I think Emojipedia is a terrific resource. If you’ve not spent time here before, jump to the linked page, showing the emoji changes that came with this iOS release. First, there’s there’s the high resolution images of the 17 emoji that have changed.
I love the attention to detail here. The old one looks like a bit flat, and the scotch (or whatever is in it) looks cloudy. The new one looks more realistic.
[UPDATE: Apparently, the tumbler emoji was updated, then reverted back to the old version, then updated back to the new one, perhaps as a result of a QA oversight. Regardless, nice to see the design improvement.]
Another thing to note about this page is “all, changed, new, removed” links. Each gives you a different, useful view into the current emoji.
And, if you are interested, you can scroll down and tap on the links for previous versions of iOS, to see what was new with those releases. Good stuff.
