The main changes concern Big Picture mode. Fixed a bug where button icons were not updated when connecting a new controller. Now the interface instantly recognizes Xbox, PlayStation and other manufacturers' gamepads, and support for the wired Nintendo Switch 2 controller has been restored.
The update fixed serious issues that caused games with DRM protection to crash, including Mafia II and Football Manager 2012, and also fixed bugs that caused incorrect operation of vibration and feedback on gamepads and steering wheels, as well as VPN issues.
In addition, chat and library have been improved: game filters have become clearer, and friend management has become safer by disabling direct messages in public chats by default.
The update is downloaded automatically when Steam is launched.
