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.

Hi, 
 
I am writing an application which uses ZMQ_STREAM sockets to provide an interface to \
non-zeromq applications on raw sockets. I know that there has been a change in the \
semantics of ZMQ_STREAM and a new option ZMQ_STREAM_NOTIFY \
has been introduced. I want to check the version in my code and set the option if \
necessary. Which version introduced the option? I guess it is 4.1.2. 
Cheers, 
 Jens
