Yes, we're waiting till 1.11.6 lands - some important fixes for clouds in there. We've debated releasing at the same time as Kubernetes, but the feedback we've got is that users prefer that a kops release is ready to run, but we also need to do a better job of releasing alphas & betas earlier.
Obviously the current delay is not great - I'd much prefer for us to be on 1.12 (which actually has fixed the main issue already). I'm hoping we can catch up once we're (finally) done with the etcd3 migration.
