==================
- Don't fail trying to validate default value for Choice fields with
IContextSourceBinder object given as a source. See
https://bugs.launchpad.net/zope3/+bug/340416.
- Add an interface for ``DottedName`` field.
- Add ``vocabularyName`` attribute to the ``IChoice`` interface, change
"vocabulary" attribute description to be more sensible, making it
``zope.schema.Field`` instead of plain ``zope.interface.Attribute``.
- Make IBool interface of Bool more important than IFromUnicode so adapters
registered for IBool take precendence over adapters registered for
IFromUnicode.
