The new emojis follow Apple's bulk addition of new emoji characters to iOS last year, but Facebook claims that Messenger is the first platform to feature a female police officer, runner, pedestrian, surfer, and swimmer, and notes that more are to come in the near future.
Facebook also notes that it is making changes to how emojis are displayed in the app.
Previously, some users would see replacement emoji characters that were native to their device, but now all users will see the same ones, irrespective of how they access the service. The company says that this will ensure that no one will see "broken-looking black boxes or emojis that just don't make sense."
Additionally, Facebook announced the addition of a new emoji picker for all platforms, located in the iOS app at the left of the composer.
Facebook Messenger is a free download for iPhone and iPad on the App Store. [Direct link]
