bzr version upgrade tomorrow

I would like to upgrade the bzr version on squid-cache.org tomorrow.
This does not require client upgrades. Those of you with current clients
will be seeing 'Server is too old for fast get_parent_map, reconnecting.
(Upgrade the server to Bazaar 1.2 to avoid this)' when you use bzr+ssh -
the upgrade will fix this (and make bzr update and first checkout
massively faster)
