iOS 11.0 was released to the public today, and it does not contain any emoji updates.
Update: iOS 11.1 has new emojis and comes out late October or early November 2017.
But that day is not today.
Above: A sample of new emojis previewed by Apple for late 2017 release.
At the time of writing. Stay tuned. My tip: new emojis (and possibly some design changes) will come in whichever iOS version comes preinstalled on the iPhone X. ↩︎
