Does rsync use md4 or md5?

[David Depardoux]

Hello,

"NEWS for rsync 3.0.0"
<http://rsync.samba.org/ftp/rsync/src/rsync-3.0.0-NEWS>
says:

"Protocol 30 now uses MD5 checksums instead of MD4."

But the "rsync man page"
<http://rsync.samba.org/ftp/rsync/rsync.html>
does not mention MD5, but only talks about "MD4 checksum".

I guess the man page is only a bit outdated? Or did I misunderstand something?

Regards,
