It's a recommended OVS version to build with.  I'd not recommend using
it to actually build ovs-vswitchd or ovsdb-server, because it will
mean that you're running non-released version of OVS that is always
behind even the master branch.

Looking at the OVN documentation from this perspective I see that it
very loose in operation with word "use".  I think it should mean "build with",
but it's definitely not obvious.

I've sent a patch to clarify the documentation:

Best regards, Ilya Maximets.
