Why all these changes? And was it necessary?

Most of these changes are to prepare for Checkmk 2.5. I didn’t have to put all the changes into version 1.2.0 right away. But that would mean having another “breaking” update at the latest with the release of Checkmk version 2.5.
And yes, I think with the changes in Checkmk 2.5, it’s worth the effort.

Cheers
