If you do a yum update after install from any CentOS-7 install and if you choose to accept the updates then you are running the latest version of CentOS-7 (right now, 7.3.1611 + updates). CentOS-7 is the distro .. 7.0.1406, 7.1.1501, 7.2.1511, 7.3.1611 are 'point in time' releases of CentOS-7 .. the 14, 15 or 16 is the YEAR that Red Hat released the source code (2015 or 2016). The last two digits are the MONTH that Red Hat released that version of the Source Code. So, 7.0.1406 is based on the Source Code for RHEL 7.0 and was released in June of 2014. The latest point in time release is 7.3.1611 .. It is based on RHEL 7.3 Source Code, which was released in November of 2016. So, if you install 7.0.1406, then run yum update, you will be at 7.3.1611. If you want to know what version you are actually running do: cat /etc/centos-release It will look something like this: [jhughes@w541 ~]$ cat /etc/centos-release CentOS Linux release 7.3.1611 (Core) NOTE: If you are NOT running 7.3.1611 then your install is insecure. In order to keep you CentOS install secure, you must maintain it up to date by running 'yum update' periodically. This mailing list gets all mail daily forwarded as a digest from the centos-announce mailing list which lists updates. Here is an archive: https://lists.centos.org/pipermail/centos-announce/ Since 7.1.1503 source code was released in March 2015, your install would be missing all the updates listed there for 'CentOS 7' after March 2015 .. and also all updates listed on or after March 2105 on the CR announce list as well: https://lists.centos.org/pipermail/centos-cr-announce/ So your machine would be vulnerable to any update that is listed as 'security' in those months (including and after) March 2015, if you have not done updates. If you have done updates often, then you are running 7.3.1611. Thanks, Johnny Hughes
