Manually logging out a user, after a site update in Django

I have a website, which will be frequently updated. Sometimes changes happen to User specific models and are linked to sessions.

After I update my site, I want the user to log out and log back in. So I would log out the user right then. If he logs back in, he will see the latest updates to the site.

How do I do it?
