Thanks Ramiro for the report.

Thanks Xelnor for the patch.

There were multiple cases where join promotion was a bit too aggressive.
This resulted in using outer joins where not necessary.

Refs #21150.

Added tests for a .annotate().select_related() join promotion failure.
This happened to work on master but was currently untested.

Thanks to berkerpeksag for the report and to claudep
for the review.

Thanks bartTC for the report.

Don't set a global default interpreted role function for reStructuredText.
Instead, use the `default-role` directive to change the default only within
the `parse_rst()` function.

Thanks Malcolm Tredinnick for the report.

Added docs/internals/mailing-lists.txt documenting the use of django's
mailing lists. All references across docs changed to point to this page.

The referencing makes use of substitution because there's no way to make
a :ref: link in a non-inline fashion in Sphinx. It also makes use of
rst_epilog Sphinx conf for making this substitutions across all the
docs.

Thanks Melevir for the suggestion.

Thanks ryan at ryangallen.com for the report.

Thanks ppetrid at yawd.eu for the suggestion.

Fixed #19182 -- Fixed ModelAdmin.lookup_allowed to work with ('fieldname', SimpleListFilter) syntax.

Thanks gauss for the report.

Thanks Michael Manfre for the report, Raphaël Barrois for the patch and
Claude Paroz, Aymeric Augustin for the reviews.

Refs #7936.

Thanks Jaime Irurzun for the report and initial patch and
ejucovy for the test.

Thanks neithere for the suggestion.

- Fixed test that didn't close the files it opened
- Caught and handled exception when temp directory cannot be removed

Thanks Tuttle for the report.

Take in account platform path separator. Refs #19552.

os.symlink() is available starting with Windows Vista but can fail at
runtime.

Literals from source files with Django template language syntax don't
have a '.py' suffix anymore.

Also, the '.\' prefix is preserved to respect GNU gettext behavior on
that platform.

Refs #16903.

Thanks rm_ for the suggestion.

The precision of time.time() is OS specific and it is possible for the
resolution to be low enough to allow reading a cache key previously set
with a timeout of 0.

Test models introduced for #10733 didn't contain default value for
a BooleanField(). Check command didn't like that -> check tests failed.

In queries using .defer() together with .select_related() the values
and fields arguments didn't align properly for resolve_columns().

refs #17671

The bug was reported pre 1.1, and somewhere along the way it has been
fixed. So, this is tests only addition.

Thanks ramiro for the report.

Thanks Aymeric Augustin for the suggestion. Refs #21165.

Avoid accessing query.extra and query.aggregates directly for .values()
queries. Refs #20950.
