SteamOS 3.7.25, aşağıdaki değişikliklerle birlikte tüm kullanıcılar için yayınlandı:

Genel

• Güvenlik ve kararlılık güncellemeleri yapıldı.

We have just shipped an updated Steam Deck Client to the Preview/Beta channel.

General

• Fixed an issue where the Steam Workshop would download an older version of an item if there were multiple versions of the item that were marked valid for game beta branch the user opted into.

• Fixed Steam html surfaces failing to render in some games (e.g. motd in Team Fortress 2).

Steam Input

• Fixed FlyDigi Vader 5 Pro in enhanced mode

• Steam Controller: Triggers and Grip Sense Activators now pulse the Rumble Haptics instead of Touchpad Haptics

• Steam Controller: if Grip Sense is used with an Activator slot, or as one of the Gyro Enable Buttons, default Haptics Level to low. This is to help confirm activation in the absence of true physical response. To disable, set the Haptics setting to "Off" in Grip Sense activator settings, or if used as a Gyro Enable Button, set Haptics to "Off" in the Gyro mode settings.

• Fix: "Reset Camera To Horizon" action was inconsistent in different engines - turn commands chunked into 2 to improve consistency.

• Fix: Quick Settings Left Trackpad points to correct settings, instead of toward Gyro.

• Steam Controller: Minor improvement to gyro micro stutter (ignore clone packets)

• Gyro to Joystick Camera: Defaulted Gyro Deadzone Speed and Gyro Precision Speed to 0 to aide tuning the correct Minimum Joystick Output - these settings would swallow the micro movements needed to check the minimum response to gyro movements. Also: added Minimum Joystick Output slider on the Configurator Quick Settings list.

• Fixed not being able to use Grip Sense to activate Touch Menus.

Steam Controller Firmware

• Additional fixes for trackpad 'dead zone' issues experienced by some Steam Controllers.

• Fixed IMU failures when using extended rumble.
