+## 15.4.0 (November 16, 2016)
+
+### React
+* React package and browser build no longer "secretly" includes React DOM. ([@sebmarkbage](https://github.com/sebmarkbage) in [#7164](https://github.com/facebook/react/pull/7164) and [#7168](https://github.com/facebook/react/pull/7168))
+* Required PropTypes now fail with specific messages for null and undefined. ([@chenglou](https://github.com/chenglou) in [#7291](https://github.com/facebook/react/pull/7291))
+* Improved development performance by freezing children instead of copying. ([@keyanzhang](https://github.com/keyanzhang) in [#7455](https://github.com/facebook/react/pull/7455))
+
+### React DOM
+* Fixed occasional test failures when React DOM is used together with shallow renderer. ([@goatslacker](https://github.com/goatslacker) in [#8097](https://github.com/facebook/react/pull/8097))
+* Added a warning for invalid `aria-` attributes. ([@jessebeach](https://github.com/jessebeach) in [#7744](https://github.com/facebook/react/pull/7744))
+* Added a warning for using `autofocus` rather than `autoFocus`. ([@hkal](https://github.com/hkal) in [#7694](https://github.com/facebook/react/pull/7694))
+* Removed an unnecessary warning about polyfilling `String.prototype.split`. ([@nhunzaker](https://github.com/nhunzaker) in [#7629](https://github.com/facebook/react/pull/7629))
+* Clarified the warning about not calling PropTypes manually. ([@jedwards1211](https://github.com/jedwards1211) in [#7777](https://github.com/facebook/react/pull/7777))
+* The unstable `batchedUpdates` API now passes the wrapped function's return value through. ([@bgnorlov](https://github.com/bgnorlov) in [#7444](https://github.com/facebook/react/pull/7444))
+* Fixed a bug with updating text in IE 8. ([@mnpenner](https://github.com/mnpenner) in [#7832](https://github.com/facebook/react/pull/7832))
+
+### React Perf
+* When ReactPerf is started, you can now view the relative time spent in components as a chart in Chrome Timeline. ([@gaearon](https://github.com/gaearon) in [#7549](https://github.com/facebook/react/pull/7549))
+
+### React Test Utils
+* If you call `Simulate.click()` on a `<input disabled onClick={foo} />` then `foo` will get called whereas it didn't before. ([@nhunzaker](https://github.com/nhunzaker) in [#7642](https://github.com/facebook/react/pull/7642))
+
+### React Test Renderer
+* Due to packaging changes, it no longer crashes when imported together with React DOM in the same file. ([@sebmarkbage](https://github.com/sebmarkbage) in [#7164](https://github.com/facebook/react/pull/7164) and [#7168](https://github.com/facebook/react/pull/7168))
+* `ReactTestRenderer.create()` now accepts `{createNodeMock: element => mock}` as an optional argument so you can mock refs with snapshot testing. ([@Aweary](https://github.com/Aweary) in [#7649](https://github.com/facebook/react/pull/7649), [#8261](https://github.com/facebook/react/pull/8261))
