This release includes a number of bug-fixes and improvements, including:

* Improve documentation.
* Improved support defining models before calling
:meth:`~pymodm.connection.connect`.
* A field's :meth:`~pymodm.base.fields.MongoBaseField.to_python` method is no
longer called on every access. It is only called on the first access after a
call to :meth:`~pymodm.MongoModel.refresh_from_db` or, on the
first access after a field is set.
* Fixed bug when appending to an empty :class:`~pymodm.fields.ListField`.

-------------

This release fixes a couple problems from the previous 0.3 release and adds a
number of new features, including:

* Support for callable field defaults.
* Change default values for DictField, OrderedDictField, ListField, and
EmbeddedDocumentListField to be the empty value for their respective
containers instead of None.
* Add the `ignore_unknown_fields`
:ref:`metadata attribute <metadata-attributes>` which allows unknown
fields when parsing documents into a :class:`~pymodm.MongoModel`.
Note that with this option enabled, calling :meth:`~pymodm.MongoModel.save`
will erase these fields for that model instance.
* Add :meth:`pymodm.queryset.QuerySet.reverse`.
* Properly check that the `mongo_name` parameter to
:class:`~pymodm.base.fields.MongoBaseField`
and all keys in :class:`~pymodm.fields.DictField` and
:class:`~pymodm.fields.OrderedDictField` are valid MongoDB field names.
* Fix multiple issues in dereferencing fields thanks to
https://github.com/ilex.
