Next.js 16.2

This release is packed with performance improvements, better debugging tools, and AI-focused features:

• ~400% faster dev startup – localhost:3000 is ready much quicker during next dev
• 25-60% faster rendering – a smarter JSON parsing approach speeds up Server Components payload deserialization
• Redesigned 500 error page – cleaner built-in fallback page for production errors
• Server Function logging – dev terminal now shows function name, arguments, and execution time
• Hydration diff indicator – error overlay clearly labels server vs. client content mismatches
• --inspect for next start – attach a Node.js debugger to your production server
• 200+ Turbopack fixes – including SRI support, postcss.config.ts, and Server Fast Refresh
• AI improvements – AGENTS.md in create-next-app, browser log forwarding, and experimental next-browser

unstable_catchError()

The Next.js team is working on a programmatic way to wrap any part of your UI in an error boundary. It's more flexible than the error.js convention, supporting custom props, retry logic, and server-rendered fallbacks

📦 Projects / Packages / Tools

next-forge 6

next-forge is a production-ready template for Next.js that aims to be a full, opinionated starter for new apps. This big release adds better DX, a new "agent skill" you can install for structured next-forge knowledge, and new docs. Bun is now the default package manager (pnpm/npm/yarn still work)

AI Elements 1.9

The latest update adds a new skill to help agents build with the library, plus a <JSXPreview /> component for rendering streamed JSX and a screenshot action for <PromptInput />. The <Conversation /> component can also now download chats as markdown

Base UI v1.3.0

Version 1.3.0 brings lots of small fixes plus a few big wins: Drawer is now stable, plus a new SwipeArea for Drawer. Select, Combobox, and Slider get a new Label part, and Combobox + Autocomplete add an InputGroup part. Tooltip adds a closeOnClick prop, and Menu now supports content transitions via Viewport

Streamdown 2.5

Streamdown is a component designed to render Markdown streamed from AI models. In version 2.5 new staggered animations cascade content in sequentially, custom renderers can now read code fence metastrings, and line numbers are toggleable. There are also other performance related improvements
