Calling render on a Template object passing a dict fails

[Eddie Bragg]

According to the release docs for 1.11 any callto render() on a Template object you need to pass a dict
​https://docs.djangoproject.com/en/1.11/releases/1.11/#django-template-render-prohibits-non-dict-context

I have code that originally passes a Context object.
Upgrading to 1.11 from 1.10 and changing it to a dict causes this error 'dict' object has no attribute 'render_context'

Looking at Django code the error occurs at ​https://github.com/django/django/blob/1.11/django/template/base.py#L203
I believe this code still expects a Context object.
