In order to apply the updates, login to your atomic host and run :
	sudo rpm-ostree upgrade

You can also see the Atomic history and rollback options via:
	sudo atomic status

In order to compare available rollback options, you can use the 'atomic
rpm diff' and 'atomic rpm list' commands.

Finally, you can rollback the changes using this atomic command; details
on the process are mentioned in the man page available via 'man atomic'
on the machine instance.

The repo is updated with all devel components going into the Atomic
host, including docker, cockpit, flannel, kubernetes and rpm-ostree
itself. Additionally, all CentOS Linux 7 updates are included as well.

Highlights from todays update include:
	cockpit 0.27
