Fixed #17063 -- Fixed visibility of a few version-dependant notes in our documentation.

.. versionchanged:: 1.4

    In addition, these views also return

    :class:`~django.template.response.TemplateResponse`

    instances which allow you to easily customize the response data before

:class:`NullBooleanField` instead.

.. versionchanged:: 1.2

    In previous versions of Django when running under MySQL ``BooleanFields``

    would return their data as ``ints``, instead of true ``bools``.  See the

    release notes for a complete description of the change.

A :class:`CharField` for a URL. Has one extra optional argument:

.. deprecated:: 1.4

   ``verify_exists`` is deprecated for security reasons as of 1.4 and will be

   removed in Django 1.5. Prior to 1.3.1, the default value was ``True``.

.. currentmodule:: django.contrib.auth.utils

.. versionadded:: 1.4

    The :mod:`django.contrib.auth.utils` module provides a set of functions

    to create and validate hashed password. You can use them independently

    from the ``User`` model.

   .. _`Keyword Arguments`: http://docs.python.org/tutorial/controlflow.html#keyword-arguments

.. versionchanged:: 1.4

    The field specified in a lookup has to be the name of a model field.

    There's one exception though, in case of a

    :class:`~django.db.models.fields.ForeignKey` you can specify the field

dynamically.

.. versionadded:: 1.4

    Django also allows to translate URLs according to the active language.

    This process is described in the

    :ref:`internationalization docs <url-internationalization>`.
