Log message:
py-ZopeSchema: updated to 6.0.0

6.0.0:
Require zope.interface 5.0.
Ensure the resolution orders of all fields are consistent and make sense. In \ 
particular, Bool fields now correctly implement IBool before IFromUnicode.
Add support for Python 3.8.
Drop support for Python 3.4.

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.

5.0:
Set IDecimal attributes min, max and default as Decimal type instead of Number.
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.

py-ZopeSchema: updated to 4.9.3

4.9.3:
- Fixed a ReST error in getDoc() results when having "subfields"
  with titles.

4.9.2:
- Make sure that the title for IObject.validate_invariants is a unicode
  string.

4.9.1:
- Fix SimpleTerm token for non-ASCII bytes values.

4.9.0:
- Make NativeString and NativeStringLine distinct types that
  implement the newly-distinct interfaces INativeString and
  INativeStringLine. Previously these were just aliases for either
  Text (on Python 3) or Bytes (on Python 2).
- Fix Field.getDoc() when value_type or key_type is
  present. Previously it could produce ReST that generated Sphinx
  warnings.
- Make DottedName accept leading underscores for each segment.
- Add PythonIdentifier, which accepts one segment of a dotted
  name, e.g., a python variable or class.

4.8.0:
- Add the interface IFromBytes, which is implemented by the
  numeric and bytes fields, as well as URI, DottedName, and
  Id.
- Fix passing None as the description to a field constructor.

Log message:
py-ZopeSchema: update to 4.5.0

4.5.0:
- Drop support for Python 2.6, 3.2, and 3.3.
- Add support for Python 3.5 and 3.6.
- Drop support for 'setup.py test'. Use zope.testrunner instead.

Log message:
Import zope.schema 4.4.2 as devel/py-ZopeSchema.

Zope Interface extension for defining data schemas. Schemas extend
the notion of interfaces to detailed descriptions of Attributes
(but not methods).
