Hello. Your PR seems okay, except that it lacks an entry in the changelog, as it was done in #37. Could you please add it to this branch? (including the fact that you had to disable the Python 2 tests ; I'll probably totally remove the Python 2 support in a more-or-less distant future)

ACK the reporter.
For Python 2 someone needs an ESM ubuntu version. It is hardly used anymore.
