<commit_before>Changelog
=========

1.0 - `master`_
~~~~~~~~~~~~~~~~

.. note:: This version is not yet released and is under active development.

* Switched to the new `cffi`_ ``set_source`` out-of-line API mode for
  compilation. This results in significantly faster imports and lowered
  memory consumption.
* 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.

0.9.1 - 2015-06-06
~~~~~~~~~~~~~~~~~~

* **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 - 2015-05-13
~~~~~~~~~~~~~~~~

* 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<commit_msg>add some info about pypy version support with cffi 1.0+<commit_after>Changelog

* 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).

  ``public_bytes`` method of
