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.
--watch flag will now track loads through calls to meta.load-css() as long as their URLs are literal strings without any interpolation.See the full changelog for changes in earlier releases.

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

To install Sass 1.56.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.
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.
sassIndex with units to Value.sassIndexToListIndex(). This will be an error in Dart Sass 2.0.0.Importer results now validate whether contents is actually a string type.
Importer result argument errors are now rendered correctly.
See the full changelog for changes in earlier releases.
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 operation…
To install Sass 1.55.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.
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.
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.
See the full changelog for changes in earlier releases.

To install Sass 1.54.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.
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.
fakeFromImport() function for testing custom importers that use AsyncImporter.fromImport.Add a charset option that controls whether or not Sass emits a @charset/BOM for non-ASCII stylesheets.

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.
SassNumber.assertUnit() and SassNumber.assertNoUnits() now correctly return the number called on when it passes the assertion.See the full changelog for changes in earlier releases.

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

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.
To install Sass 1.45.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.
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 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.

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.See the full changelog for changes in earlier releases.

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.
SassCalculation.plus() now allows SassString arguments.See the full changelog for changes in earlier releases.

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.

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.
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.
