The all-new design and features can now be used by everyone
The latest update to Facebook Messenger, which was first announced about two weeks ago, is now rolling out to all users. Previously only available to a limited number (presumably to catch bugs), the new version with an all-new design and features will be available for everyone to download.
Along with a new white and light blue design (that frankly looks iOS 7-inspired) and faster performance, along with new chat features like the ability to message someone with just their phone number, the latest update is worth a look. It now stands in pretty high contrast to the stand-alone Facebook app, which can be kind of jarring, but the Messenger experience is now much improved.
