We contributed a change to React that makes Server Components payload deserialization up to ~350% faster. In real Next.js apps, that's 25–60% faster rendering to HTML.

Server Function calls are now logged in the terminal during 𝚗𝚎𝚡𝚝 𝚍𝚎𝚟. You'll see the function name, arguments, execution time, and source file.

The default production error page has been redesigned. If you haven't defined a custom 𝚎𝚛𝚛𝚘𝚛.𝚝𝚜𝚡 or 𝚐𝚕𝚘𝚋𝚊𝚕-𝚎𝚛𝚛𝚘𝚛.𝚝𝚜𝚡, the built-in fallback now has a cleaner, more modern look.

Hydration mismatch errors now show a + 𝙲𝚕𝚒𝚎𝚗𝚝 / - 𝚂𝚎𝚛𝚟𝚎𝚛 label, so you can clearly spot each environment.
