An out-of-band Next.js security update is planned for September 22, 2026.
It addresses a critical issue in an upstream dependency. Upgrade to Next.js 16.3.6 or 15.5.26 as soon as they are available.

We closed 1,500 issues on 𝚟𝚎𝚛𝚌𝚎𝚕/𝚗𝚎𝚡𝚝.𝚓𝚜 in one month by building a 𝚌𝚕𝚘𝚜𝚊𝚋𝚒𝚕𝚒𝚝𝚢 agent with @eve.
The workflow:
1. Search related work
2. Try to reproduce bugs across versions in a sandbox
3. Return context for review

Your Next.js app ships dozens of JavaScript chunks. Turbopack has to balance how many requests a page makes against how much code it ships.
Learn how it works and what's new in Next.js 16.3.

The August Next.js security release is now available one day ahead of schedule to include a fix for a newly disclosed vulnerability in an upstream dependency.

We’ve moved the scheduled August Next.js security release forward to today, August 25, to include a fix for an additional critical severity vulnerability.
nextjs.org/blog/nextjs-se…
Next.js 16.3.3 and 15.5.24 will include fixes for both vulnerabilities. Upgrade once they are available.
In July, we began announcing Next.js security releases ahead of time. The next security release is planned for August 26, 2026.
It will address one critical severity vulnerability with fixes in 16.3.2 and 15.5.24, so upgrade once they are available.

We're the Next.js team. Ask us anything!
We recently shipped Next.js 16.3, and we’re excited to talk about what’s new, how we approached the release, where we are going, and what we’ve learned while building and maintaining Next.
Ask us anything about Next 16.3, App Router, React Server Components, performance, caching, upgrading your applications, contributing to the framework, or what it’s like to work on Next.js.
Instant Navigations in Next.js 16.3 lets you achieve snappy, app-like UX without giving up the benefits of Server Components.
See how Cache Components and Partial Prefetching come together in a music player, social feed, calendar, and team chat.

You can run the loop on your own app.
Grab the Skill and prompt your agent with something like:
"Make the navigation from /dashboard to /projects instant using the next-cache-components-optimizer Skill."

Navigations in v0 got ~3.5× faster with Next.js 16.3.
An agent ran this loop on each slow nav:
1. Write a failing 𝚒𝚗𝚜𝚝𝚊𝚗𝚝() test
2. Apply a fix from the Skill
3. Re-run the test
4. Repeat 2–3 until it passes

When the network drops, requests normally throw. The experimental 𝚎𝚡𝚙𝚎𝚛𝚒𝚖𝚎𝚗𝚝𝚊𝚕.𝚞𝚜𝚎𝙾𝚏𝚏𝚕𝚒𝚗𝚎 flag keeps them pending and retries on reconnect.
A companion 𝚞𝚜𝚎𝙾𝚏𝚏𝚕𝚒𝚗𝚎 hook reports when you're offline, so you can render some UI to let your users know.
The React Compiler optimizes your components at build time, letting you skip manual memoization.
The React team built a Rust port of it, which we run in Turbopack instead of Babel. We tried this experimental version on v0: 34% faster to a ready page cold, 46% warm.
Next.js 16.3 is now available!
• Up to 90% less memory in dev
• Faster builds, type checking, and rendering
• Better tooling for AI agents
• Custom error boundaries
• Instant Navigations for SPA-like responsiveness
