Hi StarlingX Community. We had a topic during the Community Call today about build issues due to the deletion of end-of-life (EOL) branches in OpenStack. I did a little bit of digging, and found out that this is part of a process that has been in place for a long time now. You can find more information about the different phases of the release lifecycle of OpenStack projects and branches: https://docs.openstack.org/project-team-guide/stable-branches.html#maintenan... The main takeaway is to rather rely on tags than branches, since tags live forever while branches are ephemeral. I hope this helps. Thanks and Best Regards, Ildikó ——— Ildikó Váncsa Director of Community Open Infrastructure Foundation
