Gasp !!
We have hundred  of processes running zmq 3.1 (nicely).
We have started with ZMQ 3.0 which has been made incompatible with ZMQ 
3.1. We moved to 3.1 and  now 3.2.1 is  incompatible.

For application users, these incompatibilities generate quite some 
trouble and make our life more complicated.
