Release Notes

sass/dart-sass (sass)

v1.68.0

Compare Source

• Fix the source spans associated with the abs-percent deprecation.

JS API

• Non-filesystem importers can now set the nonCanonicalScheme field, which declares that one or more URL schemes (without :) will never be used for URLs returned by the canonicalize() method.

• Add a containingUrl field to the canonicalize() and findFileUrl() methods of importers, which is set to the canonical URL of the stylesheet that contains the current load. For filesystem importers, this is always set; for other importers, it's set only if the current load has no URL scheme, or if its URL scheme is declared as non-canonical by the importer.

Dart API

• Add AsyncImporter.isNonCanonicalScheme, which importers (async or sync) can use to indicate that a certain URL scheme will never be used for URLs returned by the canonicalize() method.

• Add AsyncImporter.containingUrl, which is set during calls to the canonicalize() method to the canonical URL of the stylesheet that contains the current load. This is set only if the current load has no URL scheme, or if its URL scheme is declared as non-canonical by the importer.

Embedded Sass

• The CalculationValue.interpolation field is deprecated and will be removed in a future version. It will no longer be set by the compiler, and if the host sets it it will be treated as equivalent to CalculationValue.string except that "(" and ")" will be added to the beginning and end of the string values.

• Properly include TypeScript types in the sass-embedded package.

v1.67.0

Compare Source

• All functions defined in CSS Values and Units 4 are now once again parsed as calculation objects: round(), mod(), rem(), sin(), cos(), tan(), asin(), acos(), atan(), atan2(), pow(), sqrt(), hypot(), log(), exp(), abs(), and sign().

  Unlike in 1.65.0, function calls are not locked into being parsed as calculations or plain Sass functions at parse-time. This means that user-defined functions will take precedence over CSS calculations of the same name. Although the function names calc() and clamp() are still forbidden, users may continue to freely define functions whose names overlap with other CSS calculations (including abs(), min(), max(), and round() whose names overlap with global Sass functions).

• Breaking change: As a consequence of the change in calculation parsing described above, calculation functions containing interpolation are now parsed more strictly than before. However, almost all interpolations that would have produced valid CSS will continue to work. The only exception is #{$variable}% which is not valid in Sass and is no longer valid in calculations. Instead of this, either use $variable directly and ensure it already has the % unit, or write ($variable * 1%).

• Potentially breaking bug fix: The importer used to load a given file is no longer used to load absolute URLs that appear in that file. This was unintented behavior that contradicted the Sass specification. Absolute URLs will now correctly be loaded only from the global importer list. This applies to the modern JS API, the Dart API, and the embedded protocol.

Embedded Sass

• Substantially improve the embedded compiler's performance when compiling many files or files that require many importer or function call round-trips with the embedded host.
