[1.2.X] Added note to 1.2.5 release notes about ModelAdmin.lookup_allowed change

should either insert it using :ref:`test fixtures

<topics-testing-fixtures>`, or using the ``setUp()`` method of your

test case.

ModelAdmin.lookup_allowed signature changed

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Django 1.2.4 introduced a method ``lookup_allowed`` on ``ModelAdmin``, to cope

with a security issue (changeset `[15033]

<http://code.djangoproject.com/changeset/15033>`_). Although this method was

never documented, it seems some people have overridden ``lookup_allowed``,

especially to cope with regressions introduced by that changeset. While the

method is still undocumented and not marked as stable, it may be helpful to know

that the signature of this function has changed.
