Dart Sass 1.66.0

To install Sass 1.66.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Breaking change: Drop support for the additional CSS calculations defined in CSS Values and Units 4. Custom Sass functions whose names overlapped with these new CSS functions were being parsed as CSS calculations instead, causing an unintentional breaking change outside our normal [compatibility policy] for CSS compatibility changes.

  Support will be added again in a future version, but only after Sass has emitted a deprecation warning for all functions that will break for at least three months prior to the breakage.

See the full changelog for changes in earlier releases.

Dart Sass 1.65.0

To install Sass 1.65.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• All functions defined in CSS Values and Units 4 are now parsed as calculation objects: round(), mod(), rem(), sin(), cos(), tan(), asin(), acos(), atan(), atan2(), pow(), sqrt(), hypot(), log(), exp(), abs(), and sign().

• Deprecate explicitly passing the % unit to the global abs() function. In future releases, this will emit a CSS abs() function to be resolved by the browser. This deprecation is named abs-percent.

Changes

• Comments that appear before or between @use and @forward rules are now emitted in source order as much as possible, instead of always being emitted after the CSS of all module dependencies.

JavaScript API

• Add a new SassCalculation type that represents the calculation objects added in Dart Sass 1.40.0.

• Add Value.assertCalculation(), which returns the value if it's a SassCalculation and throws an error otherwise.

• Produce a better error message when an environment that supports some Node.js APIs loads the browser entrypoint but attempts to access the filesystem.

Embedded Sass

• Fix a bug where nested relative @imports failed to load when using the deprecated functions render or renderSync and those relative imports were loaded multiple times across different files.

Changes

JavaScript API

• Re-enable support for import sass from 'sass' when loading the package from an ESM module in Node.js. However, this syntax is now deprecated; ESM users should use import * as sass from 'sass' instead.

  On the browser and other ESM-only platforms, only import * as sass from 'sass' is supported.

• Properly export the legacy API values TRUE, FALSE, NULL, and types from the ECMAScript module API.

Embedded Sass

• Fix a race condition where closing standard input while requests are in-flight could sometimes cause the process to hang rather than shutting down gracefully.

• Properly include the root stylesheet's URL in the set of loaded URLs when it fails to parse.
