v2.1.1

Per project config files
In addition to the global, user-specific config file, it is now possible to add a local project-specific config file in the root of your project.

The config must be named.backportrc.json and have the following structure:

{
  "upstream": "elastic/kibana",
  "branches": ["6.x", "6.1", "6.0"]
  "labels": ["backport"]
}
