What's new in Django 1.4
Django 1.4 now includes a :meth:`QuerySet.select_for_update()
<django.db.models.query.QuerySet.select_for_update>` method which generates a
``SELECT ... FOR UPDATE`` SQL query. This will lock rows until the end of the
transaction, meaning that other transactions cannot modify or delete rows
matched by a ``FOR UPDATE`` query.
For more details, see the documentation for
.. _backwards-incompatible-changes-1.4:
Backwards incompatible changes in 1.4
