    origins. If you need the previous behavior, explicitly set
    :setting:`SECURE_REFERRER_POLICY` to ``None``.
  
  * The default :class:`django.core.signing.Signer` algorithm is changed to the
    SHA-256. Support for signatures made with the old SHA-1 algorithm remains
    until Django 4.0.
  
    Also, the new ``algorithm`` parameter of the
    :class:`~django.core.signing.Signer` allows customizing the hashing
    algorithm.
