## Back to the future !

## Delorean

Tracks upstream master (currently Mitaka) and stable branches now.

Breaks when upstream change requires packaging changes and alerts package owners as defined in [rdoinfo](https://github.com/redhat-openstack/rdoinfo)

Going forward, all packaging changes will be done in Delorean packages first, and merged to stable packaging branches
