped drive, providing a native Windows Explorer experience. Also configure file type association in Studio. After you configure Citrix Files and file type association on the VDA, users can edit their files in both the desktop and web. For more information, see Open files in Citrix Virtual apps and “Citrix Files for Windows” in Install VDAs.
