 ## 4.0.0
 * Switch to the composer autoloader. Removed the `Tiqr_Autoloader` class. This means you must now use composer to use this library, or add your own autoloading.
 * Remove support for Apple push notifications (APNS) v1, and the Zend Framework 1 dependency that it required. The library now only supports APNS v2.
