Docker version included old

Hi,
The docker version included with the latest release  (v1.17.0) of Minishift Centos iso is old. It is 1.13.1. I would request that a new ISO with latest Docker be released.
This issue seems to have remained unresolved for quite some time now [ https://github.com/minishift/minishift/issues/3278  https://github.com/minishift/minishift/issues/3434 ]

regards
