[DiCanio]

Hi @enajski,
first of all thanks for your contribution and apologies for the rather delayed response.

This PR is good to be merged. However, before doing so I would request you rebasing your branch onto the develop branch. The PR target has already been adjusted.

Some additional information on why we are doing this:
The master branch is effectively our release branch. All other work during releases should happen on the develop branch. Once we got changes that justify releasing a new version they get merged from develop into master, followed by the release itself. This allows us to more easily create and work on potential bugfix branches.
Not communicating that is a shortcoming on our site and gets addressed as soon as possible.

[enajski]

hey @DiCanio my branch should be up to date with upstream develop
