So, it's June @Staff.
How far are we from full tls-crypt and IPV6 support?
We are very near. Now servers supporting IPv6 and tls-crypt are twelve and no specific problems are detected. We call such servers "Generation 2" servers, and you can see them in Eddie or in the Configuration Generator by selecting the proper options.
When Eddie 2.14.x reaches the stable release, we will allow some more time to get out of the experimental phase and upgrade (gradually, because it requires disconnection of all clients) every server to Generation 2.
Only a tiny amount of servers (less than 7-8) will not support IPv6 because the datacenter does not have an IPv6 infrastructure. They will support anyway tls-crypt
