 ## Unreleased
 
+### `react` and `react-dom` is no longer added to [`resolve.dedupe`](https://vite.dev/config/#resolve-dedupe) automatically
+
+Adding values to `resolve.dedupe` will force Vite to resolve them in a different way than Node.js does, which is confusing and may not be expected. This plugin no longer adds `react` and `react-dom` to `resolve.dedupe` automatically.
+
+If you encounter an error after upgrading, check the `dependencies` / `devDependencies` in `package.json` and the package manager's configuration. If you want the previous behavior, you can add `react` and `react-dom` to `resolve.dedupe` manually.
