+.. warning::
+    This release is NOT backwards compatable with v0.2.3. Specifically we have
+    removed the ``get_parent()``, ``get_children()``, and
+    ``get_sentence_generator()`` functions from the classes inhereting from
+    Context in the data model.

 * `@lukehsiao`_: Organize documentation for lf_helpers by modality.
