There's a whole host of improvements coming to Facebook Messenger version 5.0: photo sharing has a new, streamlined design, improving accessibility; there are new shortcuts for downloading sticker packs; and the kicker, recording and sharing video. For the moment, the update is only available on iOs, and will come to Android later this week.
Have they improved the part about draining my battery/data plan and pinging me whether I've disabled notifications or not? I deleted Messenger because it annoyed me. If the new version still does and FB strips the function from their main app, I'll see how quickly I can become accustomed to living without Facebook messages.
