+# Changelog
+
+### 8.1.0
+
+* Added Closure compiler type definitions
+
+### 8.0.0
+
+* Polyfill default promise with `finally` if it doesn't exist if you use polyfill.js
+* If using `require` with webpack 2+, you now need to do
+
+```js
+var Promise = require('promise-polyfill').default;
+```
+
+instead of
+
+```js
+var Promise = require('promise-polyfill');
+```
+
+* Removed files /dist/promise.js and /dist/promise.min.js. These files were not used unless you downloaded them directly from the repo. They were not used by ES6 modules, CommonJS or polyfill.js
+  The file lead to issues because they overrode the global Promise by default.
+
+### 7.1.2
+
+* Fixed bug in Node JS Promise polyfill
+
+### 7.1.0
+
+* Added Promise.prototype.finally
+
+### 7.0.2
+
+* Added IE8 compatability back to minify
+
+### 7.0.1
+
+* Fixed a bug in 'catch' keyword in IE8
+* Fixed import error when using `require`
+
+## 7.0.0
+
+* Updated code to ES6 module definitions (thanks Andarist)
+* Added polyfill.js file
+* move compiled files to dist folder
+
+## 6.1.0
+
+* Bug fix for non-array values in `Promise.all()`
+* Small optimization checking for making sure `Promise` is called with `new`
+
+## 6.0.0 Deprecated `Promise._setImmediateFn` and `Promise._setUnhandledRejectionFn`
+
+This allows subclassing Promise without rewriting functions
+
+* `Promise._setImmediateFn(<immediateFn>)` has been deprecated. Use `Promise._immediateFn = <immediateFn>` instead.
+* `Promise._setUnhandledRejectionFn(<rejectionFn>)` has been deprecated. Use `Promise._unhandledRejectionFn = <rejectionFn>` instead.
+  These functions will be removed in the next major version.
+
+### 5.2.1 setTimeout to 0
+
+Fixed bug where setTimeout was set to 1 instead of 0 for async execution
+
+### 5.2.0 Subclassing
+
+Allowed Subclassing. [#27](https://github.com/taylorhakes/promise-polyfill/pull/27)
+
+### 5.1.0 Fixed reliance on setTimeout
+
+Changed possibly unhanded warnings to use asap function instead of setTimeout
+
+## 5.0.0 Removed multiple params from Promise.all
+
+Removed non standard functionality of passing multiple params to Promise.all. You must pass an array now. You must change this code
+
+```js
+Promise.all(prom1, prom2, prom3);
+```
+
+to this
+
+```js
+Promise.all([prom1, prom2, prom3]);
+```
+
+### 4.0.4 IE8 console.warn fix
+
+IE8 does not have console, unless you open the developer tools. This fix checks to makes sure console.warn is defined before calling it.
+
+### 4.0.3 Fix case in bower.json
+
+bower.json had Promise.js instead of promise.js
+
+### 4.0.2 promise.js case fix in package.json
+
+Fixed promise.js in package.json. It was accidently published as Promise.js
+
+## 4.0.1 Unhandled Rejections and Other Fixes
+
+* Added unhandled rejection warnings to the console
+* Removed Grunt, jasmine and other unused code
+* Renamed Promise.js to lowercase promise.js in multiple places
+
+### 3.0.1 Fixed shadowing issue on setTimeout
+
+New version fixing this major bug https://github.com/taylorhakes/promise-polyfill/pull/17
+
+## 3.0.0 Updated setTimeout to not be affected by test mocks
+
+This is considered a breaking change because people may have been using this functionality. If you would like to keep version 2 functionality, set Promise.\_setImmediateFn on `promise-polyfill` like the code below.
+
+```js
+var Promise = require('promise-polyfill');
+Promise._setImmedateFn(function(fn) {
+  setTimeout(fn, 1);
+});
+```
+
+### 2.1.0 Promise.\_setImmedateFn
+
+Removed dead code Promise.immedateFn and added Promise.\_setImmediateFn(fn);
+
+### 2.0.2 Simplified Global detection
+
+Simplified attaching to global object
+
+### 2.0.1 Webworker bugfixes
+
+Fixed Webworkers missing window object
+
+## 2.0.0
+
+**Changed the following line**
+
+```
+module.exports = root.Promise ? root.Promise : Promise;
+```
+
+to
+
+```
+module.exports = Promise;
+```
+
+This means the library will not use built-in Promise by default. This allows for more consistency.
+
+You can easily add the functionality back.
+
+```
+var Promise = window.Promise || require('promise-polyfill');
+```
+
+**Added Promise.immediateFn to allow changing the setImmedate function**
+
+```
+Promise.immediateFn = window.setAsap;
+```
+
+### 1.1.4 Updated Promise to use correct global object in Browser and Node
+
+### 1.1.3 Fixed browserify issue with `this`
+
+### 1.1.2 Updated Promise.resolve to resolve with original Promise
+
+### 1.1.0 Performance Improvements for Modern Browsers
+
+## 1.0.1 Update README.md

+# Promise Polyfill
+
+[![travis][travis-image]][travis-url]
+
+[travis-image]: https://img.shields.io/travis/taylorhakes/promise-polyfill.svg?style=flat
+[travis-url]: https://travis-ci.org/taylorhakes/promise-polyfill
+
+Lightweight ES6 Promise polyfill for the browser and node. Adheres closely to
+the spec. It is a perfect polyfill IE or any other browser that does
+not support native promises.
+
+For API information about Promises, please check out this article
+[HTML5Rocks article](http://www.html5rocks.com/en/tutorials/es6/promises/).
+
+It is extremely lightweight. **_< 1kb Gzipped_**
+
+## Browser Support
+
+IE8+, Chrome, Firefox, IOS 4+, Safari 5+, Opera
+
+### NPM Use
+
+```
+npm install promise-polyfill --save-exact
+```
+
+### Bower Use
+
+```
+bower install promise-polyfill
+```
+
+### CDN Polyfill Use
+
+This will set a global Promise object if the browser doesn't already have `window.Promise`.
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/promise-polyfill@8/dist/polyfill.min.js"></script>
+```
+
+## Downloads
+
+* [Promise](https://raw.github.com/taylorhakes/promise-polyfill/master/dist/polyfill.js)
+* [Promise-min](https://raw.github.com/taylorhakes/promise-polyfill/master/dist/polyfill.min.js)
+
+## Simple use
+
+If you would like to add a global Promise object (Node or Browser) if native Promise doesn't exist (polyfill Promise). Use the method below. This is useful it you are building a website and want to support older browsers.
+Javascript library authors should _NOT_ use this method.
+
+```js
+import 'promise-polyfill/src/polyfill';
+```
+
+If you would like to not affect the global environment (sometimes known as a [ponyfill](https://github.com/sindresorhus/ponyfill), you can import the base module. This is nice for library authors or people working in environment where you don't want
+to affect the global environment.
+
+```js
+import Promise from 'promise-polyfill';
+```
+
+If using `require` with Webpack 2+ (rare), you need to specify the default import
+
+```js
+var Promise = require('promise-polyfill').default;
+```
+
+then you can use like normal Promises
+
+```js
+var prom = new Promise(function(resolve, reject) {
+  // do a thing, possibly async, then…
+
+  if (/* everything turned out fine */) {
+    resolve("Stuff worked!");
+  }  else {
+    reject(new Error("It broke"));
+  }
+});
+
+prom.then(function(result) {
+  // Do something when async done
+});
+```
+
+## Performance
+
+By default promise-polyfill uses `setImmediate`, but falls back to `setTimeout`
+for executing asynchronously. If a browser does not support `setImmediate`
+(IE/Edge are the only browsers with setImmediate), you may see performance
+issues. Use a `setImmediate` polyfill to fix this issue.
+[setAsap](https://github.com/taylorhakes/setAsap) or
+[setImmediate](https://github.com/YuzuJS/setImmediate) work well.
+
+If you polyfill `window.setImmediate` or use `Promise._immediateFn = yourImmediateFn` it will be used instead of `window.setTimeout`
+
+```
+npm install setasap --save
+```
+
+```js
+import Promise from 'promise-polyfill/src/polyfill';
+import setAsap from 'setasap';
+Promise._immediateFn = setAsap;
+```
+
+## Unhandled Rejections
+
+promise-polyfill will warn you about possibly unhandled rejections. It will show
+a console warning if a Promise is rejected, but no `.catch` is used. You can
+change this behavior by doing.
+
+-**NOTE: This only works on promise-polyfill Promises. Native Promises do not support this function**
+
+```js
+Promise._unhandledRejectionFn = <your reject error handler>;
+```
+
+If you would like to disable unhandled rejection messages. Use a noop like
+below.
+
+```js
+Promise._unhandledRejectionFn = function(rejectError) {};
+```
+
+## Testing
+
+```
+npm install
+npm test
+```
