+Several structs have also been rewritten to subclass GObject like
+GMimeContentType and GMimeContentDisposition as well as
+InternetAddress and InternetAddressList.

+Not only have InternetAddress and InternetAddressList been ported to
+GObject, but they have also undergone other design

+All functions that return a GObject have been changed to not add a ref
+to the object returned, meaning that it is no longer necessary to call
+g_object_unref() on MIME parts returned from functions like
+g_mime_message_get_mime_part() or g_mime_multipart_get_part(). This
+was done to be more consistent with the Gtk+ API.
