+### 3. Legacy v2 routes removed
+
+Only relevant if you use the `enableLegacyRoutes` option.
+
+Im v2 you could query feature toggles on `/api/features`. This was deprecated in v4 and we introduced two different endpoints (`/api/admin/features` and `/api/client/features`) to be able to optimize performance and security. In v3 you could still enable the legacy routes via the `enableLegacyRoutes` option. This was removed in v4.

 ## Upgrading from v2.x to v3.x
 
 The notable change introduced in Unleash v3.x is a strict separation of API paths for client requests and admin requests. This makes it easier to implement different authentication mechanisms for the admin UI and all unleash-clients. You can read more about [securing unleash](https://github.com/Unleash/unleash/blob/master/docs/securing-unleash.md).
