Summary

Base UI, an unstyled React component library developed by the creators of Radix, Floating UI, and Material UI, has released version 1, signifying its production-ready stability after two years. This release includes 35 accessible components, a package rename from `@base-ui-components/react` to `@base-ui/react`, and a commitment to long-term maintenance by a dedicated team at MUI. Version 1.x refines the developer experience with improved component APIs, enhanced accessibility, and better integration with styling solutions like Tailwind CSS and CSS Modules. Its headless architecture offers full styling control while ensuring WCAG compliance through robust accessibility features, distinguishing it from competitors like Radix UI due to MUI's corporate backing and long-term support. The release also brings component-specific improvements, such as enhanced form handling for Combobox and Select, and fixes for Menu component behaviors.
