+been removed. This means that support for Windows and macOS or the Docker Machine usage is removed from 2.x.
 We're in the process of evaluating whether to add such support to the 2.x stream again, or to adopt
 different solutions. In such a case we'd probably release a 1.x version, which would still support such components.
