Release Notes

Fixed

• Join the mDNS multicast group for DNS-SD discovery so responses sent to 224.0.0.251:5353 are received, as required by RFC 6762 5.2 (#315).
• Ignore Known Answers in mDNS query packets during DNS-SD discovery, as required by RFC 6762 7.1; 18.2 defines the query/response bit (#316).
• Ignore mDNS responses from UDP source ports other than 5353 or with a non-zero OPCODE, as required by RFC 6762 6 and 18.3 (#317).
• Correct IPv4 host counts and scanning ranges, including /0, /31, and /32 networks, RFC 3021 2.1 treats both /31 addresses as hosts on point-to-point links (#321).
• DNS-SD service-type enumeration now recognizes PTR owner names regardless of letter case, as required by RFC 1035 2.3.3 (#320).
