Open Stack

Hi,

I have a question about how to mark stable branches as EOL when such branches
were not part of official releases at the moment of corresponding
releases but the
repositories which contain them became official after the release.

One example happens in a repository under the neutron team.
networking-odl is now part of the neutron governance but as of Ocata
release it was not official.
Ocata branches under the neutron stadium were marked as EOL recently,
but networking-odl
was not marked as EOL as it was not an official repository as of Ocata.

The openstack/releases repository handles official branches under a
specific release,
but all branches in official repositories are under control of the
openstack/releases repo.

I wonder how we can mark stable/ocata branch of networking-odl repo as
EOL and delete stable/ocata branch.
What is the recommended way to mark such branches described above as EOL?

Thanks in advance,
