Facebook Messenger is poised to give WhatsApp a run for best messenger service, even if they're both technically owned by the same company. Although WhatsApp had an update tonight (two, if you really want to count), Facebook Messenger has also been bumped to version to 5.0.1. If you know build numbers for software that 0.0.1 update should tell you this is a minor bug fix, with no new features.
Facebook Messenger hit 5.0 last Thursday, gaining Groups support and more in a fairly significant update. Much like WhatsApp though, after a major release comes the cleanup, patching little quirks and improving performance.
If you use Facebook Messenger, head to the Store now to grab 5.0.1, and maybe it'll address some issues you've been experiencing.
Thanks, everyone, for the tips!
