- Version 2.0.25 (unreleased)
        * updated rtclient_read_packet to be compatible with new rt protocol
        * rtclient input now correctly ignores packets with type = RT_MSG

- Version 2.0.24 
        * minor bugs in format_erf
        * applied autoconf to tools/ dir - these are now built and installed
          automatically
        * added --disable-libpacketdump and --disable-tools configure options
        * improved checking for libpcap
        * improved checking for g++ (needed for libpacketdump)

- Version 2.0.23
        * configure fixes for dag
        * set attributes on functions to improve compiler caching
        * include tools/ dir in distributed tar.gz
        * added get_framing_length format function, to return the length
          of any framing headers added by the capture process (eg, pcap or 
          ERF headers)
        * added libpacketdump, a library for dumping out packet information
        * updated tracedump to use libpacketdump, and copied it to the tools/
          directory

- Version 2.0.22
        * Documentation updates
        * Added pcap_dump_flush() replacement function
        * Better doxygen detection
        * Support for legacy DAG POS, ATM and Ethernet formats

- Version 2.0.21
        * fixed error in output erf code, where we were missing 2 bytes
        * will skip vlan headers
        * added trace_decode_uri() function

- Version 2.0.20
        * byte-ordering fixups for WAG
        * writer functions for pcap and wag
        * fix of writer functions for erf
        * format conversion into pcap and erf formats
        * format conversion only applies if input not already in the right
          format
        * move internal fifo* symbols to tracefifo* to prevent collision
          with libfifo

- Version 2.0.19 
        * Move code for different input formats (erf, pcap, wag) into
          separate modules, load and initialise on library load.
        * Add support for primitive trace writing
          See trace_output_create(), trace_output_destroy(), and
          trace_write_packet()
        * Added trace_perror() and libtrace errno functionality.

- Version 2.0.18
        * When opening a trace file, call open() with O_LARGEFILE set and 
          pass the fd into gzdopen/fdopen.
        * Distributions should include man pages and other doxygen generated
          output
        * make install will install man pages into $PREFIX/man/man3
        * fixed some compilation bugs in most of the examples 

- Version 2.0.17
        * Fixed a bug in trace_get_erf_timestamp for the pcap path. 
          Timestamps were not being fabricated correctly. This also
          effected trace_get_seconds, as that calls trace_get_erf_timestamp
          internally.
        * If bpf_setfilter() fails, output the filterstring it failed on
        * Fixed compilation bug under older distributions (woody), where
          the LTLIBOBJS auto* macro wasn't being expanded correctly

- Version 2.0.16
        * Ported to OpenBSD - mad props to meanphil
        * Fixed a bug in the event api where it would die instantly
          for offline traces.
        * Added trace_get_{source,destination}_port
        * Added some constification fixes

- Version 2.0.15b
        * Fix a memory leak
        * Correct calls to trace_get_link to catch a NULL returned
          when an RX error is detected, handle this, and pas it up
          the chain where appropriate
        * Use a pcap callback handler when trace_read_packet() reads from
          a live pcap source. This gives us better diagnostics, such as 
          being able to tell if an error occured. Also fixed a bug under
          FreeBSD where pcap would block until a buffer was full, then
          would let pcap_next iterate over all of them.

- Version 2.0.14
        * Added support for pcap decoding of PPP interfaces (DLT_LINUX_SLL)
          This DLT provides a direction bit, which we make use of in 
          trace_get_direction(). Check the docs for the specifics
        * Fixed a bug where ERF traces weren't being checked for rxerrors.
          If the ERF record indicates an rxerror, then get_link() returns 
          NULL.
        * Removed an extra , which was preventing compilation under gcc 3.4
          in FreeBSD

- Version 2.0.13
        * Improved source docs / doxygen
        * Added functions to retrieve TCP, UDP and ICMP headers encapsulated
          within the IP sublayer
          * get_tcp_from_ip()
          * get_udp_from_ip()
          * get_icmp_from_ip()
        * Added trace_get_next_option to parse TCP/IP options within a
          libtrace_packet object
        

- Version 2.0.12
        * check for IP Fragmentation - if so, don't return TCP header on a
          fragmented packet

- Version 2.0.11 

        * Added in a fallback function for strndup under freebsd. 
          Thanks to mjl for this code.

- Version 2.0.10
        * Removed some badly licensed code.

- Version 2.0.9
        * Added improved conditional codepaths for
                * PCAP 
                * ZLIB
                * BPF
                * DAG
          - These sections of code are only compiled in if there is
            appropriate support for them in the OS / asked by configure.
            In the event of no zlib support, we use a fread interface for 
            uncompressed trace files instead.

- Version 2.0.8
        * Added better configure time checking for pcap-bpf.h (ie, actually fail early if it can't find it or an equivalent)
        * Added trace_set_direction , to set the direction bit in an ERF based trace.
        * Added trace_truncate_packet, to truncate the packet at a specified length


- Version 2.0.7
        * Assorted bugfixes.

- Version 2.0.3 
        * Fixed packet->size bug for pcap

- Version 2.0.2
        * Port to AMD64. Should also work on IA64
        * Will compile cleanly under gcc-2.95 (Debian Woody)
        * Compiles cleanly under FBSD 4.5 and 5.2. 

- Version 2.0.1
        * Port to FreeBSD. Thanks to Phil Murray for testing this

- Version 2.0.0
        * Major API change for cleanup purposes.
                * libtrace_packet_t object used to hold reference to the
                  trace object, the buffer, and assorted variables
        * First autoconf release
        
- Version 1.1.0
        * Tagged as REL_1_1_0
        * First final release tag
