To install Sass 1.78.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• The meta.feature-exists function is now deprecated. This deprecation is named feature-exists.

• Fix a crash when using @at-root without any queries or children in the indented syntax.

JS API

• Backport the deprecation options (fatalDeprecations, futureDeprecations, and silenceDeprecations) to the legacy JS API. The legacy JS API is itself deprecated, and you should move off of it if possible, but this will allow users of bundlers and other tools that are still using the legacy API to still control deprecation warnings.

• Fix a bug where accessing SourceSpan.url would crash when a relative URL was passed to the Sass API.

Embedded Sass

• Explicitly expose a sass executable from the sass-embedded npm package. This was intended to be included in 1.63.0, but due to the way platform-specific dependency executables are installed it did not work as intended. Now users can run npx sass for local installs or just sass when sass-embedded is installed globally.

• Add linux-riscv64, linux-musl-riscv64, and android-riscv64 support for the sass-embedded npm package.

• Fix an edge case where the Dart VM could hang when shutting down when requests were in flight.

• Fix a race condition where the embedded host could fail to shut down if it was closed around the same time a new compilation was started.

• Fix a bug where parse-time deprecation warnings could not be controlled by the deprecation options in some circumstances.
