[rabbitmq-discuss] rabbitmq-erlang-client: How to configure connection's heartbeat ?

Thu Sep 2 14:14:12 BST 2010

Indeed, upgrading just the client(s) will break things for sure, since 
the clients now speak AMQP 0-9-1.
We do recommend upgrading all clients plus the server to version 2.0.0. 
There are many new features in it; including persistence to disk.
Note that the latest versions of broker and erlang client on default do 
not work together. We are working on fixing it. Use tag rabbitmq_v2_0_0 
instead, if you check source out from hg.

Rgds,
Vlad.
