0.2.0

Please note, that our API is still not marked stable yet.

Breaking changes

• We have changed how logs() method works. It now returns iterator always. On
  top of it, we have implemented more convenience methods to return logs as
  bytes and unicode.

• Backend class can (and should) be used as a context manager. This was done
  for the sake of creating a temporary directory meant for the backend
  instance. The context manager ensures the temporary directory will be removed.

New Features

• We added support for docker-py version 1 so it can work in CentOS.
• conu will check whether required binaries are present and if not,
  CommandDoesNotExistException will be raised.
• Our documentation was improved and contains now more examples and the python
  interface should be explained in more detail.
• When creating docker containers, conu now utilizes option --cidfile.
• execute() method can be blocking and non-blocking.
• Backend provides new methods cleanup_containers() to cleanup containers
  created during the session.
