I noticed:
JuliaPackaging/Yggdrasil#5650

I didn't look into how you download Python, but if you use that, I suggest upgrading to that version (when that PR is merged).

Conversely for Python users, you download Julia, and wants to download latest Julia, how do you do that? Could it or should it use juliaup?
