Camunda Website vs Camunda Modeler

Hello Everyone,
Could you possibly help me with the following issue?
Although some elements of BPMN2.0 being mentioned in Camunda website “https://docs.camunda.org/manual/7.5/reference/bpmn20/” are not supported by Camunda engine, they are included in Camunda modeler. I wonder which one is up to date. Camunda website or Camunda modeler?
Thanks in advance!

The elements mentioned here are supported by the engine i.e. they’re executable. all elements that the engine can execute can be created in the modeler.

The modeler also might have some additional elements (e.g. Complex Gateway) which is useful for modeling documentation but not for executable models.
