Valve and CodeWeavers have unleashed another update to Steam Play with Proton 4.11-7 releasing today.
Seems they're continuing to try and get gamepads/controllers into a good state, with "Major" improvements to how they handle hotplugging. More games should now see your gamepad when you plug it in after you start it. Additionally, there's improved support for Windows games built with Unity using the Rewired Unity plugin.
They also updated wine-mono which is now at version 4.9.3, this should hopefully improve font rendering and help fix some compatibility issues with Age of Wonders: Planetfall. Kingdom Come: Deliverance got a fix when launching and some VR games might no longer crash too.
As usual the latest Proton update will be available in the Steam client shortly if not already. You can find the changelog here.
