Dear Knot Resolver users, Knot Resolver 6.0.17 (early-access) has been released! Improvements: - kresctl migrate: new command for migrating the configuration to a newer version (!1672) - manager: basic support for non-Linux systems (macOS, FreeBSD) (!1758) - cache: collect garbage based on usage statistics (!1726) This results in using the cache space better, and in practice it reduces latency especially in case of answers that are *not* fully cached. Incompatible changes: See upgrading guide for incompatible configuration changes: https://www.knot-resolver.cz/documentation/v6.0.17/upgrading.html - Removed options from declarative configuration model (YAML). (!1672, !1754) These are mostly experimental and debugging/testing options that are not useful for general users (remain in Lua): - /dnssec/refresh-time - /dnssec/hold-down-time - /dnssec/time-skew-detection - /dnssec/keep-removed - /local-data/root-fallback-addresses* - /logging/debugging - /max-workers - /network/tls/auto-discovery - /webmgmt - Renamed/moved options in the declarative configuration model (YAML). (!1672) - /cache/garbage-collector -> /cache/garbage-collector/enable - /cache/prefetch/prediction -> /cache/prefetch/prediction/enable - /defer/enabled -> /defer/enable - /dns64: true|false -> /dns64/enable: true|false - /dns64/rev-ttl -> /dns64/reverse-ttl - /dnssec: true|false -> /dnssec/enable: true|false - /dnssec/trust-anchor-sentinel -> /dnssec/sentinel - /dnssec/trust-anchor-signal-query -> /dnssec/signal-query - /logging/dnstap -> /logging/dnstap/enable - /logging/dnssec-bogus -> /dnssec/log-bogus - /monitoring/enabled -> /monitoring/metrics - /monitoring/graphite -> /monitoring/graphite/enable - /network/proxy_protocol -> /network/proxy_protocol/enable - /network/tls/files-watchdog -> /network/tls/watchdog - /rate-limiting -> /rate-limiting/enable - Changed default values in declarative configuration model (YAML). (!1672) - /logging/dnstap/log-queries: true -> false - /logging/dnstap/log-responses: true -> false - /logging/dnstap/log-tcp-rtt: true -> false Full changelog: https://gitlab.nic.cz/knot/knot-resolver/raw/v6.0.17/NEWS Sources: https://secure.nic.cz/files/knot-resolver/knot-resolver-6.0.17.tar.xz GPG signature: https://secure.nic.cz/files/knot-resolver/knot-resolver-6.0.17.tar.xz.asc Documentation: https://www.knot-resolver.cz/documentation/v6.0.17/ -- Ales Mrazek PGP: 3057 EE9A 448F 362D 7420 5A77 9AB1 20DA 0A76 F6DE
