      Is there a written summary of the parts that are new somewhere?

          We've been busy implementing crypto with it, but you can check our talk or the list of closed PRs. Off the top of my head, stuff we added:

          You should check it out, ed25519-dalek might be useful, since it seems faster than the implementation in Ring.

          There are quite a few paths forward to make *ring*'s EdDSA and X25519 faster. It will be a little while before we see which one we pick.

          I did notice that you left *ring*'s EdDSA verification off the graph. Why? Also, what about the X25519 performance comparison?

          Just because it wasn't in the crypto-bench crate — the only reason we included it was to give perspective on the donna/dalek numbers.
