I include the xen-unstable changeset number in the comments of
changesets from xen-unstable.  You should look for the latest
changeset with such a line:
hg -v history | sed -n '/^linux-2.6-xen-sparse cset:/ {p;q}'

Have you identified which changeset broke compatibility?  I'm always
watching for such changesets and it might be possible to add some
backwards compatibility without too much ugliness.  At least the
hypervisor/guest and xenbus/xenstore/guest interface should be
compatible within the xen 3.0 series...

The control interfaces (dom0) are not frozen. We'll be adding to and changing that interface as the control tools evolve. The event-channel change is an extension of the interface, which is entirely backwards compatible with the 3.0.0 release.
