Changes

Command-Line Interface

• The --fatal-deprecation flag can now exclude deprecations that would otherwise be included by passing a version number. To exclude a deprecation, add - before its name. For example, --fatal-deprecation=1.107.0,-import includes all deprecations that were present in Dart Sass 1.107.0 except for the @import deprecation.

• The --fatal-deprecation flag now takes the special value dart-sass-2, which treats as fatal all deprecations that will become fatal in Dart Sass 2.0.0.

JavaScript API

• Options.fatalDeprecations can now take a DeprecationSelectorDifference object of the form {include: ..., except: ...}, where the include field lists deprecations to mark fatal (which can be version numbers) and the except field lists deprecations not to mark fatal. The except field takes precedence over include.

• Add a (non-enumerable) sass.deprecations.dartSass2 property which can be passed to Options.fatalDeprecations to mark as fatal exactly the deprecations that will become fatal in Dart Sass 2.0.0. This can be combined with other deprecations or used in a DeprecationSelectorDifference to modify exactly which deprecations it covers.

• Passing a version number beyond the current Dart Sass version to Options.fatalDeprecations is now deprecated. See the Sass website for details.

Dart API

• Add a Deprecation.dartSass2 property which returns exactly the set of deprecations that will become fatal in Dart Sass 2.0.0.

• Passing a version number beyond the current Dart Sass version to Deprecation.forVersion is now deprecated.

Embedded Protocol

• Add a CompileRequest.fatal_deprecation_except field which excludes deprecations from being considered fatal if they would have been enabled by CompileRequest.fatal_deprecation.
