Facebook Messenger was updated to v126.96.36.199 in Windows Phone Store today. There was no change log mentioned in the listing, so it must be a bug-fix release with no new features. Earlier this month, the app was updated with the ability to forward a message or photo to someone who isn’t in the conversation. Also, Facebook made big improvements to the app’s overall performance. Also, you can now choose between two options on how to use the enter button while messaging.
