+``DEFAULT_AUTO_FIELD`` setting now defaults to ``BigAutoField``
+---------------------------------------------------------------
+
+Since Django 3.2 when the :setting:`DEFAULT_AUTO_FIELD` setting was added,
+the default :djadmin:`startproject` template's ``settings.py`` contained::
+
+    DEFAULT_AUTO_FIELD = "django.db.models.BigAutoField"
+
+and the default :djadmin:`startapp` template's ``AppConfig`` contained::
+
+    default_auto_field = "django.db.models.BigAutoField"
+
+At that time, the default value of :setting:`DEFAULT_AUTO_FIELD` remained
+:class:`django.db.models.AutoField` for backwards compatibility.
+
+In Django 6.0, :setting:`DEFAULT_AUTO_FIELD` now defaults to
+:class:`django.db.models.BigAutoField` and the aforementioned lines in the
+project and app templates are removed.
+
+Most projects shouldn't be affected since there has been a system check warning
+since Django 3.2 if a project doesn't set :setting:`DEFAULT_AUTO_FIELD`:
+
+    **models.W042**: Auto-created primary key used when not defining a primary
+    key type, by default ``django.db.models.AutoField``.
+
+If you haven't dealt with this warning by now, add
+``DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'`` to your project's
+settings, or ``default_auto_field = 'django.db.models.AutoField'`` to an app's
+``AppConfig``, as needed.
+
 Custom ORM expressions should return params as a tuple
