As of 3.2, the filtering happens on the publisher side for inproc, tcp and IPC 
transports. For the epgm transport, filtering is still (and forever will be) on 
the client side.

So, I recommend submitting a pull request to correct the information under 
"Getting the Message Out" and clarifying the issue of filtering based on 
transport type. Thanks.
