-### Next Version
+### [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.

+# Custom Driver API
+
+You can write your own, custom driver for localForage since **version 1.1**.
+
+## defineDriver
+
+```javascript
+// Implement the driver here.
+var myCustomDriver = {
+    _driver: 'customDriverUniqueName',
+    _initStorage: function(options) {
+        // Custom implementation here...
+    },
+    clear: function(callback) {
+        // Custom implementation here...
+    },
+    getItem: function(key, callback) {
+        // Custom implementation here...
+    },
+    key: function(n, callback) {
+        // Custom implementation here...
+    },

+        // Custom implementation here...
+    },
+    setItem: function(key, value, callback) {
+        // Custom implementation here...
+    }
+}
+
+// Add the driver to localForage.
+localforage.defineDriver(myCustomDriver);
+```
+
+```coffeescript
+# Implement the driver here.
+myCustomDriver =
+  _driver: 'customDriverUniqueName'
+  _initStorage: (options) ->
+    # Custom implementation here...
+  clear: (callback) ->
+    # Custom implementation here...
+  getItem: (key, callback) ->

+    # Custom implementation here...
+  removeItem: (key, callback) ->
+    # Custom implementation here...
+  setItem: (key, value, callback) ->
+    # Custom implementation here...
+
+# Add the driver to localForage.
+localforage.defineDriver(myCustomDriver)
+```
+
+You'll want to make sure you accept a `callback` argument and that you pass
+the same arguments to callbacks as the default drivers do. You'll also want to
+resolve or reject promises. Check any of the [default drivers][] for an idea
+of how to implement your own, custom driver.
+
+The custom implementation may contain a `_support` property that is either
+boolean (`true`/`false`) or returns a `Promise` that resolves to a boolean
+value. If `_support` is omitted, then `true` is the default value. You can
+use this to make sure the browser in use supports your custom driver.
+
+<aside class="notice">
+  These drivers are available to every instance of localForage on the page,
+  regardless of which instance you use to add the implementation.
