----------------------------------------------+--------------------
Three items:
- Cleanup IS NOT NULL condition generation for negated lookups in
add_filter() (also fixes one bug, and simplifies split_exclude()). Handled
in commit:
https://github.com/akaariai/django/commit/4d8ed818beb59b1e6d04eead6c9dad0bf2bdafb7
- Removal of Query.join()'s promote kwarg. This also improves handling
of promotion in select_related(). Before select_related() always promoted
any used join if nullable, now only if the join is newly created. In case
there is already existing inner join we know any null value will remove
results in any case, so the louter join is wrong here. Commit:
https://github.com/akaariai/django/commit/f7f7044dedabdd04b6806409239e040c25d2bb83
- Cleaned up join promotion in combine(), commit:
https://github.com/akaariai/django/commit/bfc88e7e3dded3d4259d70f31d65d36b0e197144
I plan to commit these shortly.
