Other great additions:

- Left and Right parenthesis with middle ring [1]

- A wiggly exclamation mark expressing mirth or laughter [1] (edit: and something I completely missed: the inverted version can express sarcasm)

- Cuneiform numerals, including lots of arranged dots that might be useful in other contexts [2]

- New variations of "measured angle" and "sector" [3]

- A transparent cube and a white cube [4]

Also a couple new combining marks

And for anyone who wants to see what the reference images for the new emojis look like:
