Normal output will report count, protocol, and reason for each group of
ports in an ignored state (usually closed or filtered when there are
more than 25 ports in one of those states).
XML output will contain a consolidated list of port numbers as well.

This was a sockaddr_storage, which is 128 bytes. This is a lot for a
structure that is part of Port. It is now a union of sockaddr_in and
sockaddr_in6, which is 28 bytes. A new set_ip_addr method sets the union
from a sockaddr_storage, where plain assignment was used before.
The sockaddr_storage was introduced in r23778, the first big IPv6 merge.
flag) is received in response. This can be due to an extremely rare TCP feature
known as a simultaneous open or split handshake connection.

Added a reason code: ER_SYN and associated reason string: "split-handshake-syn".
changes. The first is that Port objects don't allocate memory for
service and RPC results unless that information is set. This reduces the
size of a bare Port from 92 to 40 bytes on my machine. The second change
is that PortList now has the notion of a "default port state," which is
the state of any ports that didn't receive a response. These ports don't
need an allocated Port object, which saves a lot of memory in scans
where most ports didn't get a response.
a layer 4 protocol used mostly for telephony related applications.
This brings the following new features:
o SCTP INIT chunk port scan (-sY): open ports return an INIT-ACK
chunk, closed ones an ABORT chunk. This is the SCTP equivalent
of a TCP SYN stealth scan.
o SCTP COOKIE-ECHO chunk port scan (-sZ): open ports are silent,
closed ports return an ABORT chunk.
o SCTP INIT chunk ping probes (-PY): host discovery using SCTP
INIT chunk packets.
o SCTP-specific IP protocol scan (-sO -p sctp).
o SCTP-specific traceroute support (--traceroute).
o The ability to use the deprecated Adler32 algorithm as specified
in RFC 2960 instead of CRC32C from RFC 4960 (--adler32).
o 42 well-known SCTP ports were added to the nmap-services file.
