Docker 1.11: The first runtime built on containerd and based on OCI technology

Docker Engine 1.11 has been released,built on runC and containerd. "runC is the first implementation of the Open Containers Runtime specification and the default executor bundled with Docker Engine. Thanks to the open specification, future versions of Engine will allow you to specify different executors, thus enabling the ecosystem of alternative execution backends without any changes to Docker itself. By separating out this piece, an ecosystem partner can build their own compliant executor to the specification, and make it available to the user community at any time - without being dependent on the Engine release schedule or wait to be reviewed and merged into the codebase."
