-5.1 (unreleased)
-================
+5.0.1 (unreleased)
+==================
 
-- Nothing changed yet.
+- Fix: add ``Text.unicode_normalization = 'NFC'`` as default, because some are
+  persisting schema fields. Setting that attribute only in ``__init__``
+  breaks loading old objects.

#87 breaks persistent Text fields
We persist some schemas that use fields. Setting `unicode_normalization` in `Text.__init__` breaks persistent loading of such schemas.
