Wow, thanks a lot. I'm kind of surprised I didn't knew this because I recall searching quite a bit for such a tool/script. In my defense it was around when 1.6 got released ... if anything this shows how fast the julia community grows(or how slow I keep up).

It's fairly new. It was announced at JuliaCon last month (early this month? I forget) that it will soon be the default recommended way to install Julia moving forward. I'm personally hugely excited about it (Julia's been my main squeeze since v0.3-alpha). They just need to work on non-interactive installs so it's easy to incorporate juliaup in a docker container (this may actually be fixed, haven't checked in a couple weeks).
