The new version of kgb made some changes that resulted in more strict

function signatures. While most of these were fixed, there were a few

signatures found that were not compatible with Django 1.11 (which added

new optional arguments not handled by our overriding functions). These

were fixed up to take variable arguments.
The @requires_user_profile decorator was also impacted, but in a

different way. It was checking for a particular attribute on a function

to determine if it was a spy, but the attribute chosen wasn't considered

public, and has since changed. This was updated to check for the unspy

method instead, which is safer and prevents unit tests from leaking

state.

Unit tests pass with kgb 2.0 for Django 1.6 and 1.11 (when used along

with other pending changes).
