Hello, It seems the official Docker images are missing some important security updates [1][2]. Does anyone have any insight in how these packages get built and when? Their Dockerfile seems to come from here: https://github.com/docker-library/official-images/blob/master/library/centos (commit for "latest" says "update CentOS-7 - 20160331 - monthly build"). In the official Docker documentation [2] they suggest not running `apt-get upgrade` which I understood as don't run `yum -y upgrade` for CentOS. Any advice on whether it's best practice to always update packages or not?
