Changes

JavaScript API

• Dart Sass's JS API now supports running in the browser. Further details and instructions for use are in the README.

Embedded Sass

• The Dart Sass embedded compiler is now included as part of the primary Dart Sass distribution, rather than a separate executable. To use the embedded compiler, just run sass --embedded from any Sass executable (other than the pure JS executable).

  The Node.js embedded host will still be distributed as the sass-embedded package on npm. The only change is that it will now provide direct access to a sass executable with the same CLI as the sass package.

• The Dart Sass embedded compiler now uses version 2.0.0 of the Sass embedded protocol. See the spec for a full description of the protocol, and the changelog for a summary of changes since version 1.2.0.

• The Dart Sass embedded compiler now runs multiple simultaneous compilations in parallel, rather than serially.

See the full changelog for changes in earlier releases.

Dart Sass 1.62.1

To install Sass 1.62.1, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Fix a bug where :has(+ &) and related constructs would drop the leading combinator.

See the full changelog for changes in earlier releases.

Dart Sass 1.62.0

To install Sass 1.62.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Deprecate the use of multiple !global or !default flags on the same variable. This deprecation is named duplicate-var-flags.

• Allow special numbers like var() or calc() in the global functions: grayscale(), invert(), saturate(), and opacity(). These are also native CSS filter functions. This is in addition to number values which were already allowed.

• Fix a cosmetic bug where an outer rule could be duplicated after nesting was resolved, instead of re-using a shared rule.

See the full changelog for changes in earlier releases.

Dart Sass 1.61.0

To install Sass 1.61.0, 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: Drop support for End-of-Life Node.js 12.

• Fix remaining cases for the performance regression introduced in 1.59.0.

Embedded Sass

• The JS embedded host now loads files from the working directory when using the legacy API.

See the full changelog for changes in earlier releases.

Dart Sass 1.60.0

To install Sass 1.60.0, 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 the pi, e, infinity, -infinity, and NaN constants in calculations. These will be interpreted as the corresponding numbers.

• Add support for unknown constants in calculations. These will be interpreted as unquoted strings.

• Serialize numbers with value infinity, -infinity, and NaN to calc() expressions rather than CSS-invalid identifiers. Numbers with complex units still can't be serialized.

See the full changelog for changes in earlier releases.

Dart Sass 1.59.3

To install Sass 1.59.3, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• Fix a performance regression introduced in 1.59.0.

• The NPM release of 1.59.0 dropped support for Node 12 without actually indicating so in its pubspec. This release temporarily adds back support so that the latest Sass version that declares it supports Node 12 actually does so. However, Node 12 is now end-of-life, so we will drop support for it properly in an upcoming release.

See the full changelog for changes in earlier releases.

Changes

Command Line Interface

• Added a new --fatal-deprecation flag that lets you treat a deprecation warning as an error. You can pass an individual deprecation ID (e.g. slash-div) or you can pass a Dart Sass version to treat all deprecations initially emitted in that version or earlier as errors.

• New --future-deprecation flag that lets you opt into warning for use of certain features that will be deprecated in the future. At the moment, the only option is --future-deprecation=import, which will emit warnings for Sass @import rules, which are not yet deprecated, but will be in the future.

Dart API

• New Deprecation enum, which contains the different current and future deprecations used by the new CLI flags.

• The compile methods now take in fatalDeprecations and futureDeprecations parameters, which work similarly to the CLI flags.
