+v2.4.1 2015-09-02
+=================
+
+Note: #2554 fixes a regression where ``group_list`` and ``organization_list``
+      where returning extra additional fields by default, causing performance
+      issues. This is now fixed, so the output for these actions no longer returns
+      ``users``, ``extras``, etc.
+      Also, on the homepage template the ``c.groups`` and ``c.group_package_stuff``
+      context variables are no longer available.
+
+
+Bug fixes:
+
+* Fix dataset count in templates and show datasets on featured org/group (#2557)
+* Fix autodetect for TSV resources (#2553)
+* Improve character escaping in DataStore parameters
+* Fix "paster db init" when celery is configured with a non-database backend
+* Fix severe performance issues with groups and orgs listings (#2554)
