Django 3.0.3 fixes a security issue and several bugs in 3.0.2.
StringAgg(delimiter)¶StringAgg aggregation function was
subject to SQL injection, using a suitably crafted delimiter.
Fixed a regression in Django 3.0 that caused a crash when subtracting
DateField, DateTimeField, or TimeField from a Subquery()
annotation (#31133).

values_list() crashed if a queryset contained an aggregation and
Exists() annotation (#31136).
Relaxed the system check added in Django 3.0 to reallow use of a sublanguage
in the LANGUAGE_CODE setting, when a base language is available in
Django but the sublanguage is not (#31141).

IntegerChoices, and Choices in templates (#31154).

Fixed a regression in Django 2.2 that caused a crash of
ArrayAgg and
StringAgg with filter
argument when used in a Subquery (#31097).
Fixed a regression in Django 2.2.7 that caused
get_FOO_display() to work incorrectly when
overriding inherited choices (#31124).

QuerySet.prefetch_related() for GenericForeignKey with a custom
ContentType foreign key (#31190).
