  * A spandsp based fax backend (res_fax_spandsp) has been added.
  * The app_fax module has been deprecated in favor of the res_fax module and
    the new res_fax_spandsp backend.
- * A new FAX logger level has been created for spandsp replacing the DEBUG logger
-   level. The logger.conf.sample file has been update to include an example. 
+ * The SendFAX and ReceiveFAX applications now send their log messages to a
+   'fax' logger level, instead of to the generic logger levels. To see these
+   messages, the system's logger.conf file will need to direct the 'fax' logger
+   level to one or more destinations; the logger.conf.sample file includes an
+   example of how to do this. Note that if the 'fax' logger level is *not*
+   directed to at least one destination, log messages generated by these
+   applications will be lost, and that if the 'fax' logger level is directed to
+   the console, the 'core set verbose' and 'core set debug' CLI commands will
+   have no effect on whether the messages appear on the console or not.
