[openstack-dev] [kolla] How tied is kolla to matching 1:1 releases of openstack?

Hi Joshua,

Thanks for sharing your workflow, interesting to see.

To answer your question, there is a 1:1 relationship between Kolla and 
OpenStack releases. As Kevin outlined, you may get lucky, currently in 
Oracle we deploy OpenStack Mitaka with Kolla Newton and for the most 
part it works fine. But it's not recommended from an upstream point of view.

Maybe we need more discussion on that as it's something I see popping up 
frequently. We also have a warning in the docs around this, see
