Hi @CFriedrich,
on our last conference, we said, that the next new feature will be the implementation of the variable support. And we will keep our word. As the support for the Web-API has been removed with the upcoming Checkmk version, we had to cover that problem first.
All other changes are more or less side effects of the transition to the Rest-API, or has been part of an initial training to get two new colleagues into the topic/plugin.
The support of variables is not off the table and still will be the next new feature!
