[zeromq-dev] zeroMQ version with ZMQ_STREAM_NOTIFY

The page you referenced says:

a) <strikeout>ZMQ_STREAM sockets now return an empty message upon client
connect and/or disconnect.</strikeout>
b) This no longer happens unless you set the ZMQ_STREAM_NOTIFY option on
the socket.

"a" is correct going from 4.0.x to 4.1.x so there shouldn't have been a
strikeout.
"b" *was* the case in 4.2 master but not any more.
