Role Watchdog

module_name
role_watchdog
Description

Logs every time a role is changed. Users get a Role History tab and there's a notification feature. 

Not ready for Drupal 8 yet (15 Sep 2018 - there's a dev branch, but when you install it complains about missing role entity, and drush updb does nothing)
