+## 0.8.4 (December 11, 2016)
+
+#### :bug: Bug Fix
+* `react-scripts`
+
+  * [#1233](https://github.com/facebookincubator/create-react-app/pull/1233) Disable subresource integrity temporarily. ([@Timer](https://github.com/Timer))
+
+    We added [Subresource Integrity](https://developer.mozilla.org/en-US/docs/Web/Security/Subresource_Integrity) checks to the build output in 0.8.2 but it turns out that they may fail in browsers using special compression proxies, such as Chrome on Android, when served over HTTP. We disabled the checks until we can find a safe way to add them.
+
+* `react-dev-utils`
+
+  * [#1226](https://github.com/facebookincubator/create-react-app/pull/1226) Fix weird lint output. ([@n3tr](https://github.com/n3tr))
+
+    Fixes a strange lint message formatting in some edge cases.
+
+  * [#1215](https://github.com/facebookincubator/create-react-app/pull/1215) Fix - openChrome won't open default browser (using Canary). ([@n3tr](https://github.com/n3tr))
+
+    Fixes an regression that caused stable Google Chrome to be opened even if you are using Canary as the default browser.
+
+* `create-react-app`
+
+  * [#1223](https://github.com/facebookincubator/create-react-app/pull/1223) Clean up Yarn detection and install code. ([@fson](https://github.com/fson))
+
+  Fixes noisy output on Windows when Yarn is not installed.
+
+  * [#1224](https://github.com/facebookincubator/create-react-app/pull/1224) Exit with an error code when npm/yarn install fails. ([@fson](https://github.com/fson))
+
+#### :nail_care: Enhancement

+
+  * [#1237](https://github.com/facebookincubator/create-react-app/pull/1237) Clear scrollback in test mode. ([@gaearon](https://github.com/gaearon))

+
+    Since coverage doesn't work well with watch mode, we don’t run the watcher on `npm test -- --coverage` anymore.
+
+  * [#1212](https://github.com/facebookincubator/create-react-app/pull/1212) Proxy rewrites Origin header to match the target server URL. ([@koles](https://github.com/koles))

+* `create-react-app`
+
+  * [#1236](https://github.com/facebookincubator/create-react-app/pull/1236) Tweak console messages. ([@gaearon](https://github.com/gaearon))
