This allows the proper resolving of lookups when performing constraint
validation involving Q and Case objects.
Thanks Andrew Roberts for the report and Sarah for the tests and review.

The section on manual testing, including how to use a local checkout of
Django, is moved from the contribution intro to the submitting patches
docs. This makes it easier for reviewers and authors to follow best
practices.

django.core.mail.get_connection() has always supported only variable
keyword arguments (never variable positional arguments).

When native support for tuple lookups is missing in a DB backend, it can
be emulated with an EXISTS clause. This is controlled by the backend
feature flag "supports_tuple_lookups".
The mishandling of subquery right-hand side in `TupleIn` (added to
support `CompositePrimaryKey` in Refs #373) was likely missed because
the only core backend we test with the feature flag disabled
(Oracle < 23.4) supports it natively.
Thanks to Nandana Raol for the report, and to Sarah Boyce, Jacob Walls,

Value(None, JSONField()) when used in When.condition incorrectly resolved with
for_save=True, resulting in the value being serialized as SQL NULL instead of
JSON null.

When matching which entry in the `Accept` header should be used for
a given media type, the specificity matters. However once those are
resolved, only the quality matters when selecting preference.

Thank you to Anders Kaseorg for the report.

The "q" key was removed while addressing ticket #36411. Despite
`MediaType.params` is undocumented and considered internal, it was used
in third-party projects (Zulip reported breakage), so this work restored
the `q` key in `params`.
Thanks Anders Kaseorg for the report.

The for_save flag wasn't properly propagated when resolving expressions, which
prevented get_db_prep_save() from being called in some cases. This affected
fields like JSONField where None would be saved as JSON null instead of SQL NULL.

Migrated remaining response-related logging to use the `log_response()`
helper to avoid potential log injection, to ensure untrusted values like
request paths are safely escaped.

Suitably crafted requests containing a CRLF sequence in the request
path may have allowed log injection, potentially corrupting log files,
obscuring other attacks, misleading log post-processing tools, or
forging log entries.
To mitigate this, all positional formatting arguments passed to the
logger are now escaped using "unicode_escape" encoding.

HttpRequest.get_preferred_type() did not account for parameters in
Accept header media types (e.g., "text/vcard; version=3.0"). This caused
incorrect content negotiation when multiple types differed only by
parameters, reducing specificity as per RFC 7231 section 5.3.2
(https://datatracker.ietf.org/doc/html/rfc7231.html#section-5.3.2).
This fix updates get_preferred_type() to treat media types with
parameters as distinct, allowing more precise and standards-compliant
matching.
