What happened to 16?

I just got a new laptop and tried to boot 13.5,14 and 15
but it hangs at the video -- something about loosing contact
with sc. So I went to get a copy of 16. But download.freebsd.org
doesn't know where it is. All the links to it from FreeBSD.org
return 404.

So where is it?

Thanks! :-)
