The software development of the Checkmk Appliance is organized in so called Werks. A Werk is any change or bug fix that has 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 incompatible Change.
Whenever you make an update to a new Checkmk version please make sure that you have understood all incompatible changes.
