Release Notes

sass/dart-sass (sass)

v1.87.0

Compare Source

• Potentially breaking bug fix: When a plain CSS file with a top-level
  nesting selector & is loaded into a nested Sass context via
  meta.load-css() or @import, Sass now emits plain CSS nesting rather than
  incorrectly combining it with the parent selector using a descendant
  combinator.
