Release Notes

sass/dart-sass (sass)

v1.72.0

Compare Source

• Support adjacent /s without whitespace in between when parsing plain CSS
  expressions.

• Allow the Node.js pkg: importer to load Sass stylesheets for package.json
exports field entries without extensions.

• When printing suggestions for variables, use underscores in variable names
  when the original usage used underscores.

JavaScript API

• Properly resolve pkg: imports with the Node.js package importer when
  arguments are passed to the JavaScript process.

v1.71.1

Compare Source

Command-Line Interface

• Ship the musl Linux release with the proper Dart executable.

JavaScript API

• Export the NodePackageImporter class in ESM mode.

• Allow NodePackageImporter to locate a default directory even when the
  entrypoint is an ESM module.

Dart API

• Make passing a null argument to NodePackageImporter() a static error rather
  than just a runtime error.

Embedded Sass

• In the JS Embedded Host, properly install the musl Linux embedded compiler
  when running on musl Linux.

v1.71.0

Compare Source

For more information about pkg: importers, see the
announcement on the Sass blog.

Command-Line Interface

• Add a --pkg-importer flag to enable built-in pkg: importers. Currently
  this only supports the Node.js package resolution algorithm, via
  --pkg-importer=node. For example, @use "pkg:bootstrap" will load
  node_modules/bootstrap/scss/bootstrap.scss.

JavaScript API

• Add a NodePackageImporter importer that can be passed to the importers
  option. This loads files using the pkg: URL scheme according to the Node.js
  package resolution algorithm. For example, @use "pkg:bootstrap" will load
  node_modules/bootstrap/scss/bootstrap.scss. The constructor takes a single
  optional argument, which indicates the base directory to use when locating
  node_modules directories. It defaults to
  path.dirname(require.main.filename).

Dart API

• Add a NodePackageImporter importer that can be passed to the importers
  option. This loads files using the pkg: URL scheme according to the Node.js
  package resolution algorithm. For example, @use "pkg:bootstrap" will load
  node_modules/bootstrap/scss/bootstrap.scss. The constructor takes a single
  argument, which indicates the base directory to use when locating
  node_modules directories.

v1.70.0

Compare Source

JavaScript API

• Add a sass.initCompiler() function that returns a sass.Compiler object
  which supports compile() and compileString() methods with the same API as
  the global Sass object. On the Node.js embedded host, each sass.Compiler
  object uses a single long-lived subprocess, making compiling multiple
  stylesheets much more efficient.

• Add a sass.initAsyncCompiler() function that returns a sass.AsyncCompiler
  object which supports compileAsync() and compileStringAsync() methods with
  the same API as the global Sass object. On the Node.js embedded host, each
  sass.AsynCompiler object uses a single long-lived subprocess, making
  compiling multiple stylesheets much more efficient.

Embedded Sass

• Support the CompileRequest.silent field. This allows compilations with no
  logging to avoid unnecessary request/response cycles.

• The Dart Sass embedded compiler now reports its name as "dart-sass" rather
  than "Dart Sass", to match the JS API's info field.

v1.69.7

Compare Source

Embedded Sass

• In the JS Embedded Host, properly install the x64 Dart Sass executable on
  ARM64 Windows.

v1.69.6

Compare Source

• Produce better output for numbers with complex units in meta.inspect() and
  debugging messages.

• Escape U+007F DELETE when serializing strings.

• When generating CSS error messages to display in-browser, escape all code
  points that aren't in the US-ASCII region. Previously only code points U+0100
  LATIN CAPITAL LETTER A WITH MACRON were escaped.

• Provide official releases for musl LibC and for Android.

• Don't crash when running meta.apply() in asynchronous mode.

JS API

• Fix a bug where certain exceptions could produce SourceSpans that didn't
  follow the documented SourceSpan API.

v1.69.5

Compare Source

JS API

• Compatibility with Node.js 21.0.0.

v1.69.4

Compare Source

• No user-visible changes.

v1.69.3

Compare Source

Embedded Sass

• Fix TypeScript type locations in package.json.

v1.69.2

Compare Source

JS API

• Fix a bug where Sass crashed when running in the browser if there was a global
  variable named process.

v1.69.1

Compare Source

• No user-visible changes.

v1.69.0

Compare Source

• Add a meta.get-mixin() function that returns a mixin as a first-class Sass
  value.

• Add a meta.apply() mixin that includes a mixin value.

• Add a meta.module-mixins() function which returns a map from mixin names in
  a module to the first-class mixins that belong to those names.

• Add a meta.accepts-content() function which returns whether or not a mixin
  value can take a content block.

• Add support for the relative color syntax from CSS Color 5. This syntax
  cannot be used to create Sass color values. It is always emitted as-is in the
  CSS output.

Dart API

• Deprecate Deprecation.calcInterp since it was never actually emitted as a
  deprecation.

Embedded Sass

• Fix a rare race condition where the embedded compiler could freeze when a
  protocol error was immediately followed by another request.

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.

v1.66.1

Compare Source

JS API

• Fix a bug where Sass compilation could crash in strict mode if passed a
  callback that threw a string, boolean, number, symbol, or bignum.

v1.66.0

Compare Source

• Breaking change: Drop support for the additional CSS calculations defined
  in CSS Values and Units 4. Custom Sass functions whose names overlapped with
  these new CSS functions were being parsed as CSS calculations instead, causing
  an unintentional breaking change outside our normal [compatibility policy] for
  CSS compatibility changes.

  Support will be added again in a future version, but only after Sass has
  emitted a deprecation warning for all functions that will break for at least
  three months prior to the breakage.

v1.65.1

Compare Source

• Update abs-percent deprecatedIn version to 1.65.0.

v1.65.0

Compare Source

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

• Deprecate explicitly passing the % unit to the global abs() function. In
  future releases, this will emit a CSS abs() function to be resolved by the
  browser. This deprecation is named abs-percent.

v1.64.2

Compare Source

• No user-visible changes.

v1.64.1

Compare Source

Embedded Sass

• Fix a bug where a valid SassCalculation.clamp() with less than 3 arguments
  would throw an error.

v1.64.0

Compare Source

• Comments that appear before or between @use and @forward rules are now
  emitted in source order as much as possible, instead of always being emitted
  after the CSS of all module dependencies.

• Fix a bug where an interpolation in a custom property name crashed if the file
  was loaded by a @use nested in an @import.

JavaScript API

• Add a new SassCalculation type that represents the calculation objects added
  in Dart Sass 1.40.0.

• Add Value.assertCalculation(), which returns the value if it's a
  SassCalculation and throws an error otherwise.

• Produce a better error message when an environment that supports some Node.js
  APIs loads the browser entrypoint but attempts to access the filesystem.

Embedded Sass

• Fix a bug where nested relative @imports failed to load when using the
  deprecated functions render or renderSync and those relative imports were
  loaded multiple times across different files.

v1.63.6

Compare Source

JavaScript API

• Fix import sass from 'sass' again after it was broken in the last release.

Embedded Sass

• Fix the exports declaration in package.json.

v1.63.5

Compare Source

JavaScript API

• Fix a bug where loading the package through both CJS require() and ESM
  import could crash on Node.js.

Embedded Sass

• Fix a deadlock when running at high concurrency on 32-bit systems.

• Fix a race condition where the embedded compiler could deadlock or crash if a
  compilation ID was reused immediately after the compilation completed.

v1.63.4

Compare Source

JavaScript API

• Re-enable support for import sass from 'sass' when loading the package from
  an ESM module in Node.js. However, this syntax is now deprecated; ESM users
  should use import * as sass from 'sass' instead.

  On the browser and other ESM-only platforms, only import * as sass from 'sass' is supported.

• Properly export the legacy API values TRUE, FALSE, NULL, and types from
  the ECMAScript module API.

Embedded Sass

• Fix a race condition where closing standard input while requests are in-flight
  could sometimes cause the process to hang rather than shutting down
  gracefully.

• Properly include the root stylesheet's URL in the set of loaded URLs when it
  fails to parse.

v1.63.3

Compare Source

JavaScript API

• Fix loading Sass as an ECMAScript module on Node.js.

v1.63.2

Compare Source

• No user-visible changes.

v1.63.1

Compare Source

• No user-visible changes.

v1.63.0

Compare Source

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.

v1.62.1

Compare Source

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

v1.62.0

Compare Source

• 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.

v1.61.0

Compare Source

• 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.

v1.60.0

Compare Source

• 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.

v1.59.3

Compare Source

• 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.

v1.59.2

Compare Source

• No user-visible changes.

v1.59.1

Compare Source

• No user-visible changes.

v1.59.0

Compare Source

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.

v1.58.3

Compare Source

• No user-visible changes.

v1.58.2

Compare Source

Command Line Interface

• Add a timestamp to messages printed in --watch mode.

• Print better calc()-based suggestions for /-as-division expression that
  contain calculation-incompatible constructs like unary minus.

v1.58.1

Compare Source

• Emit a unitless hue when serializing hsl() colors. The deg unit is
  incompatible with IE, and while that officially falls outside our
  compatibility policy, it's better to lean towards greater compatibility.

v1.58.0

Compare Source

• Remove sourcemap comments from Sass sources. The generated sourcemap comment
  for the compiled CSS output remains unaffected.

• Fix a bug in @extend logic where certain selectors with three or more
  combinators were incorrectly considered superselectors of similar selectors
  with fewer combinators, causing them to be incorrectly trimmed from the
  output.

• Produce a better error message for a number with a leading + or -, a
  decimal point, but no digits.

• Produce a better error message for a nested property whose name starts with
  --.

• Fix a crash when a selector ends in an escaped backslash.

• Add the relative length units from CSS Values 4 and CSS Contain 3 as known
  units to validate bad computation in calc.

Command Line Interface

• The --watch flag will now track loads through calls to meta.load-css() as
  long as their URLs are literal strings without any interpolation.

v1.57.1

Compare Source

• No user-visible changes.

v1.57.0

Compare Source

• Add a split($string, $separator, $limit: null) function to sass:string
  that splits a string into separate substrings based on a separator string.

JavaScript API

• Potentially breaking bug fix: Custom functions in both the modern and
  legacy API now properly reject signatures with whitespace between the function
  name and parentheses.

• Custom functions in the legacy API now allow signatures with whitespace before
  the function name, to match a bug in Node Sass.

Dart API

• Potentially breaking bug fix: Callable.fromSignature() and
  AsyncCallable.fromSignature() now reject signatures with whitespace between
  the function name and parentheses.

v1.56.2

Compare Source

Embedded Sass

• The embedded compiler now supports version 1.2.0 of the embedded
  protocol.

v1.56.1

Compare Source

Embedded Sass

• Importer results now validate that contents is actually a string and whether
  sourceMapUrl is an absolute URL.

v1.56.0

Compare Source

• Potentially breaking change: To match the CSS spec, SassScript expressions
  beginning with not or ( are no longer supported at the beginning of
  parenthesized sections of media queries. For example,

  @​media (width >= 500px) and (not (grid))

  will now be emitted unchanged, instead of producing

  @​media (width >= 500px) and (false)

  See the Sass website for details.

• Potentially breaking bug fix: Angle units like rad or turn are now
  properly converted to equivalent deg values for hsl(), hsla(),
  adjust-hue(), color.adjust(), and color.change().

  See the Sass website for
  details.

• Fix indentation for selectors that span multiple lines in a @media query.

• Emit a deprecation warning when passing $alpha values with units to
  color.adjust() or color.change(). This will be an error in Dart Sass
  2.0.0.

  See the Sass website for
  details.

• Emit a deprecation warning when passing a $weight value with no units or
  with units other than % to color.mix(). This will be an error in Dart Sass
  2.0.0.

  See the Sass website for
  details.

• Emit a deprecation warning when passing $n values with units to list.nth()
  or list.set-nth(). This will be an error in Dart Sass 2.0.0.

  See the Sass website for
  details.

• Improve existing deprecation warnings to wrap /-as-division suggestions in
  calc() expressions.

• Properly mark the warning for passing numbers with units to random() as a
  deprecation warning.

• Fix a bug where @extend could behave unpredicatably when used along with
  meta.load-css() and shared modules that contained no CSS themselves but
  loaded CSS from other modules.

Dart API

• Emit a deprecation warning when passing a sassIndex with units to
  Value.sassIndexToListIndex(). This will be an error in Dart Sass 2.0.0.

JS API

• Importer results now validate whether contents is actually a string type.

• Importer result argument errors are now rendered correctly.

v1.55.0

Compare Source

• Potentially breaking bug fix: Sass numbers are now universally stored as
  64-bit floating-point numbers, rather than sometimes being stored as integers.
  This will generally make arithmetic with very large numbers more reliable and
  more consistent across platforms, but it does mean that numbers between nine
  quadrillion and nine quintillion will no longer be represented with full
  accuracy when compiling Sass on the Dart VM.

• Potentially breaking bug fix: Sass equality is now properly transitive.
  Two numbers are now considered equal (after doing unit conversions) if they
  round to the same 1e-11th. Previously, numbers were considered equal if they
  were within 1e-11 of one another, which led to some circumstances where $a == $b and $b == $c but $a != $b.

• Potentially breaking bug fix: Various functions in sass:math no longer
  treat floating-point numbers that are very close (but not identical) to
  integers as integers. Instead, these functions now follow the floating-point
  specification exactly. For example, math.pow(0.000000000001, -1) now returns
  1000000000000 instead of Infinity.

• Emit a deprecation warning for $a -$b and $a +$b, since these look like
  they could be unary operations but they're actually parsed as binary
  operations. Either explicitly write $a - $b or $a (-$b). See
  https://sass-lang.com/d/strict-unary for more details.

Dart API

• Add an optional argumentName parameter to SassScriptException() to make it
  easier to throw exceptions associated with particular argument names.

• Most APIs that previously returned num now return double. All APIs
  continue to accept num, although in Dart 2.0.0 these APIs will be changed
  to accept only double.

JS API

• Fix a bug in which certain warning spans would not have their properties
  accessible by the JS API.

v1.54.9

Compare Source

• Fix an incorrect span in certain @media query deprecation warnings.

v1.54.8

Compare Source

• No user-visible changes.

v1.54.7

Compare Source

• Add support for 32-bit ARM releases on Linux.

v1.54.6

Compare Source

• Fix a bug where a @media query could be incorrectly omitted from a
  stylesheet if it had multiple levels of nested @media queries within it
  and the inner queries were mergeable but the outer query was not.

v1.54.5

Compare Source

• Properly consider a ~ c to be a superselector of a ~ b ~ c and a + b + c.

• Properly consider b > c to be a superselector of a > b > c, and similarly
  for other combinators.

• Properly calculate specificity for selector pseudoclasses.

• Deprecate use of random() when $limit has units to make it explicit that
  random() currently ignores units. A future version will no longer ignore
  units.

• Don't throw an error when the same module is @forwarded multiple times
  through a configured module.

Embedded Sass

• Rather than downloading the embedded compiler for the local platform on
  install, the sass-embedded npm package now declares optional dependencies on
  platform-specific embedded compiler packages.

v1.54.4

Compare Source

• Improve error messages when passing incorrect units that are also
  out-of-bounds to various color functions.

v1.54.3

Compare Source

• Release a native ARM64 executable for Mac OS.

v1.54.2

Compare Source

• No user-visible changes.

v1.54.1

Compare Source

• When unifying selectors for @extend and selector.unify(), ensure that
  :root, :scope, :host, and :host-context only appear at the beginning
  of complex selectors.

v1.54.0

Compare Source

• Deprecate selectors with leading or trailing combinators, or with multiple
  combinators in a row. If they're included in style rules after nesting is
  resolved, Sass will now produce a deprecation warning and, in most cases, omit
  the selector. Leading and trailing combinators can still be freely used for
  nesting purposes.

  See https://sass-lang.com/d/bogus-combinators for more details.

• Add partial support for new media query syntax from Media Queries Level 4. The
  only exception are logical operations nested within parentheses, as these were
  previously interpreted differently as SassScript expressions.

  A parenthesized media condition that begins with not or an opening
  parenthesis now produces a deprecation warning. In a future release, these
  will be interpreted as plain CSS instead.

• Deprecate passing non-deg units to color.hwb()'s $hue argument.

• Fix a number of bugs when determining whether selectors with pseudo-elements
  are superselectors.

• Treat * as a superselector of all selectors.

Dart API

• Add a top-level fakeFromImport() function for testing custom importers
  that use AsyncImporter.fromImport.

JS API

• Add a charset option that controls whether or not Sass emits a
  @charset/BOM for non-ASCII stylesheets.

• Fix Sass npm package types for TS 4.7+ Node16 and NodeNext module resolution.

v1.53.0

Compare Source

• Add support for calling var() with an empty second argument, such as
  var(--side, ).

JS API

• Fix a bug where meta.load-css() would sometimes resolve relative URLs
  incorrectly when called from a mixin using the legacy JS API.

Embedded Sass

• Respect npm's proxy settings when downloading the embedded Sass compiler.

v1.52.3

Compare Source

• Fix crash when trailing loud comments (/* ... */) appear twice in a row
  across two different imports which themselves imported the same file each.

v1.52.2

Compare Source

• Preserve location of trailing loud comments (/* ... */) instead of pushing
  the comment to the next line.

v1.52.1

Compare Source

Command Line Interface

• Fix a bug where --watch mode would close immediately in TTY mode. This was
  caused by our change to close --watch when stdin was closed outside of TTY
  mode, which has been reverted for now while we work on a fix.

v1.52.0

Compare Source

• Add support for arbitrary modifiers at the end of plain CSS imports, in
  addition to the existing supports() and media queries. Sass now allows any
  sequence of identifiers of functions after the URL of an import for forwards
  compatibility with future additions to the CSS spec.

• Fix an issue where source locations tracked through variable references could
  potentially become incorrect.

• Fix a bug where a loud comment in the source can break the source map when
  embedding the sources, when using the command-line interface or the legacy JS
  API.

JS API

• SassNumber.assertUnit() and SassNumber.assertNoUnits() now correctly
  return the number called on when it passes the assertion.

v1.51.0

Compare Source

• Potentially breaking change: Change the order of maps returned by
  map.deep-merge() to match those returned by map.merge(). All keys that
  appeared in the first map will now be listed first in the same order they
  appeared in that map, followed by any new keys added from the second map.

• Improve the string output of some AST nodes in error messages.

v1.50.1

Compare Source

Embedded Sass

• The JS embedded host and the embedded compiler will now properly avoid
  resolving imports relative to the current working directory unless '.' is
  passed as a load path.

• Fix a bug in the JS embedded host's implementation of the legacy JS API where
  imports that began with / could crash on Windows.

v1.50.0

Compare Source

• @extend now treats [:where()][:where()] the same as :is().

Command Line Interface

• Closing the standard input stream will now cause the --watch command to stop
  running.

Embedded Sass

• Fix a bug where the JS embedded host crashed when invoking a legacy importer
  after resolving a relative filesystem import.

• Improve error messages when returning non-Object values from legacy
  importers.

v1.49.11

Compare Source

• Add support for 64-bit ARM releases on Linux.

Embedded Sass

• The embedded compiler now correctly sets the id field for all
  OutboundMessages.

v1.49.10

Compare Source

• Quiet deps mode now silences compiler warnings in mixins and functions that
  are defined in dependencies even if they're invoked from application
  stylesheets.

• In expanded mode, Sass will now emit colors using rgb(), rbga(), hsl(),
  and hsla() function notation if they were defined using the corresponding
  notation. As per our browser support policy, this change was only done once
  95% of browsers were confirmed to support this output format, and so is not
  considered a breaking change.

  Note that this output format is intended for human readability and not for
  interoperability with other tools. As always, Sass targets the CSS
  specification, and any tool that consumes Sass's output should parse all
  colors that are supported by the CSS spec.

• Fix a bug in which a color written using the four- or eight-digit hex format
  could be emitted as a hex color rather than a format with higher browser
  compatibility.

• Calculations are no longer simplified within supports declarations

v1.49.9

Compare Source

Embedded Sass

• Fixed a bug where the legacy API could crash when passed an empty importer
  list.

v1.49.8

• Potentially breaking bug fix: Match the specification of the new JS API by
  passing undefined rather than null to Logger.warn() for an unset span.

TypeScript Declarations

• Add a declaration for the LegacyPluginThis.options.context field.

• Update the definition of LegacyAsyncFunction to include explicit definitions
  with zero through six arguments before the done parameter. This makes it
  possible for TypeScript users to pass in callbacks that take a specific number
  of arguments, rather than having to declare a callback that takes an arbitrary
  number.

• Add a declaration for types.Error, a legacy API class that can be returned
  by asynchronous functions to signal asynchronous errors.

• Add a LegacyAsyncFunctionDone type for the done callback that's passed to
  LegacyAsyncFunction.

  parameter for new SassArgumentList() to ',' rather than null. This
  matches the API specification.

v1.45.1

Compare Source

• Potentially breaking bug fix: Properly parse custom properties in
  @supports conditions. Note that this means that SassScript expressions on
  the right-hand side of custom property @supports queries now need to be

• Potentially breaking bug fix: Fix a bug where inspect() was not
  properly printing nested, empty, bracketed lists.

v1.45.0

JS API

This release includes an entirely new JavaScript API, designed to be more
idiomatic, performant, and usable. The old API will continue to be supported
until Dart Sass 2.0.0, but it is now considered deprecated and should be avoided
for new code.

The new API includes:

• compile() and compileAsync() functions that take Sass file paths and
  return the result of compiling them to CSS. The async function returns a
  Promise rather than using a callback-based API.

• compileString() and compileStringAsync() functions that take a string of
  Sass source and compiles it to CSS. As above, the async function returns a
  Promise.

• A new importer API that more closely matches the Sass specification's logic
  for resolving loads. This makes it much easier for Sass to cache information
  across @import and @use rules, which substantially improves performance
  for applications that rely heavily on repeated @imports.

• A new custom function API, including much more usable JS representations of
  Sass value types complete with type-assertion functions, easy map and list
  lookups, and compatibility with the [immutable][immutable] package. Unlike in the
  legacy API, function callbacks now take one argument which contains an array
  of Sass values (rather than taking a separate JS argument for each Sass
  argument).

For full documentation of this API, please see the Sass website.

This release also adds TypeScript type definitions.

v1.44.0

Compare Source

• Suggest calc() as an alternative in /-as-division deprecation messages.

Dart API

• Add SassNumber.convert() and SassNumber.convertValue(). These work like
  SassNumber.coerce() and SassNumber.coerceValue(), except they don't treat
  unitless numbers as universally compatible.

• Fix a bug where SassNumber.coerceToMatch() and
  SassNumber.coerceValueToMatch() wouldn't coerce single-unit numbers to
  match unitless numbers.

v1.43.5

Compare Source

• Fix a bug where calculations with different operators were incorrectly
  considered equal.

• Properly parse attribute selectors with empty namespaces.

JS API

• Print more detailed JS stack traces. This is mostly useful for the Sass team's
  own debugging purposes.

v1.43.4

Compare Source

JS API

• Fix a bug where the logger option was ignored for the render() function.

v1.43.3

Compare Source

• Improve performance.

v1.43.2

Compare Source

• Improve the error message when the default namespace of a @use rule is not
  a valid identifier.

v1.42.1

Compare Source

• Fix a bug where Sass variables and function calls in calculations weren't
  being resolved correctly if there was a parenthesized interpolation elsewhere
  in the file.

v1.42.0

Compare Source

• min() and max() expressions are once again parsed as calculations as long
  as they contain only syntax that's allowed in calculation expressions. To
  avoid the backwards-compatibility issues that were present in 1.40.0, they now
  allow unitless numbers to be mixed with numbers with units just like the
  global min() and max() functions. Similarly, + and - operations within
  min() and max() functions allow unitless numbers to be mixed with numbers
  with units.

v1.41.1

Compare Source

• Preserve parentheses around var() functions in calculations, because they
  could potentially be replaced with sub-expressions that might need to be
  parenthesized.

v1.41.0

Compare Source

• Calculation values can now be combined with strings using the + operator.
  This was an error in 1.40.0, but this broke stylesheets that were relying on
  $value + "" expressions to generically convert values to strings. (Note that
  the Sass team recommends the use of "#{$value}" or inspect($value) for
  that use-case.)

• The selector.unify() function now correctly returns null when one selector
  is a :host or :host-context and the other is a selector that's guaranteed
  to be within the current shadow DOM. The @extend logic has been updated
  accordingly as well.

• Fix a bug where extra whitespace in min(), max(), clamp(), and calc()
  expressions could cause bogus parse errors.

• Fix a bug where the right-hand operand of a - in a calculation could
  incorrectly be stripped of parentheses.

Dart API

• SassCalculation.plus() now allows SassString arguments.

v1.40.1

Compare Source

• Potentially breaking bug fix: min() and max() expressions outside of
  calculations now behave the same way they did in 1.39.2, returning unquoted
  strings if they contain no Sass-specific features and calling the global
  min() and max() functions otherwise. Within calculations, they continue to
  behave how they did in 1.40.0.

  This fixes an unintended breaking change added in 1.40.0, wherein passing a
  unitless number and a number without units to min() or max() now produces
  an error. Since this breakage affects a major Sass library, we're temporarily
  reverting support for min() and max() calculations while we work on
  designing a longer-term fix.

v1.40.0

Compare Source

• Add support for first-class calc() expressions (as well as clamp() and
  plain-CSS min() and max()). This means:

  • calc() expressions will be parsed more thoroughly, and errors will be
    highlighted where they weren't before. This may break your stylesheets,
    but only if they were already producing broken CSS.

  • calc() expressions will be simplified where possible, and may even return
    numbers if they can be simplified away entirely.

  • calc() expressions that can't be simplified to numbers return a new data
    type known as "calculations".

  • Sass variables and functions can now be used in calc() expressions.

  • New functions meta.calc-name() and meta.calc-args() can now inspect
    calculations.

Dart API

• Add a new value type, SassCalculation, that represents calculations.

• Add new CalculationOperation, CalculationOperator, and
  CalculationInterpolation types to represent types of arguments that may
  exist as part of a calculation.

• Add a new Value.assertCalculation() method.

• Add a new Number.hasCompatibleUnits() method.

v1.39.2

Compare Source

• Fix a bug where configuring with @use ... with would throw an error when
  that variable was defined in a module that also contained @forward ... with.

v1.39.1

Compare Source

• Partial fix for a bug where @at-root does not work properly in nested
  imports that contain @use rules. If the only @use rules in the nested
  import are for built-in modules, @at-root should now work properly.

v1.39.0

Compare Source

JS API

• Add a charset option that controls whether or not Sass emits a
  @charset/BOM for non-ASCII stylesheets.

v1.38.2

Compare Source

• No user-visible changes

v1.38.1

Compare Source

• No user-visible changes

v1.38.0

Compare Source

• In expanded mode, emit characters in Unicode private-use areas as escape
  sequences rather than literal characters.

• Fix a bug where quotes would be omitted for an attribute selector whose value
  was a single backslash.

• Properly consider numbers that begin with . as "plain CSS" for the purposes
  of parsing plain-CSS min() and max() functions.

• Allow if to be used as an unquoted string.

• Properly parse backslash escapes within url() expressions.

• Fix a couple bugs where @extends could be marked as unsatisfied when
  multiple identical @extends extended selectors across @use rules.

Command Line Interface

• Strip CRLF newlines from snippets of the original stylesheet that are included
  in the output when an error occurs.

JS API

• Don't crash when a Windows path is returned by a custom Node importer at the
  same time as file contents.

• Don't crash when an error occurs in a stylesheet loaded via a custom importer
  with a custom URL scheme.

Dart API

• Add a SassArgumentList.keywordsWithoutMarking getter to access the keyword
  arguments of an argument list without marking them accessed.

v1.37.5
