To finalize JuliaLang/julia#26307, we need to backport the recent changes from #1136, since many packages still haven't bumped their compat entries to v1 and higher, see JuliaLang/julia#26307 (comment). So, I have a branch that does the backport, but I need a place to make a PR, from where a version v0.12.6 could be released. Could someone please help me with that?
