We have just shipped an updated Steam Deck Client to the Preview/Beta channel.
Note: This update was re-released with the following additional changes:
Fixed a rare case that could result in multiple prompts to install the same update.
Fixed a rare case that could result in re-triggering the out of box wizard.
General
Added in-game keyboard shortcuts to open the Main Menu and Quick Access Menu.
Default Main Menu hotkey: Shift+Tab
Default Quick Access Menu hotkey: Ctrl+Shift+Tab
Customizable in Settings->In Game
Improved steam client update installation speed. In some pathological cases this operation could take minutes to complete, when the expected completion time is seconds.
Fixed events showing blurred images in the library for games with adult content.
