[knot-resolver-announce] Upcoming changes in Knot Resolver 5.2.0

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Dear Knot Resolver users, we would like to inform you about certain changes in upcoming Knot Resolver 5.2.0: - - Users of Control sockets API need to terminate each command sent to resolver with newline character (ASCII \n). Correct usage: "cache.stats()\n". Newline terminated commands are accepted by all resolver versions >= 1.0.0. - - Human readable output from Control sockets is not stable and changes from time to time. Users who need machine readable output for scripts should use Lua function "tojson()" to convert Lua values into standard JSON format instead of attempting to parse the human readable output. For example API call "tojson(cache.stats())\n" will return JSON string with "cache.stats()" results represented as dictionary. Function "tojson()" is available in all resolver versions >= 1.0.0. - - DoH served with http module DNS-over-HTTP (DoH) will be marked as legacy and won’t receive any more bugfixes. A more reliable and scalable DoH module will be available instead. The new DoH module will only support HTTP/2 over TLS. - - New releases since October 2020 will contain changes for DNS Flag Day 2020. Please double-check your firewall, it has to allow DNS traffic on UDP and also TCP port 53. See https://dnsflagday.net/2020/ for more information.
