Thanks Russell for the report, Marc for the initial patch, Carl for the
final review, and everyone who contributed to the design discussion.

Thanks Aymeric for design discussion.

During the admin check for list_editable _check_list_editable_item
should return an empty list if all checks pass. Additionally the
Testcase test_readonly_and_editable was changed to test what the
name implies instead of duplicating the logic of test_readonly.

Thanks tragiclifestories for the report.

Maths is hard.

We fork at beta. This branch will be recreated when the first beta is created.
It has been merged in to maintain the version number bump and tag.

We should branch after the first beta.

We did this for 1.6 and it was very effective. 95%+ of fixes which merge
during the alpha are backported, as the policy is "all but really major
features". It's easier to just not merge any really major features.
After beta, we have feature freeze so we need to backport bugs to stable
but not features, so then the branch makes sense.

Fixes #21864: Close string in example of custom lookups doc page.

Thanks to Chris Barna for the report.

Thanks marktranchant.

This is consistent with Python's official documentation
and it's a sphinx recommendation too[1].

Refs #21855.

Thanks Giggaflop and Jennifer Casavantes.

Thanks russellm for the report.

Fixed #21852 -- Make migration writer serialize iterators

We need to figure out how to deprecate django-admin.py, but for now this
should do the trick.

Fixed typo on docstring
