Facebook just moved one step closer toward its goal of allowing users to swap messages across Messenger, WhatsApp and Instagram. Today, the company announced that it's rolling out a new version of Messenger for iOS that's been rebuilt "from the ground up."
This is the "Lightspeed" redesign the company first teased last year at F8. But, besides, faster launch speeds, most users shouldn't notice much of a difference between the new app and the one they've already been using. That's because "Lightspeed" was more about simplifying Messenger's underlying code (Facebook notes the app went from 1.76 million lines of code to 360,000) than adding features to a notoriously bloated app.
