+- New: `parse` and `stringify` can now be imported as named exports when using
+  JavaScript modules. ([#243])
+- New: Browser bundles use more descriptive names (e.g. `dist/json5.umd.js` and
+  `dist/json5.esm.js`). Legacy `dist/index.*` names are deprecated, and will be
+  removed in the next major version. ([#243])
+- Fix: CommonJS and module exports in Node.js refer to the same instance.
+  ([#243])
