[//]: # (werk v2) # Ruleset API: Remove unused evaluation type specification key | value ---------- | --- date | 2024-04-04T10:58:02+00:00 version | 2.3.0b5 class | fix edition | cre component | checks level | 1 compatible | no This change is only relevant for plugin developers. Some rule specs allow the configuration of the `eval_type` to specify how the rules are meant to be evaluated in respect to each other. However, this configuration is not considered in some cases, instead Checkmk uses a predetermined evaluation type. For the affected rule specs this option was removed: * AgentConfig * NotificationParameters * DiscoveryParameters
