+## 2.0.0 (December 14, 2021)
 
+- Added `syntaxExtensions` option to specify syntax extensions, i.e. `sass` or/and `less`. For now **the plugin validates CSS only by default**
 - Added at-rule validation for name, prelude and descriptors
 - Added `atrules` option to extend or alter at-rule syntax definition dictionary or disable at-rule validation when `false` is passed as a value for the option
 - Added `ignoreAtrules` option to specify at-rule names which should not be validated
-- Added `syntaxExtensions` option to specify syntax extensions, i.e. `sass` or/and `less`
 - Used `isStandardSyntax*()` helpers from `stylelint` to reduce failures for non-standard syntax (e.g. Less or Sass)
 - Added support for Less & Sass namespaces, a value with such constructions are ignored now instead of failure (#39)
 - Added a column to mismatch error details
