 - Update to version 0.4.0:
-  * This release is a complete rewrite of the old wf-config
+  * The syntax of the config file itself has not changed, but the
+    new `wf-config` tool can check option types when reading from
+    the config file, and for integers and doubles in can also
+    check whether the config value is between a specified minimum
+    and maximum value. This information is used for displaying
+    proper error messages when the option value is invalid. There
+    is also support for setting custom default option values via
+    a system configuration file.
