ClassLink RosterServer now keeps track of user logins and events. This makes it easy to see who has logged in on a particular day, as well as what they did during their session.
Most everything is captured, from changes in an app's permissions to running manual imports. Logs can be filtered by Category and by Timestamp (day).
The Users Data Preview window now includes a column for email. This makes it easier to compare a user's username with their email in cases where a student or teacher is experiencing login issues. If a user does not have an email address, then the cell under Email will be blank.
