It's not a new feature. You may have seen is discussions involving 
scenarios which fall outside the conditions for which the ordering 
guarantees apply. It is all too easy to end up in such situations. In 
particular note the "unless the redelivered field is set" condition, 
which means any disconnect by consumers can cause messages pending 
acknowledgement to be subsequently delivered out of order.
