The 6.x line is now in security-only maintenance

This release exists because the advisory above covers every published 6.x version, and until now the only remediation on offer was an upgrade to 7.x. 6.1.5 is the patched version for the 6.x line.

The line is kept alive for the installed base that cannot move to 7 yet, Tailwind CSS 3 in particular, which depends on ^6.1.2. From here on it receives security fixes only: no features, no other bug fixes, no type changes. Everything else goes to 7.x, where this package is actively developed. Tailwind CSS 4 no longer depends on this package at all, so this line is expected to retire on its own.

6.1.5 is published under the legacy-v6 npm dist-tag, so npm install postcss-selector-parser keeps resolving to 7.x. Existing ^6
