Thanks for the detailed updated and heads up about the approvals. There 
is one critical patch for Quantum:
https://review.openstack.org/#/c/17033/. The problem that we encountered 
was if namespaces are disabled and the DHCP agents device is not the 
first device in the routing table (for example if the L3 agents tap 
device is created first), then instances will not receive IP addresses 
from the DHCP agent.

There are a couple of other patches pending review for Quantum in the 
stable branch (I am just testing prior to pushing them). They are not 
critical for this release and can wait till the next.

I have added the patch for this - https://review.openstack.org/17036

I am going to be spending the rest of the day testing the stable branches.
