Latest commit e8de9d1 May 11, 2016 @mateor mateor committed with kwlzn Update the futures library.
This bumps futures to a more modern version,
some useful Python libraries are pinned to a range
that is later than the current t.c. `futures` version.

ex. boto3 is pinned to `futures>=2.2.0,<4.0.0` for python2.7

This is the minimum-viable change that makes the t.c.
libs compatible.

Testing Done:
Ran locally and Travis passed: #428
