-There is no explicit "unack" command in Stomp. Once the client receives the message it cannot be marked as "unconsumed" and sent to another subscriber (or redelivered to the same subscriber again). It's up to your application (or Stomp client) to handle failed processing of received messages and implement "message redelivery".
+Since ActiveMQ 5.6.0
+--------------------
+
+Since version 5.6.0 ActiveMQ supports Stomp 1.1, which added an UNACK frame. This can be used to tell the server that the client could not consume the message.
+
+If ActiveMQ receives a NACK frame, then by default if the message is persistent it places it into the DLQ. If it isn't, nothing happens.
 
 Review comment:
   You should also point out that this only applies if the ACK mode is something other than auto which consumes them on dispatch to the client.
