When updating our company's gunicorn I noticed the doc link for django was out of date. Looks like django removed all docs before 1.7. Another option, which would avoid updating these docs every few years would be to point those urls to dev, eg: https://docs.djangoproject.com/en/dev/howto/deployment/wsgi/gunicorn/
Thanks for the project!
update django doc url to 1.8 lts
