It's been a while since last hearing anything about the GNOME/GTK Broadway back-end that provides HTML5-based user-interfaces for rendering within web browsers. The HTML5 Broadway work has been revived ahead of the GTK 4.0 tool-kit release.

The Broadway back-end has needed several adjustments to the rearchitecting that has gone on for the GTK4 tool-kit. These GTK4 changes have been to make modern GPU-based rendering more suitable in an OpenGL and Vulkan world but has made some Broadway changes more difficult and other areas easier. GTK4's Broadway back-end makes more use of the GTK native CSS, turns render nodes into actual DOM nodes, and even supporting 3D transforms via CSS.
