Since IntervalArithmetics.jl currently requires Julia 1.5, I guess it makes sense to require the same here at least; this would solve the broken tests (due to the introduction of numtype).

Should we require IntervalArithmetic v0.20 and later? And then bump a new minor version.

Should we require IntervalArithmetic v0.20 and later?

Either that or you need to make the change eltype → numtype version dependent. (I guess it would fail with older versions of IA, which you do not see in the build here because it only uses the latest version.)

[lucaferranti]

huups, apologies for not noticing you tagged me. Anyway, I agree with Christian that it may make sense to update the compatibilities with IA and Julia. The documentation check seems to fail, but it seems to be unrelated to this PR

[lbenet]

@lucaferranti Thanks for the comment; do you understand the problem with the docs? Locally, I can't reproduce it.

[schillic]

Have you tried retriggering? It could just be a random failure.

[lucaferranti]

it was a plotting related issue, when Plots.jl is used with the GR backend, then it requires the small trick of my latest commit, more details here.

I am not sure why this didn't come up before, probably because this PR added Plots.jl as deps in the docs Project.toml

[lbenet]

Thanks @lucaferranti for fixing this! So I'll merge and then tag the new version!
