Valve has announced three things recently including multiple updates that are out now for the Steam Deck, plus a quick tease of what's to come for a Beta of SteamOS 3.4.

Firstly, a new SteamOS update is out now in the Stable and Beta channels that pulls these changes over from Preview:

There's also a Steam Deck Client Beta update out now for those in the Beta and Preview update channels with these changes:

On top of that and perhaps even more exciting, is that a Beta version of SteamOS 3.4 is on the way. Confirmed on Twitter by Valve developer Pierre-Loup Griffais, who mentioned it's being worked on right now and it will "contain an update to the Arch base". SteamOS basically uses a snapshot of Arch Linux, along with tweaks and changes that Valve do, so with SteamOS 3.4 we're likely to see an updated Linux kernel, updated KDE Plasma for desktop mode and a whole lot more updated software.
