Can I update to docker 1.12 for rancher?

Is rancher compatibility with docker 1.12 ? May I update to docker 1.12 for rancher ?

Rancher currently does not support Docker 1.12. We typically will announce when we support the next Docker version and it will not occur until after Docker has officially released their version (they are currently on rc2).

Any update on this one? When will v1.2 be released?

Rancher 1.2 is targetted for end of October.
