upstream work was done for the mitaka cycle
Comment 5 Sahid Ferdjaoui 2016-03-10 11:39:57 UTC 
The code is still waiting for review downstream. I hope some of guys in our team can do it soon. I actually did some tests and the backport seems to work.

Comment 6 Scott Lewis 2016-03-22 12:57:54 UTC 
Eoghan,
Has this been delivered for the OSP 8 GA? If not, it will need to move to 8.0.z unless Steve determines it is a blocker.
Comment 7 Sahid Ferdjaoui 2016-03-24 17:24:03 UTC 
This feature is not going to be backported to OSP8 - It has been decided by the engineering team [1] that since it use objects version we can ensure the backport will work in every cases of an upgrade.

Comment 10 Robert Love 2016-06-09 14:53:43 UTC 
Will this feature be supported in OSP9?
Comment 11 Stephen Gordon 2016-06-09 15:17:23 UTC 
Hi Rob,

The bug tracking support for this for OSP 9 is https://bugzilla.redhat.com/show_bug.cgi?id=1277736 - out intent is to support it and we are working on testing.

Thanks,

Steve
