Thanks for the words of gratitude! It’s always nice to hear that the service is helping folks
There’s no plans to do a limited invite-only beta test for the ACME v2 endpoint. We will announce a date in the future where a staging/test instance of the v2 API will be available and anyone that is interested will be able to test.
In the meantime if you’re an ACME client developer and want to start working towards adding ACME v2 support to your client of choice I recommend you check out Pebble. It’s a smaller test server designed to help clients adjust to the V2 API before Boulder and the primary Let’s Encrypt service have public support.
Thanks! Hope this helps,
