What’s new in App Layering 4.12

Release date: July 17, 2018

This release includes the following features and improvements.

  • Support for Windows 10, version 1803: Support for Windows 10, version 1803 is now available.

  • App Layering and Citrix UPM profile streaming: App Layering handling of User Profile Management (UPM) and profile streaming have been improved.

  • Performance improvements when packaging App layers using VMware: The connector cache for VMware connector configurations now allows the appliance to reuse its packaging disks when adding new versions to layers. This can significantly reduce the time it takes to add a new version to a layer. Please set the packaging cache size in your vSphere connector configurations.

  • Packaging cache size for all connector configurations: The Packaging cache size for all connector configurations now defaults to an appropriate starting size for your hypervisor. The Hit rate, indicates how well the cache is working, so you can adjust the cache size to improve layering performance. For details, click here.

Labs features in this release

Labs features are previews of potential functionality for future releases. While a feature is in Labs, you should not use it in production. There is no guarantee that Labs feature will remain in the product, nor that the feature will work as originally designed if and when they are released. The Labs features available in this release include the following:

  • Full User Layer: User layers let you persist user profile settings, data, and user-installed applications in non-persistent VDI environments. This feature is supported in Windows 7 64-bit and Windows 10 64-bit environments.

  • App layers can be assigned as Elastic layers to 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 will work on a different OS layer. If there are issues with the layer on a different OS, then disable this feature and only use the OS that you used to create the App layer.

To use a Labs feature, you need to enable the feature first.
