version 0.34.9
==============
2009-08-06

- Made build process more platform independent


version 0.34.8
==============
2009-07-29

- Fixed CMake C_FLAGS compiler options for safety checks.


version 0.34.7
==============
2009-07-27

- RTP packet drop count and disorder count (the number of permutations
  needed to regain the correct sequence) are not only printed on the CLI but 
  also in the 9th and 10th columns of the log file.
- Added RTP jitter estimation as specified in RFC3550 (smoothed mean deviation).
  This value is printed on the CLI and in the 5th column of the rtp log-file.
- Fixed -V option with raw layer-2 frames (simulation mode).
- Fixed padding (-p) option (segfault when number too big)
- Fixed some potential stack overflow issues (thanks Vivek!)
  
  

version 0.34.6
==============
2008-12-10

- Added the IP arguments df (don't fragment), mf (more fragments), and rf
  (reserved flag). This makes it easier to build fragmented packets.
  

version 0.34.5
==============
2008-10-30

- Added RTP packet drop count and disorder count (the number of permutations
  needed to regain the correct sequence). These values are printed on the 
  CLI.
- Fixed usage of ranges even when no payload is specified; previously Mausezahn
  had problems with that; error messages include:
   a)  mz/update_DPORT: Can't build TCP header: libnet_build_tcp(): payload
       inconsistency
   b)  mz/update_IP_DA: IP address manipulation failed!
  or similar.
- Updated the INSTALL file.



version 0.34.1
==============
2008-10-08

- Mausezahn now checks system clock precision and chooses monotonic nanosecond
  clock if available or alternative clock otherwise. No nasty warning message 
  should occur anymore.
  
  

version 0.34
============
2008-09-24

- Replaced gettimeofday() with the clock_gettime(CLOCK_MONOTONIC) which does
  not jump when the system syncs via NTP (otherwise artefacts would occur in
  long-term jitter-measurement data; additionally nanosecond precision is 
  (internally) supported, although it is not really required).
- Added IP options 'Loose Source Route' and 'Strict Source Route', as well as
  the possibility to specify any IP option as hexadecimal string.
- IP packets can now be sent without any payload (previously at least a single
  payload byte has been added)
- Added -V option (extended verbose) which prints only frame details but does
  not put anything on the wire.
- Added icmp option echo request (ping), echo reply (default), and unreachable.
  Also made some clean-ups here.


version 0.33.2
==============
2008-09-11

- RTP packets are now (at least more) standard conform. Now Mausezahn per
  default simulates a G.711 codec with 20 msec inter-packet delay and 160 bytes 
  payload. The usage of the timestamps should be correct now so that other
  applications can also interprete Mausezahn's RTP header.
- Added 8 byte padding to BPDU packets (some switches rejected the packet; now
  whole frame is always 60 bytes long (added 8 zero bytes or 4 for PVST+,
  respectively).
- Fixed PVST+ packet format. Should be correct now; can be sent with (default)
  or without 802.1Q tag.
- Better help text for BPDU mode.
- Added 'pvst' as additional keyword for specification of MAC addresses


version 0.33.1
==============
2008-09-04

- Upon startup Mausezahn checks if it has root privileges (getuid, geteuid)
- 'Cleaned' the files README, INSTALL, and AUTHORS, fixed some missing information
  and applied a line wrap at 80 chars to comply with packaging requirements.
- Also made a 80-char line-wrap in the source code's license statement.


version 0.33 
============
2008-08-20

- Clearly defined GPLv2 as license.
- Support for the Syslog protocol.
- Inclusion of cmake for easier build process.
- Some minor bugfixes, e. g. now "mz -t help" works (before you had to enter 
  "mz eth0 -t help").

Thanks to Cristian Greco, Steve Grubb, Rauno Tuul, and Heinz Wiesinger for help
and feedback.




================================================================================

Since I was too lazy to maintain a changelog before version 0.32 let
me summarize at least all features and possible bugs at this point:

*) Full support for the following protocols:

    - ARP
    - BPDU (PVST+)
    - CDP
    - UDP
    - TCP (only transmission, no state machine so far)
    - DNS 
    
*) Limited support:

    - ICMP (started to implement ICMP redirects, did not had time for
            tests so far; almost sure buggy)
	    
    - RTP  (only needed for jitter measurements, the timestamps used
            are quite proprietary (sec and msec separately))

*) Other features

    - can send arbitrary byte sequences longer or equal 15 bytes
    - randomized MAC and/or IP addresses
    - ranges for IP addresses, port numbers, TCP sequence numbers
    - 802.1Q VLAN tags (arbitrary depth) plus CoS values
    - MPLS tags (arbitrary depth) plus CoS and TTL values
    - automatic padding if desired
    - inter-packet delays in usec (but can also be specified in msec
      and sec)
    - text or hex payloads 
    - RTP receiving mode to measure jitter with high precision (usec
      is base, plan to measure true precision empirically, I guess
      it is at least below 1 msec)

*) Possible bugs

    - Limited checks for wrong arguments and options (however, I
      tried to avoid buffer overflows, mostly)
      
    - ICMP packets (redirects) may be incorrect (I had no use for
      those so far)
