+
+* It helps with configuration of multiple appenders and layouts.
+* Has a facility to catch context fields and to log them.
+* Has a macro to log unhandled errors.
+* Adds a layout to write messages as JSON, which is useful for production as
+makes easier to parse and process such logs.
+* Uses the appenders which are not disabled in case of some error which again,
+should be useful for production.")
