Could you also please put the compat entry of "julia" in Project.toml down as in https://github.com/mikeingold/MeshIntegrals.jl/pull/46/files? Then CompatHelper doesn't want to do that the next time

[mikeingold]

Oops, missed that change. Is there a reason why it prefers to have the "julia" entry on the final line? Looks otherwise unchanged.

[JoshuaLampert]

I think it's a convention to have it as the final line (?)
