We had a brief internal discussion about this today. We recommend
version 1.9 to anyone planning a release on the basis of what Open
vSwitch has available now or in the next few months. We should be
releasing OVS 1.9 really soon (within a week or two, I hope). I don't
know of anything we're working on in the 1.9 branch, so it probably
won't change further barring discovery of bugs (which could just as well
get discovered after release and end up in a 1.9.x release). It would
be perfectly reasonable to prepare for a release on the basis of the
What I really want to discourage (even though I doubt you are
considering it) is doing anything based on current master, because
there's been a lot of big changes in internal structure and I'm sure
more bugs will be discovered there before it's really ready.
