Facebook is Rolling Out a Faster and Simpler Version of Messenger

An update to Facebook Messenger said to be “faster, smaller, and simpler” is rolling out to users over the coming weeks. Facebook detailed the under-the-hood improvements coming to Messenger, which will allow the app to load twice as fast at a quarter of its original size. Messenger’s core code has been reduced by 84% going from more than 1.7 million lines of code to 360,000. In addition, Messenger’s features have been rebuilt to fit this new, simplified infrastructure. Facebook notes that, as a result of reducing the size of the app, some features in Messenger will be temporarily unavailable when the redesign rolls out.
