the PR ( https://github.com/php/php-src/pull/13194 ) got the first merge
conflict. I fixed it, but what's next?
Could vote on it, if there is little more to discuss?
quick recap
AMD Ryzen 9 7950x:

just tested ARM Neon optimizations on Oracle Cloud's cheapest ARM VPS:

Depends on the actual numbers: is there any way to make a comparison that
is relatively stable across architectures?
Would it be feasible to

Maybe vote on it? (that was suggested in the PR too,
https://github.com/php/php-src/pull/13194#issuecomment-1900430400 )
Can think of 6 things
1: Should BLAKE3 be added to PHP? yes/no
2: Should ARM Neon (2007) optimized implementation be bundled? yes/no
3: Should x86_64 SSE2 (2000) optimized

we can look into exposing blake3's XOF (arbitrary length) capabilities
after (and if) initial

Just an etiquette note, please don't top post on the mailing list. [1]
I have no idea what this sentence is replying to, and it makes following the
That's why I suggested implementing separate length algorithms like we have
for SHA3.

Having looked into it, it seems difficult after all,
I would want a new $options argument for hash_final(), and some
internal changes to struct php_hash_blake3_ops,
and that internal change would have to be updated for all other hashes
PHP support..
I'm not up for doing that now.
And I think it
>BLAKE3 has 2 default sizes
Nope, only 1 canonical size, 256 bits.
*BUT* BLAKE3 is XOF, it can be exactly as long as you want it to be:
$ echo test | b3sum --length 5
dea2b412aa -
$ echo test | b3sum --length 10
dea2b412aa90f1b43a06 -
$ echo test | b3sum --length 32

Can we add the BLAKE3 hash?
Created a PR here: https://github.com/php/php-src/pull/13194
BLAKE3 is a very fast ("blazing fast") cryptographically secure hash. It is
the latest iteration of the BLAKE hash, which was a SHA3 finalist~ see
https://github.com/BLAKE3-team/BLAKE3 for more info on
