Within each conversation thread, 3D Touch allows for quick previews of any links or contacts posted within a message.
The company also noted that throughout the app, Peek and Pop will be available to "preview contacts, conversations, photos, videos, stickers, links and locations."
Facebook Messenger previously added 3D Touch support on its app icon with a few Quick Actions that present options to jump into recent chats, start a new message, or generate your personal messenger code to add a friend on the service.
Anyone who wants to check out the new 3D Touch features of Facebook Messenger can download the app for free from the App Store. [Direct Link]
