Major Changes

• Add "auto" to the api option and make it the default. When the Sass implementation supports the modern compiler, "auto" enables it and reuses a single long-running compiler across files, which significantly improves build performance; otherwise it falls back to the modern API. (by @​alexander-akait in #​1319)

• Remove node-sass support. (by @​alexander-akait in #​1316)

• Minimum supported NodeJS version is 22.11.0. (by @​alexander-akait in #​1318)

• Convert source to native ECMAScript modules. The package now declares "type": "module" and exposes both an ESM and a CommonJS build via the exports field. CommonJS consumers continue to work via require, and ESM consumers can now import the loader directly. (by @​alexander-akait in #​1322)

• Remove legacy Sass JS API support. (by @​alexander-akait in #​1316)

Minor Changes

• Added types. (by @​alexander-akait in #​1312)

⚠ BREAKING CHANGES

• use modern Sass JS API by default for sass and sass-embedded

[!WARNING]

The sass options are different for the legacy (before) and modern APIs. Please look at docs how to migrate to the modern options.
Legacy options - https://sass-lang.com/documentation/js-api/interfaces/legacystringoptions/
Modern options - https://sass-lang.com/documentation/js-api/interfaces/options/

To return to the previous logic use:

module.exports = {
  module: {
    rules: [
      {
        test: /\.s[ac]ss$/i,
        use: [
          "style-loader",
          "css-loader",
          {
            loader: "sass-loader",
            options: {
              api: "legacy",
              // Your options
            },
          },
        ],
      },
    ],
  },
};
