WhatsApp has published a new support document that shares details on ending support for devices running iOS 9 and earlier versions of the operating system (OS). To date, iOS 9 users were able to use the encrypted chat service. However, now iOS 10 is required which means users will need an iPhone 5 or later model to use WhatsApp. The change will affect users of the iPhone 4S for the most part.
