   eta tasks are sorted by time, so we don't have to poll the whole list all the
   time.
 
+* Does not longer use the python-daemon pidfile implementation, but a custom
+  one that doesn't create those weird ``.lock`` and thread files.
+
+* The ``--uid`` and ``--gid`` arguments now support supplying the uid and gid
+  as a username or group name.
+
+* Now ignores permission denied errors when removing the pidfile so it's
+  possible to shutdown when running as an unprivileged user.
+
+* ImportErrors are now properly propogated when autodiscovering tasks.
+
+* You can now use ``celery.messaging.establish_connection`` to establish a
+  connection to the broker.
+
+* When running as a separate service the periodic task scheduler does some
+  smart moves to not poll too regularly, if you need faster poll times you
+  can lower the value of ``CELERYBEAT_MAX_LOOP_INTERVAL``.
+
+* You can now change periodic task intervals at runtime, by making
+  ``run_every`` a property, or subclassing ``PeriodicTask.is_due``.
+
+* The worker now supports control commands enabled through the use of a
+  broadcast queue, you can remotely revoke tasks or set the rate limit for
+  a task type.
+
+* The services now sets informative process names (as shown in ``ps``
+  listings) if the :mod:`setproctitle` module is installed.
