WhatsApp Beta snagged a new update for Windows Phone devices. WhatsApp hasn’t introduced any new features but there are noticeable changes in terms of UI. The updated version of WhatsApp Beta is 2.16.310
Windows 10 Mobile users can now hide the (annoying) navigation bar in WhatsApp Beta. A small bar between chat window and navigation bar has been removed as well. You will also notice performance improvements with the latest update.
