CentOS virt - Apr 2018 - Apparent discontinuity between advertised centos7 release 1803_01 and content of centos-release file

Hello,

I searched centos7 in the AWS marketplace for the at-time-of-writing-latest
centos7 image:
https://aws.amazon.com/marketplace/pp/B00O7WM7QW?qid=1524138193326&sr=0-1&ref_=srh_res_product_title

I built a standard free tier t2.micro from this putative 1803_01 AMI.  I see
from the docs, this is thus a March 2018 compilation.
When I get CLI, I get this:

[centos at ip-172-31-27-32 etc]$ cat centos-release
CentOS Linux release 7.4.1708 (Core)

which suggests that the AMI I just launched was built on a version of centos
compiled from upstream sources in August 2017.
Does the release of centos7 on the marketplace sport a release version which
does not pertain to the machine's release? Unlike with releases published
outside AWS, the Centos <https://wiki.centos.org/Cloud/AWS> cloud page
does not specify version info as listed on AWS.

Thanks v much IA,

M

RHEL releases about every 6 months... and then CentOS lags behind a little bit
as a rebuilder.

The most current release of CentOS is based on RHEL 7.4... and is dated August
2017 (1708).  RHEL 7.5 was released a week or so ago and CentOS is frantically
working on coming out with CentOS release based on it.  When that comes out, the
latest release will be 1804 (or 1805, etc).

That doesn't mean there aren't in-between release updates because there
are... but they don't re-number the whole release because of regular
updates.

CentOS has a lot of products that they produce and some of them may be rebuilt
and distributed more frequently (like CentOS Atomic Host or their Vagrant image,
etc)... but not the oldest, main product.

Did that answer your question?

TYL,
