${version}-0.1.0b3 -> ${version}-0.1${milestone}

we have rc1 now

delorean delorean@rdoproject.org -> RDO rdo-list@redhat.com

We don't check that upstream_version fallback macro is defined
%{!?upstream_version: %global upstream_version %{version}%{?milestone}}

Typo line 28 {?dist} => %{?dist}

$pkg.spec doesn't work for openstack-* packages
you could replace it everywhere with *.spec - in distgit there can be only one .spec file
