  Summary for 1.10.0 libpcap release
    Require, and assume, some level of C99 support in the C compiler
    Require Visual Studio 2015 or later if using Visual Studio
    Add support for capturing on DPDK devices
    rpcap: support rpcap-over-TLS
    Windows: report the system error for PacketSetHwFilter() failures
    Label most APIs by the first release in which they're available
    Add support for getting and setting packet time stamp types
        with Npcap
    Add pcap_init(), and add support for UTF-8 strings, including error
        messages, on Windows
    Improve man pages, including adding backward compatibility notes
    Fix configure script issues, including with libnl on Linux
    Fix CMake issues
    Squelch complaints from Bison about "%define api.pure" being
        deprecated
    Fix some memory leaks, including in pcap_compile()
    Linux: handle systems without AF_INET or AF_UNIX socket support
    Catch invalid IPv4 addresses in filters
    AIX: fix loading of BPF kernel extension
    rpcapd: fix core dumps with invalid configuration file
    Show special Linux BPF offsets symbolically in bpf_image() and
        bpf_dump()
    Add some overflow checks in the optimizer
    Add pcap_datalink_val_to_description_or_dlt()
    Windows: make the snapshot length work even if pcap_setfilter()
        isn't called
    Linux: get rid of Wireless Extensions for turning monitor mode on
    Handle the pcap private data in a fashion that makes fewer
       assumptions about memory layouts (might fix GitHub issue #940
       on ARM)
    Fix "unknown ether proto 'aarp'"
    Fix some issues found by cppcheck.
    Linux: proper memory sync for PACKET_MMAP (may prevent GitHub issue
        #898)
    Remove undocumented and rather old "ether proto" protocols
    Fix some thread safety issues
    Windows: add pcap_handle(), and deprecate pcap_fileno()
    AirPcap: add AirPcap support in a module, rather than using
        WinPcap/Npcap's support for it
    Linux: drop support for libnl 1 and 2.
    Linux: Require PF_PACKET support, and kernel 2.6.27 or later
    Add DLT_LINUX_SLL2
    Add a new filter "ifindex" for DLT_LINUX_SLL2 files and live
        Linux captures
    optimizer: add a hack to try to catch certain optimizer loops
        (should prevent GitHub issue #112)
    Probe CONFIGURATION descriptor of connected USB devices
    macOS: cope with getting EPWROFF from SIOCGIFMEDIA
    Linux: return error on interface going away, but not if it just went
        down
    Windows: fix compilation on Cygwin/MSYS
    Linux: set socket protocol only after packet ring configured,
        reducing bogus packet drop reports
    pcap_findalldevs(): don't sort interfaces by unit number
    Linux: get ifdrop stats from sysfs.
    Fix various security issues reported by Charles Smith at Tangible
        Security
    Fix various security issues reported by Include Security
    rpcapd: on UN*X, don't tell the client why authentication failed
    Linux: when adjusting BPF programs, do not subtract the
        SLL[2]_HDR_LEN if the location is negative (special metadata
        offset)
    Preserve references to metadata when adjusting the program;
        see https://github.com/the-tcpdump-group/tcpdump/issues/480#issuecomment-486827278
    Always return a list of supported time-stamp types, even if only
        host time stamps are supported
    Linux: with a timeout of zero, wait indefinitely
    Linux: clean up support for some non-GNU libc C libraries
    Increase the maximum snaplen for LINKTYPE_USBPCAP/DLT_USBPCAP
    Fix handling of some ioctls that fail with "permission denied" even
        when the ioctl isn't supported at all
    Added support for ICMPv6 types 1-4 as tokens in filters
    Windows: Report PCAP_ERROR_NO_SUCH_DEVICE for a non-existent device
    Windows: return an appropriate error message for device removed or
        device unusable due to a suspend/resume
    BPF: treat both ENXIO (everybody but OpenBSD) and EIO (OpenBSD) as
        meaning "the interface was removed"
    BPF: report "the interface disappeared", not "the interface went
        down", if the interface was removed during a capture
    Linux, Windows: report a warning for unknown link-layer header types
    Create the file in pcap_dump_open_append() if it doesn't exist
    Linux, NPF: have pcap_breakloop() forcibly break out of a sleeping
        capture loop
    Report the DLT description in error messages
    Linux: Add support for DSA data link types
    Linux USB: use the snapshot length to set the buffer size, and set
        the len field to reflect the length in the URB (GitHub issue
        #808)
    rpcapd: allow rpcapd to rebind more rapidly (GitHub issue #765)
    Windows: clean up building DLL
    Fix compilation of pcap-tc.c
    Add Haiku pcap implementation
    Windows: handle CRT mismatch for pcap_dump_fopen()
    Windows: map NdisMediumWirelessWan to DLT_RAW
    rpcap: add some new authentication libpcap error codes for
        specific errors
    rpcap: redo protocol version negotiation to avoid problems with old
        servers (it still works with servers using the old negotiation,
        as well as servers not supporting negotiation)
    rpcap: error handling cleanups
    rpcapd: fix some inetd issues
    Don't assume ARM supports unaligned accesses
    Remove (unused) SITA support here.
    Correctly handle pcapng captures with more than one IDB with a
        snspshot length greater than the supported maximum
