- update to version 5.0.1
- Fix: add ``Text.unicode_normalization = 'NFC'`` as default, because some are
persisting schema fields. Setting that attribute only in ``__init__``
breaks loading old objects.
- Set ``IDecimal`` attributes ``min``, ``max`` and ``default`` as ``Decimal``
type instead of ``Number``.
See `issue 88 `_.
- Enable unicode normalization for ``Text`` fields.
The default is NFC normalization. Valid forms are 'NFC', 'NFKC', 'NFD', and
'NFKD'. To disable normalization, set ``unicode_normalization`` to ``False``
or ``None`` when calling ``__init__`` of the ``Text`` field.
