Changelog
New components, blocks, and docs improvements.
September 2026
Docs
- Every component and block page now has installation with CLI and manual tabs, usage, an API reference, keyboard, accessibility, and motion notes.
- Search the library with / or ⌘ K, filter the sidebar by Free or Pro, and read the new Installation, Theming, and Motion guides.
- Close block variants share one page with a variant switcher: sidebars, login, onboarding, team, settings, pricing, checkout, analytics, AI chat, inbox and support, scheduling, project views, and feature sections. Old links still work.
Registry and AI
- Install by name with the
@uiarcregistry namespace. - An MCP server,
llms.txt, and a Markdown version of every page. See AI and MCP.
