- "src-ip" and "dst-ip" conditions can now use IPv6 addresses/subnets. They must be written in colon-hexadecimal representation and enclosed in square brackets (e.g. [fe80::1]). Addresses #774. - "icmp6" is now a valid protocol for use with "ip-proto" and "header" conditions. This allows signatures to be written that can match against ICMPv6 payloads. Addresses #880. - "ip6" is now a valid protocol for use with the "header" condition. (also the "ip-proto" condition, but it results in a no-op in that case since signatures apply only to the inner-most IP packet when packets are tunneled). This allows signatures to match specifically against IPv6 packets (whereas "ip" only matches against IPv4 packets). - "ip-proto" conditions can now match against IPv6 packets. Before, IPv6 packets were just silently ignored which meant DPD based on signatures did not function for IPv6 -- protocol analyzers would only get attached to a connection over IPv6 based on the well-known ports set in the "dpd_config" table.
