Well, not really. While the official releases are quite conservative you can follow CURRENT, which is (as the name suggests) the current development tree. It is all out in the open and if you want something which has not been officially released you can get yourself a copy of the source tree, build yourself a new world ("make world") and you have a current FreeBSD (I cannot speak for the other BSD variants here, but I think the process is similar) with all warts and all the new shiny developments. Oh - and all the bugs.
