The Administration panel now reports specific actions that manage security permissions for users. Each entry row will consist of the following columns:

Administrator Full Name: full name of admin user who performed the given action
User Full Name: full name of the user that the action affects
Description: text description of what has been changed for the given user

Each row is also expandable, showing additional information about activity:

Administration username and email that performed the action
Username and email of the user that the action affects
Country, Region, and IP: GeoIP information if possible of administrator who performed action
User Agent: additional info on Administrator system.
