+### UnifiedPush configuration
+
+Habitica Self-Host can now deliver UnifiedPush notifications. Devices that register with `type: "unifiedpush"` will post to their configured endpoints. If your mobile app supplies a relative registration ID, set `PUSH_CONFIGS_UNIFIEDPUSH_URL` to the base URL of your UnifiedPush distributor so the server can resolve the full endpoint URL. Use `PUSH_CONFIGS_UNIFIEDPUSH_AUTHORIZATION` when the distributor requires an Authorization header (for example, `Bearer <token>`). The `/api/v3/user/push-devices/test` endpoint now sends a default "Test Successful" notification so you can verify configuration quickly.

 > [!IMPORTANT]
 > If you are planning to run the Habitica containers on a Raspberry Pi 4, you might not be able to use `mongo:latest` (see [issue 20](https://github.com/awinterstein/habitica/issues/20)). In this case you can try to use `mongo:bionic` instead.
