* If you have installed manually by source the PlexMediaServer, it now has the ability to update itself through the settings' webpage
* If you are using amahi-plex it will auto update itself as so as the developers push the new version into amahiAmahi's repo. Don't try to update the amahi-plex web app although in the setting's webpage it will inform you that a new version of PlexServer Plex Media Server is available. Most probably it will fail or it will brake down break your system !!!
