> members whose passwords have not been compromised benefit from the enhanced security we just recently put in place, which includes hashing and salting of our current password databases.

If we presume that the 6.5m password dump was the past version, it shows that they just hashed the passwords before. This sentence (if I'm interpreting correctly), indicates that they were plaintext and were recently changed from plaintext to hash(salt+password).

I must be missing something in my interpretation though, because there isn't any evidence that they had the plaintext passwords to begin with.

(My assumption is that he means any user that has recently logged in was transparently moved to the hash(salt+password) scheme they are using now and previously just had hash(password) in place.)
