I'm sure, you won't need to re-install openstack-dashboard at all. Editing/changing the ALLOWED_HOSTS setting is nothing we can or should do during install/upgrade phase at all. This does not need any package change, but docs.
Upgrade info is now in the Release Notes; moving there.
This bug is being assigned to ddomingo, who is now the designated docs specialist for Release Notes after 4.0.z2.
