 ### Compatibility
-Since the beginning of IntelMQ, the bot's `process` methods use the methods `self.receive_message`, `self.acknowledge_message` and `self.send_message`. Breaking this paradigm and changing to method parameters and return values or generator yields would indicate an API change and thus lead to IntelMQ version 4.0.
-To be decided if this should be done.
