The officially supported list is (and has been since FreeBSD 5 was = current): HEAD builds on =93recent=94 -current systems, tip of the latest stable = branch, latest stable branch latest release. That=92s the entire supported list. What often works is: HEAD builds on any system back to the branch point = of the most recent stable branch and any point on the stable branch. = Frequently back one or two stable branches. We have people actively = ensuring that most points on the latest stable branch (10) work, and at = least one person who submits fixes for 9 and I don=92t think we=92ve = broken 8 (there may be a person for that too, I haven=92t seen any = commits). Currently, we can build on 8.4 (last time I checked), but that may = change with the next clang import since 8.4 doesn=92t have a compiler = that can build it. We administratively block 7.x support and have = removed it from our build system. Really old branches are impossible to = test, so we balance GCing support for them with their usefulness. Warner=
