The September 2026 security release is now available. Upgrade to 16.3.8 (Active LTS) or 15.5.27 (Maintenance LTS) now to address one High, five Medium, and one Low severity vulnerabilities.

Next.js is preparing a scheduled security release for September 30, 2026.

• The planned patched versions are Next.js 16.3.8 and 15.5.27.

The September 22, 2026 out-of-band security update is now available. Upgrade to 16.3.6 (Active LTS) or 15.5.26 (Maintenance LTS) now.

Next.js 16.3.6 and 15.5.26 are planned for a critical out-of-band security update on September 22, 2026.

The Next.js issue tracker had grown to 2,244 open reports, and inactivity was a poor way to decide what to close. We built an agent to research the backlog, maintainers reviewed its findings, and we closed 1,462 issues in less than a month.

Turbopack’s chunking speeds up page loads and enables sharing code across pages. We've shipped new experimental features to allow you to tune chunking for your website and to improve navigation performance on Next.js sites.

The August 2026 security release is now available. Upgrade to 16.3.3 (Active LTS) or 15.5.24 (Maintenance LTS) now to address two Critical severity vulnerabilities.

Next.js is moving the August security release forward to August 25, 2026.

• The release includes Next.js 16.3.3 and 15.5.24.
• It will address two critical severity vulnerabilities.

Next.js is preparing a scheduled security release for August 26, 2026.

• The release includes patches for Next.js 16.3 and 15.5.
• It will address one critical severity vulnerability.

With Instant Navigations in Next.js 16.3, you can build app-like experiences that respond immediately, preserve client state across navigations, and update optimistically, without giving up the benefits of Server Components.

Next.js 16.3 ships a new instant() test helper that verifies whether a navigation is instant. Using it through the next-cache-components-optimizer Skill, a coding agent wrote a failing test for each slow route in v0, applied fixes, and verified the routes, making navigations across the app instant.

Next.js 16.3 is now available. Highlights include:

• Improvements for today's apps: Up to 90% less memory in dev, plus faster builds and rendering.
• Instant Navigations: A suite of tools that brings single-page-app responsiveness to Next.js.

The first monthly security releases are now available. Upgrade to 16.2.11 (Active LTS) or 15.5.21 (Maintenance LTS) now to address 4 HIGH and 5 MEDIUM severity vulnerabilities.

Next.js is moving to a formal release process for security updates.

• We will publish security patches more regularly, and will give advance notice of these patches.
• The first new security release is expected on July 21, 2026, and will address multiple security issues.

We've spent the past year making Next.js work better with AI coding agents. From an experimental in-browser agent to MCP integration and improved logging, we learned that the key is treating agents as first-class users and giving them visibility into what Next.js is doing.

How we built Turbopack with incremental computation to scale development and builds to massive Next.js applications.

Next.js 16.1 is now available. Highlights include:

• Redesigned error UI and improved stack traces
• Streaming metadata
• Turbopack performance improvements

We’re working on a simple and powerful caching model for Next.js. In a previous post, we talked about our journey with caching and how we’ve arrived at the 'use cache' directive.

Next.js 15.1 introduces core upgrades, new APIs, and improvements to the developer experience including:

• React 19 (stable)
• Improved Error Debugging
• after (stable)
• forbidden / unauthorized (experimental)

Frontend performance can be hard to get right. Even in highly optimized apps, the most common culprit by far is client-server waterfalls. When introducing Next.js App Router, we knew we wanted to solve this issue. To do that, we needed to move client-server REST fetches to the server using React Server Components in a single roundtrip. This meant the server had to sometimes be dynamic, sacrificing the great initial loading performance of Jamstack. We built partial prerendering to solve this tradeoff and have the best of both worlds.

Our mission to create the best developer experience continues with Next.js 15, featuring:

• @next/codemod CLI
• Async Request APIs (Breaking)

Next.js has been designed for gradual adoption. With Next.js, you can continue using your existing code and add as much (or as little) React as you need. By starting small and incrementally adding more pages, you can prevent derailing feature work by avoiding a complete rewrite.

Many companies need to modernize their tech stack to reduce costs, increase developer productivity, and provide the best experience for their customers. Component-driven development has greatly improved the deployment velocity and reusability of modern codebases.

And with over 8 million downloads/month, React is the leading component-driven choice for developers. Next.js, the React framework for production, enables you to incrementally adopt React.
