Update: Looks like the app got another small bug fix update for the second time today, bumping up the version number to 188.8.131.52.
Original story Facebook Messenger for Windows Phone got a new update today, but don't get too excited as it just bumps up the version number to 184.108.40.206 with what appear to be just bug fixes.
In other words, this update isn't nearly as significant as the last one that was released last week, which added a way to forward messages and photos. Still, feel free to grab the new version and see if it works any better for you. Thanks to the many folks who tipped us!
