It does NOT and, I hope, never will - all these "password history policies" require storing plaintext password somewhere, which is absolutely inacceptable. The only possible check is whether new password is the same as current - it is the only which can be verified using the current password hash (in that case user can switch between two passwords, but it is really safer to remember them than writing every new password down somewhere). -- Alexey V.
