A new version of Messenger is now available for Android users running Ice Cream Sandwich and up. On September 27, Facebook rolled out the latest version, Messenger 42.0.0.16.137 APK, which you can download for free right here at the bottom of this post. Messenger makes it easier to manage your Facebook chats and IMs on your mobile device by optimizing your conversations for smaller screens and allowing the app to operate in the background, with a floating tab that lets you access your chats in one tap. This latest version contains some cool additions and performance enhancements, so it’s a good idea to update to Messenger 42.0.0.16.137 as soon as possible.
