"Today, we are rolling out an updated version of Skype (version 8.0) for desktop that will replace Skype version 7.0 (also known as Skype classic). We are encouraging everyone to upgrade now to avoid any inconvenience as only Skype version 8.0 will work after September 1, 2018. As we roll out improvements, there comes a time when we must shut down older services and application versions." https://blogs.skype.com/news/2018/07/16/upgrade-to-the-latest-version-of-sky...
