Hot on the heels of the SteamOS 3.8.26 Beta, Valve released SteamOS 3.9.0 Preview bringing some really massive changes to the system.
This is much more of a here be dragons type of release, because a fair amount of the software behind the scenes has seen major version changes. The Linux kernel has been bumped up to version 7.2 (SteamOS stable is on 6.16) which brings support for new hardware and improvements to existing hardware, and desktop mode will see quite a lot of general improvements too with KDE Plasma 6.7.3. -

SteamOS 3.9 adds preliminary hibernation support at the operating system level. Valve says the feature is not yet exposed through the Game Mode interface, so this is still under development rather than something most Steam Deck users can enable normally.
This follows earlier work on hibernation in SteamOS 3.8. Valve added preliminary hibernation support to the Steam Deck LCD BIOS with SteamOS 3.8.5, which we covered in May. SteamOS 3.9 now includes kernel changes for hibernation, including support for interrupting hibernate requests and fixes for several driver issues.
