39.0.1 - 2023-02-07

* **SECURITY ISSUE** - Fixed a bug where ``Cipher.update_into`` accepted Python
  buffer protocol objects, but allowed immutable buffers. **CVE-2023-23931**
* Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.0.8.

39.0.0 - 2023-01-01

• BACKWARDS INCOMPATIBLE: Support for OpenSSL 1.1.0 has been removed. Users on older version of OpenSSL will need to upgrade.
• BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL < 3.5. The new minimum LibreSSL version is 3.5.0. Going forward our policy is to support versions of LibreSSL that are available in versions of OpenBSD that are still receiving security support.
• BACKWARDS INCOMPATIBLE: Removed the encode_point and from_encoded_point methods on :class:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicNumbers, which had been deprecated for several years. :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.public_bytes and :meth:~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.from_encoded_point should be used instead.
• BACKWARDS INCOMPATIBLE: Support for using MD5 or SHA1 in :class:~cryptography.x509.CertificateBuilder, other X.509 builders, and PKCS7 has been removed.
• BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.10 and 10.11, macOS users must upgrade to 10.12 or newer.
• ANNOUNCEMENT: The next version of cryptography (40.0) will change the way we link OpenSSL. This will only impact users who build cryptography from source (i.e., not from a wheel), and specify their own version of OpenSSL. For those users, the CFLAGS, LDFLAGS, INCLUDE, LIB, and CRYPTOGRAPHY_SUPPRESS_LINK_FLAGS environment variables will no longer be respected. Instead, users will need to configure their builds as documented here_.
• Added support for :ref:disabling the legacy provider in OpenSSL 3.0.x<legacy-provider>.
• Added support for disabling RSA key validation checks when loading RSA keys via :func:~cryptography.hazmat.primitives.serialization.load_pem_private_key, :func:~cryptography.hazmat.primitives.serialization.load_der_private_key, and :meth:~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateNumbers.private_key. This speeds up key loading but is :term:unsafe if you are loading potentially attacker supplied keys.
• Significantly improved performance for :class:~cryptography.hazmat.primitives.ciphers.aead.ChaCha20Poly1305
