WhatsApp, the Facebook-owned messaging platform, will leave some mobile operating systems behind by the end of this year. BlackBerry, Android 2.1 (Eclair) and 2.2 (Froyo), and Windows Phone 7.1 are among the mobile platforms that will soon miss the popular messaging app. The announcement started by noting that WhatsApp recently celebrated its seventh birthday. “But anniversary dates are also an opportunity to look back,” according to the blog post. Given that the mobile landscape has shifted from one dominated by BlackBerry and Nokia to one taken over by Android and iOS, the company declared that it’s time to refocus their efforts.

This will be sad news for WhatsApp users in developing markets, where some of these older operating systems are still relevant. At the beginning of the month, WhatsApp announced that it has 1 billion users. In January, WhatsApp founder Jan Koum announced that the app would no longer charge a $1 annual fee, making the messaging app completely free.
