Rancher 1.6.27 release notes

Hi,

I see that Rancher 1.6.27 has been released less than 10 days ago on docker hub (https://hub.docker.com/r/rancher/server/tags), but I cannot find any release notes whatsoever and any information about docker compatibility - that is to say, what version of Docker I could use with this version on the Rancher Hosts, for instance.

Release announcement is at http://forums.rancher.com/t/rancher-release-v1-6-27 and GitHub release is at https://github.com/rancher/rancher/releases/tag/v1.6.27
