Valve has released its November 11, 2026 Steam Client update, bringing the 64-bit Steam application to the stable channel on Linux alongside a new Steam Runtime container system. The update also introduces Steam Achievement Sets to all users, improves client startup performance, and delivers several fixes across Steam’s gaming features.
The Linux transition is one of the more significant technical changes in the release. Previously available through the Steam Client Beta beginning October 15, the 64-bit application is now included in Valve’s general client update, marking its move beyond beta testing.
The updated Linux client also runs inside a Steam Runtime container. According to Valve’s official release notes, this uses technology already employed by Steam games to provide a more consistent client experience across different Linux distributions. The change concerns the Steam application itself and does not mean that support for 32-bit games or their dependencies has been removed.
Valve has also redesigned the Steam updater interface and corrected an issue that prevented the updater window from appearing for some users. Linux-specific fixes address a crash when resuming from suspend and another crash when creating multiplayer lobbies in games using the ISteamNetworking interface, including Sons of the Forest.
Alongside these Linux improvements, Steam Achievement Sets have officially reached the stable client after their October beta introduction. The feature allows developers to organize achievements into separate groups for base games, downloadable content, and other additions.
Previously, adding new achievements to an existing game could affect the completion status of players who had already earned everything available. Achievement Sets address this by preserving completed sets even when developers introduce additional achievements or DLC.
Developers can also archive achievements or entire sets that are no longer obtainable, such as those associated with seasonal events. Players who previously earned those achievements retain their records, while unavailable achievements no longer prevent other users from reaching completion.
The redesigned achievements page combines overall game completion, individual set progress, achievement details, global statistics, and expanded filtering. Players can also compare their achievement progress with up to three friends.
The November 11 update includes another round of Steam startup performance improvements, following earlier optimizations. Valve has also addressed rare crashes, memory leaks affecting streaming and controller functionality, and an issue that could incorrectly display Steam Cloud synchronization conflicts in certain games.
Remote Play receives additional changes, including expanded HDR controls, brightness adjustment options, and HDR capture support when using PipeWire on desktop Linux. HDR support has also been restored for Steam Deck OLED streaming.
Other improvements include updated Steam Store search suggestions, better responsiveness in Big Picture Mode, fixes for friend notifications, and expanded Steam Input support.
The November 11 release brings together the Linux client’s 64-bit transition and several previously tested Steam features in a stable update distributed automatically through the Steam client.
