iOS 11.1 was released on October 31, 2017 and includes 240 new emojis including Giraffe, Face Vomiting, Genie, Sauropod (dinosaur) and more. A number of existing emojis changed in this update, such as Honeybee, Ram, and Tumbler Glass.
I use four emojis. This is overkill for me.
UPDATE: There seems to be some discrepancy in the number of emojis announced but, as Kip Beatty pointed out in the comments below:
The number is so high because for many of the emojis Apple now adds a range of skin tones to cover a variety of ethnicities.”
Makes sense. Thanks Kip!
