Fixed #37023 -- Made XML serializer put each ManyToManyField object on its own line.

Fixed #36750 -- Made ordering of M2M objects deterministic in serializers.

Modified tests to format PKs with %s rather than %d.

2026-02-10T21:04:24Z

It's how Django formats values internally and makes tests compatible with databases that use non-integer primary keys.

Applied Black's 2026 stable style.

Refs #36769 -- Raised SuspiciousOperation for unexpected nested tags in XML Deserializer.

2026-01-12T21:38:32Z

Thanks Shai Berger and Natalia Bidart for reviews.

Fixed #36786 -- Fixed XML serialization of None values in natural keys.

2025-12-22T19:21:01Z

None values in natural keys were incorrectly serialized as the string "None", causing deserialization to fail for fields like UUIDField.

Fixed #27380 -- Added "raw" argument to m2m_changed signals.

2025-12-17T17:37:18Z

Fixed #35729 -- Enabled natural key serialization opt-out for subclasses.

2025-12-03T20:04:52Z

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. Co-authored-by: Jacob Walls

Fixed CVE-2025-64460 -- Corrected quadratic inner text accumulation in XML serializer.

2025-12-02T12:21:07Z

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.
