Log Message:
py-gunicorn: updated to 19.9.0

19.9.0:
* fix: address a regression that prevented syslog support from working
* fix: correctly set REMOTE_ADDR on versions of Python 3 affected by
  Python Issue 30205 <https://bugs.python.org/issue30205>_
* fix: show zero response length correctly in access log
* fix: prevent raising :exc:AttributeError when --reload is not passed
  in case of a :exc:SyntaxError raised from the WSGI application.
* The internal module gunicorn.workers.async was renamed to \ 
gunicorn.workers.base_async
  since async is now a reserved word in Python 3.7.
