 A Zeebe worker to evaluate DMN decisions (i.e. business rule tasks). It uses the [Camunda DMN engine](https://docs.camunda.org/manual/7.12/reference/dmn11/) including the [FEEL-Scala engine](https://github.com/camunda/feel-scala) to evaluate DMN decisions. The DMN files are read from a local directory.
 
+> **Warning**
+> This community extension is deprecated. You should evaluate DMN decisions directly in Camunda 8 using a [business rule task](https://docs.camunda.io/docs/next/components/modeler/bpmn/business-rule-tasks/).
