This file gives a brief overview of the major changes between each arp-scan
release.  For more details please read the ChangeLog file.

2013-11-24 arp-scan 1.9.2

* Updated IEEE OUI and IAB MAC/Vendor files.  There are now XXXXX OUI entries
  and XXXX IAB entries.

* Added new --plain (-x) option to surpress printing of header and footer text,
  and only display one output line for each responding host. Idea from Stefan
  Tomanek's arp-scan fork on github at https://github.com/wertarbyte/arp-scan.

* Use LWP::UserAgent instead of LWP::Simple in get-oui and get-iab to enable
  the raw content to be obtained, which avoids Unicode/UTF-8 issues.

* Added arp-finherprint patterns for WIZnet W5100 and Cisco IOS 15.0.

* Moved arp-scan development from internal SVN repository to github at
  https://github.com/royhills/arp-scan. The move to git means that the commit
  object names are now SHA1 hashes instead of increasing integer values. So
  they are longer suitable for internal file versions with rcsid variables.
  Accordingly the rcsid varable have been removed.

2013-07-24 arp-scan 1.9:

* Updated IEEE OUI and IAB MAC/Vendor files.  There are now 18157 OUI entries
  and 4414 IAB entries.

* Use autoconf 2.69 and automake 1.11 to add support for ARM 64-bit CPUs.

* Use libpcap functions to obtain the interace IP address and send the ARP
  packet, instead of using our own link-layer specific functions. The only
  link-layer specific function that we still need is get_hardware_address()
  to obtain the interface MAC address. This means we now require libpcap 0.9.3
  or later.

* Added support for Dragonfly BSD.

* The -u option to get-iab and get-oui scripts now works.

* get-oui and get-iab scripts now get the OUI and IAB files from the new
  locations on the IEEE website, and allow whitespace at the beginning of
  the line.

* If the MAC/Vendor file locations are not explicitly specified, look for them
  in the current directory and then in their default location.

* Raised default timeout from 100ms to 500ms.

* Added new --rtt (-D) option to display the packet round-trip time.

* Include <net/bpf.h> header file early in link-bpf.c to avoid BPF symbol
  problems on some BSD based operating systems.

* Added arp-fingerprint patterns for GNU/Hurd, Amazon Kindle (Linux 2.6),
  BeOS, Windows 8, Recent Linux, FreeBSD, NetBSD and OpenBSD versions, and
  RiscOS.

* Added data file "pkt-custom-request-vlan-llc.dat" to the tarball to allow
  the ARP request packet generation self test to complete successfully.

* Various minor bug fixes and improvements.

2011-03-01 arp-scan 1.8:

* Updated IEEE OUI and IAB MAC/Vendor files.  There are now 14707 OUI entries
  and 3542 IAB entries.

* Added support for trailer ARP replies, which were used in early versions
  of BSD Unix on VAX.

* Added support for ARP packets with both 802.1Q VLAN tag and LLC/SNAP framing.

* The full help output is only displayed if specifically requested with
  arp-scan --help.  Usage errors now result in smaller help output.

* Added support for Apple Mac OS X with Xcode 2.5 and later. This allows
  arp-scan to build on Tiger, Leopard and Snow Leopard.

* Changed license from GPLv2 to GPLv3.

* Added warning about possible DoS when setting ar$spa to the destination IP
  address to the help output and man page.

* Added arp-fingerprint patterns for 2.11BSD, NetBSD 4.0, FreeBSD 7.0,
  Vista SP1, Windows 7 and Blackberry OS.

* Enabled compiler security options -fstack-protect, -D_FORTIFY_SOURCE=2 and
  -Wformat-security if they are supported by the compiler. Also enabled extra
  warnings -Wwrite-strings and -Wextra.

* Added new "make check" tests to check packet generation, and packet decoding
  and display.

* Modified get-oui and get-iab perl scripts so they will work on systems where
  the perl interpreter is not in /usr/bin, e.g. NetBSD.

* Various minor bug fixes and improvements.

2008-07-24 arp-scan 1.7:

* new --pcapsavefile (-W) option to save the ARP response packets to a pcap
  savefile for later analysis with tcpdump, wireshark or another program that
  supports the pcap file format.

* new --vlan (-Q) option to create outgoing ARP packets with an 802.1Q VLAN tag
  ARP responses with a VLAN tag are interpreted and displayed.

* New --llc (-L) option to create outgoing ARP packets with RFC 1042 LLC/SNAP
  framing. Received ARP packets are decoded and displayed with either
  LLC/SNAP or the default Ethernet-II framing irrespective of this option.

* Avoid double unmarshalling of packet data: once in callback, then again in
  display_packet().

* New arp-fingerprint patterns for ARP fingerprinting: Cisco 79xx IP Phone
  SIP 5.x, 6.x and 7.x; Cisco 79xx IP Phone SIP 8.x.

* Updated IEEE OUI and IAB MAC/Vendor files.  There are now 11,697 OUI entries
  and 2,386 IAB entries.

2007-04-12 arp-scan 1.6:

* arp-scan wiki at http://www.nta-monitor.com/wiki/
  This contains detailed documentation on arp-scan, and is intended to be
  the primary documentation resource.

* Added support for Sun Solaris.  Tested on Solaris 9 (SPARC).  arp-scan may
  also work on other systems that use DLPI, but only Solaris has been tested.

* New arp-fingerprint patterns for ARP fingerprinting: IOS 11.2, 11.3 and 12.4;
  ScreenOS 5.1, 5.2, 5.3 and 5.4; Cisco VPN Concentrator 4.7; AIX 4.3 and 5.3;
  Nortel Contivity 6.00 and 6.05; Cisco PIX 5.1, 5.2, 5.3, 6.0, 6.1, 6.2, 6.3
  and 7.0.

* Updated IEEE OUI and IAB MAC/Vendor files.  There are now 10,214 OUI entries
  and 1,858 IAB entries.

* Added HSRP MAC address to mac-vendor.txt.

2006-07-22 arp-scan 1.5:

* Reduced memory usage from 44 bytes per target to 28 bytes.  This reduces
  the memory usage for a Class-B network from 2.75MB to 1.75MB, and a Class-A
  network from 704MB to 448MB.

* Reduced the startup time for large target ranges.  This reduces the startup
  time for a Class-A network from 80 seconds to 15 seconds on a Compaq laptop
  with 1.4GHz CPU.

* Added support for FreeBSD, OpenBSD, NetBSD and MacOS X (Darwin). arp-scan
  will probably also work on other operating systems that implement BPF, but
  only those listed have been tested.

* Improved operation of the --srcaddr option.  Now this will change the
  source hardware address in the Ethernet header without changing the
  interface address.

* Additional fingerprints for arp-fingerprint.

* Improved manual pages.

* Updated IEEE OUI and IAB files.  There are now 9,426 OUI entries and 1,568
  IAB entries.

2006-06-26 arp-scan 1.4:

* Added IEEE IAB listings and associated get-iab update script and --iabfile
  option.
* Added manual MAC/Vendor mapping file: mac-vendor.txt and associated
  --macfile option.
* New --localnet option to scan all IP addresses on the specified interface
  network and mask.

2006-06-23 arp-scan 1.3:

* Initial public release.  Source distribution only, which will compile and
  run on Linux.
