-----
* Default API version is now 1.12 (support for docker 1.0)
* Added new methods `Client.get_image` and `Client.load_image`
(`docker save` and `docker load`)
* Added new method `Client.ping`
* Added new method `Client.resize`
* `Client.build` can now be provided with a custom context using the
`custom_context` parameter.
* Added support for `memswap_limit` parameter in `create_container`
* Added support for `force` parameter in `remove_container`
* Added support for `force` and `noprune` parameters in `remove_image`
* Added support for `timestamps` parameter in `logs`
* Added support for `dns_search` parameter in `start`
* Added support for `network_mode` parameter in `start`
* Added support for `size` parameter in `containers`
* Added support for `volumes_from` and `dns` parameters in `start`. As of
API version >= 1.10, these parameters no longer belong to `create_container`
* `Client.logs` now uses the logs endpoint when API version is sufficient
Bugfixes
* Fixed a bug in pull where the `repo:tag` notation wasn't interpreted
properly
* Fixed a bug in streaming methods with python 3 (unicode, bytes/str related)
* Fixed a bug in `Client.start` where legacy notation for volumes wasn't
supported anymore.
Miscellaneous
* The client now raises `DockerException`s when appropriate. You can import
`DockerException` (and its subclasses) from the `docker.errors` module to
catch them if needed.
* `docker.APIError` has been moved to the new `docker.errors` module as well.
* `Client.insert` is deprecated in API version > 1.11
* Improved integration tests should now run much faster.
* There is now a single source of truth for the docker-py version number.
