+Version 4.5.4
+=============
+
+Version 4.5.4 of mod_wsgi can be obtained from:
+
+  https://codeload.github.com/GrahamDumpleton/mod_wsgi/tar.gz/4.5.4
+
+Bugs Fixed
+----------
+
+1. When using Apache 2.4 and daemon mode, the connection and request log
+   IDs from the Apache child worker processes were not being copied across
+   to the daemon process so that log messages generated against the request
+   would use the same ID in logs when using the ``%L`` format modifier.
+
+2. When using Apache 2.4 and daemon mode, the remote client port
+   information was not being cached such that log messages generated
+   against the request would use the port in logs when using the ``%a``
+   format modifier.
+
+Features Changed
+----------------
+
+1. If ``sys.stdout`` and ``sys.stderr`` are used in the context of the
+   thread handling a request, calls against them to log messages will be
+   routed back via ``wsgi.errors`` from the per request WSGI ``environ``
+   dictionary. This avoids the danger of logged messages from different
+   request handlers being intermixed as buffering will now be done on a per
+   request basis. Such messages will also be logged with the correct
+   connection and request log ID if the ``%L`` formatter is used in the
+   error log format.
+
+New Features
+------------
+
+1. Added new option ``--error-log-format`` to ``mod_wsgi-express`` to allow
+   the error log message format to be specified.
+
+2. Pass through to the WSGI per request ``environ`` dictionary new values
+   for ``mod_wsgi.connection_id`` and ``mod_wsgi.request_id``. These are
+   the Apache log IDs for the connection and request that it uses in log
+   messages when using the ``%L`` format modifier. This only applies to
+   Apache 2.4 and later.
