+===============
+- Added MapReduce support

+- Deprecated fields' ``name`` parameter, replaced with ``db_field``
+- Added ``QuerySet.only`` for only retrieving specific fields
+- Added ``QuerySet.in_bulk()`` for bulk querying using ids
+- ``QuerySet``\ s now have a ``rewind()`` method, which is called automatically

+- Added ``GenericReferenceField``
+- Added ``get()`` and ``get_or_create()`` methods to ``QuerySet``

+  equal and documents are of same type)
+- ``QuerySet`` update methods now have an ``upsert`` parameter
+- Added field name substitution for Javascript code (allows the user to use the
+  Python names for fields in JS, which are later substituted for the real field
+  names)

+  dereferenced
+- ``ReferenceField``\ s may now be queried using their _id
+- Fixed bug where ``EmbeddedDocuments`` couldn't be non-polymorphic
