Removed the can_return_columns_from_insert skip gates on existing
field_defaults tests to confirm the expected number of queries are
performed and that returning field overrides are respected.
Updated docs for class django.core.mail.EmailMessage to use Sphinx
`method::` directives, allowing cross references to those methods
elsewhere in the docs.
Updated references to those methods in the email docs and 6.0 release
notes to link directly to the specific methods.
Renamed existing methods and abstractions used for INSERT … RETURNING
to be generic enough to be used in the context of UPDATEs as well.
This also consolidates SQL compliant implementations on
BaseDatabaseOperations.
Lines in the docs files were manually adjusted to conform to the
79 columns limit per line (plus newline), improving readability and
consistency across the content.
Introduced `{% partialdef %}` and `{% partial %}` template tags to
define and render reusable named fragments within a template file.
Partials can also be accessed using the `template_name#partial_name`
syntax via `get_template()`, `render()`, `{% include %}`, and other
template-loading tools.
Adjusted `get_template()` behavior to support partial resolution, with
appropriate error handling for invalid names and edge cases. Introduced
`PartialTemplate` to encapsulate partial rendering behavior.
Includes tests and internal refactors to support partial context
binding, exception reporting, and tag validation.

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.
- Changed EmailMessage.message() to construct a "modern email API"
email.message.EmailMessage and added policy keyword arg.
- Added support for modern MIMEPart objects in EmailMessage.attach()
(and EmailMessage constructor, EmailMessage.attachments list).
- Updated SMTP EmailBackend to use modern email.policy.SMTP.
Deprecated:
- Attaching MIMEBase objects (replace with MIMEPart)
- BadHeaderError (modern email uses ValueError)
- SafeMIMEText, SafeMIMEMultipart (unnecessary for modern email)
- django.core.mail.forbid_multi_line_headers()
(undocumented, but exposed via `__all__` and in wide use)
- django.core.mail.message.sanitize_address()
(undocumented, but in wide use)
Removed without deprecation (all undocumented):
- EmailMessage.mixed_subtype
- EmailMultiAlternatives.alternative_subtype
- Support for setting (undocumented) EmailMessage.encoding property
to a legacy email.charset.Charset object
Related changes:
- Dropped tests for incorrect RFC 2047 encoding of non-ASCII email
address localparts. This is specifically prohibited by RFC 2047, and
not supported by any known MTA or email client. (Python still
mis-applies encoded-word to non-ASCII localparts, but it is a bug that
may be fixed in the future.)
- Added tests that try to discourage using Python's legacy email APIs
in future updates to django.core.mail.
In public mail APIs, changed less frequently used parameters from
keyword-or-positional to keyword-only, emitting a warning during the
required deprecation period.
