validate specially crafted DNSSEC responses (bsc#1219823, bsc#1219826).\n  * Fix reversion in --rev-server introduced in 2.88 which caused\n    breakage if the prefix length is not exactly divisible by 8\n    (IPv4) or 4 (IPv6).\n  * Fix possible SEGV when there server(s) for a particular domain\n    are configured, but no server which is not qualified for a\n    particular domain.\n  * Set the default maximum DNS UDP packet sice to 1232.\n  * Add --no-dhcpv4-interface and --no-dhcpv6-interface for better\n    control over which interfaces are providing DHCP service.\n  * Fix issue with stale caching\n  * Add configurable caching for arbitrary RR-types.\n  * Add --filter-rr option, to filter arbitrary RR-types.\n\n- SLP got dropped, remove config (bsc#1214884)\n","title":"Description
