~~~~~~~~
* :setting:`X_FRAME_OPTIONS` now defaults to ``'DENY'``. In older versions, the
:setting:`X_FRAME_OPTIONS` setting defaults to ``'SAMEORIGIN'``. If your site
uses frames of itself, you will need to explicitly set ``X_FRAME_ORIGINS =
'SAMEORIGIN'`` for them to continue working.
* :setting:`SECURE_CONTENT_TYPE_NOSNIFF` setting now defaults to ``True``. With
the enabled :setting:`SECURE_CONTENT_TYPE_NOSNIFF`, the

In older versions, the :setting:`X_FRAME_OPTIONS` setting defaults to
``'SAMEORIGIN'``. To make Django projects more secure by default,
:setting:`X_FRAME_OPTIONS` now defaults to ``'DENY'``. If your site uses frames

more secure default values:

* :setting:`SECURE_CONTENT_TYPE_NOSNIFF` now defaults to ``True``.
