New in Messaging (if enabled):
- You can send files to one another
- You can mention someone using an @ symbol to notify them directly.
- Channel managers can restrict channel invites to managers
- Managers can also set artwork and descriptions for a group channel
- Administers can set channels to be public for anyone to join

Fixed:
- Media playback now stops when you force close the app
- Fixed a Messaging issue causing link previews to cause the channel to crash
