+	The events that logged EVAL_RESULT now log a different message
+	for each triggering event. As a result, the message was split
+	into eight messages. The messages that were logged at INFO level
+	are now logged at the same level as their DEBUG counterparts:
+	level 50. Fixed an issue that was causing some messages to not
+	appear under the "Kea Messages Manual" section. A new section
+	called "Kea Debug Messages By Log Level" is added to the ARM.
