Deprecated depth kwarg on select_related.
...
This is the start of a deprecation path for the depth kwarg on
select_related. Removing this will allow us to update select_related so
it chains properly and have an API similar to prefetch_related.
Thanks to Marc Tamlyn for spearheading and initial patch.

Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.

the patch.

set manually after the load is updated on save.

Fixed #17788 -- Added batch_size argument to qs.bulk_create()

The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.
Thanks to everybody who participated in the discussions at Trac.

Fixed #17485 -- Made defer work with select_related
...
This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.
Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.
A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.

For this, the ``distinct()`` QuerySet method now accepts an optional

these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work.

Been meaning to do this for a long time. Mostly, this is a lot of

didn't cross-link foo() calls to itself, but everything else was
cross-linked to its main documentation.
