Dart Sass 1.54.0

To install Sass 1.54.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Deprecate selectors with leading or trailing combinators, or with multiple combinators in a row. If they're included in style rules after nesting is resolved, Sass will now produce a deprecation warning and, in most cases, omit the selector. Leading and trailing combinators can still be freely used for nesting purposes.

  See https://sass-lang.com/d/bogus-combinators for more details.

• Add partial support for new media query syntax from Media Queries Level 4. The only exception are logical operations nested within parentheses, as these were previously interpreted differently as SassScript expressions.

  A parenthesized media condition that begins with not or an opening parenthesis now produces a deprecation warning. In a future release, these will be interpreted as plain CSS instead.

• Deprecate passing non-deg units to color.hwb()'s $hue argument.

• Fix a number of bugs when determining whether selectors with pseudo-elements are superselectors.

• Treat * as a superselector of all selectors.

Dart API

• Add a top-level fakeFromImport() function for testing custom importers that use AsyncImporter.fromImport.

JS API

• Add a charset option that controls whether or not Sass emits a @charset/BOM for non-ASCII stylesheets.

• Fix Sass npm package types for TS 4.7+ Node16 and NodeNext module resolution.

See the full changelog for changes in earlier releases.

Dart Sass 1.52.1

To install Sass 1.52.1, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

Command Line Interface

• Fix a bug where --watch mode would close immediately in TTY mode. This was caused by our change to close --watch when stdin was closed outside of TTY mode, which has been reverted for now while we work on a fix.

See the full changelog for changes in earlier releases.

Dart Sass 1.52.0

To install Sass 1.52.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Add support for arbitrary modifiers at the end of plain CSS imports, in addition to the existing supports() and media queries. Sass now allows any sequence of identifiers of functions after the URL of an import for forwards compatibility with future additions to the CSS spec.

• Fix an issue where source locations tracked through variable references could potentially become incorrect.

• Fix a bug where a loud comment in the source can break the source map when embedding the sources, when using the command-line interface or the legacy JS API.

JS API

• SassNumber.assertUnit() and SassNumber.assertNoUnits() now correctly return the number called on when it passes the assertion.

See the full changelog for changes in earlier releases.

Dart Sass 1.51.0

To install Sass 1.51.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Potentially breaking change: Change the order of maps returned by map.deep-merge() to match those returned by map.merge(). All keys that appeared in the first map will now be listed first in the same order they appeared in that map, followed by any new keys added from the second map.

• Improve the string output of some AST nodes in error messages.

See the full changelog for changes in earlier releases.
