Pytest 3.1.2 (2017-06-08)
Bug Fixes
* Required options added via pytest_addoption will no longer prevent using \ 
–help without passing them.
* Respect python_files in assertion rewriting.
* Fix recursion error detection when frames in the traceback contain objects \ 
that can’t be compared (like numpy arrays).
* UnicodeWarning is issued from the internal pytest warnings plugin only when \ 
the message contains non-ascii unicode (Python 2 only).
* Added a workaround for Python 3.6 WindowsConsoleIO breaking due to \ 
Pytests’s FDCapture. Other code using console handles might still be \ 
affected by the very same issue and might require further workarounds/fixes, \ 
i.e. colorama.
