* Fri Mar 5 2004 David Parrish <david@dparrish.com> 1.1.0

- Change all strcpy() calls to strncpy() to avoid buffer overflow potential
- Add ICMP host unreachable support
- Logging to syslog if log_file = "syslog:facility"
- Now requires libcli 1.5
- All configuration moves to a config structure
- Ability to modify and write config on the fly through command-line interface
- Config file support is removed, and now handled by the cli
- Show hostname in cli prompt
- Keep current state type for tunnels
- Add uptime command do CLI, which also shows real-time bandwidth utilisation
- Add goodbye command to cluster master, which forces droppping a slave
- Cache IP address allocation, so that reconnecting users get the same address
- Fix tunnel resend timeouts, so that dead tunnels will be cleaned up
- Allocate tunnels and radius without using a linked list which had issues
- Fix some off-by-one errors in tunnel and session and radius arrays
- Save and reload ip address pool when dieing
- Check version and size of reloaded data when restarting
- Remove plugin_config support
- Remove old support for TBF which didn't work anyway. HTB is required to do throttling now.
