Missing documentation on removal of cleanupregistration

[pjrobertson]

I've just upgraded django-registration, and noted that the cleanupregistration management command is not available. I couldn't find any reference to this being removed in the official docs, however a complex Google search led me to this file: https://django-registration.readthedocs.io/_/downloads/en/2.3/pdf/ which mentions cleanupregistration is deprecated.

The Upgrading from previous versions notes should include when this cleanupregistration management command was removed, and the alternative suggested. Currently, the FAQ part saying how to delete expired unactivated accounts is very bare of information as well.

Update: It looks like it was removed sometime in 2.x. Here's the latest reference I can find, which basically calls this. It says it'll be removed in 3.0 - I guess that's what's needed for the docs.
