Citrix Virtual Apps and Desktops 7 2308
About the 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 the latest features.
Install or upgrade VDAs in an existing site: If you already 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 can be 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 later) value remains the default functional level and is valid for this release. For more information, seeVDA versions and functional levels.

Configurable Studio inactivity timeout
作为管理员的完全访问,您现在可以configure the inactivity timeout for the Studio console. This setting determines how long administrators can remain inactive before being automatically signed out of the Studio console. The inactivity duration must be set between 10 minutes and 24 hours. For more information, seeSet the inactivity timeout.
Integrated Windows authentication
You can now enable integrated Windows authentication for quick and seamless access to Web Studio. This feature allows your users to access Web Studio with their Windows credentials, using Kerberos or NTLM. For more information, seeManage authentication.
Image refresh option
When selecting master images for machine catalogs, you can now quickly get the most up-to-date master image list using theRefreshoption at the top right corner. Note that Refresh option is not available for AWS catalogs. Also, a Refresh option is available for machine profiles and host groups in Azure catalogs.
Removed support for changing the OS type for Azure catalogs
When changing catalog images, only images with the same OS type as the image in use are shown. With this enhancement, Citrix Virtual Apps and Desktops no longer support changing the OS type for Azure catalogs after catalog creation.
Shared tenants for connections
You can now add tenants and subscriptions that share the Azure Compute Gallery with the subscription of the connection. As a result, when creating or updating catalogs, you can select shared images from those tenants and subscriptions. For more information, seeManage service principals and connections.
Support for organizing machine catalogs, delivery groups, and application groups using folders
You can now create nested folders to organize machine catalogs, delivery groups, and application groups for easy access.
Citrix Director
Probes summary and drilldown
Application and desktop probing automates the process of checking the health of the apps and desktops that are published in a site by test launching them serially using StoreFront. The results of probing are available in Director.
Now, all probe related results are consolidated under theTrends > Probestab with the following information:
TheOverview选项卡支持vides a summary of all the configured probes in a single view. You can filter probes based on Time Period, Probe Type, Endpoint name, Application Name, Desktop Name and Probe Result Type. Probes that match the filter criteria are shown with the following details per probe, application/desktop, and endpoint.
- Completed Runs– the number of probe runs that ran to completion.
- Failed Runs– the number of probe runs that failed.
TheProbe Runs选项卡支持vides the results of the completed probe runs in detail. You can filter the probe runs based on Time Period, Probe Type, Endpoint name, Application Name, Desktop Name and Probe Failure Stage. Clicking theProbe Name,Failed Runs,Application/Desktopname links also takes you to theProbe Runspage with the list of Probe runs matching the filter criteria.
For more information, see theApplication and Desktop Probingarticle.
Citrix Probe Agent support for Citrix Gateway Multi-factor authentication
Citrix Probe Agent for application and desktop probing now supports authentication via Citrix Gateway Multi-factor authentication. This feature is available only for Citrix Gateway that is configured with LDAP and Native OTP using Single Login Schema. The comprehensive probe results available on Director help troubleshoot issues related to the applications, hosting machine, or connections before the users experience them. For more information, see theApplication and Desktop Probing article.
Disable Hypervisor Alerts
You can now disable Hypervisor Alerts fromCitrix Alerts Policy > Site Policy > Hypervisor Health. This helps optimize alerts if your role does not involve infrastructure monitoring. For more information, seeHypervisor Alerts Monitoring.
Trends for Session Experience metrics
Director is introducing a newUser Details > Session Experiencetab with enhanced troubleshooting workflows starting with the ability to correlate real-time metrics in identifying issues within user sessions. Session Experience now contains trends of session metrics like ICARTT, ICA Latency, Frames Per Second, Output Bandwidth Available, and Output Bandwidth Consumed. This feature helps reduce the mean time for resolution by enabling you to correlate multiple performance metrics in a single view. For more information see theUser Issuesarticle.
Machine Creation Services (MCS)
Secure environment for GCP managed traffic
With this feature, you can now allow private Google access to your Google Cloud projects. This implementation enhances security to handle sensitive data. To achieve this, you can do one of the following:
- Allow ingress rule for Cloud Build Service Account in VPC service perimeter
- If you are using a private worker pool, add UsePrivateWorkerPool in CustomProperties.
For more information, seeCreate a secure environment for GCP managed traffic.
Support for machine profile in Citrix Hypervisor
In Citrix Hypervisor, you can now create an MCS machine catalog using a machine profile. The source of the machine profile input is a VM. The machine profile captures the hardware properties from a VM template and applies them to the newly provisioned VMs in the catalog. For more information, seeCreate a machine catalog using a machine profile.
Ability to reset the OS disk of a persistent VM in an MCS created machine catalog in SCVMM
You can now use thePowerShellcommandReset-ProvVMDisk
重置操作系统磁盘的持久MCS - VMcreated machine catalog. The feature automates the process of resetting the OS disk. For example, it helps in resetting the VM to its initial status of a persistent development desktop catalog created using MCS. Currently, this feature is applicable to Azure, Citrix Hypervisor, SCVMM, and VMware virtualization environments. For more information on using thePowerShellcommand to reset the OS disk, seeReset OS disk.
Restrict upload and download of managed disks
In Azure environments, you can use private endpoints to restrict access to disk contents. This implementation helps you to securely access data over a private link. However, as per Azure policy, you cannot upload or download more than five disks or snapshots at the same time with the same disk access object. For more information on using private endpoints to restrict the export and import of managed disks, seeRestrict import/export access for managed disks using Azure Private Link.
With this feature, you can use disk access and private endpoints to lock down your Azure environment, without any risks of failures because of exceeding the limit. MCS runs only up to five concurrent operations. Any excess operations are queued to run when there is more bandwidth.
Support for assigning a specific drive letter to MCS I/O write-back cache disk
Previously, the Windows operating system automatically assigned a drive letter to the MCS I/O write-back cache disk. With this feature, you can now assign a specific drive letter to MCS I/O write-back cache disk. This implementation helps you to avoid conflicts between the drive letter of any applications that you use and the drive letter of the MCS I/O write-back cache disk. This feature is applicable to only the Windows operating system. For more information, seeAssign a specific drive letter to MCS I/O write-back cache disk.
Preserve NIC settings on provisioned VMs
Previously, the NIC settings of the master image were not retained in the provisioned VMs. For example, if you configured the DNS settings on the master image, the provisioned VMs did not retain the configured DNS settings of the master image. With this feature, the provisioned VMs can now retain the NIC settings of the master image. The settings are retained even after a Windows update. The filter driver is automatically installed if you do a fresh installation of VDA version 2308 or later on a Hyper-V deployed machine through the MCS master image installations. However, currently, if you upgrade from an older version of VDA (version less than 2308) and want to install the filter driver, then you must select the checkboxCitrix HyperV Filter Driver
on theAdditional Components
page while upgrading the VDA. For more information, seeInstall additional components. This feature is applicable to:
- Hyper-V VMs (including Azure and SCVMM)
- Persistent and non-persistent MCS machine catalogs
- Non-persistent MCS machine catalogs with MCSIO
- Master image with multiple NICs
Support for sharing images across different Azure tenants
Previously, in Azure environments, you can share images only with shared subscriptions using the Azure Compute Gallery. With this feature, you can now select an image in the Azure Compute Gallery that belongs to a different shared subscription in a different tenant to create and update an MCS catalog. For more information, seeShare images across tenants.
Update properties of individual VMs
You can now update the properties of individual VMs in a persistent MCS machine catalog using a PowerShell command. This implementation helps you to manage individual VMs efficiently without updating the entire machine catalog. Currently, this feature is applicable only to the Azure environment. For more information, seeUpdate properties of individual VMs.
Support for vSAN 8.0
You can now use MCS to provision VMs in the vSAN 8.0 environment.
