Update to 1.0:

1.0 - 2015-08-12
~~~~~~~~~~~~~~~~

* 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`.
* Support serialization of certificates using the ``public_bytes`` method of
  :class:`~cryptography.x509.Certificate`.
* Add ``get_provisioning_uri`` method to
  :class:`~cryptography.hazmat.primitives.twofactor.hotp.HOTP` and
  :class:`~cryptography.hazmat.primitives.twofactor.totp.TOTP` for generating
  provisioning URIs.
* Add :class:`~cryptography.hazmat.primitives.kdf.concatkdf.ConcatKDFHash`
  and :class:`~cryptography.hazmat.primitives.kdf.concatkdf.ConcatKDFHMAC`.
* Raise a ``TypeError`` when passing objects that are not text as the value to
  :class:`~cryptography.x509.NameAttribute`.
* Add support for :class:`~cryptography.x509.OtherName` as a general name
  type.
* Added new X.509 extension support in :class:`~cryptography.x509.Certificate`
  The following new extensions are now supported:

  * :class:`~cryptography.x509.OCSPNoCheck`
  * :class:`~cryptography.x509.InhibitAnyPolicy`
  * :class:`~cryptography.x509.IssuerAlternativeName`
  * :class:`~cryptography.x509.NameConstraints`

* Extension support was added to
  :class:`~cryptography.x509.CertificateSigningRequest`.
* Add support for creating signed certificates with
  :class:`~cryptography.x509.CertificateBuilder`. This includes support for
  the following extensions:

  * :class:`~cryptography.x509.BasicConstraints`
  * :class:`~cryptography.x509.SubjectAlternativeName`
  * :class:`~cryptography.x509.KeyUsage`
  * :class:`~cryptography.x509.ExtendedKeyUsage`
  * :class:`~cryptography.x509.SubjectKeyIdentifier`
  * :class:`~cryptography.x509.AuthorityKeyIdentifier`
  * :class:`~cryptography.x509.AuthorityInformationAccess`
  * :class:`~cryptography.x509.CRLDistributionPoints`
  * :class:`~cryptography.x509.InhibitAnyPolicy`
  * :class:`~cryptography.x509.IssuerAlternativeName`
  * :class:`~cryptography.x509.OCSPNoCheck`

* Add support for creating certificate signing requests with
  :class:`~cryptography.x509.CertificateSigningRequestBuilder`. This includes
  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`.
