New framework, new foundation
The most impactful changes in this update aren’t immediately visible; much of the work went into changing how we share code across the Steam Desktop Client, Big Picture mode, and Steam Deck. These changes also means quicker implementation and iteration of new features. For example, many of the features in this update (like Notes in the overlay) are simultaneously shipping on Steam Deck because of the shared codebase.

Steam gets a fresh coat of paint
This update also brings targeted visual and usability improvements across Steam - we've gone through and updated dialogs, menus, fonts, and colors. The main Steam header and footer, Settings, and the Screenshot Manager are just a few examples of spots with refreshed UI.
