Mentionned changes from r17056 in the release notes.

deprecated; ``execute_from_command_line`` can be used instead. (Neither of

these functions is documented public API, but a deprecation path is needed due

to use in existing ``manage.py`` files.)

``is_safe`` and ``needs_autoescape`` attributes of template filters

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

Two flags, ``is_safe`` and ``needs_autoescape``, define how each template filter

interacts with Django's auto-escaping behavior. They used to be attributes of

the filter function::

    @register.filter

    def noop(value):

        return value

    noop.is_safe = True

However, this technique caused some problems in combination with decorators,

especially :func:`@stringfilter <django.template.defaultfilters.stringfilter>`.

Now, the flags are keyword arguments of :meth:`@register.filter

<django.template.Library.filter>`::

    @register.filter(is_safe=True)

    def noop(value):

        return value
