11.0.0

Breaking changes

  • Require Node.js ^22.22.3, ^24.15, or >=26.0.

  • Publish an ESM package with an explicit exports entry point. CommonJS require('postcss-calc') remains
    supported on the supported Node.js versions.

  • Remove the preserve option. Transformations now always update declarations, enabled media-query
    parameters, and enabled selectors in place.

Features

  • Rewrite the calculation engine around a CSS-aware tokenizer, Pratt parser, canonical AST, simplifier,
    and serializer.

  • Add simplification support for modern CSS math functions, including abs(), sign(), mod(), rem(),
    round(), trigonometric functions, pow(), sqrt(), hypot(), log(), and exp().

  • Improve public TypeScript declarations, including the exported PostCssCalcOptions type.

Bug fixes

  • Preserve correct grouping when simplifying subtractions involving custom properties and other opaque
    expressions.

  • Improve numerical precision and rounding, including signed-zero and exact-multiple mod()/rem()
    behavior.

  • Fix handling of identifier-like negative tokens and selector calculations.

  • Maintain left-to-right evaluation order when folding product terms.
