- 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. - Add COPYING and Changes files
