Release Notes

sass/dart-sass (sass)

v1.78.0

Compare Source

• 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.

v1.77.8

Compare Source

• No user-visible changes.

v1.77.7

Compare Source

• Declarations that appear after nested rules are deprecated, because the
  semantics Sass has historically used are different from the semantics
  specified by CSS. In the future, Sass will adopt the standard CSS semantics.

  See the Sass website for details.

• Potentially breaking bug fix: // in certain places such as unknown
  at-rule values was being preserved in the CSS output, leading to potentially
  invalid CSS. It's now properly parsed as a silent comment and omitted from the
  CSS output.

v1.77.6

Compare Source

• Fix a few cases where comments and occasionally even whitespace wasn't allowed
  between the end of Sass statements and the following semicolon.

v1.77.5

Compare Source

• Fully trim redundant selectors generated by @extend.

v1.77.4

Compare Source

Embedded Sass

• Support passing Version input for fatalDeprecations as string over
  embedded protocol.

• Fix a bug in the JS Embedded Host where Version could be incorrectly accepted
  as input for silenceDeprecations and futureDeprecations in pure JS.

v1.77.3

Compare Source

Dart API

• Deprecation.duplicateVariableFlags has been deprecated and replaced with
  Deprecation.duplicateVarFlags to make it consistent with the
  duplicate-var-flags name used on the command line and in the JS API.

v1.77.2

Compare Source

• Don't emit deprecation warnings for functions and mixins beginning with __.

• Allow user-defined functions whose names begin with _ and otherwise look
  like vendor-prefixed functions with special CSS syntax.

Command-Line Interface

• Properly handle the --silence-deprecation flag.

• Handle the --fatal-deprecation and --future-deprecation flags for
  --interactive mode.

v1.77.1

Compare Source

• Fix a crash that could come up with importers in certain contexts.

v1.77.0

Compare Source

• Don't throw errors for at-rules in keyframe blocks.

v1.76.0

Compare Source

• Throw errors for misplaced statements in keyframe blocks.

• Mixins and functions whose names begin with -- are now deprecated for
  forwards-compatibility with the in-progress CSS functions and mixins spec.
  This deprecation is named css-function-mixin.

v1.75.0

Compare Source

• Fix a bug in which stylesheet canonicalization could be cached incorrectly
  when custom importers or the Node.js package importer made decisions based on
  the URL of the containing stylesheet.

JS API

• Allow importer to be passed without url in StringOptionsWithImporter.
