appropriate value at the beginning of each request, or disable persistent
connections.
``BooleanField`` no longer defaults to ``False``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When a :class:`~django.db.models.BooleanField` doesn't have an explicit
:attr:`~django.db.models.Field.default`, the implicit default value is
``None``. In previous version of Django, it was ``False``, but that didn't
represent accurantely the lack of a value.
Code that relies on the default value being ``False`` may raise an exception
when saving new model instances to the database, because ``None`` isn't an
acceptable value for a :class:`~django.db.models.BooleanField`. You should
either specify ``default=False`` explicitly on the field definition, or ensure
the field is set to ``True`` or ``False`` before saving the object.
