- Migration of Docker Toolbox images is not proposed anymore in Docker For Mac installer (still possible to migrate Toolbox images manually).


### Docker Community Edition 17.12.0-ce-mac45 2018-01-05


* Upgrades
  - [Docker 17.12.0-ce](https://github.com/docker/docker-ce/releases/tag/v17.12.0-ce)

* New
  - Experimental Kubernetes Support. You can now run a single-node Kubernetes cluster from the "Kubernetes" Pane in Docker For Mac Preferences and use kubectl commands as well as docker commands. See [the Kubernetes section](/manuals/desktop/features/kubernetes.md)
  - DNS name `docker.for.mac.host.internal` should be used instead of `docker.for.mac.localhost` (still valid) for host resolution from containers, since since there is an RFC banning the use of subdomains of localhost (See https://tools.ietf.org/html/draft-west-let-localhost-be-localhost-06).

* Bug fixes and minor changes
  - The docker engine is configured to use VPNKit as an HTTP proxy, fixing 'docker pull' in environments with no DNS. Fixes [docker/for-mac#2320](https://github.com/docker/for-mac/issues/2320)

* New
  - For systems running APFS on SSD on High Sierra, use `raw` format virtual machine disks by default. This increases disk throughput (from 320MiB/sec to 600MiB/sec in `dd` on a 2015 MacBook Pro) and disk space handling.
  Existing disks are kept in qcow format, if you want to switch to raw format you need to "Reset to factory defaults". To query the space usage of the file, use a command like:
  `$ cd ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/`
  `$ ls -ls Docker.raw`
  `3944768 -rw-r--r--@ 1 user  staff  68719476736 Nov 16 11:19 Docker.raw`
