--- fixes: - | Previously a network's ``dns_domain`` attribute was ignored by the DHCP agent. With this release, OpenStack deployments using Neutron's DHCP agent will be able to specify a per network ``dns_domain`` and have instances configure that domain in their dns resolver configuration files (Linux's /etc/resolv.conf) to allow for local partial DNS lookups. The per-network ``dns_domain`` value will override the DHCP agent's default ``dns_domain`` configuration value. Note that it's also possible to update a network's ``dns_domain``, and that new value will be propogated to new instances or when instances renew their DHCP lease. However, existing leases will live on with the old ``dns_domain`` value.
