Release Notes

sass/dart-sass

v1.66.0

Compare Source

• Breaking change: Drop support for the additional CSS calculations defined in CSS Values and Units 4. Custom Sass functions whose names overlapped with these new CSS functions were being parsed as CSS calculations instead, causing an unintentional breaking change outside our normal [compatibility policy] for CSS compatibility changes.

  Support will be added again in a future version, but only after Sass has emitted a deprecation warning for all functions that will break for at least three months prior to the breakage.
