Zope-index

==================

- Drop support for Python 3.3.

- Docs are now hosted at https://zopeindex.readthedocs.io/

- Drop support for ``setup.py test``.

- Remove some internal test scripts that were never ported to Python 3.

- Reach and maintain 100% test coverage.

==================

- ``None`` are now valid values in a field index. This requires BTrees
>= 4.4.1.
- Allow ``TypeError`` to propagate from a field index when the value
cannot be stored in a BTree. Previously it was silently ignored
because it was expected that these were usually ``None``.
- Add support for Python 3.6. See `issue 8
<https://github.com/zopefoundation/zope.index/issues/8>`_.
- Make the C implementation of the text index's score function
(``zope.text.index.okascore``) importable under Python 3. Previously
we would fall back to a pure-Python implementation. See `issue 14
<https://github.com/zopefoundation/zope.index/issues/14>`_.
- Packaging: Distribute ``manylinux`` wheels and Windows wheels.

==================

- Drop support for Python 2.6.

- Add support for Python 3.5.

==================

- Add support for PyPy. (PyPy3 is pending release of a fix for:
https://bitbucket.org/pypy/pypy/issue/1946)

- Add support for Python 3.4.

- Add support for testing on Travis.

==================

- Add the forgotten dependency on ``six``.
Fixes https://github.com/zopefoundation/zope.index/issues/1.

==================

- Add support for Python 3.3.

- Replace deprecated ``zope.interface.implements`` usage with equivalent
``zope.interface.implementer`` decorator.

- Drop support for Python 2.4 and 2.5.
