Pardon my possible unawareness, but was this change discussed anywhere?
I understand the rationale to move away from MD5, but reasons for SHA512
seem moot.  I've personally had been using Blowfish for password hashes
since OpenBSD switched to it, for example, as fast and apparently reliable
hash.  Is there anything wrong with it?  Why SHA512 is clear winner here?
FWIW, ports use SHA256 for now.  Could it be that switch to SHA512 will
impose perfomance problems?
