Apple has just seeded the third beta of macOS Sierra 10.12.2 to developers, one week after releasing the second 10.12.2 beta and three weeks following the public release of macOS 10.12.1.
The new emoji include support for many Unicode 9 characters like clown face, selfie, face palm, and more. Additionally, the artwork of many existing emoji have also been updated to make them look more real life.
While not mentioned in the official changelog, the latest Sierra beta should also help fix minor bugs and issues reported by owners of the new 13-inch MacBook Pro without TouchBar.
The third macOS Sierra 10.12.2 beta is available for download through the Apple Developer Center and through the software update mechanism in the Mac App Store.
