+          The library reloading behavior has changed in Kea 1.1. Libraries are
+          reloaded, even if their list hasn't changed. Kea does that, because
+          the parameters specified for the library (or the files those
+          parameters point to) may have changed.

+        Libraries may have additional parameters. Those are not mandatory in the
+        sense that there may be libraries that don't require them. However, for
+        specific library there is often specific requirement for specify certain
+        set of parameters. Please consult the documentation for your library
+        for details. In the example above, the first library has no parameters.
+        The second library has five parameters, specifying mail (string
+        parameter), floor (integer parameter), debug (boolean parameter) and
+        even lists (list of strings) and maps (containing strings). Nested
+        parameters could be used if the library supports it. This topic is
+        explained in detail in the Hooks Developer's Guide in Configuring Hooks
+        Libraries section.
