1.23.3

• Fix a bug where selectors were being trimmed over-eagerly when @extend crossed module boundaries.

1.23.2

Command-Line Interface

• Fix a bug when compiling all Sass files in a directory where a CSS file could be compiled to its own location, creating an infinite loop in --watch mode.

• Properly compile CSS entrypoints in directories outside of --watch mode.

1.23.1

• Fix a bug preventing built-in modules from being loaded within a configured module.

• Fix a bug preventing an unconfigured module from being loaded from within two different configured modules.

• Fix a bug when meta.load-css() was used to load some files that included media queries.

• Allow saturate() in plain CSS files, since it can be used as a plain CSS filter function.

• Improve the error messages for trying to access functions like lighten() from the sass:color module.

1.23.0

• Launch the new Sass module system! This adds:

  • The @use rule, which loads Sass files as modules and makes their members available only in the current file, with automatic namespacing.

  • The @forward rule, which makes members of another Sass file available to stylesheets that @use the current file.

  • Built-in modules named sass:color, sass:list, sass:map, sass:math, sass:meta, sass:selector, and sass:string that provide access to all the built-in Sass functions you know and love, with automatic module namespaces.

  • The meta.load-css() mixin, which includes the CSS contents of a module loaded from a (potentially dynamic) URL.

  • The meta.module-variables() function, which provides access to the variables defined in a given module.

  • The meta.module-functions() function, which provides access to the functions defined in a given module.

  Check out the Sass blog for more information on the new module system. You can also use the new Sass migrator to automatically migrate your stylesheets to the new module system!

1.22.12

• Potentially breaking bug fix: character sequences consisting of two or more hyphens followed by a number (such as --123), or two or more hyphens on their own (such as --), are now parsed as identifiers in accordance with the CSS spec.

  The sequence -- was previously parsed as multiple applications of the - operator. Since this is unlikely to be used intentionally in practice, we consider this bug fix safe.

Command-Line Interface

• Fix a bug where changes in .css files would be ignored in --watch mode.

JavaScript API

• Allow underscore-separated custom functions to be defined.

• Improve the performance of Node.js compilation involving many @imports.

1.22.10

• Fix a bug in which get-function() would fail to find a dash-separated function when passed a function name with underscores.

1.22.9

• Include argument names when reporting range errors and selector parse errors.

• Avoid double Error: headers when reporting selector parse errors.

• Clarify the error message when the wrong number of positional arguments are passed along with a named argument.

JavaScript API

• Re-add support for Node Carbon (8.x).

1.22.7

• Restrict the supported versions of the Dart SDK to ^2.4.0.

1.22.6

• Potentially breaking bug fix: The keywords() function now converts underscore-separated argument names to hyphen-separated names. This matches LibSass's behavior, but not Ruby Sass's.

• Further improve performance for logic-heavy stylesheets.

• Improve a few error messages.

1.22.5

JavaScript API

• Improve performance for logic-heavy stylesheets.
