v6.0.0

Major Changes

• 99d1e6ab: postcss-normalize-url: remove normalize-url configuration options

• ca9d3f55: Switch minimum supported Node version to 14 for all packages
• 39a20405: 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.
