I haven't touched on the changes.rst file. I wasn't quite sure if it's required for this type of change.

I'm not quite sure how to resolve this lint error. Can anyone give me a hint?

@leandrodesouzadev The automatically generated documentation for panels (https://django-debug-toolbar.readthedocs.io/en/latest/panels.html#debug_toolbar.panels.Panel) will contain a reference to your new GetResponse stub. The stub itself isn't documented however, so Sphinx doesn't know where GetResponse should point to.

Something like this fixes it:

I'm not sure if that's what we want. Maybe there's a different way to specify the type which doesn't require the GetResponse class to be documented as well? Or maybe documenting the stub itself (as a temporary measure, until Django ships type hints?) would be the way to go?

Will definitely take a look into it
