+Version 4.2.4
+=============
+
+Version 4.2.4 of mod_wsgi can be obtained from:
+
+  https://github.com/GrahamDumpleton/mod_wsgi/archive/4.2.4.tar.gz
+
+Known Issues
+------------
+
+1. The makefiles for building mod_wsgi on Windows are currently broken and
+need updating. As most new changes relate to mod_wsgi daemon mode, which is
+not supported under Windows, you should keep using the last available
+binary for version 3.X on Windows instead.
+
+Bugs Fixed
+----------
+
+1. Fixed one off error in applying limit to the number of supplementary
+groups allowed for a daemon process group. The result could be that if
+more groups than the operating system allowed were specified to the option
+``supplementary-groups``, then memory corruption or a process crash could
+occur.
+
+2. Improved error handling in setting up the current working directory and
+group access rights for a process when creating a daemon process group. The
+change means that if any error occurs that the daemon process group will be
+restarted rather than allow it to keep running with an incorrect working
+directory or group access rights.
+
+New Features
+------------
+
+1. Added the ``--setup-only`` option to mod_wsgi express so that it is
+possible to create the configuration when using the Django management command
+``runmodwsgi`` without actually starting the server.
