Marshmallow

++++++++++++++++++

* Fix bug with serializing dictionaries.
* Fix error raised when serializing empty list.
* Add ``only`` and ``exclude`` parameters to Serializer constructor.
* Add ``strict`` parameter and option: causes Serializer to raise an error if invalid data are passed in, rather than storing errors.
* Updated Flask + SQLA example in docs.

++++++++++++++++++

* Declaring Serializers just got easier. The ``class Meta`` paradigm allows you to specify fields more concisely. Can specify ``fields`` and ``exclude`` options.
* Allow date formats to be changed by passing ``format`` parameter to ``DateTime`` field constructor. Can either be ``"rfc"`` (default), ``"iso"``, or a date format string.
* More useful error message when declaring fields as classes (instead of an instance, which is the correct usage).
* Rename ``MarshallingException`` -> ``MarshallingError``.
* Rename ``marshmallow.core`` -> ``marshmallow.serializer``.

++++++++++++++++++

* Allow prefixing field names.
* Fix storing errors on Nested Serializers.
* Python 2.6 support.
