## 0.8.0 (2016-12-03)
#### :rocket: New Feature
* `react-scripts`
* [#944](https://github.com/facebookincubator/create-react-app/pull/944) Crash the build during CI whenever linter warnings are encountered. ([@excitement-engineer](https://github.com/excitement-engineer))
Linter warnings and errors are now checked during a continuous integration build (set by the `CI` environment variable) and the build will fail if any issues are found. See [Continuous Integration](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#continuous-integration) for more information.
* [#1090](https://github.com/facebookincubator/create-react-app/pull/1090) Enable proxying of WebSockets. ([@dceddia](https://github.com/dceddia))
* `create-react-app`, `react-scripts`
* [#898](https://github.com/facebookincubator/create-react-app/pull/898) Support Yarn. ([@fson](https://github.com/fson))
Yarn is a new fast, reliable and secure alternative to the `npm` client. If you have Yarn installed, `create-react-app` will use it to install packages when you create an app. It also creates a `yarn.lock` file that should be checked into source control (e.g. git). This ensures the same versions of packages will be installed each time `yarn install` is run, on any machine.
`react-scripts` now also displays instructions using `yarn` commands for projects using Yarn (projects having a `yarn.lock` file).
To create a project using Yarn, simply install `yarn` and use `create-react-app` like before:
```
npm install -g yarn create-react-app@latest
create-react-app my-app # Packages are now installed with Yarn.
```
#### :boom: Breaking Change
* `babel-preset-react-app`
* [#902](https://github.com/facebookincubator/create-react-app/pull/902) Enable useBuiltIns option on object-rest-spread. ([@existentialism](https://github.com/existentialism))
Object rest spread and JSX now use the native `Object.assign()` method instead of Babel's helper function. If you are using `babel-preset-react-app` directly in your project *and* targeting browsers that don't have `Object.assign()` available, from now on you need a polyfill for it (e.g. [`object-assign`](https://www.npmjs.com/package/object-assign)).
**Note:** `react-scripts` already adds this polyfill, so no changes are necessary in Create React App projects.
#### :bug: Bug Fix
* `react-scripts`
* [#978](https://github.com/facebookincubator/create-react-app/pull/978) Move the remove-on-eject-end tag at the end of the file. ([@EnoahNetzach](https://github.com/EnoahNetzach))
Fixes a bug in ejected configuration.
* [#1017](https://github.com/facebookincubator/create-react-app/pull/1017) Don't look for `.babelrc` file during test. ([@nhajidin](https://github.com/nhajidin))
Fixes a `.babelrc` file in a parent directory interfering with the `npm test` command.
* [#951](https://github.com/facebookincubator/create-react-app/pull/951) Check for presence of folders before continuing eject. ([@heldinz](https://github.com/heldinz))
Fixes a bug where `eject` failed when a `scripts` or `config` folder already existed in the project.
* `react-dev-utils`
* [#1035](https://github.com/facebookincubator/create-react-app/pull/1035) Fix Chrome tab reuse. ([@einarlove](https://github.com/einarlove))
Fixes a bug with the app not opening in the existing tab in Chrome.
* [#964](https://github.com/facebookincubator/create-react-app/pull/964) Catch and noop call to open web browser. ([@spadin](https://github.com/spadin))
Not being able to open a browser doesn't crash the development server now.
* `eslint-config-react-app`, `react-scripts`
* [#953](https://github.com/facebookincubator/create-react-app/pull/953) Fix `.ico` file extension being handled by test configuration. ([@vadzim](https://github.com/vadzim))
#### :nail_care: Enhancement
* `react-scripts`
* [#1032](https://github.com/facebookincubator/create-react-app/pull/1032) Add support for non-interactive terminal. ([@sheerun](https://github.com/sheerun))
* [#1078](https://github.com/facebookincubator/create-react-app/pull/1078) Upgrade Jest to 17.0. ([@fson](https://github.com/fson))
* [#1059](https://github.com/facebookincubator/create-react-app/pull/1059) Use `url-loader` with limit 10k as a default loader. ([@bebbi](https://github.com/bebbi))
`react-scripts` now treats imports with any unknown file extension as a resource. Files with a size below 10 KB are inlined using a data URI and larger files copied to the build folder. This removes the need for an internal [whitelist of supported file extensions](https://github.com/facebookincubator/create-react-app/issues/667). Any file that's not JS or CSS is now handled the same way.
* [#924](https://github.com/facebookincubator/create-react-app/pull/924) Enable JavaScript source maps in development. ([@ekaradon](https://github.com/ekaradon))
* [#1058](https://github.com/facebookincubator/create-react-app/pull/1058) Add missing dev argument in build script message. ([@nhajidin](https://github.com/nhajidin))
* [#961](https://github.com/facebookincubator/create-react-app/pull/961) Add `collectCoverageFrom` option to collect coverage on files without any tests. ([@pmackcode](https://github.com/pmackcode))
The test script now considers all files in the project when calculating test coverage.
* [#968](https://github.com/facebookincubator/create-react-app/pull/968) Enable gzip compression in the development server (#966). ([@frontsideair](https://github.com/frontsideair))
* `react-dev-utils`, `react-scripts`
* [#816](https://github.com/facebookincubator/create-react-app/pull/816) add logging of existing default port process on start. ([@ianmcnally](https://github.com/ianmcnally))
`react-scripts` can guess which process is running on the port 3000 when it's not available:
```
Something is already running on port 3000. Probably:
my-app
in /Users/ian/dev/my-app
Would you like to run the app on another port instead?
```
* `react-dev-utils`
* [#963](https://github.com/facebookincubator/create-react-app/pull/963) Allow webpack 2 as a peerDependency in react-dev-utils. ([@einarlove](https://github.com/einarlove))
#### :memo: Documentation
* `react-scripts`
* [#1126](https://github.com/facebookincubator/create-react-app/pull/1126) Add a note about vscode-jest. ([@orta](https://github.com/orta))
* [#1080](https://github.com/facebookincubator/create-react-app/pull/1080) Add a note for OSX users about watchman and jest. ([@dmr](https://github.com/dmr))
* [#1071](https://github.com/facebookincubator/create-react-app/pull/1071) Adds to docs - deployment with S3/CloudFront. ([@marcgarreau](https://github.com/marcgarreau))
* [#976](https://github.com/facebookincubator/create-react-app/pull/976) Added info on using global variables. ([@jhorneman](https://github.com/jhorneman))
* [#996](https://github.com/facebookincubator/create-react-app/pull/996) Remove redundant `function` from export statement. ([@gnowoel](https://github.com/gnowoel))

* [#974](https://github.com/facebookincubator/create-react-app/pull/974) Gently nudge users towards https by default. ([@Swizec](https://github.com/Swizec))
* Other
* [#1031](https://github.com/facebookincubator/create-react-app/pull/1031) No Configuration -> Convention over Configuration. ([@sheerun](https://github.com/sheerun))
* [#995](https://github.com/facebookincubator/create-react-app/pull/995) Add Gatsby to alternatives. ([@KyleAMathews](https://github.com/KyleAMathews))

### Migrating from 0.6.1 to 0.7.0
You may optionally update the global command (it’s not required):
```
npm install -g create-react-app@0.6.0
```
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.7.0
```
### Breaking Change in 0.7.0
#### Updating Snapshots
Jest 16 includes [improvements to snapshot testing and changes to the snapshot format](https://facebook.github.io/jest/blog/2016/10/03/jest-16.html#snapshot-updates). If your project uses snapshot testing, you'll need to update the snapshot files. To update the snapshots, run:
```
npm test -- -u
```
## 0.6.1 (September 27, 2016)
### Build Dependency (`react-scripts`)
* Babel and ESLint configuration is now placed into `package.json` after ejecting. ([@montogeek](https://github.com/montogeek) in [#773](https://github.com/facebookincubator/create-react-app/pull/773))
### Utilities (`react-dev-utils`)
* Fixes the syntax error overlay padding. ([@fson](https://github.com/fson) in [#758](https://github.com/facebookincubator/create-react-app/pull/758))
### Migrating from 0.6.0 to 0.6.1

### Migrating from 0.5.1 to 0.6.0
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.6.0
```
**Note: If the project fails to start, remove `node_modules`, ensure `react-scripts` is `0.6.0` in your `package.json`, and run `npm install` again. There seems to be an [npm bug](https://github.com/npm/npm/issues/14073) affecting this update.**
## 0.5.1 (September 23, 2016)
### Build Dependency (`react-scripts`)
* Updates `react-dev-utils` dependency
### Utilities (`react-dev-utils`)
* Fixes `%PUBLIC_URL%` replacement to work when specified multiple times. ([@fson](https://github.com/fson) in [#731](https://github.com/facebookincubator/create-react-app/pull/731))
### Migrating from 0.5.0 to 0.5.1
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.5.1
```
## 0.5.0 (September 23, 2016)
### Build Dependency (`react-scripts`)

* You can now [specify defaults](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#adding-development-environment-variables-in-env) for environment variables with `.env` file. ([@ayrton](https://github.com/ayrton) in [#695](https://github.com/facebookincubator/create-react-app/pull/695))
* Ejecting now generates proper `.babelrc` and `.eslintrc`. ([@fson](https://github.com/fson) in [#689](https://github.com/facebookincubator/create-react-app/pull/689), [@gaearon](https://github.com/gaearon) in [#705](https://github.com/facebookincubator/create-react-app/pull/705))
* Some React warnings now [include the component stacktrace](https://twitter.com/dan_abramov/status/779308833399332864). ([@gaearon](https://github.com/gaearon) in [#716](https://github.com/facebookincubator/create-react-app/pull/716))
* `npm start` doesn’t fail in a composed Docker container. ([@arekkas](https://github.com/arekkas) in [#711](https://github.com/facebookincubator/create-react-app/issues/711))
* The projects generated with `eject` are now cleaner. ([@gaearon](https://github.com/gaearon) in [#723](https://github.com/facebookincubator/create-react-app/pull/723))
* The project is now managed as a monorepo. ([@ryanyogan](https://github.com/ryanyogan) in [#419](https://github.com/facebookincubator/create-react-app/pull/419), [@fson](https://github.com/fson) in [#678](https://github.com/facebookincubator/create-react-app/pull/678))
### ESLint Config (`eslint-config-react-app`)
* Published for the first time! ([@fson](https://github.com/fson) in [#689](https://github.com/facebookincubator/create-react-app/pull/689))
* Added [`react/no-danger-with-children`](https://github.com/yannickcr/eslint-plugin-react/blob/v6.3.0/docs/rules/no-danger-with-children.md) and [`react/style-prop-object`](https://github.com/yannickcr/eslint-plugin-react/blob/v6.3.0/docs/rules/style-prop-object.md) rules. ([@fson](https://github.com/fson) in [#696](https://github.com/facebookincubator/create-react-app/pull/696))
### Babel Preset (`babel-preset-react-app`)
* Published for the first time! ([@fson](https://github.com/fson) in [#701](https://github.com/facebookincubator/create-react-app/pull/701))
### Utilities (`react-dev-utils`)
* Published for the first time! ([@gaearon](https://github.com/gaearon) in [#723](https://github.com/facebookincubator/create-react-app/pull/723))
### Global CLI (`create-react-app`)
* Added `README` to npm. There were no other changes.
### Migrating from 0.4.3 to 0.5.0
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.5.0
```
### Breaking Changes in 0.5.0
#### Global ESLint Plugin Versions
If you used a global ESLint installation for the editor integration, you’ll need to install [these versions of global ESLint packages](https://github.com/facebookincubator/create-react-app/blob/c092086b1b256fd081f10744f90d216dd5217e29/packages/eslint-config-react-app/package.json#L14-L19).
#### Moving `index.html` into `public` Folder
You’ll also need to create a new folder called `public` in the root of your project. Then, move `index.html` and files it references (such as a favicon) into that folder.
You can no longer reference any files from `./src` in `index.html`. Instead, `public/index.html` can now only reference files other inside of the `public` folder using a special variable called `%PUBLIC_URL%`.
For example, instead of:
```js
<link rel="shortcut icon" href="./src/favicon.ico">
```
You would need to move both `index.html` and `src/favicon.ico` into the `public` folder, and change `<link>` to look like this:
```html
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">
```
This ensures it become a part of the build output, and resolves correctly both with client-side routing and non-root `homepage` in `package.json`. Read more about [using the `public` folder](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#using-the-public-folder) and [why these changes were made](https://github.com/facebookincubator/create-react-app/pull/703).

### Migrating from 0.4.2 to 0.4.3
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.4.3
```
## 0.4.2 (September 18, 2016)
### Build Dependency (`react-scripts`)
* Lint output in editor is now opt-in because, due to [this ESLint issue](https://github.com/eslint/eslint/issues/3458), it is broken by default in Atom. ([@fson](https://github.com/fson) in [#649](https://github.com/facebookincubator/create-react-app/pull/649))
* Fixes an issue causing compile errors when project folder is inside a symlink. ([@motiz88](https://github.com/motiz88) in [#648](https://github.com/facebookincubator/create-react-app/pull/648))
* You can now import `jpeg`, `wav`, `mp3`, `m4a`, `aac`, and `oga`. ([@mareksuscak](https://github.com/mareksuscak) in [#624](https://github.com/facebookincubator/create-react-app/pull/624), [@danharper](https://github.com/danharper) in [#665](https://github.com/facebookincubator/create-react-app/pull/665))

### Global CLI (`create-react-app`)
* It now runs on early Node versions to print a friendly warning instead of crashing. ([@sotojuan](https://github.com/sotojuan) in [fc3ab4](https://github.com/facebookincubator/create-react-app/commit/fc3ab46d2a54f142f9287ce7de9ab2fc2514487d))
* We now print a friendly message when you create a project with invalid name. ([@mareksuscak](https://github.com/mareksuscak) in [#628](https://github.com/facebookincubator/create-react-app/pull/628))

### Migrating from 0.4.1 to 0.4.2
You may optionally update the global command (it’s not required):
```
npm install -g create-react-app@0.4.2
```
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.4.2
```
## 0.4.1 (September 3, 2016)
### Build Dependency (`react-scripts`)
* We now support (but [don’t recommend](https://github.com/facebookincubator/create-react-app/issues/87#issuecomment-234627904)) `.jsx` file extension. ([@tizmagik](https://github.com/tizmagik) in [#563](https://github.com/facebookincubator/create-react-app/pull/563))
* Proxy request errors are now printed to the console. ([@cloudmu](https://github.com/cloudmu) in [#502](https://github.com/facebookincubator/create-react-app/pull/502))
### Migrating from 0.4.0 to 0.4.1
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.4.1
```
## 0.4.0 (September 2, 2016)
### Build Dependency (`react-scripts`)
* **Breaking Change:** Disabled implicit serving of source files in development. ([@gaearon](https://github.com/gaearon) in [#551](https://github.com/facebookincubator/create-react-app/pull/551))
* You can use `NODE_PATH` environment variable for absolute `import` paths. ([@jimmyhmiller](https://github.com/jimmyhmiller) in [#476](https://github.com/facebookincubator/create-react-app/pull/476))
* If `src/setupTests.js` exists, it will be used to setup the test environment. ([@gaelduplessix](https://github.com/gaelduplessix) in [#548](https://github.com/facebookincubator/create-react-app/pull/548))
* If `HTTPS` environment variable is set to `true`, development server will run in HTTPS mode. ([@dceddia](https://github.com/dceddia) in [#552](https://github.com/facebookincubator/create-react-app/pull/552))
### Migrating from 0.3.1 to 0.4.0
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.4.0
```
### Breaking Change in 0.4.0
Paths like `/src/somefile.png` used to be served in development, but only by accident. They never worked in production builds. Since 0.4.0, we [don’t serve static files by default in development anymore either](https://github.com/facebookincubator/create-react-app/pull/551). This removes a dangerous inconsistency that we never intentionally supported.
If you need a static file to be part for the build, [import it from JavaScript and you will get its filename](https://github.com/facebookincubator/create-react-app/blob/master/template/README.md#adding-images-and-fonts). This ensures it gets included into the production build as well, and its filename contains the content hash.
If you used static files with `<link href>`, [read this new guide](https://github.com/facebookincubator/create-react-app/blob/master/template/README.md#referring-to-static-assets-from-link-href) on how to make sure these files get included into the builds. For example, you can replace `<link href="/src/favicons/favicon-32.png">` with `<link href="./src/favicons/favicon-32.png">`, and then Webpack will recognize it and include it into the build.
If you referenced some other files from `index.html`, please file an issue to discuss your use case. In the meantime, you can serve them from a separate static server until your use case is supported.
## 0.3.1 (September 2, 2016)
### Build Dependency (`react-scripts`)
* Bumps Jest dependency to fix a few issues discovered yesterday. ([@cpojer](https://github.com/cpojer) in [facebook/jest#1580](https://github.com/facebook/jest/pull/1580), [@insin](https://github.com/insin) in [facebook/jest#1574](https://github.com/facebook/jest/pull/1574))
### Migrating from 0.3.0 to 0.3.1
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.3.1
```
## 0.3.0 (September 1, 2016)
### Build Dependency (`react-scripts`)

* Static files such as CSS, images, and fonts, can now exist outside `src` directory. ([@fson](https://github.com/fson) in [#504](https://github.com/facebookincubator/create-react-app/pull/504))
* **Breaking Change:** Local paths in `<link href>` in `index.html` will now be correctly resolved, so deleting `favicon.ico` is not an error anymore. ([@andreypopp](https://github.com/andreypopp) in [#428](https://github.com/facebookincubator/create-react-app/pull/428))
* Removed an annoying lint rule that warned for `<div ref={node => this.node = node}>`. ([@mrscobbler](https://github.com/mrscobbler) in [#529](https://github.com/facebookincubator/create-react-app/pull/529))
* Temporarily disabled `react-constant-elements` Babel transform because of its bugs. ([@gaearon](https://github.com/gaearon) in [#534](https://github.com/facebookincubator/create-react-app/pull/534))
* Fixed a permission issue with Docker. ([@gaearon](https://github.com/gaearon) in [73c940](https://github.com/facebookincubator/create-react-app/commit/73c940a73205d761230f8d6bf81ecfd460ba28a9))

### Migrating from 0.2.3 to 0.3.0
You may optionally update the global command (it’s not required):
```
npm install -g create-react-app@0.3.0
```
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.3.0
```
#### Breaking Change
Now `favicon.ico` is not treated specially anymore.
If you use it, move it to `src` and add the following line to `<head>` in your HTML:
```html
<link rel="shortcut icon" href="./src/favicon.ico">
```
#### New Feature
Since 0.3.0 added a test runner, we recommend that you add it to the `scripts` section of your `package.json` like this:
```js
// ...
"scripts": {
// ...
"test": "react-scripts test --env=jsdom"
}
```
[Then read the testing guide to learn more about using it!](https://github.com/facebookincubator/create-react-app/blob/master/template/README.md#running-tests)

### Migrating from 0.2.2 to 0.2.3
Update `react-scripts` to point to `0.2.3` in your `package.json` and run `npm install`. You shouldn’t need to do anything else.
Newly created projects will use `0.2.3` automatically. You **don’t** need to update the global `create-react-app` CLI itself. It stays at `0.2.0` for now because it doesn’t have any changes.
## 0.2.2 (August 22, 2016)
### Build Dependency (`react-scripts`)

### Migrating from 0.2.1 to 0.2.2
Update `react-scripts` to point to `0.2.2` in your `package.json` and run `npm install`. You shouldn’t need to do anything else.
Newly created projects will use `0.2.2` automatically. You **don’t** need to update the global `create-react-app` CLI itself. It stays at `0.2.0` for now because it doesn’t have any changes.
## 0.2.1 (August 1, 2016)
### Build Dependency (`react-scripts`)
* Fixes an issue with `npm start` taking a very long time on OS X with Firewall enabled ([@gaearon](https://github.com/gaearon) in [#319](https://github.com/facebookincubator/create-react-app/pull/319))

Newly created projects will use `0.2.1` automatically. You **don’t** need to update the global `create-react-app` CLI itself. It stays at `0.2.0` for now because it doesn’t have any changes.
## 0.2.0 (July 28, 2016)
### Build Dependency (`react-scripts`)

### Migrating from 0.1.0 to 0.2.0
You may optionally update the global command (it’s not required):
```
npm install -g create-react-app@0.2.0
```
Inside any created project that has not been ejected, run:
```
npm install --save-dev --save-exact react-scripts@0.2.0
```
You may need to fix a few lint warnings about missing `<img alt>` tag, but everything else should work out of the box. If you intend to deploy your site to GitHub Pages, you may now [add `homepage` field to `package.json`](https://github.com/facebookincubator/create-react-app/blob/master/template/README.md#deploy-to-github-pages).
