A new Steam Deck Beta Client update was released yesterday with some new support and bug fixes. We now have support for the Malay language and GameCube rumble, while also fixing some bugs for action sets and virtual menus. The Steam Deck Client will also now run inside a Steam Runtime container, which should help provide a more consistent experience across the board.

You can download the updates yourself in the System Settings on the Steam Deck. Make sure your update channel is set to Beta or Preview for the beta update, while the stable update should just be available in any update channel.
