This is in the the bloat category:

Added a built-in Emoji set for operating systems without native Emoji fonts (Windows 8.0 and lower and Linux)

Do you prefer that web pages using Emoji not render as expected for people on Linux and Windows XP/Vista/7/8?

Do you think that's a useless feature though? Seeing squares all over the internet isn't exactly a good experience, finding the right font sets to fix your emoji problem can be tricky on Linux too

EDIT: just got the update and it a) fixed some emojis I somehow didn't have, namely "thinking face", which is of course critically important and b) made the rest look a lot livelier.

I'll take squares over emojis any day.
