• Glasshouse is confirmed on webOS 2: a 2015 49LF632V joins the tested TVs. On TVs as old as webOS 2 and 3, LG's settings (backlight, picture mode, energy saving and others) now work, where the settings service still has its older name (#663, thanks @AlexNaga). On webOS 2, setting the clock from a time server and updating Glasshouse from the dashboard now work too (#681).
• The docs name webOS versions as the TV reports them (webOS 9, webOS 10), with LG's year names (webOS 24, webOS 25) beside them, and Tested TVs explains the two (#681).
• The Apps screenshot in the docs shows the Home screen layout section (#679).
