Just hours ago Valve announced the new Steam Controller along with the Steam Frame VR headset and new Steam Machine. While these new Steam hardware products won't be available until early 2026, Valve has just-now upstreamed support for the new Steam Controller to the SDL3 library.

The Simple DirectMedia Library (SDL) is important to Valve's Steam runtime and used by many games for cross-platform hardware/software abstractions. In ensuring good support ahead of the new Steam Controller's retail availability and seeing that it makes it into the next SDL3 update, today that new Steam Controller support is already upstreamed to SDL Git.
