+Version 4.1.2
+=============
+
+Version 4.1.2 of mod_wsgi can be obtained from:
+
+  https://github.com/GrahamDumpleton/mod_wsgi/archive/4.1.2.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. The integration for Django management command was looking for the wrong
+name for the admin script to start mod_wsgi express.
+
+2. The code which connected to the mod_wsgi daemon process was passing an
+incorrect size into the connect() call for the size of the address
+structure. On some Linux systems this would cause an error similar to::
+
+    (22)Invalid argument: mod_wsgi (pid=22944): Unable to connect to \
+        WSGI daemon process 'localhost:8000' on \
+        '/tmp/mod_wsgi-localhost:8000:12145/wsgi.22942.0.1.sock'
+
+This issue was only introduced in 4.1.0 and does not affect older versions.
+
+3. The deadlock detection thread could try and acquire the Python GIL
+after the Python interpreter had been destroyed on Python shutdown
+resulting in the process crashing. This issue cannot be completely
+eliminated, but the deadlock thread will now at least check whether the
+flag indicating process shutdown is happening has been set before trying to
+acquire the Python GIL.
