Changelog

2.0.2 – unreleased

Added

• Fix deprecations on PHP 8.5 (@cedric-anne)

2.0.1 – January 31, 2025

Fixed

• Fix the generation of inline source maps (@ArnaudLigny)

2.0.0 – December 23, 2024

This release is a full rewrite of the compiler. The new implementation is a port of dart-sass, making it spec-compliant and easier to update to support new Sass features. However this release does not implement Sass modules yet.

BC breaks

• The Compiler class is now final
• The LoggerInterface now expects more argument in its method signatures
• \ScssPhp\ScssPhp\OutputStyle is now an enum instead of a class with string constants.
• Compiler::setOutputStyle now expects an instance of the OutputStyle enum instead of a string.
• Deprecated methods of the compiler have been removed.

Deprecated

• Deprecate passing a path as string as the Compiler::compileString second argument. Either pass a URL or use Compiler::compileFile instead. (@stof)

Removed

• Remove support for color math in Sass expressions (@stof)
• Remove the CLI shipped in the package (@stof)
• Remove the scss.inc.php file. Use the autoloader generated by Composer instead. (@stof)
• Remove the cache system integrated in the compiler (@stof)
• Remove support for PHP < 8.1 (@stof)

Added

• Add support for PHP 8.4 (@stof)
• Add support for the Sass indented syntax (@stof)
• Add a representation of Sass values using PHP value objects (@stof)

Fixed

• Thanks to the rewrite, scssphp is now spec-compliant, fixing many issues (@stof)

Changed

• The message received by loggers no longer contains the location and stack trace. Loggers need to include them based on the provided argument depending on their formatting needs. (@stof)
• Custom functions can now be defined using the new representation of Sass values by using \ScssPhp\ScssPhp\Value\Value as return type. Untyped functions will still receive legacy values. (@stof)
