+# 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).
+
+## [2.0.0] - 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)

 FileSaver.js
 ============
 
-FileSaver.js implements the `saveAs()` FileSaver interface in browsers that do
-not natively support it. There is a [FileSaver.js demo][1] that demonstrates saving
-various media types.
-
 FileSaver.js is the solution to saving files on the client-side, and is perfect for
-webapps that need to generate files, or for saving sensitive information that shouldn't be
+web apps that generates files on the client, However if the file is coming from the
-sent to an external server.
+server we recommend you to first try to use [Content-Disposition][8] attachment response header as it has more cross-browser compatible
 
 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 data, 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)).
 
 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 synchronously head request
+if it does it will download the data and save it 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.
 
 ### Saving a canvas
 
 ```js
-var canvas = document.getElementById("my-canvas"), ctx = canvas.getContext("2d");
+var canvas = document.getElementById("my-canvas");
-// draw to canvas...
 canvas.toBlob(function(blob) {
     saveAs(blob, "pretty image.png");

+### Saving File
+
+You can save a File constructor without specifying a filename. The
+File itself already contains a name, There is a hand full of ways to get a file
+instance (from storage, file input, new constructor, clipboard event)
+But if you still want to change the name, then you can change it in the 2nd argument
+

+// Note: Ie and Edge don't support the new File constructor,
+// so it's better to construct blobs and use saveAs(blob, filename)
+var file = new File(["Hello, world!"], "hello world.txt", {type: "text/plain;charset=utf-8"});
