Since the introduction of the server-side calls API in Checkmk 2.3, the values of rules of Active checks and Special agents rulesets must be dictionaries. Rules with other value types (left over from old versions or custom plug-ins) have been silently ignored when the configuration was loaded.
cmk-update-config now deletes such rules from your Setup configuration for good and logs every deleted rule. Since these rules never had any effect, your monitoring does not change.
