Breaking changes

This release drops official support for unmaintained long term support Node.js releases 14 and 16. It also drops support for non-long term support releases 19 and 21 and add support for Node.js 22. Only the package.json engines field has been updated. The code should otherwise be identical to the previous 6.1.2 release.

Major Changes

• 99d1e6a: postcss-normalize-url: remove normalize-url configuration options

• ca9d3f5: Switch minimum supported Node version to 14 for all packages
• 39a2040: feat!(cssnano): remove undocumented YAML config support

Migration instructions

• If you're not happy with the defaults for the normalize-url transform, turn it off completely. Options were removed as most would change the meaning of the URL, which is unexpcted in the case of CSS minification.
• In the unlikely event you're using YAML to configure cssnano, move the cssnano configuration inside the PostCSS config or use a configuration file in CommonJS or JSON format.
