Release Notes

sass/dart-sass (sass)

v1.77.7

Compare Source

• Declarations that appear after nested rules are deprecated, because the
  semantics Sass has historically used are different from the semantics
  specified by CSS. In the future, Sass will adopt the standard CSS semantics.

  See the Sass website for details.

• Potentially breaking bug fix: // in certain places such as unknown
  at-rule values was being preserved in the CSS output, leading to potentially
  invalid CSS. It's now properly parsed as a silent comment and omitted from the
  CSS output.
