With this feature, each machine is aligned to the maximum load index before the next machine is powered on. This feature achieves maximum utilization for each machine and cost savings in public clouds. This feature offers more flexibility in managing the load balancing strategies for machines.

You can configure a delivery group to either adopt the load balancing method set at the site level, or to select between vertical or horizontal load balancing methods, thus overriding the site-level setting. For more information, see Load balancing.

Support for creating empty machine catalogs

You can now create a machine catalog without immediate VM creation. With this feature, you can postpone VM creation until back-end hosts are fully prepared or VM provisioning is completed, gaining more flexibility in creating catalogs. For more information, see Create machine catalogs.

Support for changing networks for resources

In Web Studio, you can now change networks for resources associated with host connections. You can’t unassociate networks from resources if the resources are in use. For more information, see Edit networks.

PowerShell logging

In Web Studio, you can now view the PowerShell commands corresponding to your daily UI actions. This feature helps you gain insights into the underlying PowerShell commands for learning purposes. To view the PowerShell logs, go to Logging > PowerShell. For more information, see Configuration logging.

MCS-provisioned machine catalogs

Detect Orphaned Azure resources. With this feature, you can now detect the orphaned resources in your Azure deployment, enabling efficient resource management. After the orphaned resources are identified, you can take further action, bringing in more productivity and cost reduction. For more information, see Detect Orphaned Azure resources in your deployment.

Machine profile support for AWS and GCP VMs. When provisioning AWS or GCP VMs using MCS, you can now select an existing VM as the machine profile, letting VMs inherit settings from the selected VM.

  • For GCP VMs, the inherited settings include Disk Encryption Set ID, Machine size, Storage type, and Zone.

  • For AWS VMs, the inherited settings vary based on the stage:

    • During catalog creation: Machine specification, Machine size, Tenancy type, Security group, and the number of NICs

    • During catalog editing: Machine specification, Machine size, and Security group.

For more information, see Create a machine catalog.

Support for updating various Azure machine properties. You can now update the following property settings when managing Machine Creation Services (MCS)-provisioned Azure machine catalogs:

  • Storage type
  • Dedicated host group
  • Azure Compute Gallery settings
  • Write-back cache (WBC) settings, such as Disk cache size, Memory cache size, and Enable storage cost saving

When you update any of these settings, Web Studio automatically identifies related settings and provides automatic synchronization or prompt messages requesting you to reselect related settings. This capability ensures consistent changes across associated settings, preventing potential configuration errors. For more information, see Edit a catalog.

Support for updating various Azure machine properties using machine profiles. For MCS-provisioned Azure machine catalogs, you can now update a wider range of property settings through machine profiles, which include:

  • Machine size
  • License type
  • Availability Zone
  • Dedicated Host Group ID

After you update the machine profile, Web Studio compares the current settings with the new ones. If differences exist, you’re prompted to confirm which to apply. This design ensures transparent and efficient VM setting updates.

Option to downgrade storage disk to Standard HDD when VMs shut down. A new option, Enable storage cost saving, is now available on the Disk Settings page when you create or update Azure catalogs. The option saves storage costs by downgrading to Standard HDD for the storage disk and the write-back cache disk when the VM shuts down. The VM switches to its original settings on restart. For more information, see Create a Microsoft Azure catalog.

Ability to filter machine sizes based on Encryption at Host property in machine profiles (Azure VMs specific). Once you choose a machine profile with Encryption at Host enabled during Azure machine catalog creation or management, only machine sizes that support this feature are displayed.

Certificate expiry warning support for Hybrid Azure AD joined machine catalogs. Web Studio now provides one-month advance warnings for user certificate expiration on Hybrid Azure AD joined machine catalogs. This enhancement aims to reduce the risk of service interruptions resulting from certificate expiration. To view the details and recommended actions, go to the Machine Catalogs node, select the machine catalog, and then click the Troubleshoot tab.

Option to delete VM records only from the Citrix site database. When catalog and VM deletion fails because of an unreachable hypervisor, you can now opt to delete VM records only from the Citrix site database, leaving the VMs intact on the host. For more information, see Delete a catalog.

A single option to retain VM and system disk during power cycles. Starting an existing VM on Azure is now faster than launching a new one, making it a more efficient choice to retain VMs across power cycles. In response to this change, we’ve combined the options Retain VMs across power cycles and Retain system disk during power cycles into a single option Retain VM and system disk during power cycles. This means that when you select this option to reduce VM restart times by retaining system disks, your VMs are retained as well.

Policy sets. In Web Studio > Policies, you can now group policies together for simplified role-based access using policy sets. You can then assign scopes and delivery groups to your policy sets so that only authorized administrators can manage the policies that apply to their relevant users and machines. For more information, see Policy sets.

User experience improvements. To improve the user experience and make policy management more efficient, we’ve implemented the following improvements to the Policies node:

  • New UI design for the Create Policy and Create Template actions:

    • Expandable folder view for policy settings. On the Select Settings page, all settings appear by category in an expandable tree view, making it easier to find a setting.
    • To select a setting, you simply click a checkbox instead of using the Select button.
    • Legacy settings have been hidden by default so that only the most relevant settings are shown. If legacy settings are needed, select Include legacy settings.
    • An action button has been added next to a Boolean setting, enabling you to change its value directly in the settings list.

    Improvements to create policies

  • New UI design for the Edit Policy action:

    • The navigation menu has been updated to an unordered list. Each item in the list now includes a Save button on its page. With this new design, you can save changes made to an item without having to navigate through all items in the navigation menu. These improvements make policy management more efficient and streamlined.
    • Red dots appear next to the navigation items to indicate setting errors.

    Improvements to edit policies

  • Drag to reprioritize policies. In the priority list, you can now change the priority of a policy by dragging it to a wanted position.

VDA version support on settings page of create/edit policy When configuring settings for a policy, you now have an option to view settings in the following categories:

  • All settings. View all settings applicable to all VDA versions.
  • Current settings only. View settings specific to the current VDA version.
  • Legacy settings only. View settings applicable only to the deprecated VDA versions.

Enhanced search functionality

We’ve revamped the search functionality to include interactions for filters, giving you a better user experience. The following additions are available:

  • Delete saved filter sets: You can now easily delete saved filter sets right within the search menu, without navigating to Manage filter sets.
  • AND/OR operator update: Match all (AND operator) and Match any (OR operator) options are now available in the filters panel, accessible with a single click the filters icon.
  • Streamlined criteria selection: You can now specify multiple criteria directly in the filters panel.
  • Cleaner interface: The filter pinning ability has been removed, reducing UI clutter and making your search experience more intuitive.

Citrix Director

User interface improvements

The Citrix Director user interface is now refreshed with a modern look and feel. The new and improved user interface provides easier navigation and better data representation. The improved experience is intuitive and designed to easily comprehend the data required to monitor and troubleshoot a Citrix session.

Play back live and recorded sessions

Citrix Director now supports playing back recorded and live user sessions that are recorded using the Session Recording service. You can quickly understand the session-related issues encountered by the user from the replay. With this feature, you get ready access to recordings along with session-related metrics within the Director console. It helps corelate the issues discovered in the recordings with the performance metrics. It eliminates the requirement of searching for recordings across multiple session recording servers or looking for third-party apps to view the recordings.

This feature requires the following:

  • VDA and the Session Recording server are on version 2308 or later.
  • Delivery Controller and Director are on version 2311 or later.

Director stores the recordings in a centralized repository and displays them on the Session Selector modal. The Sessions with recordings link displays the recordings of sessions that were active during the last 24 hours or the last 2 days. The recording is played back on a new tab using the Citrix Session Recording playback server.

For more information, see Record sessions.

End-to-end Network Hop view

End-to-end network hop view is the next step towards enhancing troubleshooting workflows in Citrix Director. The User Details > Session Performance > Session Topology section provides a visual representation of the end-to-end network hop view for connected HDX sessions. The in-session path helps understand the components involved in the session path with their metadata, the link between the components, and the applications published on the VDA. The Session Topology helps the data flows and to identify the specific hop that might be bringing in performance issues.

In addition, ICA Latency and ICA RTT measurements are displayed for the session when it is in a connected state. For more information, see End-to-end Network Hop view.

Optimal screen resolution

The recommended optimal screen resolution for viewing Citrix Director is updated to 1440 x 1024. For more information regarding the system requirements of Director, see System Requirements.

MS Teams Optimization

Director displays if Microsoft Teams is optimized. This can be viewed in the User Details page > Session Details panel. This information is available for VDA version 2311 and later. Director displays the status of the Microsoft Teams optimization only if Microsoft Teams is running as a published app or inside a published desktop. This enhancement helps in reducing the time to resolve tickets and assists administrators to surface any critical metrics while troubleshooting. For more information, see Troubleshoot user issues.

Probes Overview enhancements

A summary of the Probe Metrics and the Probe Failure Stages in now available in the Probe > Overview page. The Probe Metrics shows the count of Scheduled, Failed, Skipped, and Successful runs. The graphical representation of the failure stages helps analyze the stages in which most failures have occurred. This information helps to quickly troubleshoot the probe results. For more information, see the Application and Desktop Probing article.

Revamped Session Logon Duration view

The new Session Logon tab in the User Details page has an enhanced visualization of the logon duration phases. The new representation shows the overlapping of the individual logon phases. Also provided is the description of the individual phases and drilldown into GPO and Profile Details subphase measurements. This visualization helps understand and easily troubleshoot issues related to logon duration. For more information, see Diagnose user logon issues.

Dynamic Session Recording

You can now record the current active session using the Session Recording controls from the User Details screen without the need to re-establish the session. This feature enables quicker and effective troubleshooting of session experience-related issues faced by users. This is useful to debug issues that are difficult to reproduce.

For more information about Dynamic Session Recording, see the Session Recording service article.

Machine Creation Services (MCS)

Preview features

Support for hibernation-capable VMs (Preview). In Azure environments, you can create an MCS machine catalog using Web Studio and PowerShell commands that supports hibernation. Using this feature, you can suspend a VM when the session is idle for some time, and then reconnect to the previous state of the VM when a user signs in again. For more information, see Create hibernation-capable VMs (Preview).

Support for Citrix-managed HPE Moonshot plug-in (Preview). Previously, you used HPE-managed Moonshot plug-in (HPE Moonshot Machine Manager) maintained by Hewlett Packard Enterprise (HPE) to perform the power management actions on HPE Moonshot chassis. The plug-in was based on legacy APIs that made MCS infrastructure projects difficult. With this feature, a Citrix-managed HPE Moonshot plug-in (HPE Moonshot) is introduced. With this plug-in, you can create connections to your HPE Moonshot chassis, create catalogs, and power manage machines in the catalog using Web Studio and PowerShell commands. For more information, see:

Support for copying tags from a machine profile source to a VM. With this feature, you can copy tags on NICs, and disks (Identity disk, write back cache disk, and OS disk) that are specified in the machine profile to newly created VMs in an MCS machine catalog. You can specify these tags in any of the machine profile sources (AWS EC2 instance or AWS launch template version). This feature is applicable to persistent and non-persistent machine catalogs and VMs.

For more information, see Copy tags on VMs.

Remove tags when deletinge VM record from Citrix. Previously, Remove-ProvVM and Remove-ProvScheme PowerShell commands with ForgetVM parameter removed the VMs and machine catalogs from the Citrix database. However, the commands didn’t remove the MCS-created tags. You had to individually manage the VMs and machine catalogs that weren’t removed entirely from all the resources.

With this feature, you can use:

  • Remove-ProvVM with ForgetVM parameter to remove VMs and MCS- created tags from a single VM or a list of VMs from a machine catalog.
  • Remove-ProvScheme with ForgetVM parameter to remove a machine catalog from the Citrix database and resources from a machine catalog.

This implementation helps in:

  • Identifying leaked resources
  • Removing the additional cost of maintaining the resources that are not required

This feature is only applicable to persistent VMs. For more information, see Remove tags.

Support for machine profile. When you create a catalog to provision machines using Machine Creation Services (MCS) in AWS, you can now use a machine profile to capture the hardware properties from an EC2 instance (VM) or launch template version and apply them to the provisioned machines. Properties that are captured can include, for example, EBS volume properties, instance type, EBS optimization, and other supported AWS configurations. When editing the catalog, the machine profile of the provisioned machines can be changed by providing a different VM or launch template. For more information, see Create a catalog using a machine profile.

Support for filtering instances. Previously, when you used an AWS EC2 instance as a machine profile input to create an MCS machine catalog, the catalog sometimes would not get created properly or function correctly because of an invalid machine profile input (for example, a machine profile input that has certain property values incompatible with the master image). With this feature, you can list the AWS EC2 instances that can be used as valid machine profile VMs. To do this, use the Get-HypInventoryItem command. For more information, see Filtering VM instances.

Support for instance hibernation. You can now launch AWS instances, use them as desired, and then hibernate them. The hibernation process stores the in-memory state of the instance, along with its private and elastic IP addresses, allowing it to pick up exactly where it left off. For more information on creating VMs that support hibernation, see Instance Hibernation.

Support for capturing diagnostic settings from a machine profile. In Azure environments, MCS now supports capturing of diagnostic settings on VMs and NICs from a machine profile while creating or updating an MCS machine catalog, or updating existing VMs. Therefore, with this implementation, the diagnostic data can be seamlessly transmitted to designated Azure destination endpoints, such as Log Analytics workspaces or Event Hubs, for in-depth analysis and visualization. For more information, see Capture diagnostic settings on VMs and NICs from a machine profile.

Azure support for using spot VMs with MCS. Azure Spot VMs allow you to take advantage of Azure’s unused computing capacity at a significant cost savings. However, due to its eviction policy, Azure Spot VMs are good for only some non-critical applications and desktops.

With this feature, you can create an MCS machine catalog of Azure Spot VMs using a machine profile (VM or template spec). You can update an existing catalog to have Azure Spot VMs as the newly created VMs or switch to have standard Azure VMs. You can also update existing VMs to be Azure Spot VMs. For more information, see Create a catalog using Azure Spot VMs.

Get encryption at host information associated with a machine profile. In Azure environments, with this feature, you can now know whether encryption at host is enabled for a machine profile input (VM or template spec) using PowerShell commands. For more information, see Retrieve encryption at host information from a machine profile.

Use Disk Encryption Set ID (DES ID) of the master image to encrypt all the disks of catalog VMs. In Azure environments, previously, the Disk Encryption Set ID (DES ID) of an MCS machine catalog was derived from a machine profile or custom properties. With this feature, a machine catalog can also derive the DES ID from the master image to encrypt all the disks of the VMS in a catalog.

Support for creating a customer-managed encryption key enabled PVS catalog. In Azure environments, you can now create a PVS catalog enabled with customer-managed encryption key (CMEK) using the Web Studio and PowerShell commands. For more information, see Create a customer-managed encryption key enabled catalog.

MCS creates resource group for creating PVS catalog. While creating a PVS catalog using Web Studio, if you do not select an existing resource group, MCS automatically creates a resource group for creating the catalog. For more information on creating a PVS catalog, see Create Citrix Provisioning catalogs.

Support for backup VM sizes configuration. Public clouds can sometimes run out of capacity for a specific VM size. Also, if you use Azure Spot VMs, then the VMs are evicted at any time based on Azure’s capacity needs. In such a case of insufficient capacity on Azure or a Spot VM power-on failure, MCS now falls back on the backup VM sizes. You can provide a list of backup VM sizes using a custom property BackupVmConfiguration. MCS tries to fall back on the backup VM sizes in the order that is provided by you in the list. In case, MCS fails to fall back on all backup VM sizes provided, you get an error message.

This feature is supported only for a catalog that uses a machine profile and is applicable to both persistent and non-persistent MCS machine catalogs. This feature is currently supported only for Azure environments.

For more information, see Configure backup VM sizes.

Ability to copy tags on all resources. With this feature, in Azure environment, you can now copy tags specified in a machine profile to all the resources such as, multiple NICs and disks (OS disk, Identity disk, and write-back cache disk) of a new VM or an existing VM in a machine catalog.

The machine profile source can be a VM or an ARM template spec. For more information, see Copy tags on all resources.

Support for provisioning catalog VMs with Azure Monitor Agent. Azure Monitor Agent (AMA) collects monitoring data and delivers it to Azure Monitor. With this feature, you can provision MCS machine catalog VMs (persistent and non-persistent) with AMA installed as an extension. This implementation enables monitoring by uniquely identifying the VMs in monitoring data. For more information on AMA, see Azure Monitor Agent overview.

Currently, MCS supports only the machine profile workflow for this feature.

For more information on provisioning machine catalog VMs with AMA enabled, see Provision catalog VMs with Azure Monitor Agent installed.

Managing machine catalogs

MCS support for managing different versions of a machine catalog. With this feature, you can manage the configuration versions of a machine catalog using PowerShell commands. Each configuration change using the Set-ProvScheme results in a new configuration version. You can:

  • See the list of versions
  • Use any previous version to update a machine catalog
  • Manually delete a version if it is not used by a VM
  • Change the number of maximum versions to be retained by a machine catalog

For more information, see Manage versions of a machine catalog.

Support for converting a non-machine profile-based machine catalog to machine profile-based machine catalog in AWS environment. In an AWS environment, you can now use a VM or launch template as a machine profile input to convert a non-machine profile-based machine catalog to machine profile-based machine catalog. New VMs added to the catalog take property values from the machine profile. For more information, see Convert a non-machine profile-based machine catalog to machine profile-based machine catalog.

Repair the identity information of active computer accounts. With this feature, you can reset the identity information of active computer accounts that have identity-related problems. You can choose to reset only the machine password and trust keys, or reset all configuration of the identity disk. This implementation is applicable to both persistent and non-persistent machine catalogs. Currently, the feature is supported only for Azure and VMware virtualization environments. For more information, see Repair the identity information of active computer accounts.

Ability to reset the OS disk of a persistent VM in an MCS created machine catalog in AWS. In AWS environments, you can now use the PowerShell command Reset-ProvVMDisk to reset the OS disk of a persistent VM in an MCS created 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.

For more information on using PowerShell command to reset the OS disk, see Reset OS disk.

Retrieve a list of orphaned resources

You can get a list of orphaned resources that are created by MCS but are no longer tracked by MCS. This is currently applicable to Azure environments. To get the list, you can use PowerShell commands. You can filter using connections. For more information, see Retrieve a list of orphaned resources.

MCS ability to change memory and disk cache size

With this feature, you can now change the memory and disk cache size of the Write-back cache (when MCSIO is enabled) using a PowerShell command without creating a new machine catalog. This implementation helps you to have the optimized cache configuration that is suitable for your business needs. This feature is applicable to:

  • GCP and Microsoft Azure environments, and
  • a non-persistent catalog with MCSIO enabled

For more information, see Change cache configuration on an existing machine catalog.

VMware support for storage migration of VMs

With this feature, in a VMware environment, you can move the disk storage of existing VMs from an old storage to a new storage. During migration, MCS retains VM capabilities such as power management, reset OS disk, and so on. You can also add new VMs to the machine catalog using the new disk storage service. To do this, use the PowerShell command Move-ProvVMDisk. For more information, see Storage migration of VMs.

SCVMM support for machine profile

With this feature, you can now use a machine profile to create and update an MCS machine catalog in System Center Virtual Machine Manager (SCVMM) environments. You can also enable nested virtualization and vTPM. For more information, see Create a catalog with a machine profile.

Repair the user certificates of hybrid Azure AD joined machine identities

With this feature, you can use Powershell command to repair the user certificates of hybrid Azure AD joined machine identities if they corrupt or expire. For more information, see Create Hybrid Azure Active Directory joined catalogs.

You can run the Get-ProvScheme command to get information about the user certificate expiration date of a hybrid Azure AD joined machine catalog.

Solution for SCCM duplicated GUID issue

After creating multiple VMs using MCS, the System Center Configuration Manager (SCCM) displayed only one VM on its console because of duplicated GUIDs.
