Yes, it'll be finalised fairly soon.

I don't personally view it as a new version, despite the name. It's 
really a very different thing, and is much more focussed on 
interoperability than 0-9-1 (i.e. 0-9-1 defines a broker model and gives 
you quite a few guarantees; 1.0 only really tells you how to get 
messages from point A to point B so it's easier to bolt on the side of 
an existing broker). In some ways it's more like a super-STOMP than 
prior versions of AMQP.

We have done some work on 1.0 support but I don't expect it'll be ready 
for prime time for quite a while.

Matthias hates it when I make forward-looking statements. But I find it 
very hard to imagine us removing support for 0-9-1 any time soon - loads 
of people use it, it gives you things 1.0 doesn't, and migrating is 
non-trivial.

For perspective, we also don't have any plans to remove 0-8 support. 
Lots of people still use *that* even though it's very similar to 0-9-1.

Cheers, Simon
