Previously, the admin panel only worked with the integration setup. This version ensures that the admin panel can be imported in other setups, such as when using django-improved-user in demo situations with the extension setup (as shown in the quickstart).
Please note that developers should create their own User admin panel for production sites when using the extension setup. The replacement setup always necessitates the creation of a custom admin panel.
Please see the (expanded) documentation about admin usage for more details.
