2.1:
FINAL DEPRECATION Python 2.6 support is deprecated, and will be removed in the \ 
next release of cryptography.
BACKWARDS INCOMPATIBLE: Whirlpool, RIPEMD160, and UnsupportedExtension have been \ 
removed in accordance with our :doc:`/api-stability` policy.
BACKWARDS INCOMPATIBLE: :attr:`~cryptography.x509.DNSName.value`, \ 
:attr:`~cryptography.x509.RFC822Name.value`, and \ 
:attr:`~cryptography.x509.UniformResourceIdentifier.value` will now return an \ 
:term:`A-label` string when parsing a certificate containing an \ 
internationalized domain name (IDN) or if the caller passed a :term:`U-label` to \ 
the constructor. See below for additional deprecations related to this change.
Installing cryptography now requires pip 6 or newer.
Deprecated passing :term:`U-label` strings to the \ 
:class:`~cryptography.x509.DNSName`, \ 
:class:`~cryptography.x509.UniformResourceIdentifier`, and \ 
:class:`~cryptography.x509.RFC822Name` constructors. Instead, users should pass \ 
values as :term:`A-label` strings with idna encoding if necessary. This change \ 
will not affect anyone who is not processing internationalized domains.
Added support for \ 
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.ChaCha20`. In most \ 
cases users should choose \ 
:class:`~cryptography.hazmat.primitives.ciphers.aead.ChaCha20Poly1305` rather \ 
than using this unauthenticated form.
Added :meth:`~cryptography.x509.CertificateRevocationList.is_signature_valid` to \ 
:class:`~cryptography.x509.CertificateRevocationList`.
Support :class:`~cryptography.hazmat.primitives.hashes.BLAKE2b` and \ 
:class:`~cryptography.hazmat.primitives.hashes.BLAKE2s` with \ 
:class:`~cryptography.hazmat.primitives.hmac.HMAC`.
Added support for :class:`~cryptography.hazmat.primitives.ciphers.modes.XTS` \ 
mode for AES.
Added support for using labels with \ 
:class:`~cryptography.hazmat.primitives.asymmetric.padding.OAEP` when using \ 
OpenSSL 1.0.2 or greater.
Improved compatibility with NSS when issuing certificates from an issuer that \ 
has a subject with non-UTF8String string types.
Add support for the :class:`~cryptography.x509.DeltaCRLIndicator` extension.
Add support for the :class:`~cryptography.x509.TLSFeature` extension. This is \ 
commonly used for enabling OCSP Must-Staple in certificates.
Add support for the :class:`~cryptography.x509.FreshestCRL` extension.

Log message:
2.0.3:
Fixed an issue with weak linking symbols when compiling on macOS versions older \ 
than 10.12.

Log message:
2.0.2:
Marked all symbols as hidden in the manylinux1 wheel to avoid a bug with symbol \ 
resolution in certain scenarios.

2.0.1:
Fixed a compilation bug affecting OpenBSD.
Altered the manylinux1 wheels to statically link OpenSSL instead of dynamically \ 
linking and bundling the shared object. This should resolve crashes seen when \ 
using uwsgi or other binaries that link against OpenSSL independently.
Fixed the stack level for the signer and verifier warnings.

Log message:
2.0:

BACKWARDS INCOMPATIBLE: Support for Python 3.3 has been dropped.
We now ship manylinux1 wheels linked against OpenSSL 1.1.0f. These wheels will \ 
be automatically used with most Linux distributions if you are running the \ 
latest pip.
Deprecated the use of signer on \ 
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey`, \ 
:class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey`, and \ 
:class:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey` \ 
in favor of sign.
Deprecated the use of verifier on \ 
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`, \ 
:class:`~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey`, and \ 
:class:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey` in \ 
favor of verify.
Added support for parsing \ 
:class:`~cryptography.x509.certificate_transparency.SignedCertificateTimestamp` \ 
objects from X.509 certificate extensions.
Added support for \ 
:class:`~cryptography.hazmat.primitives.ciphers.aead.ChaCha20Poly1305`.
Added support for :class:`~cryptography.hazmat.primitives.ciphers.aead.AESCCM`.
Added :class:`~cryptography.hazmat.primitives.ciphers.aead.AESGCM`, a "one \ 
shot" API for AES GCM encryption.
Added support for :doc:`/hazmat/primitives/asymmetric/x25519`.
Added support for serializing and deserializing Diffie-Hellman parameters with \ 
:func:`~cryptography.hazmat.primitives.serialization.load_pem_parameters`, \ 
:func:`~cryptography.hazmat.primitives.serialization.load_der_parameters`, and \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.dh.DHParameters.parameter_bytes` \ 
.
The extensions attribute on :class:`~cryptography.x509.Certificate`, \ 
:class:`~cryptography.x509.CertificateSigningRequest`, \ 
:class:`~cryptography.x509.CertificateRevocationList`, and \ 
:class:`~cryptography.x509.RevokedCertificate` now caches the computed \ 
Extensions object. There should be no performance change, just a performance \ 
improvement for programs accessing the extensions attribute multiple times.

Log message:
Changes 1.9:

BACKWARDS INCOMPATIBLE: Elliptic Curve signature verification no longer returns \ 
True on success. This brings it in line with the interface's documentation, and \ 
our intent. The correct way to use \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.verify` \ 
has always been to check whether or not \ 
:class:`~cryptography.exceptions.InvalidSignature` was raised.
BACKWARDS INCOMPATIBLE: Dropped support for macOS 10.7 and 10.8.
BACKWARDS INCOMPATIBLE: The minimum supported PyPy version is now 5.3.
Python 3.3 support has been deprecated, and will be removed in the next \ 
cryptography release.
Add support for providing tag during \ 
:class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` finalization via \ 
:meth:`~cryptography.hazmat.primitives.ciphers.AEADDecryptionContext.finalize_with_tag`.
Fixed an issue preventing cryptography from compiling against LibreSSL 2.5.x.
Added \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePublicKey.key_size` \ 
and \ 
:meth:`~cryptography.hazmat.primitives.asymmetric.ec.EllipticCurvePrivateKey.key_size` \ 
as convenience methods for determining the bit size of a secret scalar for the \ 
curve.
Accessing an unrecognized extension marked critical on an X.509 object will no \ 
longer raise an UnsupportedExtension exception, instead an \ 
:class:`~cryptography.x509.UnrecognizedExtension` object will be returned. This \ 
behavior was based on a poor reading of the RFC, unknown critical extensions \ 
only need to be rejected on certificate verification.
The CommonCrypto backend has been removed.
MultiBackend has been removed.
Whirlpool and RIPEMD160 have been deprecated.
