Release Notes

sass/dart-sass (sass)

v1.81.0

Compare Source

• Fix a few cases where deprecation warnings weren't being emitted for global
  built-in functions whose names overlap with CSS calculations.

• Add support for the CSS round() calculation with a single argument, as long
  as that argument might be a unitless number.

v1.80.7

Compare Source

Embedded Host

• Don't treat 0 as undefined for the green and blue channels in the
  LegacyColor constructor.

v1.80.6

Compare Source

Command-Line Interface

• Make @parcel/watcher an optional dependency so this can still be installed
  on operating systems where it's unavailable.

v1.80.5

Compare Source

Embedded Host

• Don't produce phantom @import deprecations when using an importer with the
  legacy API.

v1.80.4

Compare Source

• No user-visible changes.

v1.80.3

Compare Source

• Fix a bug where @import url("...") would crash in plain CSS files.

• Improve consistency of how warnings are emitted by different parts of the
  compiler. This should result in minimal user-visible changes, but different
  types of warnings should now respond more reliably to flags like --quiet,
  --verbose, and --silence-deprecation.

v1.80.2

Compare Source

• Fix a bug where deprecation warnings were incorrectly emitted for the
  plain-CSS invert() function.

v1.80.1

Compare Source

• Fix a bug where repeated deprecation warnings were not automatically limited.

v1.80.0

Compare Source

• @import is now officially deprecated, as are global built-in functions that
  are available within built-in modules. See the Sass blog post for more
  details on the deprecation process.

Embedded Host

• Fix an error that would sometimes occur when deprecation warnings were
  emitted when using a custom importer with the legacy API.

v1.79.6

Compare Source

• Fix a bug where Sass would add an extra */ after loud comments with
  whitespace after an explicit */ in the indented syntax.

• Potentially breaking bug fix: Adding text after an explicit */ in the
  indented syntax is now an error, rather than silently generating invalid CSS.

Embedded Host

• Properly export the SassBoolean type.
