It is highly possible that ServiceNow can update roles, child roles, ACLs, introduce new roles, remove existing roles.

Reason for each will be different.

You can go through the Yokohama Release notes to know all the updates.

Accept the solution and mark as helpful if it does, to benefit future readers.
