Shadcn/UI switches to Base UI, major open-source change affecting many developers.
Summary
Shadcn/UI has switched its default component library from Radix to Base UI (v1.6.0, 6M+ weekly downloads), built by the same team. New projects via `npx shadcn init` now pick Base UI, while Radix remains fully supported and can be selected with the `-b radix` flag. Migration is optional and facilitated by an AI agent skill that progressively converts components with customizations, providing per-component reports and clean git history, rather than using a brittle codemod.
