+## Release v0.1
+
+Initial public preview (v0.1) — a minimal, working RadioPlayer experience:
+
+- Custom CAF Receiver UI (HTML/CSS/JS) in `receiver/` with branded artwork and playback status.
+- Plays LIVE stream: `https://live.radio1.si/Radio1MB` (contentType: `audio/mpeg`, streamType: `LIVE`).
+- Desktop sidecar (`sidecar/index.js`) launches the Default Media Receiver and sends LOAD commands; launch flow now retries if the device reports `NOT_ALLOWED` by stopping existing sessions first.
+
+Included receiver files:
+
+- `receiver/index.html`
+- `receiver/receiver.js` (CAF Receiver initialization + LOAD interceptor for LIVE metadata)
+- `receiver/styles.css`
+- `receiver/assets/logo.svg`
+
+Quick testing notes
+
+- The receiver must be served over HTTPS for Cast devices to load it. For quick local testing you can use `mkcert` + a static HTTPS server:
+
+```bash
+# create local certs
+mkcert -install
+mkcert localhost
+
+# serve the receiver folder over HTTPS
+npx http-server receiver -p 8443 -S -C localhost.pem -K localhost-key.pem
+```
+
+- Use the Default Media Receiver App ID while developing, or register a Custom Receiver App in the Cast Developer Console and point its URL to your hosted `index.html` for production.
+
+Sidecar / troubleshoot
+
+- If a Cast launch fails with `NOT_ALLOWED`, the sidecar will now attempt to stop any existing sessions on the device and retry the launch (best-effort). Check sidecar logs for `Launch NOT_ALLOWED` and subsequent retry attempts.
+- Note: the sidecar uses `castv2-client` (not the official Google sender SDK). Group/stereo behavior may vary across device types — for full sender capabilities consider adding an official sender implementation.
