* Fixed an issue where the Slack notifier was using a deprecated argument.
* Added the `--docker-image` argument to the **lint** command, which allows determining the docker image to run lint on. Possible options are: `'native:ga'`, `'native:maintenance'`, `'native:dev'`, `'all'`, a specific docker image (from Docker Hub) or, the default `'from-yml'`.
* Fixed an issue in **prepare-content** command where large code lines were broken.

* Added the marketplaces field to all schemas.
