* Bug fixes and minor changes
  - Revert the default disk format to qcow2 for users running macOS 10.13 (High Sierra). There are confirmed reports of file corruption using the raw format which uses sparse files on APFS.

### Docker Community Edition 17.12.0-ce-mac46 2018-01-09

* Upgrades
  - [Docker 17.12.0-ce](https://github.com/docker/docker-ce/releases/tag/v17.12.0-ce)
  - [Docker compose 1.18.0](https://github.com/docker/compose/releases/tag/1.18.0)

  - For systems running APFS on SSD on High Sierra, use `raw` format VM disks by default. This improves 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 "Remove all data" or "Reset to factory defaults".
  - 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.

  - Daemon restart button has been moved to settings / Reset Tab.
  - Better VM state handling & error messages in case of VM crashes.
  - Fix login into private repository with certificate issue. (See [docker/for-mac#2201](https://github.com/docker/for-mac/issues/2201))

- Crash reports are sent over Bugsnag rather than HockeyApp

- Fixed an issue where some windows did not claim focus correctly

- Added UI when switching channel to prevent user losing containers and settings

- Check disk capacity before Toolbox import

- Import certificates in `etc/ssl/certs/ca-certificates.crt`

- disk: make the "flush" behaviour configurable for database-like workloads. This works around a performance regression in 1.12.1.

**Networking**

- Proxy: Fixed application of system or custom proxy settings over container restart

- DNS: reduce the number of UDP sockets consumed on the host

- VPNkit: improve the connection-limiting code to avoid running out of sockets on the host

- UDP: handle diagrams bigger than 2035, up to the configured macOS kernel limit

- UDP: make the forwarding more robust; drop packets and continue rather than stopping

**File sharing**

- osxfs: Fixed the prohibition of chown on read-only or mode 0 files, (fixes
  [docker/for-mac#117](https://github.com/docker/for-mac/issues/117),
  [docker/for-mac#263](https://github.com/docker/for-mac/issues/263),
  [docker/for-mac#633](https://github.com/docker/for-mac/issues/633))

- osxfs: Fixed race causing some reads to run forever

- osxfs: Fixed a simultaneous volume mount race which can result in a crash

**Moby**

- Increase default ulimit for memlock (fixes [docker/for-mac#801](https://github.com/docker/for-mac/issues/801))
