No, it doesn't. This was actually specified before 0.10, but we felt
that the actual specification of this was

a) not clear enough to produce a tractable implementation;
b) significantly more difficult that the other types of exchanges;
c) until now, not that many have been asking about it;

so we deferred its implementation until sufficient spec clarification
and justification came to be.

This is in the pipeline, but there is no ETA for it at the moment.

So the exchange types you currently have with Rabbit are the direct,
fanout and topic exchanges.

Have a look at the compatibility information for Rabbit:


Version 0.91 (as a service pack for 0.9) is currently being reviewed
by the working group and when this is signed, we will implement that.
