Fedora 20 is out – get it now from http://cloud.fedoraproject.org/

Import into glance:

     --container-format bare --is-public true --copy-from \

From an OpenStack point of view, one notable addition is the addition of the Heat tools provisioning images.

As with Fedora 19, cloud-init is configured to create a user fedora by default.
