* Fixed macOS wheels to properly link against 1.1.0 rather than 1.0.2.
### 1.8
Added support for Python 3.6.
Windows and macOS wheels now link against OpenSSL 1.1.0.
macOS wheels are no longer universal. This change significantly shrinks the
size of the wheels. Users on macOS 32-bit Python (if there are any) should
migrate to 64-bit or build their own packages.
Changed ASN.1 dependency from pyasn1 to asn1crypto resulting in a
general performance increase when encoding/decoding ASN.1 structures. Also,
the pyasn1_modules test dependency is no longer required.

and
:func:~cryptography.hazmat.primitives.serialization.load_der_private_key
now require that password must be bytes if provided. Previously this
was documented but not enforced.
Added support for subgroup order in :doc:/hazmat/primitives/asymmetric/dh.
1.7.2
* Updated Windows and macOS wheels to be compiled against OpenSSL 1.0.2k.
### 1.7.1

will need to upgrade.
* Added support for Diffie-Hellman key exchange using
:meth:`~cryptography.hazmat.primitives.asymmetric.dh.DHPrivateKey.exchange`.
* The OS random engine for OpenSSL has been rewritten to improve compatibility
with embedded Python and other edge cases. More information about this change
can be found in the
`pull request <https://github.com/pyca/cryptography/pull/3229>`_.
### 1.6
Deprecated support for OpenSSL 1.0.0. Support will be removed in
cryptography 1.7.
Replaced the Python-based OpenSSL locking callbacks with a C version to fix
a potential deadlock that could occur if a garbage collection cycle occurred
while inside the lock.
Added support for :class:~cryptography.hazmat.primitives.hashes.BLAKE2b and
:class:~cryptography.hazmat.primitives.hashes.BLAKE2s when using OpenSSL
1.1.0.

:class:~cryptography.x509.Name.
:class:~cryptography.x509.DistributionPoint now accepts
:class:~cryptography.x509.RelativeDistinguishedName for
:attr:~cryptography.x509.DistributionPoint.relative_name.
Deprecated use of :class:~cryptography.x509.Name as
:attr:~cryptography.x509.DistributionPoint.relative_name.
:class:~cryptography.x509.Name now accepts an iterable of
:class:~cryptography.x509.RelativeDistinguishedName. RDNs can
be accessed via the :attr:~cryptography.x509.Name.rdns
attribute. When constructed with an iterable of
:class:~cryptography.x509.NameAttribute, each attribute becomes
a single-valued RDN.
Added support for signing and verifying RSA, DSA, and ECDSA signatures with
:class:~cryptography.hazmat.primitives.asymmetric.utils.Prehashed
digests.
1.5.3
* **SECURITY ISSUE**: Fixed a bug where ``HKDF`` would return an empty

### 1.2
BACKWARDS INCOMPATIBLE:
:class:~cryptography.x509.RevokedCertificate
:attr:~cryptography.x509.RevokedCertificate.extensions now uses extension
classes rather than returning raw values inside the
:class:~cryptography.x509.Extension
:attr:~cryptography.x509.Extension.value. The new classes
are:
:class:~cryptography.x509.CertificateIssuer
:class:~cryptography.x509.CRLReason
:class:~cryptography.x509.InvalidityDate
Deprecated support for OpenSSL 0.9.8 and 1.0.0. At this time there is no time
table for actually dropping support, however we strongly encourage all users
to upgrade, as those versions no longer receive support from the OpenSSL
project.

:meth:~cryptography.x509.CertificateRevocationList.extensions in the
OpenSSL backend. The following extensions are currently supported:
Added :class:~cryptography.x509.CertificateRevocationListBuilder and
:class:~cryptography.x509.RevokedCertificateBuilder to allow creation of
CRLs.
Unrecognized non-critical X.509 extensions are now parsed into an
:class:~cryptography.x509.UnrecognizedExtension object.

:class:`~cryptography.hazmat.primitives.asymmetric.ec.ECDH`.
* Added :class:`~cryptography.hazmat.primitives.kdf.x963kdf.X963KDF`.
* Added support for parsing certificate revocation lists (CRLs) using

and issuer distinguished names with the Certificate and CSR builder classes.
### 1.0.2
SECURITY ISSUE: The OpenSSL backend prior to 1.0.2 made extensive use
of assertions to check response codes where our tests could not trigger a
failure. However, when Python is run with -O these asserts are optimized
away. If a user ran Python with this flag and got an invalid response code
this could result in undefined behavior or worse. Accordingly, all response
checks from the OpenSSL backend have been converted from assert
to a true function call. Credit Emilia Käsper (Google Security Team)
for the report.
1.0.1
* We now ship OS X wheels that statically link OpenSSL by default. When
installing a wheel on OS X 10.10+ (and using a Python compiled against the
10.10 SDK) users will no longer need to compile. See :doc:`/installation` for
alternate installation methods if required.
* Set the default string mask to UTF-8 in the OpenSSL backend to resolve
character encoding issues with older versions of OpenSSL.
* Several new OpenSSL bindings have been added to support a future pyOpenSSL
release.
* Raise an error during install on PyPy < 2.6. 1.0+ requires PyPy 2.6+.
### 1.0
Switched to the new cffi_ set_source out-of-line API mode for
compilation. This results in significantly faster imports and lowered
memory consumption. Due to this change we no longer support PyPy releases
older than 2.6 nor do we support any released version of PyPy3 (until a
version supporting cffi 1.0 comes out).
Fix parsing of OpenSSH public keys that have spaces in comments.
Support serialization of certificate signing requests using the
public_bytes method of
:class:~cryptography.x509.CertificateSigningRequest.

provisioning URIs.
Add :class:~cryptography.hazmat.primitives.kdf.concatkdf.ConcatKDFHash
and :class:~cryptography.hazmat.primitives.kdf.concatkdf.ConcatKDFHMAC.

support for the same extensions supported in the CertificateBuilder.
Deprecate encode_rfc6979_signature and decode_rfc6979_signature in
favor of
:func:~cryptography.hazmat.primitives.asymmetric.utils.encode_dss_signature
and
:func:~cryptography.hazmat.primitives.asymmetric.utils.decode_dss_signature.
0.9.3
* Updated Windows wheels to be compiled against OpenSSL 1.0.2d.
### 0.9.2
Updated Windows wheels to be compiled against OpenSSL 1.0.2c.
0.9.1
* **SECURITY ISSUE**: Fixed a double free in the OpenSSL backend when using DSA
to verify signatures. Note that this only affects PyPy 2.6.0 and (presently
unreleased) CFFI versions greater than 1.1.0.
### 0.9
Removed support for Python 3.2. This version of Python is rarely used
and caused support headaches. Users affected by this should upgrade to 3.3+.
Deprecated support for Python 2.6. At the time there is no time table for
actually dropping support, however we strongly encourage all users to upgrade
their Python, as Python 2.6 no longer receives support from the Python core
team.

:func:~cryptography.x509.load_pem_x509_csr and
:func:~cryptography.x509.load_der_x509_csr.
Moved cryptography.exceptions.InvalidToken to
:class:cryptography.hazmat.primitives.twofactor.InvalidToken and deprecated
the old location. This was moved to minimize confusion between this exception
and :class:cryptography.fernet.InvalidToken.
Added support for X.509 extensions in :class:~cryptography.x509.Certificate
objects. The following extensions are supported as of this release:
Note that unsupported extensions with the critical flag raise
UnsupportedExtension while unsupported extensions set to non-critical are
silently ignored. Read the :doc:X.509 documentation</x509/index> for more
information.

:doc:X.509 documentation</x509/index> for more information.
0.6.1
* Updated Windows wheels to be compiled against OpenSSL 1.0.1j.
* Fixed an issue where OpenSSL 1.0.1j changed the errors returned by some
functions.
* Added our license file to the ``cryptography-vectors`` package.
* Implemented DSA hash truncation support (per FIPS 186-3) in the OpenSSL
backend. This works around an issue in 1.0.0, 1.0.0a, and 1.0.0b where
truncation was not implemented.

Added EllipticCurvePrivateKeyWithNumbers and
EllipticCurvePublicKeyWithNumbers support.
Work around three GCM related bugs in CommonCrypto and OpenSSL.
On the CommonCrypto backend adding AAD but not subsequently calling update
would return null tag bytes.
One the CommonCrypto backend a call to update without an empty add AAD call
would return null ciphertext bytes.
On the OpenSSL backend with certain versions adding AAD only would give
invalid tag bytes.
Support loading EC private keys from PEM.
0.5.4
* Added several functions to the OpenSSL bindings to support new
functionality in pyOpenSSL.

Updated Windows wheels to be compiled against OpenSSL 1.0.1i.
0.5.2
* Add ``TraditionalOpenSSLSerializationBackend`` support to ``multibackend``.
* Fix compilation error on OS X 10.8 (Mountain Lion).
### 0.5.1
Add PKCS8SerializationBackend support to multibackend.
0.5
* **BACKWARDS INCOMPATIBLE:**
:class:`~cryptography.hazmat.primitives.ciphers.modes.GCM` no longer allows
truncation of tags by default. Previous versions of ``cryptography`` allowed
tags to be truncated by default, applications wishing to preserve this
behavior (not recommended) can pass the ``min_tag_length`` argument.
* Windows builds now statically link OpenSSL by default. When installing a
wheel on Windows you no longer need to install OpenSSL separately. Windows
users can switch between static and dynamic linking with an environment
variable. See :doc:`/installation` for more details.
* Added :class:`~cryptography.hazmat.primitives.kdf.hkdf.HKDFExpand`.
* Added :class:`~cryptography.hazmat.primitives.ciphers.modes.CFB8` support
for :class:`~cryptography.hazmat.primitives.ciphers.algorithms.AES` and
:class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` on
``commoncrypto`` and :doc:`/hazmat/backends/openssl`.
* Added ``AES`` :class:`~cryptography.hazmat.primitives.ciphers.modes.CTR`
support to the OpenSSL backend when linked against 0.9.8.
* Added ``PKCS8SerializationBackend`` and
``TraditionalOpenSSLSerializationBackend`` support to the
:doc:`/hazmat/backends/openssl`.
* Added :doc:`/hazmat/primitives/asymmetric/ec` and
:class:`~cryptography.hazmat.backends.interfaces.EllipticCurveBackend`.
* Added :class:`~cryptography.hazmat.primitives.ciphers.modes.ECB` support
for :class:`~cryptography.hazmat.primitives.ciphers.algorithms.TripleDES` on
``commoncrypto`` and :doc:`/hazmat/backends/openssl`.
* Deprecated the concrete ``RSAPrivateKey`` class in favor of backend
specific providers of the
:class:`cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey`
interface.
* Deprecated the concrete ``RSAPublicKey`` in favor of backend specific
providers of the
:class:`cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`
interface.
* Deprecated the concrete ``DSAPrivateKey`` class in favor of backend
specific providers of the
:class:`cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey`
interface.
* Deprecated the concrete ``DSAPublicKey`` class in favor of backend specific
providers of the
:class:`cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey`
interface.
* Deprecated the concrete ``DSAParameters`` class in favor of backend specific
providers of the
:class:`cryptography.hazmat.primitives.asymmetric.dsa.DSAParameters`
interface.
* Deprecated ``encrypt_rsa``, ``decrypt_rsa``, ``create_rsa_signature_ctx`` and
``create_rsa_verification_ctx`` on
:class:`~cryptography.hazmat.backends.interfaces.RSABackend`.
* Deprecated ``create_dsa_signature_ctx`` and ``create_dsa_verification_ctx``
on :class:`~cryptography.hazmat.backends.interfaces.DSABackend`.
### 0.4
Deprecated salt_length on
:class:~cryptography.hazmat.primitives.asymmetric.padding.MGF1 and added it
to :class:~cryptography.hazmat.primitives.asymmetric.padding.PSS. It will
be removed from MGF1 in two releases per our :doc:/api-stability
policy.
Added decryption support to
:class:~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey
and encryption support to
:class:~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey.
Added signature support to
:class:~cryptography.hazmat.primitives.asymmetric.dsa.DSAPrivateKey
and verification support to
:class:~cryptography.hazmat.primitives.asymmetric.dsa.DSAPublicKey.
0.3
* Added :class:`~cryptography.hazmat.primitives.twofactor.hotp.HOTP`.
* Added :class:`~cryptography.hazmat.primitives.twofactor.totp.TOTP`.
* Added :class:`~cryptography.hazmat.primitives.ciphers.algorithms.IDEA`
support.
* Added signature support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPrivateKey`
and verification support to
:class:`~cryptography.hazmat.primitives.asymmetric.rsa.RSAPublicKey`.
* Moved test vectors to the new ``cryptography_vectors`` package.
### 0.2.2
Removed a constant definition that was causing compilation problems with
specific versions of OpenSSL.
0.2.1
* Fix a bug where importing cryptography from multiple paths could cause
initialization to fail.
### 0.2
Added commoncrypto.
Added initial commoncrypto.
Removed register_cipher_adapter method from
:class:~cryptography.hazmat.backends.interfaces.CipherBackend.
Added support for the OpenSSL backend under Windows.
Improved thread-safety for the OpenSSL backend.
Fixed compilation on systems where OpenSSL's ec.h header is not
available, such as CentOS.
cryptography is not pinned to a specific version.
I'm pinning it to the latest version 1.8.2 for now.
