We have just shipped an updated Steam Deck Client to the Stable channel.

General

• Added notification settings for showing a toast and playing a sound when an achievement is unlocked.

This data will help us learn about game compatibility and improve Steam. This feature is currently in Beta with a focus on devices running SteamOS.

• When submitting feedback on whether you agree with a Deck Verified rating, if you disagree we'll now ask for the reason. Providing a reason is optional.

Steam Input

• Fixed a bug in Gyro To Joystick Deflection mode where a setting of 0 for Minimum Gyro Deflection, and any non zero Minimum Joystick Output would still result in zero output without a significant amount of gyro deflection.
