-- Fix #202 replace related issues.
-- Update dependencies
+## 2.4.0
 
-### 2.1.0
+- Modernized toolchain: migrated from Rollup/Babel to tsup/Bun for faster builds
+- Added comprehensive test suites with 100% code coverage
+- Fixed slugify to collapse consecutive separators (e.g., `hello---world` → `hello-world`)
+- Fixed slugify to properly strip leading/trailing separators
+- Replaced TSLint/Prettier with Biome for linting
+- Minimum Node.js requirement is now v20.0.0
+- Refactored utilities and added edge case handling
+- Added Vitest as modern test runner with jsdom environment for browser tests
 
-- Add `transliterate` as a global variable for browser builds. Keep `transl` for backward compatibility.
+## 2.2.0
 
-### 2.0.0
+- Fixed data issue (#229)
+- Added `fixChineseSpacing` option for improving performance with non-Chinese languages
+- Fixed replace-related issues (#202)
+- Updated dependencies
 
-- **CDN file structure changed**: [https://www.jsdelivr.com/package/npm/transliteration](https://www.jsdelivr.com/package/npm/transliteration)
-- The entire module had been refactored in Typescript, with big performance improvements as well as a reduced package size.
-- Better code quality. 100% unit tested.
-- `bower` support was dropped. Please use CDN or `webpack`/`rollup`.
-- As according to RFC 3986, more characters(`/a-zA-Z0-9-_.~/`) are kept as allowed characters in the result for `slugify`, and it is configurable.
-- Added `uppercase` as an option for `slugify`, if is set to `true` then the generated slug will be converted to uppercase letters.
-- Unknown characters will be transliterated as empty string by default, instead of a meaningless `[?]`.
+## 2.1.0
 
-### 1.6.6
+- Added `transliterate` as a global variable for browser builds (kept `transl` for backward compatibility)
 
-- Added support for `TypeScript`. #77

+- **Breaking**: CDN file structure changed — see [jsDelivr](https://www.jsdelivr.com/package/npm/transliteration)
+- Refactored entire module in TypeScript with significant performance improvements and reduced package size
+- Improved code quality with 100% unit test coverage
+- Dropped `bower` support — use CDN or bundlers like webpack/rollup instead

-- Minimum node requirement: 6.0+
+## 1.6.6
 
-### 1.0.0
+- Added TypeScript support (#77)
 
-- Code had been entirely refactored since version 1.0.0. Be careful when you plan to upgrade from v0.1.x or v0.2.x to v1.0.x
-- The `options` parameter of `transliterate` now is an `Object` (In 0.1.x it's a string `unknown`).
-- Added `transliterate.config` and `slugify.config`.
-- Unknown string will be transliterated as `[?]` instead of `?`.
-- In the browser, global variables have been changed to `window.transl` and `windnow.slugify`. Other global variables are removed.
