Greetings fellow Pythoneers,

I'm happy to announce that pyOpenSSL 0.14 is now available.

pyOpenSSL is a set of Python bindings for OpenSSL.  It includes some =

low-level cryptography APIs but is primarily focused on providing an API =

for using the TLS protocol from Python.

Check out the PyPI page (<https://pypi.python.org/pypi/pyOpenSSL>) for =

downloads.

This release of pyOpenSSL adds:

* Support for TLSv1.1 and TLSv1.2

* First-class support for PyPy

* New flags, such as MODE_RELEASE_BUFFERS and OP_NO_COMPRESSION

* Some APIs to access to the SSL session cache

* A variety of bug fixes for error handling cases

Additionally, there are three major changes to the project:

First, the documentation has been converted from LaTeX (CPython's =

previous documentation system) to Sphinx (CPython's "new" documentation =

system ;).  You can find the new documentation on the PyPI documentation =

site (<https://pythonhosted.org/pyOpenSSL/>) or =

<https://pyopenssl.readthedocs.org/>).

Second, pyOpenSSL is no longer implemented in C as a collection of =

extension modules using the Python/C API. Instead, pyOpenSSL is now a =

pure-Python project with a dependency on a new project, cryptography =

(<https://github.com/pyca/cryptography>), which provides (among other =

things) a cffi-based interface to OpenSSL.

This change means that pyOpenSSL development is now more accessible to =

Python programmers with little or no experience with C. This is also how =

pyOpenSSL is now able to support PyPy.

Finally, the project's code hosting has moved from Launchpad to Github. =

Many branches remain only on Launchpad along with their associated bug =

reports. Over the coming releases I hope that the fixes and features in =

these branches will be ported to Python and incorporated into the =

pyOpenSSL master development branch. Bug tracking has been disabled on =

Launchpad so that the amount of useful information hosted there can =

gradually dwindle to nothing. Please use Github =

(<https://github.com/pyca/pyopenssl>) for further development and bug =

reporting.

Thanks and enjoy,
Jean-Paul
