	tl;dr: Shadcn/UI has made Base UI the default component library for new projects, replacing Radix, since Base UI (built by the original Radix team) has matured to 1.6.0 with 6M+ weekly downloads and users were already choosing it 2-to-1 in shadcn/create. Radix isn't deprecated—it remains fully supported with a one-flag opt-in—and existing projects don't need to migrate, though an AI agent "skill" is provided for progressive, component-by-component migration. The release also coincides with new chat interface components, GitHub-based registries, a `shadcn eject` command, and a new compact style called Rhea.
