v2.0.0-alpha.7

Breaking Changes

• The init lifecycle hook has been renamed to beforeCreated.

• JavaScript transition hooks now receive the context Vue instance as the second argument:

  Vue.transition('example', {
    onEnter (el, vm) {
      // ...
    }
  })

New

• $createElement can now omit the data argument if no data is needed. If the second argument is truthy and is not an Object, it will be treated as the children.

  render (h) {
    // before
    return h('div', null, 'hello')
    // after
    return h('div', 'hello')
  }

• SSR: Now supports bundle renderer, which runs a pre-bundled app script in a fresh context for each render. This eliminates the need for structuring your application without global state just for the sake of server-side rendering.

• SSR: Now supports component-level caching via server.getCacheKey option.

• Vue.config.errorHandler now also captures errors thrown in user watcher callbacks.
