Chirpstack v4 requires a new connector

Chirpstack v4 requires a new connector

I upgraded my test Chirpstack server to Chirpstack v4. Integrations no longer work; I see the POST format is different. To begin with, the device EUI has been changed from 'devEUI' : <base64> to 'deviceInfo.devEui' : <hex string> 

How does one request or possibly help add a connector for Chirpstack v4 ?

Thank you,
Dana

Also: 'objectJSON' has become 'object', Quite a few more differences, examples below:
