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.


    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.
