The most important feature of this update is the voice dictation to respond to messages. Facebook has thought of everything, if you do not want to answer with your voice and want to show that you agree, you can send the famous thumbs-up to friends. So you can chat with your friends from your watch.
This update is a bit light because it provides fewer features and updates may arrive later to add others.
You can download the update by going here the Play Store.
