There were some variance regarding the way the MaxScale log (i.e. the file log) was called; "maxlog" in configuration file and "maxscalelog" at the command line and maxadmin interface. Now it is uniformly referred to as "maxlog" in the configuration file, at the command line, from maxadmin and in the code.
