Wireshark

Segfaults in IP and SNA were fixed, as were asserts produced from building with a non-GNU make. Ethereal will now compile on AIX, and it should find libraries better with its newly-tweaked autoconf script. Also, an ICQ decoder was added, and NTP was modified a bit.

New protocol decoders include BPDU, SNA, RIPng, PIM, Yahoo Messenger and Pager Protocol, NTP, BGP, AFS and RX, and VLAN (802.1q). Many more protocols now have fields that are filterable via Ethereal's display filter engine, the syntax for filtering on byte strings has been extended, protocol decoders that have been updated include IPv6, SMB, OSPF, POP, NBNS, and DNS, the TCP Follow window can now convert from EBCDIC, Ethereal can now read HP-UX's nettl trace-file format and some bugs were fixed as well.

Ethereal can now read traces made from Lucent/Ascend WAN routers and Gzipped trace files of any format, decoders have been added for the Internet Cache Protocol and the Internet Printing Protocol, updated decoders include OSI/CLNP, x.25, lapb, token-ring, ethernet, fddi, token-ring MAC, NetBIOS, NBT, NBIPX, ICMP, and IPX SAP, and printing has been enhanced, as well as the ability to decode packets and capture packets concurrently.

Color routines have been added (you can change the color of the packet summary information using the same syntax used for display filters), the decoders for RSVP, NBNS, Token-Ring, ICMP, and IGMP have been updated, initial support for ATM decoding has been added, a security-related race condition when capturing packets has been removed and many changes to enhance usability have also been made.
