Another round of Steam Client Beta updates are here with Steam Deck and Desktop PC seeing lots of improvements and bug fixes, and it's especially nice for people using Bluetooth on Steam Deck.
Steam Deck Specific changes:
Show battery information for connected Bluetooth devices under Settings->Bluetooth and in the Quick Access menu.
Added a per-device toggle to Settings->Bluetooth that controls whether a device is allowed to wake Steam Deck from sleep.
Fixed a bug that would cause the UI to show stale data for Bluetooth devices.
