By default, when picking the version to show on badge, all rolling, noscheme, incorrect, untrusted, ignored versions are skipped (so, for instance, rolling 9999 versions in Gentoo do not hide real stable versions). When allow_ignored parameter is specified (with some non-empty value), the greatest version is always picked regardless of status. great lakes mechanical corp
