Facebook has released an update to their iOS app that brings with it emotions for status updates and better controls over sharing. Emotions for status updates were released not too long ago on the desktop side of things, but it has now been brought to iOS through this latest update.
Facebook has also made it easier to adjust who can see something you've shared, making it easier to protect your privacy. Of course, Facebook has included the prerequisite "bug fixes," but they have also added in the ability to start a new conversation with photos you receive in messages.
The latest version of the app can be grabbed from the Apple App Store.
