In general

hg up -C default

for both the client and the server will do the trick.

This is because the default branch of Rabbit differs quite a bit from
the 1.5.x series, i.e. the default branch contains a lot of new
features (and internal API changes) that will be released in 1.6.0,
whereas 1.5.3 is a maintenance release that does not include any new
features.

When the Erlang client is released, specific client and server
versions will be locked down. Until then, we will always sync the
default branches of both trees.

Having just that I've just run the test suite with the latest
respective trees and have noticed that the QOS test breaks the suite
because it internally waits 15 secs to do what it has to do, but eunit
times out after 5 seconds :-( Need to fix this, obviously.

HTH,

Ben
