Metropolia tempered the terms of service of the cloud services. A new policy allows you to submit exercises and other material through cloud services but you may not upload personally identifiable grading information onto them. More on the terms of service.
Data security of Google Apps for Education was improved. You may now deploy an optional two-factor authentication. More on the web site of Google.
