So I did an update to my packages, and something else I have installed caused `Plots.jl` to go way back to version `v0.28.4`. I was wondering if there’s a way I can figure out what other packages I have installed that’s causing that.

This just happened to someone else in slack too. The easiest way to check is to do `] add Plots@1.<whatever>` and see what the resolver tells you is holding you back

Just guessing, probably DataStructures v0.18 or JuMP for blocking it, or the other 20 packages blocking it which then is causing version resolution problems.
