-# About this CHANGELOG
-
-This file will include all API breakage, new features, and upgrade info in
-localForage's lifetime.
-
-### [1.5](https://github.com/mozilla/localForage/releases/tag/1.5.0)
-* **Major storage engine change for Safari**: We now use IndexedDB as the storage engine for Saferi v10.1 (and above). This means sites using localForage for data storage with users using Safari `< 10.1` will experience "data loss". In fact no data is lost but the engine will change so localForage will seem empty. You can still force a connection to WebSQL using [localForage's config](https://localforage.github.io/localForage/#settings-api-setdriver) to either keep using your existing WebSQL database or migrate to IndexedDB.
-
-### [1.4.2](https://github.com/mozilla/localForage/releases/tag/1.4.2)
-* Fixes #562.
-
-### [1.4.1](https://github.com/mozilla/localForage/releases/tag/1.4.1)
-* Fixes #520; browserify builds work propertly
-
-### [1.4](https://github.com/mozilla/localForage/releases/tag/1.4.0)
-* Fixes #516; this version should always load the correct driver without that bug.
-
-### [1.3](https://github.com/mozilla/localForage/releases/tag/1.3.0)
-* We now use ES6 for our source code and `webpack` to bundle the `dist/` files.
-
-### [1.2](https://github.com/mozilla/localForage/releases/tag/1.2.0)
-* Iterate through the entire database using `iterate()`. ([#283](https://github.com/mozilla/localForage/pull/283); fixes [#186](https://github.com/mozilla/localForage/pull/186))
-
-### [1.1](https://github.com/mozilla/localForage/releases/tag/1.1.0)
-* Custom drivers can be created using `defineDriver()`. ([#282](https://github.com/mozilla/localForage/pull/282); fixes [#267](https://github.com/mozilla/localForage/pull/267))
-
-### [1.0.3](https://github.com/mozilla/localForage/releases/tag/1.0.3)
-* `config()` accepts a new option: `driver`, so users can set the driver during config rather than using `setDriver()`. ([#273](https://github.com/mozilla/localForage/pull/273); fixes [#168](https://github.com/mozilla/localForage/pull/168))
-
-### [1.0](https://github.com/mozilla/localForage/releases/tag/1.0.0)
-
-* It is no longer necessary to queue commands using `ready()` when using RequireJS. ([723cc94e06](https://github.com/mozilla/localForage/commit/723cc94e06af4f5ba4c53fa65524ccd5f6c4432e))
-* `setDriver` now accepts an array of drivers to be used, in order of preference, instead of simply a string. The string option is still supported. (eg. now one can use `setDriver(['WebSQL', 'localStorage'])` instead of `setDriver('WebSQL')`)
-* node-style, error-first argument method signatures are used for callbacks. Promises don't use error-first method signatures; instead they supply an error to the promise's `reject()` function.
-
-### [0.9](https://github.com/mozilla/localForage/releases/tag/0.9.1)
-
-This release drops support for some legacy browsers, though not actually the
-ones you might think. localForage's new policy is to support the current
-version of all major browsers plus up to three versions back.
-
-* Add built versions without the Promises polyfill to `dist/` directory. ([#172](https://github.com/mozilla/localForage/pull/172))
-* **Drop support for Firefox 3.5. Minimum version is now Firefox 25.** (Technically, Firefox 4+ seems to work.)
-* **Drop support for Chrome 31 and below. Minimum version is now Chrome 32.**
-* Fix a **lot** of bugs. Especially in Internet Exploder.
-* Switch to Mocha tests and test on [Sauce Labs](https://saucelabs.com/).
-* Add a `keys()` method. ([#180](https://github.com/mozilla/localForage/pull/180))
-* Check for localStorage instead of assuming it's available. ([#183](https://github.com/mozilla/localForage/pull/183))
-
-### [Version 0.8](https://github.com/mozilla/localForage/releases/tag/0.8.1)
-
-* Add support for web workers. ([#144](https://github.com/mozilla/localForage/pull/144), [#147](https://github.com/mozilla/localForage/pull/147)).
-
-### [Version 0.6.1](https://github.com/mozilla/localForage/releases/tag/0.6.1)
-
-* Put built versions back in `dist/` directory.
-
-### [Version 0.6.0](https://github.com/mozilla/localForage/releases/tag/0.6.0)
-
-* Add `localforage.config`. ([#40](https://github.com/mozilla/localForage/pull/140))
-* Fix iFrame bug in WebKit. ([#78](https://github.com/mozilla/localForage/issues/78))
-* Improve error handling. ([#60](https://github.com/mozilla/localForage/issues/60))
-* Remove support for `window.localForageConfig`. ([#135](https://github.com/mozilla/localForage/issues/135))
-
-### [Version 0.4](https://github.com/mozilla/localForage/releases/tag/0.4.0)
-
-* Built versions of localForage are now in the top-level directory. ([2d11c90](https://github.com/mozilla/localForage/commit/2d11c90))
-
-### [Version 0.3](https://github.com/mozilla/localForage/releases/tag/0.3.0)
-
-* Check code quality in test suite ([#124](https://github.com/mozilla/localForage/pull/124))
-* `_initDriver()` is called after first public API call ([#119](https://github.com/mozilla/localForage/pull/119))
-
-### [Version 0.2.1](https://github.com/mozilla/localForage/releases/tag/0.2.1)
-
-* Allow configuration of WebSQL DB size ([commit](https://github.com/mozilla/localForage/commit/6e78fff51a23e729206a03e5b750e959d8610f8c))
-* Use bower for JS dependencies instead of `vendor/` folder ([#109](https://github.com/mozilla/localForage/pull/109))
-
-### [Version 0.2.0](https://github.com/mozilla/localForage/releases/tag/0.2.0)
-
-* Add support for ArrayBuffer, Blob, and TypedArrays ([#54](https://github.com/mozilla/localForage/pull/54), [#73](https://github.com/mozilla/localForage/pull/73))
-
-### [Version 0.1.1](https://github.com/mozilla/localForage/releases/tag/0.1.1)
-
-* Added config options to allow users to set their own database names, etc. ([#100](https://github.com/mozilla/localForage/pull/100))
-
----
-
-### March 16th, 2014
-
-* Moved Backbone adapter to its own repository ([b7987b3091855379d4908376b668b4b51a6fedfe](https://github.com/mozilla/localForage/commit/b7987b3091855379d4908376b668b4b51a6fedfe))
-
-### March 13th, 2014
-
-* Changed `localforage.driver` to a function instead of the string directly ([49415145021b0029d2521182de6e338e048fe5b1](https://github.com/mozilla/localForage/commit/49415145021b0029d2521182de6e338e048fe5b1))
-
-### March 4th, 2014
-
-* Changed the IndexedDB database name from `asyncStorage` to `localforage` ([f4e0156a29969a79005ac27b303d7e321a720fc6](https://github.com/mozilla/localForage/commit/f4e0156a29969a79005ac27b303d7e321a720fc6))

-# localForage
-[![Build Status](https://travis-ci.org/localForage/localForage.svg?branch=master)](http://travis-ci.org/localForage/localForage)
-[![NPM version](https://badge.fury.io/js/localforage.svg)](http://badge.fury.io/js/localforage)
-[![Dependency Status](https://img.shields.io/david/localForage/localForage.svg)](https://david-dm.org/localForage/localForage)
-[![npm](https://img.shields.io/npm/dm/localforage.svg?maxAge=2592000)]()
-
-localForage is a fast and simple storage library for JavaScript. localForage
-improves the offline experience of your web app by using asynchronous storage
-(IndexedDB or WebSQL) with a simple, `localStorage`-like API.
-
-localForage uses localStorage in browsers with no IndexedDB or
-WebSQL support. See [the wiki for detailed compatibility info][supported browsers].
-
-To use localForage, just drop a single JavaScript file into your page:
-
-```html
-<script src="localforage.js"></script>
-<script>localforage.getItem('something', myCallback);</script>
-```
-
-Download the [latest localForage from GitHub](https://github.com/localForage/localForage/releases/latest), or install with
-[npm](https://www.npmjs.com/):
-
-```bash
-npm install localforage
-```
-
-or [bower](http://bower.io):
-
-```bash
-bower install localforage
-```
-
-localForage is compatible with [browserify](http://browserify.org/).
-
-[supported browsers]: https://github.com/localForage/localForage/wiki/Supported-Browsers-Platforms
-
-## Support
-
-Lost? Need help? Try the
-[localForage API documentation](https://localforage.github.io/localForage).
-
-If you're stuck using the library, running the tests, or want to contribute
-to localForage, you can visit
-[irc.freenode.net](https://freenode.net/) and head to the `#localforage`
-channel to ask questions about localForage.
-
-The best person to ask about localForage is [**tofumatt**][tofumatt], who
-is usually online from 8am-8pm GMT (London Time).
-
-[tofumatt]: http://tofumatt.com/
-
-## Safari 10.1+
-
-Since Safari 10.1 we default to IndexedDB; see the [CHANGELOG](https://github.com/localForage/localForage/blob/master/CHANGELOG.md) for more info.
-
-# How to use localForage
-
-## Callbacks vs Promises
-
-Because localForage uses async storage, it has an async API.
-It's otherwise exactly the same as the
-[localStorage API](https://hacks.mozilla.org/2009/06/localstorage/).
-
-localForage has a dual API that allows you to either use Node-style callbacks
-or [Promises](https://www.promisejs.org/). If you are unsure which one is right for you, it's recommended to use Promises.
-
-Here's an example of the Node-style callback form:
-
-```js
-localforage.setItem('key', 'value', function (err) {
-  // if err is non-null, we got an error
-  localforage.getItem('key', function (err, value) {
-    // if err is non-null, we got an error. otherwise, value is the value
-  });
-});
-```
-
-And the Promise form:
-
-```js
-localforage.setItem('key', 'value').then(function () {
-  return localforage.getItem('key');
-}).then(function (value) {
-  // we got our value
-}).catch(function (err) {
-  // we got an error
-});
-```
-
-For more examples, please visit [the API docs](https://localforage.github.io/localForage).
-
-## Storing Blobs, TypedArrays, and other JS objects
-
-You can store any type in localForage; you aren't limited to strings like in
-localStorage. Even if localStorage is your storage backend, localForage
-automatically does `JSON.parse()` and `JSON.stringify()` when getting/setting
-values.
-
-localForage supports storing all native JS objects that can be serialized to
-JSON, as well as ArrayBuffers, Blobs, and TypedArrays. Check the
-[API docs][api] for a full list of types supported by localForage.
-
-All types are supported in every storage backend, though storage limits in
-localStorage make storing many large Blobs impossible.
-
-[api]: https://localforage.github.io/localForage/#setitem
-
-## Configuration
-
-You can set database information with the `config()` method.
-Available options are `driver`, `name`, `storeName`, `version`, `size`, and
-`description`.
-
-Example:
-```javascript
-localforage.config({
-    driver      : localforage.WEBSQL, // Force WebSQL; same as using setDriver()
-    name        : 'myApp',
-    version     : 1.0,
-    size        : 4980736, // Size of database, in bytes. WebSQL-only for now.
-    storeName   : 'keyvaluepairs', // Should be alphanumeric, with underscores.
-    description : 'some description'
-});
-```
-
-**Note:** you must call `config()` _before_ you interact with your data. This
-means calling `config()` before using `getItem()`, `setItem()`, `removeItem()`,
-`clear()`, `key()`, `keys()` or `length()`.
-
-## Multiple instances
-
-You can create multiple instances of localForage that point to different stores
-using `createInstance`. All the configuration options used by
-[`config`](#configuration) are supported.
-
-``` javascript
-var store = localforage.createInstance({
-  name: "nameHere"
-});
-
-var otherStore = localforage.createInstance({
-  name: "otherName"
-});
-
-// Setting the key on one of these doesn't affect the other.
-store.setItem("key", "value");
-otherStore.setItem("key", "value2");
-```
-
-## RequireJS
-
-You can use localForage with [RequireJS](http://requirejs.org/):
-
-```javascript
-define(['localforage'], function(localforage) {
-    // As a callback:
-    localforage.setItem('mykey', 'myvalue', console.log);
-
-    // With a Promise:
-    localforage.setItem('mykey', 'myvalue').then(console.log);
-});
-```
-
-## Browserify and Webpack
-
-localForage 1.3+ works with both Browserify and Webpack. If you're using an
-earlier version of localForage and are having issues with Browserify or
-Webpack, please upgrade to 1.3.0 or above.
-
-Webpack will emit a warning about using a prebuilt javascript file which is fine. If you want to remove the warning you should exclude `localforage` from being parsed by webpack using the following conf :
-
-```javascript
-module: {
-  noParse: /node_modules\/localforage\/dist\/localforage.js/,
-  loaders: [...],
-```
-
-## TypeScript
-
-If you have the [`allowSyntheticDefaultImports` compiler option](https://www.typescriptlang.org/docs/handbook/compiler-options.html) set to `true` in your [tsconfig.json](https://www.typescriptlang.org/docs/handbook/tsconfig-json.html) (supported in TypeScript v1.8+), you should use:
-
-```javascript
-import localForage from "localforage";
-```
-
-Otherwise you should use one of the following:
-
-```javascript
-import * as localForage from "localforage";
-// or, in case that the typescript version that you are using
-// doesn't support ES6 style imports for UMD modules like localForage
-import localForage = require("localforage");
-```
-
-## Framework Support
-
-If you use a framework listed, there's a localForage storage driver for the
-models in your framework so you can store data offline with localForage. We
-have drivers for the following frameworks:
-
-* [AngularJS](https://github.com/ocombe/angular-localForage)
-* [Backbone](https://github.com/localForage/localForage-backbone)
-* [Ember](https://github.com/genkgo/ember-localforage-adapter)
-
-If you have a driver you'd like listed, please
-[open an issue](https://github.com/localForage/localForage/issues/new) to have it
-added to this list.
-
-## Custom Drivers
-
-You can create your own driver if you want; see the
-[`defineDriver`](https://localforage.github.io/localForage/#definedriver) API docs.
-
-There is a [list of custom drivers on the wiki][custom drivers].
-
-[custom drivers]: https://github.com/localForage/localForage/wiki/Custom-Drivers
-
-# Working on localForage
-
-You'll need [node/npm](http://nodejs.org/) and
-[bower](http://bower.io/#installing-bower).
-
-To work on localForage, you should start by
-[forking it](https://github.com/localForage/localForage/fork) and installing its
-dependencies. Replace `USERNAME` with your GitHub username and run the
-following:
-
-```bash
-# Install bower globally if you don't have it:
-npm install -g bower
-
-# Replace USERNAME with your GitHub username:
-git clone git@github.com:USERNAME/localForage.git
-cd localForage
-npm install
-bower install
-```
-
-Omitting the bower dependencies will cause the tests to fail!
-
-## Running Tests
-
-You need PhantomJS installed to run local tests. Run `npm test` (or,
-directly: `grunt test`). Your code must also pass the
-[linter](http://jshint.com/).
-
-localForage is designed to run in the browser, so the tests explicitly require
-a browser environment. Local tests are run on a headless WebKit (using
-[PhantomJS](http://phantomjs.org)).
-
-When you submit a pull request, tests will be run against all browsers that
-localForage supports on Travis CI using [Sauce Labs](https://saucelabs.com/).
