**Valve's SteamOS 3.8 Update Brings Long-Awaited Features and Support for Steam Machine** Valve has released SteamOS 3.8.0 in preview, marking a significant update for the operating system. The latest version comes with long-awaited features and support for various handheld devices, including the upcoming Steam Machine living room gaming PC. One of the most notable additions is genuine hibernation and "memory power down" modes for the Steam Deck's LCD model, which should help extend battery life when the device is idle or powered off. This feature had been requested by users, particularly those who prefer to use their Steam Deck as a handheld console. Additionally, Valve has added a setting in its gaming mode to allow users to use their Bluetooth headset microphones, a feature that was previously available in the Linux desktop mode. The update also includes various improvements for the Linux desktop modes, which are expected to be useful for users who plan to use their Steam Machine or handheld device plugged into a TV or monitor. These features include desktop HDR, VRR display support, per-display scaling, and an upgrade to KDE Plasma 6.4.3. Furthermore, the Steam Machine or handheld device can now detect the number of audio channels available over HDMI to enable surround sound. The update also brings several new features and improvements for non-Deck devices. Long-pressing the power button should now work across a wide variety of devices to power off, restart, or switch to the desktop mode. Users of the Xbox Ally series can now change their processor's power modes, and night mode and screen color settings should work on AMD Z2 Extreme handhelds. The update also includes improved video memory management with discrete GPU platforms, the ability to limit battery charging on Lenovo Legion Go handhelds, and fixes for washed-out colors on Zotac and OneXPlayer handhelds with OLED displays. The changelog for SteamOS 3.8.0 is extensive, and users are encouraged to review it in full to discover all the new features and improvements. Some of the notable devices supported by the update include Microsoft and Asus' Xbox Ally series, the Lenovo Legion Go 2, the OneXPlayer X1, MSI, GPD, Anbernic, OrangePi, and Zotac.
