On behalf of all the contributors I am pleased to announce the release of
PyCA/cryptography (https://github.com/pyca/cryptography) 0.9!
Changelog:
* 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.
* Add support for the SECP256K1 elliptic curve.
* Fixed compilation when using an OpenSSL which was compiled with the no-comp
(OPENSSL_NO_COMP) option.
* Support DER serialization of public keys using the public_bytes method of
RSAPublicKeyWithSerialization, DSAPublicKeyWithSerialization, and
EllipticCurvePublicKeyWithSerialization.
* Support DER serialization of private keys using the private_bytes method of
RSAPrivateKeyWithSerialization, DSAPrivateKeyWithSerialization, and
EllipticCurvePrivateKeyWithSerialization.
* Add support for parsing X.509 certificate signing requests (CSRs) with
load_pem_x509_csr() and load_der_x509_csr().
* Moved cryptography.exceptions.InvalidToken to
cryptography.hazmat.primitives.twofactor.InvalidToken and deprecated the old
location. This was moved to minimize confusion between this exception and
cryptography.fernet.InvalidToken.
* Added support for X.509 extensions in Certificate objects. The following
extensions are supported as of this release:
- BasicConstraints
- AuthorityKeyIdentifier
- SubjectKeyIdentifier
- KeyUsage
- SubjectAlternativeName
- ExtendedKeyUsage
- CRLDistributionPoints
- AuthorityInformationAccess
- CertificatePolicies
Note that unsupported extensions with the critical flag raise
UnsupportedExtension while unsupported extensions set to non-critical are
silently ignored. Read the X.509 documentation for more information.

Master will be reopening for development of the tenth release shortly.
