Nuxt 4.6 made the server layer framework-agnostic with nuxt/server, rebuilt typed $fetch, and added sessions alongside a v4 CLI.
Nuxt 4.6 decoupled the server and refreshed $fetch. nuxt/server lets apps target non-Nitro servers, typed $fetch was rebuilt, and sessions, Vue Vapor support, and new dev error pages arrive together.
Nuxt CLI v4 turns nuxt dev into a dashboard.
- Interactive terminal UI showing URLs, startup progress, and keyboard shortcuts
- Panels for error logs, routes, and network requests
- Startup and build timing breakdowns, including per-module setup cost, plus why the dev server reloaded or restarted
- A
.nuxt/ lock file so a second nuxt dev — one started by an agent, say — takes over or defers to yours
Nuxt 4.5 rebuilt the build layer. Vite 8 and Rspack 2 land, the Rspack builder gets a new Rsbuild-powered pipeline, and experimental SSR streaming arrives alongside stable error codes, a useLayout composable, and named views. Opt in early to Nuxt 5 breaking changes with future.compatibilityVersion: 5.
Security release: upgrade now. v4.5.1 and v3.21.10 close server-side RCE and unauthorized component instantiation via server island props, a route-rule authorization bypass, server component DoS, and cross-user payload disclosure on cached pages. Refresh your lockfile for the critical dev-only RCE fixed in @nuxt/devtools 3.3.1, and purge CDN or edge caches if you use cache, swr, or isr route rules — a leaked _payload.json may already be cached upstream. Nuxt v3 reached end-of-life with v3.21.11; upgrade to v4.
