v3.0.0 - Native http2

This version introduces support for the native http2 module in Node.js v8.4.0 or later with fall back to node-spdy in earlier versions of Node.js.

To use the new http2 library you must start your node process with node --expose-http2 and apns2 will automatically use the native module. Later versions of Node.js may expose the native module without the need for a command line flag. In this case, apns2 will automatically use the native module without any additional steps on your end.
