+  - When the daemon should switch to another user ID (ServerID is defined in
+    the configuration file) and is not running in a chroot environment, it
+    changes it's working directory to the home directory of this user. This
+    should enable the system to write proper core files when not running with
+    root privileges ...
   - Enhanced the "test suite": please have a look at src/testsuite/README!
