+# Changelog
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [2.0.2] - 2019-05-14
+
+- Catching an exception on Send (HEAD) ([#534])
+
+## [2.0.0] - 2018-10-17
+
+- Removed eval to resolve CSP ([#465])
+
+## [2.0.0-rc.4] - 2018-10-17
+
+- Don’t throw on module.exports
+
+## [2.0.0-rc.3] - 2018-09-27
+
+- Switch export method
+
+## [2.0.0-rc.2] - 2018-09-26
+
+- Added a changelog.md
+- Reverted `a.click()` to use dispatch with a try-catch ([#465], [#382])
+- Made third argument to an object where you have to pass `{ autoBom: true }`
+  - boolean are depricated but still works
+
+## [2.0.0-rc.1] - 2018-09-26
+
+- saveAs don't return anything
+  - The object that dispatched `writestart progress write writeend` are gone
+  - detecting such features was never possible and nobody seems to use it.
+- Removed the demo folder
+- Removed date/version from top of the file
+- Dosen't crash in web workers ([#449])
+- Support saving urls ([#260] with workarounds for cross origin)
+- Uses babel universal module pattern (UMD) to export the package
+- Provides source map now as well.
+- use a[download] before msSaveAs ([#193], [#294])
+- removed dist from .gitignore (npm uses it if it don't find a .npmignore)
+- autoBom is now reversed so you have to tell when you want to use autoBom ([#432])
+- `a.click()` since there are new and depricated event constructors that works differently ([#382])
+- opens up a new popup (tab) directly for the fallback method since the FileReader is async
+- removed the explicitly MSIE [1-9] check
+- Uses new anchor link for each save (might solve multiple download problems)

 ============

-various media types.

 FileSaver.js is the solution to saving files on the client-side, and is perfect for

 Looking for `canvas.toBlob()` for saving canvases? Check out
 [canvas-toBlob.js][2] for a cross-browser implementation.

 Syntax
 ------
-
+### Import `saveAs()` from file-saver
 ```js
-FileSaver saveAs(Blob/File data, optional DOMString filename, optional Boolean disableAutoBOM)
+import { saveAs } from 'file-saver';
 ```
 
-Pass `true` for `disableAutoBOM` if you don't want FileSaver.js to automatically provide Unicode text encoding hints (see: [byte order mark](https://en.wikipedia.org/wiki/Byte_order_mark)).
+```js
+FileSaver saveAs(Blob/File/Url, optional DOMString filename, optional Object { autoBom })
+```
+
+Pass `{ autoBom: true }` if you want FileSaver.js to automatically provide Unicode text encoding hints (see: [byte order mark](https://en.wikipedia.org/wiki/Byte_order_mark)). Note that this is only done if your blob type has `charset=utf-8` set.
 
 Examples
 --------
 
+### Saving text using `require()`
+```js
+var FileSaver = require('file-saver');
+var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
+FileSaver.saveAs(blob, "hello world.txt");
+```
+
 ### Saving text
 
 ```js
 var blob = new Blob(["Hello, world!"], {type: "text/plain;charset=utf-8"});
-saveAs(blob, "hello world.txt");
+FileSaver.saveAs(blob, "hello world.txt");
 ```
 
+### Saving URLs
+
+```js
+FileSaver.saveAs("https://httpbin.org/image", "image.jpg");
+```
+Using URLs within the same origin will just use `a[download]`.
+Otherwise, it will first check if it supports cors header with a synchronous head request.
+If it does, it will download the data and save using blob URLs. 
+If not, it will try to download it using `a[download]`.
+
 The standard W3C File API [`Blob`][4] interface is not available in all browsers.
 [Blob.js][5] is a cross-browser `Blob` implementation that solves this.
