+=============
+Version 4.9.2
+=============
+
+Version 4.9.2 of mod_wsgi can be obtained from:
+
+  https://codeload.github.com/GrahamDumpleton/mod_wsgi/tar.gz/4.9.2
+
+Bugs Fixed
+----------
+
+* When using ``mod_wsgi-express`` in daemon mode, and source code reloading
+  was enabled, an invalid URL path which contained a byte sequence which
+  could not be decoded as UTF-8 was causing a process crash.
