 ## Release notes
 
+### [0.1.0]
+
+- BREAKING CHANGE: the package has been migrated from TypeScript to
+  JavaScript + JsDocs for types. In this migration I've decided to make the
+  package ESM only so `require` would fail to load the lib. The new flag
+  `--experimental-require-module` can be used to load the lib if your app
+  is in `commonjs` format. Checkout [the docs](https://nodejs.org/docs/latest/api/modules.html#loading-ecmascript-modules-using-require).
+- Embed the parser into the lib
+- Add `intersection` API
