This sounds like the kind of thing "Release notes" were designed for. I was not able to find them on the first page of the FreeBSD website, but if you click the big "Get FreeBSD Now" button, there is a link in the table detailing the releases:
http://www.freebsd.org/releases/8.0R/relnotes.html

Good idea ;)

FreeBSD no longer supports "dangerously dedicated" UFS filesystems (section 2.2.5 of Detailed release notes) but I'm not sure if that is possible with gmirror.
