Nuxt has released version 4.5, featuring updates such as a switch to Vite 8, a new Rspack 2 builder, and experimental SSR streaming. This streaming enhances Time to First Byte by flushing the HTML shell instantly. The release also includes a stable error code system and new composables, alongside important upgrade instructions for developers moving from earlier versions. By Daniel Curtis
