@@ -9,6 +9,12 @@ Changelog
* **BACKWARDS INCOMPATIBLE:** ``Whirlpool``, ``RIPEMD160``, and
``UnsupportedExtension`` have been removed in accordance with our
:doc:`/api-stability` policy.
+* Deprecated passing unicode to the :class:`~cryptography.x509.DNSName`
+ constructor. Instead, users should pass DNS names as ``bytes``, with ``idna``
+ encoding if necessary. In addition, the
+ :attr:`~cryptography.x509.DNSName.value` attribute was deprecated, users
+ should use :attr:`~cryptography.x509.DNSName.bytes_value` to access the
+ raw DNS name.
