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.

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. Have questions about using Atomic? See the atomic (https://lists.projectatomic.io/mailman/listinfo/atomic) mailing list or find us in the #atomic channel on Freenode.
