WhatsApp beta updated to version 2.17.93, the update might seem puny but brings changes to the UI which will make it easy to call and share attachments.
The attachment button which was early located on the top next to search is now moved to the text box, next to camera. Now you won't have to reach out to the top of the screen to share a document or a contact or some sort of media anymore.
Along with this the Voice and Video call buttons have now also been moved to the top title bar. Now you can choose directly which call you want to make instead of tapping the call icon then choosing which call to initiate.
These were the two UI changes that this latest update has brought. The update is currently available in the beta version of the app (join official beta program), but won't take much time to come to the stable version.
