+## [0.38.0] - 2024-02-29
+
+## Breaking Changes
+
+-   Previously, when calling `redirectToAuth` with the `redirectBack` option, url fragments(hash) were stripped when redirecting back to the previous page after authentication. This issue has been fixed, and url fragments are preserved along with the query params. For users who employed the workaround of overriding the `windowHandler.location.getSearch` function to include fragments, it is essential to remove that override before upgrading to this version.
+
 ## [0.37.1] - 2024-02-26
 
 -   Fixes types argument in override functions to make `builder` non optional.

+# SuperTokens Demo app - with-hash-router
+
+This demo app shows you how to use SuperTokens with a frontend router that uses hash routing. This example in particular uses [react-router-dom](https://reactrouter.com/web/guides/quick-start) with hash router.
+
+The main idea is that we provide a custom `windowHandler` on the frontend's supertokens.init which will provide functions for getting the pathname, search and hash from the url.
+
+You can find the implementation of this custom handler in `/frontend/src/windowHandler.ts`. The function `getWindowHandler` that is exposed by this file is used in `supertokens.init` in `/frontend/src/config.ts`.
+
+You can start the demo app by running:
+
+```bash
+git clone https://github.com/supertokens/supertokens-auth-react
+cd supertokens-auth-react/examples/with-hash-router
+
+npm install
+
+npm run start
+```
