Removed WSGI upgrade instructions for Django 1.3 and earlier.

    middleware up to version 2.0.7. In those cases the

    :data:`~django.core.signals.request_finished` signal isn't sent. This can

    result in idle connections to database and memcache servers.

Upgrading from Django < 1.4

---------------------------

If you're upgrading from Django 1.3.x or earlier, you don't have a

:file:`wsgi.py` file in your project.

You can simply add one to your project's top-level Python package (probably

next to :file:`settings.py` and :file:`urls.py`) with the contents below::

    import os

    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")

    from django.core.wsgi import get_wsgi_application

    application = get_wsgi_application()

The ``os.environ.setdefault`` line just sets the default settings module to

use, if you haven't explicitly set the :envvar:`DJANGO_SETTINGS_MODULE`

environment variable. You'll need to edit this line to replace ``mysite`` with

the name of your project package, so the path to your settings module is

correct.

Also add ``WSGI_APPLICATION = "mysite.wsgi.application"`` in your settings, so

that :djadmin:`runserver` finds your ``application`` callable. Don't forget to

replace ``mysite`` with the name of your project in this line.
