Hi @kku,
the Camunda Modeler starting with Version 4.0.0 creates DMN diagrams using the DMN 1.3 standard.
If you don’t need DMN in your Camunda BPM Patform 7.10, you can use the latest Modeler.
Otherwise, to create DMN diagrams that you can run in your current decision engine, you need to download a Modeler with version 3.7.0 or less.
BPMN Diagrams are stable, there are no changes in the specification.
You can find the installation files here: https://downloads.camunda.cloud/release/camunda-modeler/
Hope this helps, Ingo
