Here's what's new ↓
We cut nearly 2 MB of compressed JavaScript across 𝚟𝟶.𝚊𝚙𝚙 and 𝚟𝚎𝚛𝚌𝚎𝚕.𝚌𝚘𝚖 using coding agents and the Next.js Bundle Analyzer.
See how to trace imports, compare snapshots, and use our optimizer skill to reduce your bundles.
nextjs.org/blog/ship-less-ja…
Analyze your app’s bundles with the 𝚗𝚎𝚡𝚝-𝚋𝚞𝚗𝚍𝚕𝚎-𝚘𝚙𝚝𝚒𝚖𝚒𝚣𝚎𝚛 skill for Next.js 16.4:
▲ ~/ npx skills add vercel/next.js --skill next-bundle-optimizer
skills.sh/vercel/next.js/nex…
We used a coding agent with Next.js 16.4's new prefetching controls and Skill to improve v0's navigation experience at no added cost.
The loop:
• Capture navigation with 𝚒𝚗𝚜𝚝𝚊𝚗𝚝()
• Define the target UI in the test
• Refactor until it passes
nextjs.org/blog/improving-na…
The Partial Prefetching optimizer Skill turns a navigation goal into an 𝚒𝚗𝚜𝚝𝚊𝚗𝚝() test, then refactors the app until it passes.
Try it in your app:
npx skills add vercel/next.js --skill next-partial-prefetching-optimizer
skills.sh/vercel/next.js/nex…
The Next.js site has a new look!
We've redesigned the homepage, /docs, /blog, and more, with a consistent design that keeps the focus on the content.

A few highlights ↓
The Next.js Blog has a redesigned index for browsing posts and updated article layouts that make longer reads more comfortable.

An out-of-band Next.js security update is planned for Wednesday, October 14.
It will address three vulnerabilities in upstream dependencies, including two critical and one high-severity issue.
nextjs.org/blog/upcoming-nex…
We're also changing how we share future security notices ↓
We'll continue making Next.js more secure and publish notices on our security blog:
nextjs.org/blog/security
Routine updates won't be posted on social media unless there's something specific to call out. To follow future updates, subscribe via RSS:
nextjs.org/feed/security.xml
You can also follow security advisories through GitHub or a dependency monitoring service.
On the Next.js repository, choose Watch → Custom → Security alerts.

Next.js 16.4
• Cache Components by default in new apps
• Static output guarantees and more control over prefetching
• Agent-guided upgrades and feedback
• 20–25% smaller Turbopack disk cache
• Faster development and smaller bundles
nextjs.org/blog/next-16-4
Turbopack Bundle Analyzer now surfaces large client routes, snapshot diffs, and critical render-path modules.
Use the 𝚗𝚎𝚡𝚝-𝚋𝚞𝚗𝚍𝚕𝚎-𝚘𝚙𝚝𝚒𝚖𝚒𝚣𝚎𝚛 skill with your coding agent to reduce what reaches the browser.
skills.sh/vercel/next.js/nex…
Next.js 16.4 also includes React 19.3, with stable View Transitions and Fragment Refs, the new 𝚋𝚛𝚘𝚠𝚜𝚎𝚛() API, and Trusted Types support.
