We have a compat entry for Tar.jl Tar = "1.10". CompatHelper always suggests the change Tar = "1.10, 1". I think this is because the latest version of Tar in the General registry is 1.9.2. Tar 1.10 is supplied as a stdlib.
if we look at CompatHelper's understanding:
DepInfo(Package("Tar", UUID("a4e569a6-e804-4fa4-b0f3-eef7a1d5b13e")), v"1.9.2", VersionSpec("1.10.0-1"), "1.10")
It thinks the latest version is 1.9.2. I haven't confirmed but I would guess this is why CompatHelper suggests the version bump to 1.10, 1. So somehow we need to get ComatHelper to understand Tar 1.10 is shipped with Julia? Or maybe Tar 1.10 should be in General?
