The CentOS Atomic SIG has released an updated version
(https://wiki.centos.org/SpecialInterestGroup/Atomic/Download) of
CentOS Atomic Host (7.1712), a lean operating system designed to run
Linux containers, built from standard CentOS 7 RPMs, and tracking the
component versions included in Red Hat Enterprise Linux Atomic Host.
This release includes updated kernel[1], linux-firmware[2] and
microcode_ctl[3] packages to address recent security advisories,
alongside other minor updates that shipped during the month of
December.

## Upgrading
If you're running a previous version of CentOS Atomic Host, you can
upgrade to the current image by running the following command:
# atomic host upgrade
## Release Cycle
The CentOS Atomic Host image follows the upstream Red Hat Enterprise
Linux Atomic Host cadence. After sources are released, they're rebuilt
and included in new images. After the images are tested by the SIG and
deemed ready, we announce them.
## Getting Involved
CentOS Atomic Host is produced by the CentOS Atomic SIG
(http://wiki.centos.org/SpecialInterestGroup/Atomic), based on
upstream work from Project Atomic (http://www.projectatomic.io/). If
you'd like to work on testing images, help with packaging,
documentation -- join us!
The SIG meets every two weeks as part of the Project Atomic community
meeting at 16:00 UTC on Monday in the #atomic channel. You'll often
find us in #atomic and/or #centos-devel if you have questions. You can
also join the atomic-devel
(https://lists.projectatomic.io/mailman/listinfo/atomic-devel) mailing
list if you'd like to discuss the direction of Project Atomic, its
components, or have other questions.
## Getting Help
If you run into any problems with the images or components, feel free
to ask on the centos-devel
(http://lists.centos.org/mailman/listinfo/centos-devel) mailing list.
