  Summary for 4.99.0 tcpdump release
    Improve the contents, wording and formatting of the man page.
    Print unsupported link-layer protocol packets in hex.
    Add support for new network protocols and DLTs: Arista, Autosar SOME/IP,
      Broadcom LI and Ethernet switches tag, IEEE 802.15.9, IP-over-InfiniBand
      (IPoIB), Linux SLL2, Linux vsockmon, MACsec, Marvell Distributed Switch
      Architecture, OpenFlow 1.3, Precision Time Protocol (PTP), SSH, WHOIS,
      ZigBee Encapsulation Protocol (ZEP).
    Make protocol-specific updates for: AH, DHCP, DNS, ESP, FRF.16, HNCP,
      ICMP6, IEEE 802.15.4, IPv6, IS-IS, Linux SLL, LLDP, LSP ping, MPTCP, NFS,
      NSH, NTP, OSPF, OSPF6, PGM, PIM, PPTP, RADIUS, RSVP, Rx, SMB, UDLD,
      VXLAN-GPE.
    User interface:
      Make SLL2 the default for Linux "any" pseudo-device.
      Add --micro and --nano shorthands.
      Add --count to print a counter only instead of decoding.
      Add --print, to cause packet printing even with -w.
      Add support for remote capture if libpcap supports it.
      Display the "wireless" flag and connection status.
      Flush the output packet buffer on a SIGUSR2.
      Add the snapshot length to the "reading from file ..." message.
      Fix local time printing (DST offset in timestamps).
      Allow -C arguments > 2^31-1 GB if they can fit into a long.
      Handle very large -f files by rejecting them.
      Report periodic stats only when safe to do so.
      Print the number of packets captured only as often as necessary.
      With no -s, or with -s 0, don't specify the snapshot length with newer
        versions of libpcap.
      Improve version and usage message printing.
    Building and testing:
      Install into bindir, not sbindir.
      autoconf: replace --with-system-libpcap with --disable-local-libpcap.
      Require the compiler to support C99.
      Better detect and use various C compilers and their features.
      Add CMake as the second build system.
      Make out-of-tree builds more reliable.
      Use pkg-config to detect libpcap if available.
      Improve Windows support.
      Add more tests and improve the scripts that run them.
      Test both with "normal" and "x87" floating-point.
      Eliminate dependency on libdnet.
    FreeBSD:
      Print a proper error message about monitor mode VAP.
      Use libcasper if available.
      Fix failure to capture on RDMA device.
      Include the correct capsicum header.
    Source code:
      Start the transition to longjmp() for packet truncation handling.
      Introduce new helper functions, including GET_*(), nd_print_protocol(),
        nd_print_invalid(), nd_print_trunc(), nd_trunc_longjmp() and others.
      Put integer signedness right in many cases.
      Introduce nd_uint*, nd_mac_addr, nd_ipv4 and nd_ipv6 types to fix
        alignment issues, especially on SPARC.
      Fix many C compiler, Coverity, UBSan and cppcheck warnings.
      Fix issues detected with AddressSanitizer.
      Remove many workarounds for older compilers and OSes.
      Add a sanity check on packet header length.
      Add and remove plenty of bounds checks.
      Clean up pcap_findalldevs() call to find the first interface.
      Use a short timeout, rather than immediate mode, for text output.
      Handle DLT_ENC files *not* written on the same OS and byte-order host.
      Add, and use, macros to do locale-independent case mapping.
      Use a table instead of getprotobynumber().
      Get rid of ND_UNALIGNED and ND_TCHECK().
      Make roundup2() generally available.
      Resync SMI list against Wireshark.
      Fix many typos.
