Hello OpenStack community I'm one of the members of the StarlingX community. We've had a lot of stability issues with our ability to compile both our development branch and supported release branches these last few weeks. It all traces back to the Train EOL. We weren't monitoring openstack mailing lists, and missed the EOL announcement. We are actively moving off of Train, but aren't yet ready. What's really causing us grief is that some sub-projects, e.g.heat and nova, have started deleting elements of Train, e.g. git branches. Now please don't take this wrong. Ending support for an old branch is a totally normal thing, and we accept that. If StarlingX customers need support in that area, we'll provide it. However I would plea to you to NOT delete the elements of Train that allow other projects to compile old openstack releases, e.g. your gits branches. Sincerely Scott Little on behalf of StarlingX
