As discussed in Towards Practical Attacks on Argon2i and Balloon Hashing by Joel Alwen and Jeremiah Blocki, there have been significant changes to the version of Argon2 which won the Password Hashing Competition in 2015. The lastest version is 1.3, as described in the March 24, 2017 version of the Argon2 paper Argon2: the memory-hard function for password hashing and other applications by Alex Biryukov, Daniel Dinu, and Dmitry Khovratovich.
The current (2020) version of
argon2-cffiimplements version 1.3, as evidenced by the$v=19(0x13) parameter in the produced hashes, but that is not documented anywhere in the repo that I've seen.The README and the documentation should indicate which version is implemented, and document when it changes in the Changelog.
