We have just shipped an updated Steam Deck Client to the Preview/Beta channel.
General
Fixed a case where the 'Patch Notes' preview box in Settings->System would incorrectly show an event for the wrong channel. E.g. showing Beta Channel notes when the client is opted in to the Stable Channel.
Desktop Mode
Fixed incorrect UI scale being used when in Big Picture Mode.
Steam Input
Added support for both the wired and wireless versions of the PDP Afterglow Wave Controller for Nintendo Switch
Added support for Turtle Beach controllers for Nintendo Switch 2
Remote Play
Added 59.94 FPS as an available framerate limit
Reduced frame drops when the framerate limit is set to automatic
Fixed overloading the client video decoder when unlimited bandwidth is enabled
Steam Controller FW
Fixed an issue with occasional repeated button presses on the B Button
