Log message:
py-django-cors-headers: updated to 2.2.0

2.2.0:
Django 2.0 compatibility. Again there were no changes to the actual library \ 
code, so previous versions probably work.
Ensured that request._cors_enabled is always a bool() - previously it could be \ 
set to a regex match object.

Log message:
py-django-cors-headers: added version 2.1.0

django-cors-headers is a Django App that adds CORS (Cross-Origin Resource
Sharing) headers to responses.

Although JSON-P is useful, it is strictly limited to GET requests. CORS builds
on top of XmlHttpRequest to allow developers to make cross-domain requests,
similar to same-domain requests.
