Changes between Version 2 and Version 4 of Ticket #37372

v2	v4
8	8	#20024 was created 14 years ago. The suggested change made sense back then, but conflicts with the fix for #31667 implemented in the meantime. This led to the fix for #20024 being ineffective, and the targeting of null values in `__in` lookups being made impossible.
9	9
10		A bit more context for 2.: It was decided to discard None from the rhs for `__in` lookups with `.filter()`, since NULL is never equal to anything. That means that the None values have to be included in the `.exclude()` queryset in order for `.filter()` and `.exclude()` to produce complementary querysets.
