Storybook 10.4 ships several notable features: AI agents can now automatically configure Storybook in complex apps by analyzing project structure, generating mocks, and writing stories; a new sidebar change detection filter highlights stories affected by recent code changes; a quick-share button publishes Storybook to Chromatic for instant teammate review without needing a PR or CI run. The release also adds first-class TanStack React framework support via @storybook/tanstack-react with zero-config routing and server functions, an improved opinionated React Native setup using a standalone entry point, and an experimental react-component-meta docgen analyzer powered by Volar and the TypeScript Language Server for faster, higher-quality MCP metadata.
