The update to SteamOS 3.7.15 for the Steam Deck has been released in the "stable"-channel.

Among other things, experimental Wake-on-Bluetooth support for Steam Deck LCD has been reactivated, including support for LE peripherals.
This means that it should now be possible to wake up the Steam Deck with an Xbox controller, for example.
