We haven't modified the 0-8 spec at all. Our thinking was that any 
client that was stuck on 0-8 was unlikely to get the attention needed to 
add support for new features.

That should really change!

It should just be a matter of swapping out the protocol spec file used 
by your codegen.

*goes and looks at php-amqplib*

Ah. That looks like it's not using any codegen. I would still suggest 
moving to 0-9-1. It should not be very hard.

A little bit. Some of the class / method numbers changed, and some 
methods gained or lost properties. But again, this shouldn't be a huge deal.

Cheers, Simon
