A new release of dnscrypt-proxy is available.
In order to route all queries through Tor, just uncomment the following line:
# proxy = "socks5://127.0.0.1:9050"
If you are using dnscrypt instead of DoH, you may also want to force TCP:
force_tcp = true
Query logging has also been improved to include the outcome of each transaction. This is a first step towards providing an API suitable for writing a Pi-Hole-like web interface.
