To install Sass 1.58.0, download one of the packages below and add it to your PATH, or see the Sass website for full installation instructions.

Changes

• 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.
