 ## Application Setup
 
-The web app is accessible at `http://SERVERIP:8088`. The server by default is available at `http://SERVERIP:EXTERNAL_SERVER_PORT/slserver`.
+The web app and the server are both accessible at `http://SERVERIP:8088`.
 
-Note: The server address is hardcoded to `http` as `https` is not recommended due to not working with external plex clients. When you reverse proxy, use `http` as the external proto for both webapp and server.

 ## Versions
 
+* **28.10.20:** - Update to v4. Env vars `EXTERNAL_URL`, `EXTERNAL_SERVER_PORT` and `AUTOJOIN_PASSWORD` are deprecated and no longer have any effect. Env vars `AUTOJOIN_ENABLED` and `AUTOJOIN_ROOM` are still working but will be removed in the future in favor of synclounge's built-in var `autojoin__room`. If you are reverse proxying, do not forget to update your proxy settings ([here](https://github.com/linuxserver/reverse-proxy-confs/blob/master/synclounge.subdomain.conf.sample) and [here](https://github.com/linuxserver/reverse-proxy-confs/blob/master/synclounge.subfolder.conf.sample)) as the server port and addresses are changed.
 * **11.10.20:** - Pin builds to upstream commit `6aecc9bd` while evaluating the breaking changes upstream.
 * **27.09.20:** - Updating the external repo endpoint.
 * **01.06.20:** - Rebasing to alpine 3.12.
