Re: Propose to update the minimal supported Docker version in Mesos to Docker 1.8.0

[Gilbert Song <gi...@mesosphere.io>]

We are considering to backport this fix to Mesos 1.6.x, 1.5.x and 1.4.x,
which means starting from 1.4.x your minimum docker version will be bumped
to Docker 1.8.0 (an old docker daemon version).

Please reply on this thread if this is a breaking change for you. Thank you!
