1.80.5

Embedded Host

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

1.80.4

• No user-visible changes.

1.80.3

• 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.

1.80.2

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

1.80.1

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

1.80.0

• @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.

1.79.6

• 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.
