Kind: tutorial · Impact: medium

## In brief

- Nuxt 3 reached end of life on 31 July 2026 and no longer receives security patches or bug fixes.
- New Nuxt module releases are moving to Nuxt 4.
- The article covers seven Nuxt 4 changes that break apps and how to find them, and says the Nuxt 3 to 4 upgrade is smaller than the Nuxt 2 to 3 upgrade was.

## Why it matters

Nuxt 3 apps still run but stop getting security fixes, and new modules will target Nuxt 4, so upgrading becomes a practical necessity.

## What to do

- Check your app for the seven Nuxt 4 breaking changes covered in the article and upgrade to Nuxt 4.

## Versions

- Nuxt 3
- Nuxt 4
