1.5.2:
Prelude
Fix py.test plugin with py.test < 3.0

Bug Fixes
Fixed a bug relating to how the pytest version was being discovered that meant \ 
new versions of pytest were being treated as old versions and would receive bad \ 
configuration.
The py.test plugin was broken when using py.test < 3.0. The version of \ 
py.test that ships in EPEL is only 2.7 so we need to make sure we support at \ 
least that version.

1.5.1:
New Features
The stream parameter is recorded when the request is sent and available in \ 
request history in the same was as parameters like verify or timeout.
