 ## 1.11.0 (2016-04-13)
 
 **IMPORTANT**: With Docker 1.11, a Linux docker installation is now made of 4 binaries (`docker`, [`docker-containerd`](https://github.com/docker/containerd), [`docker-containerd-shim`](https://github.com/docker/containerd) and [`docker-runc`](https://github.com/opencontainers/runc)). If you have scripts relying on docker being a single static binaries, please make sure to update them. Interaction with the daemon stay the same otherwise, the usage of the other binaries should be transparent. A Windows docker installation remains a single binary, `docker.exe`.
