We have just shipped an updated Steam Deck Client to the Preview/Beta channel.
General
Fixed regression causing certain client popup browser windows failing to load.
Steam Input
Analog Trigger Output is made available in the Trigger Mode select screen for better discoverability.
Joystick Mode settings: Added "Response Axis Style" to "Stick Response Curve" options. The Response Curves can be applied in a "Per Axis" or "Circular" fashion. Previously, Joystick Mode only supported "Per Axis" response curves. Generally, Circular is recommended, and is now default. The option will only appear when relevant - when "Stick Response Curve" is not set to "Linear".
