Valve just released the next huge update for SteamOS into the preview branch for testing before heading to the Beta and Stable branches for everyone! SteamOS 3.7.0 is a massive one, and updates a lot of the operating system's core components, new controller support, and the beginnings of support for non-Steam Deck handhelds.

The biggest parts of the update are right at the top, with a new Arch Linux base, updated Linux Kernel, and updates to the graphics driver. The graphics driver update is especially great to see because that can include some nice performance enhancements and fixes for some of the newest games. There's only so much it can do, due to the Deck's limited hardware capabilities, but it's still awesome.

The biggest visible change will most likely be everything Desktop related. KDE Plasma has been updated to 6.2.5, which includes some big changes to the Desktop mode. There are new Overview effects, The Cube Effect has returned, partial HDR support, new wallpapers, overhauled looks for some default programs, reorganized settings, Plasma Search is faster and you can customize how search results are ordered, and much more. We also get KDE Filelight installed by default, which can be used to find out what is taking up so much space on your Deck, and swapping between Desktop and Game mode is faster.

But that's not all! Surround Sound is now working perfectly, but it is restricted to Desktop Mode. Bluetooth controllers can now wake up Steam Deck LCD units from sleep, the battery level display for Bluetooth device is now supported, there is support for the Proteus Byowave controller, and we have AMD P-State CPU Frequency control. And yes, with this SteamOS update, we officially have the beginning of support for handhelds outside of the Steam Deck, most likely starting with the Lenovo Legion Go S.

You can download the update yourself in the System Settings on the Steam Deck. Make sure your update channel is set to Preview. With this coming, we will most likely see SteamOS 3.7.0 rolled out into stable within a month, which is extremely exciting!
