Citrix App Layering

What’s new in App Layering 1910

  • We support the following new versions of hypervisor, provisioning, and connection broker software:
    • Citrix Virtual Apps and Desktops version 7 1909
    • Citrix Provisioning version 1909
    • Nutanix Acropolis Hypervisor (AHV) version 5.11
    • VMware Horizon View 7.9
  • On the Hyper-V platform, you can package layers and publish images using Offload Compositing to dramatically improve performance and compatibility. Gen2 VMs and VHDX disk format are now supported.

  • The App Layering Agent has been updated to support the new Offload Compositing feature. If you use the agent in your deployment, we strongly recommend that you install the agent update on any servers where it is installed.

  • Windows Search index performance is improved when using full User Layers.

  • For administrators publishing layered images, this version adds validation and warnings to give guidance on what disk size to use based on selected app layers.

Labs features in this release

Labs features are previews of potential functionality for future releases. While a feature is in Labs, do not use it in production. There is no guarantee that a Labs feature will become part of the product, nor that the feature will work as originally designed if and when it is released.

The Labs features available in this release include the following:

  • App layers can be assigned as elastic layers on layered images that use a different OS layer: Until now, Elastic layer assignments required that the app layer assigned use the same OS layer that was used to create the App layer. Now you can try assigning an app layer as an Elastic layer on a layered image that uses a different OS layer.

    Important:

    There is no guarantee that an App layer can work on a different OS layer than the one used to create it. If there are issues, you can disable this feature and allow the app layer to be used only with the OS that you used to create the layer.

To use a Labs feature, enable it first.
