Thanks to Sponsors

This release was possible thanks to our community.

Source Map Performance

Because PostCSS needs synchronous API, we can’t move from the old `source-map 0.6 to 0.7 (many other open-source projects too).

@​7rulnik forked source-map 0.6 to source-map-js and back-ported performance improvements from 0.7. In 8.3 we switched from source-map to this source-map-js fork.

You map see 4x performance improvements in parsing map from processing step before PostCSS (for instance, Sass).

Document Nodes

Thanks to @​gucong3000, PostCSS already parse CSS from HTML and JS files (CSS-in-JS templates and objects).
