Dear Knot Resolver users,
Knot Resolver 4.0.0 has been released!
This is a major release with many improvements and also some breaking
changes, please see our upgrading guide:

Those interested in DNS-over-HTTPS are welcome to look for unintentional
Easter Bugs we may have accidentally hidden in our experimental
implementation. Upstream packages with DNS-over-HTTPS support are
available for Debian 9, CentOS 7, Ubuntu 18, Fedora and Arch.
