+==============
+Version 4.4.19
+==============
+
+Version 4.4.19 of mod_wsgi can be obtained from:
+
+  https://codeload.github.com/GrahamDumpleton/mod_wsgi/tar.gz/4.4.19
+
+For details on the availability of Windows binaries see:
+
+  https://github.com/GrahamDumpleton/mod_wsgi/tree/master/win32
+
+Bugs Fixed
+----------
+
+1. Daemon mode processes were crashing when attempting to set ``USER``,
+``USERNAME``, ``LOGNAME`` or ``HOME`` when no password entry could be
+found for the current user ID. Now do not attempt to set these if the
+user ID doesn't have a password file entry.
