with moodle 3.5, in the log, the user is always identified by his ID :
exemple : The user with id '225' updated the profile for the user with id '259'.
Is there a little setting to only add the username with the ID ?
Moreover, is there another log to know which field of the profile have been updated by a user ? maybe another log level or system log plugin ?
Mayebe there is a plugins to "backup" the profil before any update and compare them after the update ?
