Changelog

1.104.0Latest

Dart Sass 1.104.0

Changed 2
  • Colors now convert the special values NaN and negative zero, as well as infinity and negative infinity for polar-hue channels, to 0 as per the CSS spec
  • The special value negative zero is now serialized as -0 instead of 0 for greater compatibility when using it in CSS calculations

From Sass

To install Sass 1.104.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Potentially breaking compatibility fix: Colors now convert the special values NaN and negative zero, as well as infinity and negative infinity for polar-hue channels, to 0 as per the CSS spec.

  • The special value negative zero is now serialized as -0 instead of 0 for greater compatibility when using it in CSS calculations.

See the full changelog for changes in earlier releases.

1.103.0

Dart Sass 1.103.0

Changed 1
  • Colors now preserve analogous sets of missing channels during conversions, per the CSS spec, so color.to-space(lch(50% none none), lab) now returns lab(50% none none) instead of lab(50% 0 0)

From Sass

To install Sass 1.103.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Potentially breaking compatibility fix: Colors now preserve "analogous sets" of missing channels during conversions, per the CSS spec. For example, color.to-space(lch(50% none none), lab) now returns lab(50% none none) instead of lab(50% 0 0).

See the full changelog for changes in earlier releases.

1.102.0

Dart Sass 1.102.0

Changed 1
  • Use the 2.4 gamma transfer function for rec2020, as specified by the latest draft of CSS Color 4

From Sass

To install Sass 1.102.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Use the 2.4 gamma transfer function for rec2020, as specified by the latest draft of CSS Color 4.

1.101.4

Dart Sass 1.101.4

Changed 1
  • Avoid emitting rgb() or rgba() functions with non-percent decimal channels by using percentages for channels in legacy colors that contain at least one non-integer channel to preserve backwards-compatibility while retaining full precision for modern browsers
Fixed 1
  • Fix a bug where the values of plain-CSS if() expressions were emitted using their meta.inspect() format rather than their CSS serialization format

From Sass

To install Sass 1.101.4, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Avoid emitting rgb() or rgba() functions with non-percent decimal channels. Older browsers only support integer values or (potentially decimal) percentages for these functions, so in order to preserve backwards-compatibility while retaining full precision for modern browsers, legacy colors that contain at least one non-integer channel will now use percentages for their channels (for example, rgb(0%, 100%, 50%) rather than rgb(0, 255, 127.5)).

  • Fix a bug where the values of plain-CSS if() expressions were emitted using their meta.inspect() format rather than their CSS serialization format.

See the full changelog for changes in earlier releases.

1.101.0

Dart Sass 1.101.0

Fixed 1
  • The Node package importer now properly supports resolving import-only variants of Sass files declared in the exports, sass, and style fields of package.json

From Sass

To install Sass 1.101.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Potentially breaking bug fix: The Node package importer now properly supports resolving import-only variants of Sass files declared in the exports, sass, and style fields of package.json. Previously, these files were ignored even when loaded via @import, so any code relying on loading module-system-only files this way may break.

See the full changelog for changes in earlier releases.

1.100.0

Dart Sass 1.100.0

Deprecated 1
  • Writing two compound selectors adjacent to one another without any whitespace between them, such as [class]a, is now deprecated

From Sass

To install Sass 1.100.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

  • Writing two compound selectors adjacent to one another without any whitespace between them, such as [class]a, is now deprecated. This was always an error in CSS and Sass only supported it by mistake.

    See the Sass website for details.

See the full changelog for changes in earlier releases.

1.99.0

Dart Sass 1.99.0

Added 1
  • Add support for parent selectors (&) at the root of the document, which are emitted as-is in the CSS output
Changed 2
  • User-defined functions named calc or clamp are no longer forbidden and will be used instead of the built-in functions if they exist without a namespace in the current module
  • User-defined functions whose names begin with - and end with -expression, -url, -and, -or, or -not are no longer forbidden
Deprecated 3
  • User-defined functions named EXPRESSION, URL, and ELEMENT, those that begin with - and end with -ELEMENT, and the same names with some lowercase letters are now deprecated due to conflicts with plain CSS functions
  • Calls to functions whose names begin with - and end with -expression and -url are deprecated if their behavior will change in the future
  • Calls to functions whose names begin with - and end with -progid:... are deprecated

From Sass

To install Sass 1.99.0, 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 parent selectors (&) at the root of the document. These are emitted as-is in the CSS output, where they're interpreted as the scoping root.

  • User-defined functions named calc or clamp are no longer forbidden. If such a function exists without a namespace in the current module, it will be used instead of the built-in calc() or clamp() function.

  • User-defined functions whose names begin with - and end with -expression, -url, -and, -or, or -not are no longer forbidden. These were originally intended to match vendor prefixes, but in practice no vendor prefixes for these functions ever existed in real browsers.

  • User-defined functions named EXPRESSION, URL, and ELEMENT, those that begin with - and end with -ELEMENT, as well as the same names with some lowercase letters are now deprecated, These are names conflict with plain CSS functions that have special syntax.

    See the Sass website for details.

  • In a future release, calls to functions whose names begin with - and end with -expression and -url will no longer have special parsing. For now, these calls are deprecated if their behavior will change in the future.

    See the Sass website for details.

  • Calls to functions whose names begin with - and end with -progid:... are deprecated.

    See the Sass website for details.

See the full changelog for changes in earlier releases.

1.98.0

Dart Sass 1.98.0

Added 1
  • Add a const Logger.defaultLogger field that emits to standard error or the browser console and automatically chooses whether to use terminal colors
Changed 1
  • Emit colored warnings and other messages on the console when running in a browser
Fixed 3
  • Gracefully handle dependency loops in --watch mode
  • Fix a crash when manually constructing a SassCalculation for 'calc' with an argument that can't be simplified
  • Properly emit deprecation warnings as text rather than StringBuffer objects when running in a browser
