**********************
* Rename ``gpgliblib.gnupg.GnuPGBackend`` to
:py:class:`gpgliblib.python_gnupg.PythonGnupgBackend` for consistency and to
avoid confusion with its fork, `gnupg <http://pythonhosted.org/gnupg/>`_.
* New backend for `pyme <https://pypi.python.org/pypi/pyme3>`_,
:py:class:`gpgliblib.pyme.PymeBackend`.
* Backends now support the ``gnupg_version`` parameter to manually override the
version of gnupg being used.
* Support for exporting keys via :py:func:`gpgliblib.base.GpgKey.export`.
* Support for deleting keys via :py:func:`gpgliblib.base.GpgKey.delete`.
* Add new attributes for GPG keys:
* :py:attr:`gpgliblib.base.GpgKey.has_secret_key`
* :py:attr:`gpgliblib.base.GpgKey.keyid` and
:py:attr:`gpgliblib.base.GpgKey.long_keyid`
* Support for generating testcoverage reports via ``fab coverage``.
