CoreOS has a rapidly incrementing version, 197.0.0, 247.0.0, and so on. It is a little known fact, but the version represents the number of days since the CoreOS epoch on July 1, 2013. And we hope to make 365.0.0 a particularly special release. Over the next week this release will go through our alpha and beta channels and, if all goes well, it will be the first version to be promoted to stable. So, watch along with us in the release channel to see if this is the one!
