App engine default Django version change

Question

Since app engine 1.4.2 was released, I am getting warnings like this in my production logs:

You are using the default Django version (0.96). The default Django version will change in an App Engine release in the near future. Please call use_library() to explicitly select a Django version. For more information see http://code.google.com/appengine/docs/python/tools/libraries.html#Django

This occurs on every handler where I use a Django template - via the following:

from google.appengine.ext.webapp import template

I'd like to upgrade to 1.2, however the following links don't seem very clear on exactly how to do this (or whether it works at all):

• http://code.google.com/appengine/docs/python/tools/libraries.html#Django
• http://code.google.com/p/googleappengine/issues/detail?id=1758
• http://code.google.com/p/googleappengine/issues/detail?id=4489
• http://www.mediacrafters.org/post/django11-on-appengine

The common thread is to insert this:

from google.appengine.dist import use_library
use_library('django', '1.2')

However, in what file(s) should this be inserted:

1. Just in appengine_config.py?
2. In every .py file which does from google.appengine.ext.webapp import template?
3. In every .py file in the project?
4. In 1 and (2 or 3) above, and also add import appengine_config to those files?
5. In 3 or 4, and also add wrappers around built-in functions like appstats, remote api, datastore admin, etc?
6. Something else?

Thanks.
