==================
- Added a ``bcrypt``-based password manager (available only if the
`bcrypt <https://pypi.python.org/pypi/bcrypt>`_ library is
importable). This manager can also check passwords that were encoded
with `z3c.bcrypt <https://pypi.python.org/pypi/z3c.bcrypt>`_. If
that package is *not* installed, then ``configure.zcml`` will
install this manager as a utility with both the ``BCRYPT``
(preferred) and ``bcrypt`` names for compatibility with it. (See
https://github.com/zopefoundation/zope.password/issues/10)
- Add a ``bcrypt_kdf`` password manager. This allows tunable numbers
of rounds. See https://github.com/zopefoundation/zope.password/issues/9
- Fix the ``zpasswd`` console script on Python 3.
- Update the ``zpasswd`` script to use ``argparse`` instead of ``optparse.``
- Use ``hmac.compare_digest`` when checking passwords to
prevent timing analysis. This requires Python 2.7.7 or above.
- Add support for Python 3.6.
- Drop support for Python 3.3 and Python 2.7.6 and below.
- Drop support for ``python setup.py test``.
