Hi all,
I'm trying to clarify the security updates policy for older CentOS-7 releases.
There is a number of servers I'm supporting that are running CentOS-7 1503. When 1511 was released several days ago I've tried to upgrade several of those, but failed. I've got some strange errors with e1000 virtual NIC being restarted frequently with 'tx unit hang' errors. Anyway, it's not the thing I'd like to discuss here.
What I'd like to know is the answer to the question "will there be any security updates for CentOS-7 1503, and how long"? I was searching on a wiki, but couldn't find anything clear enough. What I've found is the phrase in 1511 announcement letter
This release supersedes all previously released content for CentOS Linux 7, and therefore we highly encourage all users to upgrade their machines. Information on different upgrade strategies and how to handle stale content is included in the Release Notes.
This makes me think that there will be no security updates for 1503 and the only way to get them is to upgrade to 1511, but I'd like to find any proof. Unfortunately, there is nothing about this in Release Notes :(
