With the Watch, you’ll now be able to receive Likes, stickers, and voice clips right on your wrist. And with the iPad, thanks to split-screen multitasking, you can now use Messenger while you’re using another app as well.
Here are Facebook’s release notes:
You can now use Messenger on watchOS 2! Send and receive voice clips, Likes, stickers and more. With iOS 9, you can now find Messenger contacts and conversations from your phone’s search screen, and access Messenger from the list of multi-tasking apps on your iPad.
Enjoy…
