pkgconf 1.9.0 is released 🎉

Please note that this version has an entirely new solver which flattens dependency graphs and explicitly breaks cycles.

It will have different behavior in edge cases from older releases of pkgconf and wildly different behavior from freedesktop pkg-config.

I recommend that distributions push this to their unstable branches, but not to release branches, given its experimental nature.
