2.7.0.dev (compared to 2.6.4)
-----------------------------
+- introduce the hook pytest_pyfunc_interpret_result
+ this eases interpreting test functions results like generators,
+ twisted inline defereds, futures and asyncio generators
+
+- replace the Generator concept with the pytest_pyfunc_interpret_result hook
+ (Note: this change reduces reporting detail for generator tests,
+ that will be addressed in a later release)
+
+ the Generator class is now a alias to Function
+
- add ability to set command line options by environment variable
PYTEST_ADDOPTS.
- fix issue655: work around different ways that cause python2/3
