 * New features and changes:
 
+  - Added support for Python 3.1 and 3.2.
+  - Adapt types 'bytearray' (from Python 2.6) and 'memoryview' (from Python
+    2.7) to bytea data type.
   - Added `register_composite()` function to cast PostgreSQL composite types
     into Python tuples/namedtuples.
   - More efficient iteration on named cursors.

-- Binary types: Python types such as `!bytes`, `!bytearray`, `!buffer`,

+- Binary types: Python types representing binary objects are converted in
+  PostgreSQL binary string syntax, suitable for :sql:`bytea` fields.   Such
+  types are `!buffer` (only available in Python 2), `!memoryview` (available
+  from Python 2.7), `!bytearray` (available from Python 2.6) and `!bytes`
+  (only form Python 3: the name is available from Python 2.6 but it's only an
+  alias for the type `!str`).  Received data is returned as `!buffer` (in
+  Python 2) or `!memoryview` (in Python 3).
+
+  .. note::
+
+    In Python 2, if you have binary data in a `!str` object, you can pass them
+    to a :sql:`bytea` field using the `psycopg2.Binary` wrapper::
+
+        mypic = open('picture.png', 'rb').read()
+        curs.execute("insert into blobs (file) values (%s)",
+            (psycopg2.Binary(mypic),))
