- update to 39.0.0:
* **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.
* **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 disabling the legacy provider in OpenSSL 3.0.x
* Added support for disabling RSA key validation checks when loading RSA
keys via
~cryptography.hazmat.primitives.serialization.load_pem_private_key
