+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [3.0.0] - 2025-12-19
+
+### Changed - BREAKING
+- **Migrated from node-sass to dart-sass** - Modern Sass compiler
+- **Converted to Sass module system** - All `@import` statements replaced with `@use`/`@forward`
+- **Replaced Grunt with npm scripts** - Simpler, faster build system
+- **Modern Sass functions** - Using `sass:color`, `sass:map`, `sass:math` modules
+- Files now use `@use` instead of globals - may affect custom builds
+
+### Added
+- Modern package exports configuration
+- `.editorconfig` for consistent formatting
+- `.nvmrc` for Node version management
+- Comprehensive keywords for better discoverability
+
+### Fixed
+- All Sass deprecation warnings eliminated
+- 42 security vulnerabilities fixed (98% fewer dependencies)
+- Compatibility with Node.js 22+
+
+### Removed
+- Grunt and all Grunt plugins
+- `npm-shrinkwrap.json` (using package-lock.json instead)
+- Legacy node-sass dependencies
+
+## [2.11.2] and earlier
+See [release-notes/](./release-notes/) for historical releases.
