Changed

• Deprecated static .env-based configuration in favor of passing a ConfigurationOptions instance to Configuration.php. Also deprecated passing an array of configuration info Configuration.php's constructor for the same reason. The deprecated configuration methods will continue to be supported until v3.0.0. This closes #1. Big thanks to @cpiggott for his help on this!

Fixed

• Request failing when an expired accessToken was passed via Configuration.php
