95394443bf Fixed #36786 -- Fixed XML serialization of None values in natural keys. 
None values in natural keys were incorrectly serialized as the string
"None", causing deserialization to fail for fields like UUIDField.

93540b34d4 Fixed #35729 -- Enabled natural key serialization opt-out for subclasses. 
Refactored serialization logic to allow models inheriting a natural_key()
method (e.g. AbstractBaseUser) to explicitly opt out of natural key
serialization by returning an empty tuple from the method.

Thanks Jonas Dittrich for the report.

50efb718b3 Fixed CVE-2025-64460 -- Corrected quadratic inner text accumulation in XML serializer. 
Previously, `getInnerText()` recursively used `list.extend()` on strings,
which added each character from child nodes as a separate list element.
On deeply nested XML content, this caused the overall deserialization
work to grow quadratically with input size, potentially allowing
disproportionate CPU consumption for crafted XML.

The fix separates collection of inner texts from joining them, so that
each subtree is joined only once, reducing the complexity to linear in
the size of the input. These changes also include a mitigation for a
xml.dom.minidom performance issue.

Thanks Seokchan Yoon (https://ch4n3.kr/) for report.

b9aa3239ab Refs #21286 -- Fixed YAML serialization of TimeField primary key. 
Handling for PyYAML not being able to serialize `datetime.time`
values is moved from `handle_field` to `_value_from_field` as only
non-primary key, non-relation fields are passed into `handle_field`.

FileField/ImageField cannot be primary keys, so serialization support
for this case will not be implemented.

517d3bb4dd Fixed #34779 -- Avoided unnecessary selection of non-nullable m2m fields without natural keys during serialization. 
By using `select_related(None)` instead of `select_related()`, the
unnecessary joins are completely avoided. Note that the current tests
already covers the change, when the field is not `null=True`.

Regression in f9936deed1.

5779cc938a Fixed #31071 -- Disabled insert optimization for primary keys with defaults when loading fixtures. 
Model.save_base() is called directly when loading fixtures and assumes
existing rows will be updated. Branching of "raw" allows to maintain
the optimization introduced in #29260 while supporting this edge case.

Regression in 85458e94e3.
