xxHash new release v0.7 : the family is expanding with a new member, XXH3, offering dramatically improved speed for both large and small inputs : https://fastcompression.blogspot.com/2019/03/presenting-xxh3.html …
I just cleaned up an RC this week and @NoHatCoder needs some time to look it over and ensure I didn't break anything crypto-sensitive :) SMHasher is still not a very good test suite and, at least as far as I can tell, the only way to know if a hash is good is to manually inspect.

Crypto ain't my area of expertise, but it seems to me that most functions of non-trivial complexity are just very hard to "randomly" find collisions for. You have to look at the algorithm and see how collisions are likely to occur, and SMHasher doesn't do that (obviously).

So it ends up being more like a virus checker. It has a bunch of tests designed to find problems that _other_ hashes have had, but if it doesn't have a test designed to find problems _your_ hash has, well... you get the idea.
