# [3.0.0-alpha.4](https://github.com/vuejs/vue-next/compare/v3.0.0-alpha.3...v3.0.0-alpha.4) (2020-01-27)


### Bug Fixes

* adjust `createApp` related API signatures ([c07751f](https://github.com/vuejs/vue-next/commit/c07751fd3605f301dc0f02fd2a48acc7ba7a0397))
* remove implicit reactive() call on renderContext ([6b10f0c](https://github.com/vuejs/vue-next/commit/6b10f0cd1da942c1d96746672b5f595df7d125b5))


### Performance Improvements

* **ssr:** avoid unnecessary async overhead ([297282a](https://github.com/vuejs/vue-next/commit/297282a81259289bfed207d0c9393337aea70117))


### BREAKING CHANGES

* object returned from `setup()` are no longer implicitly
passed to `reactive()`.

  The renderContext is the object returned by `setup()` (or a new object
  if no setup() is present). Before this change, it was implicitly passed
  to `reactive()` for ref unwrapping. But this has the side effect of
  unnecessary deep reactive conversion on properties that should not be
  made reactive (e.g. computed return values and injected non-reactive
  objects), and can lead to performance issues.

  This change removes the `reactive()` call and instead performs a
  shallow ref unwrapping at the render proxy level. The breaking part is
  when the user returns an object with a plain property from `setup()`,
  e.g. `return { count: 0 }`, this property will no longer trigger
  updates when mutated by a in-template event handler. Instead, explicit
  refs are required.

  This also means that any objects not explicitly made reactive in
  `setup()` will remain non-reactive. This can be desirable when
  exposing heavy external stateful objects on `this`.
* `createApp` API has been adjusted.

  - `createApp()` now accepts the root component, and optionally a props
  object to pass to the root component.
  - `app.mount()` now accepts a single argument (the root container)
  - `app.unmount()` no longer requires arguments.

  New behavior looks like the following:

  ``` js
  const app = createApp(RootComponent)
  app.mount('#app')
  app.unmount()
  ```
