[rabbitmq-discuss] Python Client for RabbitMQ/AMQP?

Thu Aug 23 20:59:06 BST 2007

I was thinking that I could probably get the Java Qpid broker to support
AMQP 0-9 (non-WIP) if there is demand.  For the production uses of Qpid that
I know about 0-8 is all that will be used however.

Martin - does OpenAMQ still accept clients wanting to talk 0-8 to it?  I
can't remember any changes off the top of my head between 0-8 and 0-9
(non-WIP) that would prevent a 0-9 broker from accepting communication from
a 0-8 client [sorry for hijacking a Rabbit-MQ list for a Qpid / OpenAMQ
question].

Thanks,
Rob
