I've seen people use the 2.x branch on CentOS 6.4 a lot, which was released in April 2013. CentOS 6.8 is from May 2016, so already over two years old. Since CentOS supports upgrading between minor releases it seems reasonable to me to require CentOS 6.8. CentOS does not have maintenance releases, so by default upgrades always happen to the latest minor version.
Philip, do you feel strongly about supporting older releases? Do you have a particular one in mind?
