3.7.0

List of PRs / issues for this release

Features

• Added support for multiplexed streams (for attach and exec_start). Learn
  more at https://docker-py.readthedocs.io/en/stable/user_guides/multiplex.html
• Added the use_config_proxy parameter to the following methods:
  APIClient.build, APIClient.create_container, DockerClient.images.build
  and DockerClient.containers.run (False by default). This parameter
  will become True by default in the 4.0.0 release.
• Placement preferences for Swarm services are better validated on the client
  and documentation has been updated accordingly

Bugfixes

• Fixed a bug where credential stores weren't queried for relevant registry
  credentials with certain variations of the config.json file.
• DockerClient.swarm.init now returns a boolean value as advertised.
