PingTunnel Changelog
====================

0.54 - 1. Feb 2005
- Fixed a byte-order bug (thanks Alfred!)

0.53 - 31. Jan 2005
- Fixed a threading bug, and implemented support for limiting the
  maximum number of tunnels.

Thanks to Alfred Young for reporting and fixing the following bugs:
- Fixed a bug with packets captured via libpcap, where the struct
  sockaddr wasn't properly zeroed.
- Fixed a byte order bug in create_and_insert_proxy_desc.
- Fixed a memory leak in remove_proxy_desc.


0.52 - 3. Jan 2005
- Fixed a problem introduced by the ICMP ID field changes. The 
  proxy didn't retain the ID of the packets received from clients,
  resulting in dropped ICMP packets at the router. This in turn
  lead to the tunnel no longer working, depending on the strictness
  of the router. This version fixes that problem.
- Makefile is better now, thanks to Dries Verachtert.


0.51 - 2. Jan 2005
- Fixed incorrect checksum calculation for resent packets.
- Stopped relying on the ICMP packet's "built-in" ID field,
  and moved the information to the data portion of the packet.
- Changed default verbosity level from debug to verbose.


0.50 - 7. Dec 2004
Initial public release.
