I was going to look up pipe. In 0.3 it can't be found (I guess |> can). I used to be able to go to 0.4 (a thingy in the down-left corner, that is now missing).
I'm not saying pipe, etc. should be in 0.3 docs (or maybe 0.4 things clearly marked?), but shouldn't Compat.jl be there: http://docs.julialang.org/en/release-0.3/search/?q=compat&check_keywords=yes&area=default -- Palli.
