This is not JuliaHub. I have no idea why this exists—maybe the point is to generate traffic and/or SEO for the SQL analytics platform linked on the front page, which doesn’t appear to have anything to do with Julia—but it certainly isn’t a place to look for valid, up-to-date Julia documentation. As @Benny points out, the list of functions matches pre-1.0 Julia, including names like A_mul_B!.
Stick to the official documentation at https://docs.julialang.org.
