The importance of updating
Keeping Skype up to date is the only way you can take advantage of these improvements, and is vital to making sure that Skype remains safe and secure.
As a result, we use a variety of methods to help make sure you’re aware of the latest versions when they appear. You can subscribe to our blogs, follow us on Twitter or head to our Facebook Page. We also display reminders inside Skype, in the App Store on iOS, and in the Android Market to let you know that there’s an update ready. On Windows, we now make it easy to stay up to date by downloading new versions in the background while you work.
An important note: From time to time, we may discontinue older versions of Skype – this helps us keep things safe and secure, helps us tune our customer support efforts to focus on the latest versions, and, most importantly, makes sure you’re benefiting from all the latest goodies, including features like group video calling which require everyone to be using the latest version of Skype. In these situations, you’ll have to update in order to continue to use Skype, plain and simple.
