### [`v16.8.0`](https://togithub.com/facebook/react/blob/master/CHANGELOG.md#1680-February-6-2019)
[Compare Source](https://togithub.com/facebook/react/compare/v16.7.0...v16.8.0)
##### React
- Add [Hooks](https://reactjs.org/docs/hooks-intro.html) — a way to use state and other React features without writing a class. ([@acdlite](https://togithub.com/acdlite) et al. in [#13968](https://togithub.com/facebook/react/pull/13968))
- Improve the `useReducer` Hook lazy initialization API. ([@acdlite](https://togithub.com/acdlite) in [#14723](https://togithub.com/facebook/react/pull/14723))
##### React DOM
- Bail out of rendering on identical values for `useState` and `useReducer` Hooks. ([@acdlite](https://togithub.com/acdlite) in [#14569](https://togithub.com/facebook/react/pull/14569))
- Use `Object.is` algorithm for comparing `useState` and `useReducer` values. ([@Jessidhia](https://togithub.com/Jessidhia) in [#14752](https://togithub.com/facebook/react/pull/14752))

- Render components with Hooks twice in Strict Mode (DEV-only) to match class behavior. ([@gaearon](https://togithub.com/gaearon) in [#14654](https://togithub.com/facebook/react/pull/14654))
- Warn about mismatching Hook order in development. ([@threepointone](https://togithub.com/threepointone) in [#14585](https://togithub.com/facebook/react/pull/14585) and [@acdlite](https://togithub.com/acdlite) in [#14591](https://togithub.com/facebook/react/pull/14591))
- Effect clean-up functions must return either `undefined` or a function. All other values, including `null`, are not allowed. [@acdlite](https://togithub.com/acdlite) in [#14119](https://togithub.com/facebook/react/pull/14119)
##### React Test Renderer and Test Utils
- Support Hooks in the shallow renderer. ([@trueadm](https://togithub.com/trueadm) in [#14567](https://togithub.com/facebook/react/pull/14567))
- Fix wrong state in `shouldComponentUpdate` in the presence of `getDerivedStateFromProps` for Shallow Renderer. ([@chenesan](https://togithub.com/chenesan) in [#14613](https://togithub.com/facebook/react/pull/14613))
- Add `ReactTestRenderer.act()` and `ReactTestUtils.act()` for batching updates so that tests more closely match real behavior. ([@threepointone](https://togithub.com/threepointone) in [#14744](https://togithub.com/facebook/react/pull/14744))
##### ESLint Plugin: React Hooks
- Initial [release](https://www.npmjs.com/package/eslint-plugin-react-hooks). ([@calebmer](https://togithub.com/calebmer) in [#13968](https://togithub.com/facebook/react/pull/13968))

- Don't consider throwing to be a rule violation. ([@sophiebits](https://togithub.com/sophiebits) in [#14040](https://togithub.com/facebook/react/pull/14040))
### [`v16.7.0`](https://togithub.com/facebook/react/blob/master/CHANGELOG.md#1670-December-19-2018)
##### React DOM
- Fix performance of `React.lazy` for large numbers of lazily-loaded components. ([@acdlite](http://github.com/acdlite) in [#14429](https://togithub.com/facebook/react/pull/14429))

- Fix a performance regression in profiling mode. ([@bvaughn](http://github.com/bvaughn) in [#14383](https://togithub.com/facebook/react/pull/14383))
##### Scheduler (Experimental)
- Post to MessageChannel instead of window. ([@acdlite](http://github.com/acdlite) in [#14234](https://togithub.com/facebook/react/pull/14234))
