Description (last modified by Jacob Walls)

The end of support for MariaDB 10.6 is 6 July 2026. Therefore, Django 6.1 (released in August 2026) may set MariaDB 10.11 as the minimum version that it supports (see SupportedDatabaseVersions).

The uuid datatype was introduced in 10.7. If we prioritize dropping this support (scheduled anyway) then we can avoid tinkering with the test altered in 0174a85770356fd12e4c8daa42a4f1c752ae00e6 that produces this failure:

django.db.utils.OperationalError: (1901, "Function or expression 'cast(`field` as char(32) charset utf8mb4)' cannot be used in the GENERATED ALWAYS AS clause of `field_copy`")

for this model:

class GeneratedModelFieldWithConverters(models.Model):
    field = models.UUIDField()
    field_copy = models.GeneratedField(
        expression=Cast("field", models.UUIDField()),
        output_field=models.UUIDField(),
        db_persist=True,
    )

It took me a moment to understand why dropping from 10.6 up to 10.11 but it seems that's the cadence published by MariaDB.
