-------------------
+1.1 - unreleased
+----------------
+
+* Provide a version of the RichText field schema for use with
+  plone.schemaeditor. Only the ``default_mime_type`` field is exposed for
+  editing through-the-web, with a vocabulary of mimetypes derived from
+  the ``AllowedContentTypes`` vocabulary in ``plone.app.vocabularies``
+  (which can be adjusted via Plone's markup control panel).
