Valve has released successive beta updates for the Steam client focusing on user interface enhancements and improved Linux compatibility.

An initial update introduced “Big Art Mode” for the Big Picture interface, which utilizes configurable slideshows of game art and screenshots for large screens. This release also added a personal calendar for tracking game events and provided technical refinements for Linux users, including bug fixes for Steam Input and enhanced stability for the Steam Overlay when using Proton or the Vulkan API.

A subsequent update further streamlined the Linux experience by automating the use of the Proton compatibility layer for Windows binary files registered as non-Steam games. This update also introduced a setting to disable screensavers during gameplay and addressed various bugs related to controller reordering, firmware stability, and playtime displays.
