==================
- Add support for Python 3.8.
- Depend on zope.interface 5.0.
- Update the datrie dependency. See https://github.com/NextThought/nti.contentfragments/issues/24
- Make ``IUnicodeContentFragment`` extend
``zope.interface.common.collections.ISequence`` instead of the
semi-deprecated ``zope.interface.common.sequence.IReadSequence``.
- Replace custom interfaces ``IString``, ``IUnicode`` and ``IBytes``
with aliases for ``INativeString``, ``ITextString`` and
``IByteString`` from ``zope.interface.common.builtins``. These
custom aliases are now deprecated. See https://github.com/NextThought/nti.contentfragments/issues/23.
- Fix unicode normalization breaking schema fields with zope.schema
6.0. See https://github.com/NextThought/nti.contentfragments/issues/26
- Ensure all objects have consistent resolution orders.
