* The upcoming release will contain multiple API breaking changes therefore the major version switch. It will support a subset of v.1.21 of the docker remote API. It also includes an experimental netty based implementation of `DockerCmdExecFactory` that probably will replace the current jersey/httpclient based one in a later release.

All changes

* [#410] (https://github.com/docker-java/docker-java/pull/410) Support for build-args of docker build

* [#396] (https://github.com/docker-java/docker-java/pull/396) Disable evaluation of http.proxy... variables when using unix socket connection

* [#393] (https://github.com/docker-java/docker-java/pull/393) Support ONBUILD instruction in Dockerfiles

* [#392] (https://github.com/docker-java/docker-java/pull/392) Introduce InspectContainerResponse.Mounts
