The most popular instant messaging app, Whatsapp, has just released a new update for the Android version of its app that sports a refreshing new material design update. The app can either be sideloaded from Whatsapp's official site though you may have to wait for the official version just yet. The layout looks scaringly familiar to Google's Hangouts app with a bit of more added colors. The dark green color scheme is a welcome change. Here are the screenshots: The new circular contact photos are reminiscent of the iOS version of the app. Sadly, there is no word as to when the new update will arrive on iOS.
