- Breaking: dynamic routes no longer require nuxt.config.js, router.routes removed, added validate() for route params/query and child‑route directories, rename .router-link-active to .nuxt-link-active.
- Feature: JavaScript hooks in transition (including function‑based transitions), new <nuxt-link> component, JSX support via upgraded webpack and vue‑loader.
- Improvements & bugfixes: import components without .vue extension, dev server no longer crashes on config syntax errors, upgraded to webpack 2.2.0, fixes for ES6 imports, Windows env handling, and renderer errors.
