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 #34779 -- Avoided unnecessary selection of non-nullable m2m fields without natural keys during serialization.

2023-08-19T08:29:43Z

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 f9936deed1ff13b20e18bd9ca2b0750b52706b6c.

Fixed #34620 -- Fixed serialization crash on m2m fields without natural keys when base querysets use select_related().

Regression in 19e0587ee596debf77540d6a08ccb6507e60b6a7. Thanks Martin Svoboda for the report.
