drf-yasg 1.20.0

on Python PyPI

• IMPROVED: updated swagger-ui to version 3.36.0
• IMPROVED: updated ReDoc to version 2.0.0-rc.40
• FIXED: fixed compatibility with Django Rest Framework 3.12
• FIXED: fixed compatibility with Python 3.9 typing generics
• FIXED: dropped support for obsolete django.conf.settings.LOGOUT_URL (#646)

Support was dropped for Python 2.7, DRF 3.8, DRF 3.9.
Requirements are now: Python>=3.6, Django>=2.2, DRF>=3.10

The 1.18 and 1.19 series was skipped to avoid confusion with the drf-yasg2 fork. I would also like to take this
opportunity to extend my apologies to the community at large for the large gap in the maintenance of drf-yasg
and the problems it has caused.
