The software development of Checkmk is organized in so-called Werks. A Werk is any change or bug fix that has an influence on the user's experience. Each Werk has a unique ID, one of the levels Trivial Change, Prominent Change or Major Feature and one of the classes Bug Fix, Feature or Security Fix.
Whenever you make an update to a new Checkmk version please make sure that you have understood all incompatible changes. You might have to adapt your configuration.
