The following patches are making changes to shift from tenant -> project for all the references in devstack (it's not quite done yet, but this was done as a lot of small patches to make potential reverts easy) - https://review.openstack.org/#/q/topic:project_id+project:openstack-dev/devstack+status:open For the most part this shouldn't impact folks, as nothing in here should really be used outside of devstack. However some plugins might be impacted if they work off of variables that were not expected. https://review.openstack.org/#/c/301122/ - which makes changes to some of lib/neutron-legacy is the patch I would most expect to have that kind of side effects. If breaks happen, please let us know. The response is mostly going to be 'please update your plugins' unless there turns out to be a really bad issue. -Sean -- Sean Dague http://dague.net
