Docker 1.13.1 entered development about 10 days ago and it received only two Release Candidate (RC) builds during its cycle. It comes approximately three weeks after the launch of Docker 1.13.0 to address a few recently discovered regressions, as well as to implement a couple of new features. First of all, Docker 1.13.1 comes with a little warning for GNU/Linux users, as it would appear that you’ll need to manually configure the storage driver of devicemapper, if your distribution is using it, to use overlay or overlay2 by default where it’s supported by the kernel, of course.
