Description Michael Bayer 2017-07-05 13:59:59 UTC
There are some performance enhancements in the 1.1 series that stabilized as of 1.1.7, which specifically impact openstack services particularly Neutron which makes heavy use of the "joined eager loading" feature to a much larger extent in successive versions (mitaka, newton, etc), discussion at [1] [2] and followup fixes at [3].

There's no risk in going to 1.1.11 vs. 1.1.7, nor is there risk going just to 1.1.7 for now, the bug fixes between 1.1.7 and 1.1.11 are inert from an openstack perspective.
