4.0 has not been released, let us be clear about that. We will announce soon
when we think Authoritative 4.0.0, Recursor 4.0.0 and dnsdist 1.0.0 will be
released (more or less, we only release software once it is ready, not just
to keep a release date!).

Also, please know that our own domains and resolvers all run on 4.0 and 1.0.
We trust the stuff.

Simultaneously, if you run the releases that are heading up to 4.0.0/1.0.0
as published on repo.powerdns.com, you will get absolutely dedicated support
from us with every issue you find. I think you have experienced that

This support promise is there since only through actual use will our new
releases become good enough, even though we run thousands of automated tests
on every code change.  

Through this pre-release support program, we now know that dnsdist and auth
1.0/4.0 versions now power major telecommunications networks, university
campuses and leading CDNs. If the software breaks, you would read about it
in the news.

So the official answer is: we'll let you know when the new releases are
formal. And util that time, expect exceptional support for any issues you
might have.

I hope this is helpful!
