2               I don't talk about it, I just smoke 'em

    Removed:
      * Don't even try /proc/net/ip_conntrack (compat removed in Linux 4.9)
        /proc/net/nf_conntrack is the only supported back-end (Linux 2.6.20)
      * -?hv

    Changed:
      * autohell-based build system and metadata and rpm .spec -> Makefile
        (Changelog and credits from README went to tags)
      * Error for unopenable /proc/net/nf_conntrack to be reasonable
      * -s and -d parsing and canonicalisation with getaddrinfo(3)
        instead of gethostbyname(3) (also supports IPv6)
      * Print the port if one was given instead of just for tcp|udp
      * Usage string to a standard one
      * -S disables -D and -D disables -S
        (-SD used to simply yield no results)
      * Don't format udp without a no-status as UNREPLIED
      * -N ("NAT-host") -> -G ("Gateway") (-N still accepted as an alias)
      * README for -ng

    Fixed:
      * All errors and warnings (mostly due to being ancient)
      * Extraneous arguments not being ignored
      * A >6-column protocol not having a space after it

    New:
      * Internal and final binary tests
      * Get current addresses for -LR with rtnetlink(7) IFA_ADDRESS
        instead of ioctl(SIOCGIFCONF) (to also get IP6 addresses)
        (they are also normalised for IP6 compatibility)
      * An optional argument to read (or -) instead of /proc/net/nf_conntrack
      * Format ip6 addresses with ports with []
      * Normalise addresses even with -n
      * $NETSTAT_NAT_LOCAL_ADDRS can replace this system's real addresses
      * -g to filter by gateway address (like -s and -d)
      * -r gate and -r gate-port to sort by gateway
      * "NAT-host Address" -> "Gateway Address"
      * Manual
      * -X     (width = max-length ip6 address+port)
      * -X1234 (width = 1234)

    Internal:
      * Licences in REUSE format, SPDX headers, RCS tag deletion
      * chmod -x non-executables
      * Useless header inlined into the TU
      * clang-format
      * Utility functions/data/types staticified, cleaned out
      * New parser for nf_conntrack lines
         tokenise, decode each token,
          instead of strcasestr()ing the whole line once or twice for each field
      * Accept all L4 protocol names by name
        (except "unknown" which, if looked up, is cached)
      * boolification
      * Don't free before exit
      * Connection table char*** -> struct connection* with integer -> named fields
      * Don't overallocate (200-8)*sizeof(void*) for each connection
      * Connections sorted with qsort(),
        instead of some inlined bespoke sorting algorithm
      * If both the protocol and the sort row are the same,
        disambiguate by sorting by all other fields in order
      * Test and build manual PDFs on builds.sr.ht
      * Map IP and port to hostname and service with getnameinfo(3)
        instead of gethostbyaddr(3) &c.
