Hello, The RFC for introducing Argon2 as an alternative hashing algorithm for the password_* functions is now re-open. The RFC is available at https://wiki.php.net/rfc/argon2_password_hash .
Voting is open for 2 week, and will close on September 7th. A 50%+1 majority required to pass. If you previously voted you will need to vote again, as the original vote was closed shortly after opening due to an issue with the original RFC language. Thanks! *Charles R. Portwood II*
