• Hiding home screen system apps is now an experimental feature on every TV: off by default, and turned on under Server → Experimental features. The app manager restart it needs at start-up has been followed by a black picture or lost sound that only a full reboot clears (#366). A TV where it was already running keeps it.
• Custom screen savers on webOS 10 and later are turned on from the same section, as well as with allowOnWebos10 in config.json.
• The README's Known issues section is now Experimental features, describing both and what to send if the picture or sound goes.
