 * Empty HTTP request arguments are no longer ignored.  This applies to
   ``HTTPRequest.arguments`` and ``RequestHandler.get_argument[s]``
   in WSGI and non-WSGI modes.
+* On Python 3, `tornado.escape.json_encode` no longer accepts byte strings.
+* On Python 3, the ``get_authenticated_user`` methods in `tornado.auth`
+  now return character strings instead of byte strings.
 * `tornado.netutil.TCPServer` has moved to its own module, `tornado.tcpserver`.
 * The Tornado test suite now requires ``unittest2`` when run on Python 2.6.

 * Generators may now yield ``Future`` objects.
+* Callbacks produced by `gen.Callback` and `gen.Task` are now automatically

 * Fixed a memory leak involving generators, `RequestHandler.flush`,
   and clients closing connections while output is being written.
 * Yielding a large list no longer has quadratic performance.
