There was a problem hiding this comment.
Here the naming is a bit misleading.
That is, with previous implementation the salt was used as the blake2b-rfc "key" argument while the key was used as the "data" argument.
The new_with_salt_and_personal has a dedicated parameter (the 2nd) for the salt. But to obtain the same MAC as before we have to pass salt as the 1st parameter
