Removing a backend configured in AUTHENTICATION_BACKENDS should not

logged-in users disconnect.
Thanks Bradley Ayers for the report.

#20432: Fix for GroupAdmin test

Also, streamline the use of 0 and None between cache backends.

Fixed argument order for localized_fields to ensure backwards compatibility

Fixed #19919: get_language_from_request() disregards en-us and en

when matching Accept-Language

Thanks Stephane Benchimol for the report and the initial script and
mfandreas for the patch.

Fixed #13546 -- Easier handling of localize field options in ModelForm

Fixes #20235 - MultipleObjectMixin requires object_list in kwargs

This is so MultipleObjectMixin can be used in the same way as
SingleObjectMixin.

It can fail in hard-to-diagnose ways.

Fixed #20433: extracted catalog compilation code from view.

Made introspection always return a unicode as column name on Oracle.
Thanks aaugustin for review and suggestion to use force_text().

The failure was triggered by a cache leak.

Thanks srusskih for the report and Aymeric Augustin for the review.

Thanks to edevil for the report and saz for the patch.

Fix makemessage's --ignore patterns being applied to the full path
instead of the file name. Thanks to nnseva for the report and the
original patch.

This completes the removal of the distinction between core devs and
specialists.

commit.

Thanks Lennart Regebro for spotting that code.

Thanks Lennart Regebro for pointing it out.

refs #16319, thanks to bmispelon for the catch

Thanks to Joel Hansson for the suggestion and Curtis Maloney for the initial
patch.

Largely inspired from django-floppyforms. Designed to not depend
on OpenLayers at code level.

The distinction's not really one we make any more, so updated the docs
accordingly.
