+:pep:`466` related features added in Python 2.7.9:
+
+* Most of Python 3.4's :mod:`ssl` module was backported. This means :mod:`ssl`
+  now supports Server Name Indication, TLS1.x settings, access to the platform
+  certificate store, the :class:`~ssl.SSLContext` class, and other
+  features. (Contributed by Alex Gaynor and David Reid in :issue:`21308`.)
+
+* :func:`os.urandomn` was changed to cache a file descriptor to ``/dev/urandom``
+  instead of reopening ``/dev/urandom`` on every call. (Contributed by Alex
+  Gaynor in :issue:`21305`.)
