drf-extensions: version 0.3.1 is not compatible with DRF 3.8 and produces ImportError

The version 0.3.1 is not compatible with DRF 3.8. It seems that the master is, but the latest provided release to PyPI apparently not.

It produces an import error in the 0.3.1 code

Error:

  ...
  File ".../site-packages/rest_framework_extensions/routers.py", line 7, in <module>
    from rest_framework.routers import (
ImportError: cannot import name 'replace_methodname'
